EKG (MINI)
**Below are mini-EKGs – so boxes represent lead 1-V6, strip at bottom is II or V1
Where to Look
What to Look For
1) Rate
Paper speed- 25 mm/sec
1 small square= 1 mm = 0.04 sec
1 large square= 5 mm= 0.2 sec
2) Rhythm
Sinus: P wave before every QRS; P wave for every
QRS; normal PR interval, normal P-wave axis (up in
lead 1 and aVF)
14
CA RDI O LO G Y
3) Axis
up/up = normal
down/up = RAD
up/down = LAD
4) P wave
Long width, biphasic V1 =
LAE Tall height = RAE
Height >2 small squares
Width > 2.5 small squares
5) PR interval
Long PR = 1st degree AVB
Short PR w/ delta wave = WPW
6) QRS duration
QRS > 120msec, > 3 small squares
Rabbit ears in V1 = RBBB
Rabbit ears in V6 = LBBB
7) QRS voltage
Big R in V1 = RVH
(Other criteria for RVH =
upright T in V1; QR in V3R)
Big R in V6 = LVH
(R+S)(I) + (R+S)(II) + (R+S)(III)
8) ST segment
Horizontal depress. or elev.
> 1mm (use TP baseline)
Downward sloping
T wave axis:

MURMURS
Benign heart murmurs: soft, systolic, ejection-type, vary with position
•Still’s murmur- LLSB-LMSB, low- freq vibratory
•Peripheral pulmonary stenosis of newborn- LUSB-transmits to back
•Venous Hum-clavicular areas, inaudible in supine position
Likely pathologic murmur: cyanosis, systolic murmur grade 3 or above, harsh, holosystolic,
diastolic murmur, abnormal heart sounds, abnormally strong or weak pulses, family history of
structural heart disease or sudden death
•Holosystolic- VSD, MR, TR, PDA
•Diastolic- AR, PR, mitral stenosis, tricuspid stenosis
•Ejection-aortic stenosis, pulmonic stenosis, HOCM
CONGENITAL HEART DEFECTS
Occurs in 0.5-0.8% of live births.
Acyanotic heart defects: volume vs. pressure overload
•Volume overload: ↑ pulmonary to systemic blood flow (Qp :Qs). Eventually leads to left heart
failure and resultant pulmonary edema (high-output failure). Examples: left-to-right shunts
such as VSD or regurgitant lesions.
•Pressure overload: obstruction to flow. Sx depend on location of obstruction (right vs. left
heart failure). Examples: aortic valve stenosis or coarctation of the aorta.
Cyanotic heart defects: ↑ or ↓ pulmonary blood flow
•↑ Qp: no obstruction to pulmonary flow; involves abnormal flow patterns/connections (e.g.
transposition of the great arteries) or mixing of venous and arterial blood (e.g. TAPVR or
truncus arteriosus).
•↓ Qp: obstruction to pulmonary flow with right-to-left shunt.
•Examples: Tetralogy of Fallot or tricuspid atresia
SVT
SVT includes atrial tach, AV nodal tach, and reentrant tach (ex WPW)
•No P waves or abnormal P wave axis or P after QRS
•Regular, rapid – usually > 220 in infants, >180 in older
C AR DIOLOGY
17
SVT MANAGEMENT
Unstable patient (hypotensive, infant w severe CHF): IMMEDIATE CARDIOVERSION
Stable: Vagal maneuvers
•Infant: bag of ice to face for up to 10 seconds, PROTECT EYES
•Older child: bearing down, blow through straw, headstand; avoid carotid massage
If vagal maneuvers fail and still stable: Set up EKG and call PICU or cards
• Adenosine: 100mcg/kg x1, if no effect rpt at 100mcg/kg, can go up to 200mcg/kg- Always admin
with defib pads on
•note: frequent sinus pause! scary for patients!
•complicated to give – needs 3-way stopcock; set up prior to pushing adenosine
•first stop-cock w/adenosine attached, second w/ saline flush
•need to push adenosine FAST- adenosine has 10 sec half life → then immediately push
5-10 mls NS
CHEST PAIN
Rarely cardiac origin in kids.
DDx:
•Cardiac – hypertrophic CM, myo/pericarditis, arrhthymia, coronary artery anomaly,
dissection (Marfan’s)
•Chest wall – costochondritis, precordial catch (better w/ deep breath);
•Pulm – PNA, asthma, PTX, acute chest in SS;
•GI - GERD, esophageal spasms;
•Psych – hyperventilation
Dx: if positive family hx or past medical hx → EKG. If positive HPI or exam → EKG, monitors,

