Learning Objectives
• Describe current guidelines for the management of
pain, agitation, and delirium in adult patients in the
intensive care unit
• Use validated scales to measure sedation, pain,
agitation, and delirium in critically ill patients

sedatives and analgesics in the acute care,
procedural, and surgical settings

What Is the ABCDE Bundle?
We Need Coordinated Care
• Many tasks and demands on critical care staff
• Great need to align and support the people,
processes, and technology already in ICUs
• ABCDE bundle is multicomponent,
interdependent, and designed to:
– Improve clinical team collaboration
– Standardize care processes
– Break the cycle of oversedation and prolonged
ventilation

Analgosedation
• Analgesic first (A-1), supplement with sedative
• Acknowledges that discomfort may cause agitation
• Remifentanil-based regimen
– Reduces propofol use
– Reduces median MV time
– Improves sedation-agitation scores
• Not appropriate for drug or alcohol withdrawal

Rozendaal FW, et al. Intensive Care Med. 2009;35:291-298.
Analgosedation
• 140 critically ill adult patients undergoing mechanical
ventilation in single center
• Randomized, open-label trial
– Both groups received bolus morphine (2.5 or 5 mg)
– Group 1: No sedation (n = 70 patients) - morphine prn
– Group 2: Sedation (20 mg/mL propofol for 48 h, 1 mg/mL
midazolam thereafter) with daily interruption until awake (n = 70,

• Endpoints
– Primary
 Number of days without mechanical ventilation in a 28-day period

Helpful Approach to
Delirium Management
1. Stop
2. THINK
3. Lastly medicate
Stop and THINK
Do any meds need to be
stopped or lowered?
• Especially consider
sedatives
Toxic Situations
• Is patient on minimal
amount necessary?
Hypoxemia
Infection/sepsis (nosocomial)
Immobilization
Nonpharm interventions
– Daily sedation cessation
– Targeted sedation plan
• Do sedatives need to be
changed?
• CHF, shock, dehydration
• Deliriogenic meds (tight titration)
• New organ failure (liver/kidney)
• Hearing aids, glasses, reorient,
sleep protocols, music, noise
control, ambulation
K+ or electrolyte problems
Delirium
Nonpharmacologic Interventions
• Early mobility – the only nonpharmacologic
intervention shown to reduce ICU delirium1
• Other interventions:
–
–
–
–
Environmental changes (eg, noise reduction)
Sensory aids (eg, hearing aids, glasses)
Reorientation and stimulation
Sleep preservation and enhancement
Schweickert WD, et al. Lancet. 2009;373:1874-1882.
Sleep Abnormalities in the ICU
• More time in light sleep
• Less time in deep sleep
• More sleep fragmentation
There is little evidence that
sedatives in the ICU restore
normal sleep
Friese R. Crit Care Med. 2008;36:697-705.
Weinhouse GL, Watson PL. Crit Care Clin. 2009;25:539-549.
Boosting Sleep Quality in ICU
• Optimize environmental strategies
– Day/night variation, reduce night interruptions, noise reduction
•
•
•
•
•
Avoid benzodiazepines (↓ SWS & REM)
Consider dexmedetomidine (↑ SWS)
GABA receptor agonists (eg, zolpidem)
Sedating antidepressants (eg, trazodone) or antipsychotics
Melatonin
– Pilot: may improve sleep quality of ICU COPD patients

Effect of Common Sedatives

• Benzodiazepines

↓ Slow wave sleep (SWS) and REM
• Propofol
↑ Total sleep time without enhancing REM

Possible safety benefits
– Decreased extrapyramidal effects
– Little effect on the QTc interval (except ziprasidone)
– Less hypotension/fewer orthostatic effects
– Less likely to cause neuroleptic malignant syndrome
•
Possible limitations
– No IV formulations available
– Little published experience in ICU patients
– Troublesome reports of adverse events but most associated with
prolonged use in non-delirium patients

Before Considering a Pharmacologic
Treatment for Delirium…
• Does your patient have delirium?
– Assessed with scale?
• Which type of delirium?
– Hyperactive
– Hypoactive
– Mixed hyperactive-hypoactive
• Have the underlying causes of delirium been identified
and reversed/treated?
• Have non-pharmacologic strategies been optimized?