SYNCOPE
Brief loss of consciousness due to lack of blood flow to brain.
Note: syncope pts often have hypoxic jerks until the blood flow to the brain improves – this is not
a seizure!
Workup:
•Good history, exam including neuro (and pupils), orthostatics and EKG.
•CT head is NOT needed unless focal neuro signs or significant head injury from fall.
Vasovagal Syncope
Vasovagal syncope (most common): sympathetic burst followed by parasympathetic activation
leading to profound bradycardia, hypotension.
Dx: History – can have premonitory symptoms. Ex: feeling hot, sweating, lightheadedness, nausea,
vision going black
•Associated with emotional states, prolonged standing, dehydration, hair brushing, going to
the bathroom
•Post-syncope pallor, re-syncope on standing too quickly afterward, hypoxic jerks
occasionally occur
•pt wakes up rapidly upon lying down, can feel dizzy and “not usual self” for several hours
following
Tx: hydration, lie down when feeling lightheaded, nml dietary salt intake, avoidance of stimulants
Cardiac Syncope
Cardiac syncope: due to hypertrophic CM, tachy or bradycardia, aortic stenosis, CHF, etc
•Few preceding sx; usually abrupt onset/offset; occ w/ palpitations but not always!
•May occur during exercise – always worrisome!
Dx: hx, exam, EKG, Holter, echo
Tx: depends on cause; beta blocker for HCM and SVT, etc
SEIZURES
Seizures: urine incontinence (can happen w/vasovagal as well), Postictal confusion, tongue biting, etc
Dx: hx, exam, EEG if convincing hx
Tx: see neuro section

•Thrombocytosis (plts >500K)
•Albumin < 3
•Swelling of hands and feet, redness of
palms and soles
•Elevated AST, ALT
•U/A: sterile pyuria
•Cervical lymphadenopathy- usually
single and unilateral
•LP: aseptic meningitis
Tx:
•IVIG- within first 10 days of illness, 2 g/kg
over 10-12 hours

• Irrigate!!! Leave open: bites > 24 hours old or deep puncture wounds of hand/foot — esp. human
or cat bites.
• Steri-strips OK.
• Never close an infected wound.
• Antibiotics: (augmentin, cefuroxime, or doxycycline) for 5 days with HIGH RISK wounds (hand/
foot bites, puncture wounds, deep or extensive wounds, immunosuppressed or diabetic patients).
• Re-examine within 24-48 hours.

SUTURING
Irrigation
• NS >250cc + 60 cc syringe + 16g angiocath.
• Look for and document any foreign bodies.
• Avoid betadine — may cause tissue necrosis.
Numbing
• Topical LET (lidocaine, epinephrine, tetracaine): Max LET 0.5 ml/10 kg.
• Do not use on distal extremities, nose, or penis!
• Onset: 15 min.
• Duration: 20 min.
Buffered Lidocaine
• Use at room temp.
• Mix: lidocaine w/or without epinephrine (5cc of 2%) + sterile H20/NS (4 cc) + Sodium bicarb (1cc
of 8.4%)
• Onset: Rapid
• Duration: 20 min.
• The max dose of this 1% lidocaine is 4 mg/kg or 0.4cc/kg.
• No epinephrine on digits, nose, or penis!
Needle and Suture Selection
• Consider using steri-strips, Dermabond, or staples.
• Do buried stitches with Dexon (absorbable ­— takes two weeks to dissolve).
• Use Ethilon (nonabsorbable monofilament) on a cutting needle for most superficial suturing: 4-0
to 5-0 for most lacs.
• Plain gut is absorbable and lasts 7 days max, so it is usually only used on face and scalp.
• Do not use chromic gut on the face — it scars!
• Consider 6-0 absorbable plain gut on little kids’ faces; it won’t need to be removed.
• May staple scalp lacerations under hair.
Discharge Advice
• Keep wound clean and dry, covered with antibiotic ointment to prevent scab formation.
• OK to shower, but do not comb hair if scalp laceration.
• Return to MD if signs of infection.
• Later: sunscreen to avoid hyperpigmentation.

ACUTE PAIN CRISIS
•Labs on admission: CBC w/ manual diff, retic panel, chem 18, blood culture, consider ordering
type and cross for 2-4 units and possible post-transfusion electrophoresis
•Orders on admission:
•Ketorolac q6h or other NSAID
•Oral opioid, consider PCA pump if pain is not well controlled
•1.5 X IVMF
•CXR
•Heating pad
•Incentive spirometry
•Miralax if pt will be receiving heavy opioids
•Antihistamine for pruritis
•ALWAYS CHECK FOR PRIAPISM: SURGICAL EMERGENCY IF PRESENT FOR > 4 HOURS
ACUTE CHEST SYNDROME
Most common cause of death in SCD. The development of a new pulmonary infiltrate associated
with fever, chest pain, hypoxia, tachypnea, and cough. Generally caused by infection, infarction, or
fat embolization.
•Acute Chest Syndrome Orders:
•STAT CXR- repeat CXR with any with any respiratory status changes
•Ketorolac Q6H or other NSAID; also consider opioid if pain is not well controlled
•1.5 X IVMF
•Transfuse- 10-20 ml/kg of pRBC’s (see transfusion guidelines) and recheck Hgb 2-4 hours
post-transfusion. Post transfusion should not exceed Hgb > 12 (see formula in transfusion

FEVER AND NEUTROPENIA
Fever and neutropenia is the most common admission for heme/onc that you will get overnight. Be
aware that a neutropenic patient may not have a normal inflammatory response and could become
septic without signs of fever or other classical signs of infection. PE should include dental, nail
beds, perirectal examination, line site visualization. No rectal exams or temperatures. Generally
things that you should do:
•CXR
•Urine culture, blood culture (from port- each lumen)
•Cefepime unless there is a specific indication for another antibiotic- add vancomycin for
cellulitis, PNA, or ill-appearing upon presentation
•Chem10, LFT’s, and CRP
•Tylenol for fever/pain- No motrin until platelets return to greater than 150,000
•IVMF
•Consider LP if any signs of mental status changes (not routine)
•Q24H Bcx for continued fever relapse

COMMUNITY ACQUIRED PNEUMONIA PATHWAY
Diagnostic Studies:
•Order studies only as anticipated to contribute to therapeutic decisions
•For outpatient, no need for CXR or BCx
•CXR (PA/Lat) for In-Pt management to document the presence, size, and character of
parenchymal infiltrates and identify complications of pneumonia
•A chest radiograph interpretation cannot be relied upon to distinguish between viral and bacterial
etiologies
•Blood cultures should be obtained in children requiring hospitalization for presumed bacterial
CAP that is moderate to severe, particularly those with complicated pneumonia
•CBC, CRP or ESR not necessary to empirically treat, nor to differentiate viral vs bacterial
•In selected older children, sputum Gram stain and culture might be helpful
•Nasopharyngeal bacterial cultures are not usually helpful
•If you are considering pertussis, obtain a nasopharyngeal swab or aspirate of the posterior
nasopharynx
•Laboratory confirmation of a viral etiology (e.g., RSV) can occasionally be helpful
•The incidence of bacterial co-infection with RSV pneumonia is low, so when the RSV test is
positive, generally antibiotics are not indicated
•Remember to consider TB and the intradermal TB skin test, or interferon gamma release assay
(Quantiferon) if >4y old
•PCR, serologies and acute phase reactant studies are not usually helpful
Admission Factors:
•Age < 6 months
•SpO2 <92% or marked respiratory distress
•Dehydration with inability to take PO fluids/antibiotics
•Toxic appearance
•complications (empyema/effusions)
•Failed oral antibiotics (48-72hrs)
•Comorbid conditions/ immumocompromised
•Unstable social situation; non-adherence
Outpatient Antibiotic Therapy for suspected Bacterial PNA (Community
Acquired)
•3 mo - 5 years: Amoxicillin 90mg/kg/day BID x 7-10 days
•≥ 5 years: Azithromycin 10mg/kg/day (Day 1), then 5mg/kg/day (Day 2-5)
•+/- Amoxicillin as above
INF E C T IO U S DISEASE
59
Parenteral empiric antibiotics for inpatient treatment of pediatric pneumonia
•Bacterial and fully immunized-Ampicillin (150-200mg/kg/day div q6hr)
•Bacterial and partially immunized-Ceftriaxone (50-100mg/kg/day div q12-24hr)
•If atypical is suspected- Azithromycin (10mg/kg/day, then 5mg/kg/day )
•If complicated or suspect abscess- Clindamycin (30-40mg/kg/day div q6-8hr) , or Vancomycin
(60mg/kg/day div q6hr) if severe disease

ENDOCARDITIS
Diagnostic criteria
2 major criteria, or
1 major criteria and 3 minor criteria, or
5 minor criteria
Major criteria
•2 separate positive blood cultures positive for endocarditis organisms­. Cultures must be drawn
>12 hours apart: Staph aureus,Viridans strep, Strep bovid, HACEK group, enterococci in absence
of primary focus
•Single positive blood culture for Coxiella burnetti
•Echocardiogram evidence of vegetations on valves or implanted devices
Minor criteria
•Predisposing heart condition
•Fever
•Vascular phenomena: arterial emboli, septic pulmonary infarcts, mycotic aneurysm, intracranial
hemorrhage, conjunctival hemorrhage, Janeway’s lesions
•Immunologic phenomena: glomerulonephritis, Osler’s nodes, Roth’s spots, rheumatoid factor
•Micro evidence: positive blood culture for organism not associated with endocarditis
URINARY TRACT INFECTION
Clinical scenario: Consider UTI in any child < 2 years with fever; symptoms non-specific include
abdominal or flank pain, strong-smelling urine, new urinary incontinence, dysuria, urgency,
nausea/vomiting, diarrhea
Additional History: stooling pattern, prenatal ultrasound, potty-training and wiping, sexual
intercourse/abuse, circumcision, recent antibiotics; FHx VUR, recurrent UTI, CKD
Diagnosis: requires positive pure culture; pyelonephritis vs cystitis is clinical (fever, systemic
symptoms, CVA tenderness); febrile infants assumed to have pyelonephritis
UA: positive LE suggestive of WBCs; positive nitrite consistent with urease producing gramnegative bacteria (E. Coli, Klebsiella, Proteus), but poor sensitivity in infants who empty bladder