Antipsychotic Therapy
Rule Out Dementia
• Antipsychotic drugs are not approved for the
treatment of dementia-related psychosis
– No drug is approved for dementia-related psychosis
• Elderly patients with dementia-related psychosis
treated with antipsychotic drugs are at an increased
risk of death
• Physicians considering antipsychotics for elderly
patients with dementia-related psychosis should
discuss this increased risk of mortality with their
patients, patients’ families, and caregivers

PICS Checklist: Have We….
• Limited sedation?
• Changed goals from "arouseable" to "cognitively engaged“
• Promoted early physical and cognitive activity to engage the
brain?
• Treated pain first and used benzodiazepines only when
necessary?
• Limited drugs that block memory (exception: AWS)?
• Assessed and treated pts with alcohol dependency?
• Encouraged family involvement (for both the health of the pt
and the family)?
• Performed a thorough medication reconciliation?
PICS Checklist: Have We….
• Communicated with the pt and family to support psychological wellbeing?
• Offered pt care conferences when indicated?
• Translated/interpreted when indicated?
• Maintained glycemic control without causing hypoglycemia?
• Encouraged uninterrupted sleep at night and for at least 2 hours in the
afternoon?
• Assured that the pt who has dentures and glasses wears them when
conscious?
• Assessed for delirium?
• Noted the presence of delirium in the progress notes for coding and
communication?
• Considered maintaining a pt diary of key events to share with the family?
PICS Hand-Off Checklist
• Have we coordinated care prior to transfer?
– Referred cognitive issues to speech therapy/OT (taught pt/family
cognitive recovery exercises)
– Referred psychiatric issues to psych consult (taught pt/family
coping strategies)
– Referred physical issues to PT (promoting physical activity that
engages the brain)
– Discussed with family lasting effects of illness and the possible
need for continued care (assured them that this is common, and
will take time to resolve)
– Recorded current physical, cognitive and psychological issues,
informed next provider?

General Barriers to
Changing the ICU Culture
• Tendency to maintain the status quo
• Resistance of independent groups to alter their
behaviors and relinquish some autonomy
• Perceived disproportionality of outcomes from the
proposed change to the efforts required for change
• Lack of significant prioritization
• Insufficient personal accountability for completing
change
• Inadequate knowledge about clinical outcomes

Quality Improvement Project:
Implementing ABCDE
• Multidisciplinary team focused on reducing heavy
sedation, using SAT-SBT protocol and increasing MICU
staffing to include full-time physical and occupational
therapists with new consultation guidelines
• Results:
– Delirium decreased
– Sedation use decreased
– Physical mobility improvement
– Decrease hospital length of stay
– Increased MICU admissions

Key Steps for Effective Change
• Linking effective care processes with hospital and
long-term patient outcomes
• Creating a strategy to improve teamwork and
collaboration
• Creating a process for early mobilization
• Recognizing that current practice patterns may
interfere with mobility
• Agreeing on a need to change
• Identification of a local champion

Conclusions
• Oversedation in the ICU is common; associated with
negative sequelae
• Analgosedation has been shown to improve outcomes;
consider sedation only if necessary
• Use the ABCDE protocol
• Titrate all sedative medications using a validated
assessment tool to keep patients comfortable and
arousable if possible
• Use of benzodiazepines should be minimized
Conclusions
• Consider nonpharmacological management of
delirium and reduce exposure to risk factors
• Typical and atypical antipsychotic medications may
be used to treat delirium if nonpharmacological
interventions are not adequate
• Early mobility in ICU patients decreases delirium and
improves functional outcomes at discharge