•25 percent of neonatal disase
•CNS involvement in 60-75% disseminated cases
•Sepsis-like state around day 7 to 14 of life
•Hepatitis and pneumonitis are common findings
•Death from severe coagulopathy, liver dysfunction, and pulmonary involvement
CNS Disease
•One-third of all neonates with HSV infection
•Seizures (both focal and generalized), lethargy, irritability, tremors, poor feeding, temperature
instability, and bulging fontanelle
•Presentation is usually around day 14 to 21 of life
•Can be indistinguishable from other viral and bacterial meningitis
•Should be considered in young infants evaluated for sepsis when bacterial cultures are negative
at 48 to 72 hours and the infant has experienced a worsening or lack of improvement clinically
•Mortality usually is the product of devastating brain destruction neonatal HSV can involve any
and often multiple parts of the brain
SEM Disease
•Infection localized to the skin, eye, and/or mouth
•20-45% of all cases of neonatal HSV disease
•Presentation usually around day 7 to 14 of life

69
ACUTE OTITIS MEDIA TREATMENT ALGORITHM
FOR CHILDREN 6 MONTHS-12 YEARS OF AGE
Based on the 2013 AAP Treatment Guidelines
•Do not diagnose AOM if there is no middle ear effusion
•Mgmt of AOM should include assessment for pain and treatment if pain is present
First line treatment of choice is Amoxicillin (80-90 mg/kg/day divided BID).
•Use Amox/Clav first line if:
•Antibiotics within 30 days or history of recurrent AOM unresponsive to Amox
•Child has AOM with conjunctivitis (likely to be H.influenzae)
Treatment failures (48-72 hours after appropriate treatment): Amox/Clav (if amox used) or
Ceftriaxone (3 doses 50mg/kg). Could consider Clinda with or without 3rd generation cephalosporin.
Tympanocentesis for multiple treatment failures (including Ceftriaxone x 3)
Alternatives for penicillin allergy include Cefdinir and Ceftriaxone. There are no official
recommendations for Type I PCN allergy (could consider Clindamycin with or without Septra).
Azithromycin is not recommended for any scenario in the guidelines

BEFORE CALLING THE PEDIATRIC NEUROLOGISTS
As a part of your excellent H&P, don’t forget to obtain
•Birth history
•Family history (seizure and use of medication and duration of treatment, early wheelchair,
family hx of developmental delays, neuro-genetic syndromes etc)
•Developmental history (when did they meet their milestones, regression)
•Head circumference in children <2yo
EEG’s
Consult Peds Neuro if you think you need an EEG. Order the EEG in CHCS (and Essentris). EEGs
will be approved and scheduled by Peds Neuro (or EEG tech). Read within 24-48 business hours of
the test, and the report documented as an encounter in AHLTA. See phone list for EEG Tech.
You do not need to consult neuro in the case of first time afebrile unprovoked sz. However, let
neurology know about any inpatient EEG so that they can look out for it.
ALTERED MENTAL STATUS

Return to Play:
Each stage should last no less than 24 hours with a minimum of 5 days required to full return. If
symptoms recur, the athlete should stop immediately. Once asymptomatic after at least another 24
hours, resume at the previous asymptomatic level and try to progress again. Multiple concussions
or prolonged symptoms may require a longer rehabilitation.
RETURN TO PLAY GUIDELINES
Rehabilitation Stage
Functional Exercise
1. No activity
Complete physical and cognitive rest.
2. Light aerobic activity
Raise heart rate. Walking, swimming, stationary cycling at 70%
maximum heart rate, no resistance exercises, 5 to 10 minutes.
Absolutely no weightlifting, jumping or hard running.
3. Sport-specific exercise
Specific sport-related drills but no head impact. Moderate jogging,
brief running, moderate-intensity stationary biking, and moderateintensity weightlifting.
4. Non-contact training
drills
More complex drills. Running, high-intensity stationary biking, the
player’s regular weightlifting routine, and non-contact sport-specific
drills. This stage may add some cognitive component to practice
in addition to the aerobic and movement components introduced
above.
5. Full-contact practice

FEBRILE SEIZURE
Definitions/Clinical Findings:
>6mo of age with febrile illness not associated with previous seizures and not meeting criteria for
other acute symptomatic seizure. 50% of children who present with febrile seizures will not have
any identified risk factors (history of fever is first-degree relative, neurodevelopmental delays, HHV6, MMRV or DTaP or influenza vaccines)
TYPES OF FEBRILE SEIZURES
Simple febrile
seizure (75%)
<15min, generalized, 1 episode within 24hr period
Complex febrile
seizure (25%)
>15min, focal component, and/or >1 episode within 24hr period
Diagnostics:
•First simple febrile seizure: no work up unless otherwise clinically indicated.
•Complex febrile seizure: CBC w/ diff, P2, may consider EEG, LP if suspect meningitis/intracranial
infection, neuroimaging if focal
•Routine EEG and neuroimaging are not indicated for first simple febrile seizures. Neuroimaging is
recommended for neurologic deficits, prolonged post-ictal state, and increased ICP.
Management:
•Benzodiazepines/rectal diazepam for prolonged seizure >5min.
•Parent Education: Febrile seizures are the most common seizure disorder in children, affecting
2-5%, between 6-60mo. Recurrence usually occurs within the initial 1-2yrs after initial seizure.
Recurrence risk ~30% if >12mo and ~50% if <12mo at time of initial febrile seizure. Epilepsy
risk ~1% if >12mo and ~2.4% if <12mo after initial febrile seizure. Antipyretics have not shown to
decreased risk of recurrence of simple febrile seizures.

•Partial
paroxysmal change in motor or behavior caused
by abnormal electrical discharges in the brain
one cerebral hemisphere involved
motor signs, sensory, autonomic or psychic experience
•Simple partial - awareness preserved
•Complex partial - awareness impaired, often staring
•Generalized
both cerebral hemispheres involved
•Tonic-clonic, tonic, clonic, atonic, myoclonic, or absence
Epilepsy
2 or more unprovoked seizures >24hrs apart, usually stereotyped
Status epilepticus
single prolonged >30min or series of seizures >30min without full recovery
between events, see PICU section
Neonatal seizure

collapse, syncope, behavioral event (eg. staring), conversion disorder, acute
dystonic reaction, medication withdrawal, night terrors, hypoxia, ischemia,
hyperammonemia, toxin, electrolyte disturbance
Diagnostics:
•consider: POC glucose, P2, VBG, CBC, UA, ammonia, lactate, tox screen, LP. Routine labs in
>6mo who returns to baseline and whose history is non-suggestive is generally not necessary.
•EEG on all first afebrile seizure (most sensitive within 24hrs of seizure). Urgent neuroimaging if
prolonged focal postictal deficit or not back to baseline within few hours.
•Strongly consider non-urgent imaging if cognitive or motor impairment of unknown etiology,
abnormal neuro exam, focal seizure, abnormal/non-benign EEG, or <1yo.
Management:
•AEDs not generally indicated after a first non-febrile seizure. AEDs are recommended after 2 or
more recurrent afebrile seizures.
•Parent Education: Majority of children with first unprovoked afebrile seizure have no or few
recurrences. Recurrence risk ~24% in 1yr, and ~45% over 14yrs.

INVASIVE VENTILATION
Control of rate:
•AC (Assist Control) – minimum rate synchronized to patient triggered breaths; patient triggered
breaths above minimum rate delivers a breath identical to set breaths (see control of volume/
pressure below)
•SIMV (Synchronous Intermittent Mandatory Ventilation) – minimum rate synchronized to patient
triggered breaths; patient triggered breaths above min rate are supported with Pressure Support
•CPAP/PS (Continuous Positive Pressure with Pressure Support Ventilation) – no set rate, all
breaths patient triggered and pressure supported
Control of Volume/Pressure:
•Volume Control (may be AC or SIMV): Breaths supported to provide a pre-determined volume per
breath.
•Pressure Control (may be AC or SIMV): Breaths supported at a pre-determined pressure above
PEEP.
•PRVC (Pressure-Regulated Volume Control; may be AC or SIMV): Provider pre-determined a
volume per breath. Computer adjusts the pressure control to obtain volumes at the target volume.

STATUS ASTHMATICUS
Step 1: Immediately upon arrival in ED
or PICU
•Oxygen
•Steroids: SoluMedrol 2 mg/kg IV (max dose
150 mg) then 1 mg/kg IV q6hr
•Ranitidine 1 mg/kg IV q12hr
•Albuterol: Continuous Albuterol 1 mg/kg/hr
neb; max dose 40 mg/hr
•Do not wean Albuterol unless severe
tachycardia defined as:
•Sustained HR > 220 for children
under 2 years of age
•Sustained HR > 200 for children
aged 2 – 10 years
•Sustained HR > 190 for children
aged 10 – 20 years
•If patient develops sustained tachycardia,
wean Albuterol by 20% q1hr until HR <
maximum rates listed above. No role for
Levalbuterol.
•Atrovent 1 unit dose (500 mcg) neb q6hr only
for children > 6 years of age
•IV fluids: NPO. NS 20 ml/kg IV x 1-3 if signs
of depressed cardiac output then D5 ½NS +
20 mEq/kg KCl at 1-1.5x maintenance.
•Labs: Consider chest X-ray to rule-out
pneumonia or pneumothorax. Blood gas,
chemistry studies, CBC, and other labs are
generally not indicated. May consider EKG
prior to starting Terbutaline.
Step 2: If insufficient response to
step 1 (consider one of more of the
following)
•Terbutaline IV drip
•Start at 1 mcg/kg/min
•MgSO4 40 mg/kg (max 2 g) IV push over 20
minutes
•HeliOx
•Start with 80:20 (80% Helium: 20%
Oxygen)
•Use regulator to increase FiO2 as needed
to maintain SaO2 > 88%
•Use the least amount of O2 required to
maximize Helium concentration
•Ensure mask is tight fitting with high gas
flow rate to ensure pt is not entraining
Nitrogen from the room air
•Ensure that the continuous Albuterol
is running off of HeliOx to maximize
FiHelium.
Step 3: BiPAP via face mask: PEEP
10, PS 15, no rate; adjust setting as
needed
Step 4: Ketamine 1-2 mg/kg IV push
followed by 1-2.5 mg/kg/hr drip
Step 5: Endotracheal intubation with
mechanical ventilation
•Use rate similar to patient’s spontaneous
breathing rate, and attempt to mimic the
patient’s spontaneous inspiratory and
expiratory times. Rapidly transition patient to
Pressure Support mode (i.e., no set rate, no
set inspiratory time) as soon as paralysis is
resolved.
Step 6: Inhaled anesthetics
Step 7: Extra-Corporeal Membrane
Oxygenation (ECMO)
•Double dose q30min to desired effect or
severe tachycardia
•Maximum dose 10 mcg/kg/min
•Check Troponin I levels q6hr

3. Initial fluid resuscitation:
•0.9% normal saline 10-20 cc/kg over 1 hour or faster if in shock
4. Insulin drip: Do not give a bolus.
•Begin with a continuous insulin infusion of 0.1 unit/kg/hr. Do not adjust insulin rate
without discussing with PICU Attending.
5. Fluid therapy:
•Order both standard PICU DKA fluids:
•Bag #1: NS + 20mEq/L of KPhos + 20mEq/L of KAcetate.
•Bag #2: D12.5-NS + 20mEq/L of KPhos + 20mEq/L of KAcetate.
•Total IVF Rate: 1.5 x maintenance
•If glucose is >300, run Bag #1 at 1.5 x maintenance
•Once glucose falls below 300, adjust rate of Bag #1 and Bag #2 to keep glucose 150 –
250. Maintain total rate (Bag #1 + Bag #2) at 1.5 x maintenance
6. Laboratory studies: Order labs per DKA order set
•Glucose every hour
•Chem 10 q 2 hrs for first 6 hours. If stable after 6 hours then q4 hours.
•*Must correct Na for Glc
•EG7 with lytes until HCO3 > 10mM
•Calculate effective osmolality
•OSMeff = 2(sodium + potassium) + glucose/18 (normal range = 280-295 mosm)
•Phosphate and ionized calcium at 6 and 12 hour lab draw.
7. Monitor for complications:
•Cerebral edema, hypophosphatemia, hyponatremia, hypoglycemia, hypokalemia,
hypocalcemia
8. Switch to subcutaneous insulin when pH> 7.30 or HCO3 > 15 and patient is able to tolerate PO.
•Immediately after giving the first subcutaneous insulin injection, discontinue IV fluids
and continuous insulin infusion and allow the patient to eat their meal.

•If infectious cause suspected: Ceftriaxone 100mg/kg +/- Acyclovir 10mg/kg
•If not responsive to benzodiazepines:
•Levetiracetam (Keppra) 30mg/kg IV load
Maintenance of 10-20mg/kg IV Q12 hours
15-45
•Phenobarbital 20mg/kg IV over 20min
May repeat additional 10mg/kg x 2 or more. May require doses above 60mg/kg
•Fosphenytoin 20mg/kg IV over 10min
May repeat additional 10mg/kg
•If still not responsive to pharmacotherapy:
•Pentobarbital coma
5mg/kg IV over 20min, then 0.5-1mg/kg/hr titrated for burst suppression
•Midazolam coma
150-200mcg/kg IV, then 1-10mcg/kg/min
•Consider:
>60
•Continuous EEG
•Head CT
•Lumbar puncture
•Patients in induced coma will likely require intubation and mechanical ventilation.
Intubation is not a treatment for status epilepticus and should only be performed if
necessary. Paralytics used for intubation will mask physical signs of seizures,
however the seizures will continue throughout paralysis and lead to ongoing
neurological damage.

Relationship to gastroesophageal reflux (GER)
•GER is normal event in infants.
•Possible to have evidence of GER and another disorder.
•Reflux induced apnea may be central or related to laryngospasm from local acid effect
Relationship to SIDS
•ALTE may be risk factor for SIDS, especially if required resuscitation
•ALTE peak 1 to 3 months of age
•SIDS peak 3 to 5 months of age
•Apnea of prematurity not a risk factor for SIDS
Conditions not requiring ALTE workup
•Normal child (overreaction to simple choking, gagging, vomiting episode­eyes open and
“bulging”, increased tone) if not sure, consider admission and workup
•Periodic breathing: respiratory pauses 3­20 seconds. Normal in preterm, may persist in term
infants.

URINALYSIS INTERPRETATION
Dipstick
•Color: pink, green, white urine likely secondary to medications (green = propofol), consider UTI
or metabolic errors.
Grossly red urine = hematuria only if microscopy reports RBC too numerous to count
(otherwise think rhabdomyolysis or hemolytic anemic)
118
RE N AL
•Glucose: positive suggests systemic glucose > 180 or proximal tubule defect
•Glucose in the urine does not always mean diabetes (steroids given?)
•Isolated glycosuria with normal serum glucose is commonly due to a different set point for
glucose reabsorption in the proximal tubule, but requires Fanconi’s eval.
•Fanconi syndrome: spill glucose, phosphate, uric acid, bicarb, and amino acids (work up: chem
10 and VBG checked simultaneously with urine phosphate and urine creatine; urine amino acids
any time)
•Bilirubin: reflects elevated serum conjugated bili levels, consider liver or gallbladder disease
•Unconjugated bilirubin is not water soluble, so not excreted in urine
•Ketones: suggests ketosis (using fat instead of glucose for fuel)
•consider serum beta-hydroxybuterate levels
•anorexia, prolonged vomiting, high protein low carb diet, burns, fever, severe illness,
hyperthyroidism, diabetes
•Specific Gravity: depends on number and size of particles, varies with osmolality
• Normal findings: 1.003-1.030
• 1.008: isotonic with plasma (280 mOsm/kg)
•< 1.003: maximally dilute
•After IV contrast given, urine spec grav will go way up for 24-48 hours
•Blood: hematuria, free hemoglobin, or free myoglobin (ie rhabdomyolysis)
•See flowsheet above, hematuria section below
•False positive: semen present in urine
•pH: 4.5-8, reflects systemic acid-base status
•In metabolic acidosis, urine pH should be < 5. If not, consider distal RTA (with proximal RTA,
you can still bring your urine pH < 5)
•pH > 7.5, consider UTI (urease producing, ex: proteus mirabilis) or hypokalemia
•Protein: negative to trace is normal. Trace proteinuria does not need aggressive work up.
•Urobilinogen: formed in intestines by bacteria acting on bilirubin
•High: hemolytic anemia, liver disease
•Low: obstructive jaundice, broad-spectrum antibiotics (loss of intestinal flora)
•Interpret with urine bilirubin (high bilirubin with low urobilinogen suggests obstructive
gallbladder disease, because bili didn’t go into intestines)
•Nitrite: suggests bacteriuria; positive when bacteria able to convert urinary nitrate to nitrite
•False negative: bacteria with minimal nitrate reductase (ex: enterococcus), or minimal dwell time
in the bladder
•Leuko Est: released by WBC and macrophages; dilute urine favors cell lysis and may cause falsepositives (compare to WBC count on microscopy)
•Sterile pyuria (culture negative): consider interstitial nephriits, renal tuberculosis, nephrolithiasis,
Kawasaki, urethritis, non-cath sample
•Clinitest: presence of reducing substance (glucose, lactose, fructose, galactose, pentose)
•If no glucose, consider galactosemia or other inborn error of metabolism
•May be secondary to beta-lactam antibiotics
•Confirm normal newborn screen

*Nephrotic Syndrome: proteinuria, hypoalbuminemia, hyperlipidemia, +/- edema
Causes
To determine glomerular vs tubular proteinuria: microalbumin vs beta-2-microglobulin
1.Glomerular (increased filtration): nephrotic syndrome, glomerulonephritis
•non-pathological: secondary to fever, exercise, seizure, orthostasis
2.Tubular (decreased proximal tubular reabsorption): low molecular weight proteins, Fanconi
syndrome
3.Overflow: very rare in children (multiple myeloma in adults)
Work-up:
•To rule out transient/orthostatic proteinuria, compare first morning sample to QHS sample
•Assess for other findings supportive of renal disease: change in urine volume or color, edema,
hypertension, recent streptococcal infection (pharyngitis in past 2 weeks/dermatitis in past 3
weeks), recent URI/AGE in past 24 hours with new onset gross hematuria (suggests IgAN), family
history of high frequency sensorineural hearing loss or anterior lenticonus (suggests Alport
disease)

2. Arthritis/Arthralgia
3. Abdominal pain / Intussusception
4. Renal disease
DIC, TTP, systemic vasculitis
Varies pending initial complaint
(purpura, joint pain, abdominal pain;
renal disease late)
Typical (diarrhea): Shiga toxin- producing E. coli
(STEC) or Shigella
Atypical (no diarrhea): strep pneumoniae, HIV,
H1N1 influenza; genetic disorders of complement
or cobalamin C, chemotherapy, post-transplant
immunosuppression
Immune-mediated vasculitis
associated with IgA deposition;
variety of infectious and chemical
triggers; undetermined pathogenesis
with immune, genetic, and
environmental factors
Typical HUS (>90%): abdominal pain, vomiting, bloody
diarrhea
May follow bacterial or viral
infection
Pneumococcal: 70% complicated pneumonia, 20-30%
meningitis; consider bactermia, sinusitis, otitis
CBC with peripheral smear (anemia ,
thrombocytopenia, schistocytes, helmet cells), renal
function panel, urinalysis; coag panel (to differentiate
from DIC); infectious studies (stool and blood
culture, CXR, HIV); for atypical, C3, C4, ANA, factor H
mutations
Clinical diagnosis (classic: purpura
on legs and buttocks); consider
skin biopsy if needed (diagnostic if
leukocytoclastic vasculitis with IgA
predominance), serum IgA elevated
in 50-70%
Urinalysis; confirm normal plt and
coag; consider serum creatinine if
abnormal UA
Supportive: PRBC for Hgb < 6, platelets for clinical
bleeding or invasive procedures, fluid/electrolyte
monitoring and management; watch for indications for
acute dialysis
Treatment
Consider Eclulizumab (C5 antibody) for familial HUS,
consider plasmapheresis or plasma infusions
Avoid abx if HUS thought to be due to shiga toxin
Pneumococcal: broad double coverage (cefotaxime,
vancomycin)
Supportive: hospitalization if
inability to orally hydrate, severe
abdominal pain, GI bleeding, altered
mental status, unable to ambulate
due to joint pain; elevated creatinine,
hypertension, or proteinuria
Monitor: blood pressure, urine
output, abdominal exam, stool
guaiac
Consider: NSAIDs, steroids,
abdominal imaging, surgical consult

Outcome
Follow-up
Typical: <5% mortality; hematologic lines recover in
1-2 weeks, followed by renal function recovery; 5-25%
permanent renal disease
Short- and long-term prognosis
excellent, resolves within 1 month;
recurrence in 1/3 (usually less severe
episode), usually within first 4
months
Pneumococcal: more severe initial disease, longer
duration oliguria, requires more transfusions; 12%
mortality, 10% ESRD, 16% CKD
Short-term morbidity from surgical
GI complications (intussception,
usually ileoileal so best diagnosed
by US not by barium enema); longterm from renal disease (20-54%
with renal disease, 90% within first 2
months, more likely if >8yo)
Annual: blood pressure, urinalysis, renal function
panel
Weekly or bi-weekly UA and BP for
4 months, then at subsequent well
checks

Rationale
Review of Systems for atopy
and asthma. (All children with
SCD)
Annually, starting at one year
of age.
If history is positive, refer to
allergy or asthma specialist.
Atopy is a risk factor for
asthma. Children with asthma
and SCD are at increased risk
of vaso-occlusive episodes
(VOE) and ACS.
Assessment of lung function
by spirometry (All children
with SCD)
Annually in all children with
SCD starting at 6 years of age.
With every visit for children
with SCD and asthma, max 4
times per year.
Bronchodilator challenge
should be done in children
with obstruction (FEV1/FVC
less than 95% CI).
Children with SCD may have
obstructive and restrictive
defects.
Starting at 6 years of age:
Every 5 years in children with
no asthma or ACS episodes.
Every 2-3 years in children
with asthma or ACS episodes.
Children with SCD may have
obstructive and restrictive
defects.
Assessment of defects in lung
function by lung volumes with
plethysmography (All children
with SCD)
Treatment of children with
SCD and asthma per NHLBI
guidelines (All children with
SCD)
Review of Systems for Sleep
Disturbed Breathing (Sleep
Apnea) (All children with SCD
and asthma)
Indefinitely. Once diagnosed
with asthma, children should
be assessed at least every
6 months for persistent
symptoms.
Treatment of persistent asthma
in children without SCD with
daily inhaled corticosteroids
is effective in reducing asthma
hospitalizations and symptom
days.
Annually by history.
If history is positive, refer to
pulmonologist for evaluation.
Children with nocturnal
hypoxemia have higher rates
of pain (VOE).
At least annually for children
Appointment with
with SCD and mild asthma.
Pulmonologist, Allergist or
At least every 6 months
Asthma Specialist (All children
for children with SCD and
with SCD and asthma)
moderate to severe asthma.
Children with asthma and SCD
are at increased risk of vasoocclusive episodes (VOE) and
ACS.
Assessment for elevated TR
Jet velocity and pulmonary
hypertension by 2-D
Echocardiography (All
children with SCD)
A tricuspid jet velocity greater
than 2.5 m/s is associated with
an increased risk of death in
adults.
Effective intervention not well
defined.
