The chair of pediatrics with children’s surgery, course of children infectious diseases
Methodological Instructions to lesson for 6th year students No 3
(practical classes - 7 hours)
Theme: Acute bowel diseases in children. Toxicosis and exicosis.
Aim: to learn how to diagnose toxicosis and exicosis syndrome in children, determine its
type, period and phase, perform differential diagnosis, and treatment.
Professional motivation: Toxicosis and exicosis are nonspecific generalized answer on
infectious agent or its products in case of massive toxins’ income in blood with
development of endotoxemia. Main pathologic processes in organism are connected with
development of dehydration and loss of electrolytes. Progress of these processes leads to
impairment of blood circulation, hypoxia of tissues, metabolic acidosis, toxic shock
syndrome, and polyorganic insufficiency. That’s why it requires from the doctor to know
diagnostic criterions, duration, treatment and prevention of this pathology.
Basic level
1. To know how to ask complaints, history of the disease and life in children with acute
bowel diseases [propedeutic pediatrics, children infectious diseases].
2. To perform clinical examination of the child with acute bowel disease [propedeutic
pediatrics, children infectious diseases].
3. To diagnose toxicosis with exicosis after clinical, laboratory and instrumental
examination of the child [infectious diseases, propedeutic pediatrics].
4. Pathogenetical and symptomatical treatment of toxicosis with exicosis (pharmacology,
infection diseases).
Students’ independent study program.

Dehydration Dehydration means the body does not have enough fluids to function at an
optimal level. Dehydration can be caused by fluid loss (through vomiting, diarrhea or
excessive urination), inadequate intake, or a combination of both. The most common cause
of dehydration in infants and children is acute gastroenteritis, with its associated vomiting
and diarrhea.

Management of Dehydration
Oral rehydration is effective in case of I-II st. of dehydration in 80-95%.
It is performed in 2 stages by glucose-saline fluids:
І — water-saline deficiency liquidation for the first 4-6 hours after hospitalization (50
ml/kg).
ІІ — maintenance therapy of the fluid loss (80-100 ml/kg for 6-8 hours).
Oral intakes should be small –– 0.5-1 tea spoon every 5-10 minutes. water and saline
fluids correlation is 1:1, in neonates –– 2:1.

Adequate rehydration criterions:
 Improvement of the clinical status;
 Progressive decreasing of dehydration;
Peroral rehydration should be stopped when it is ineffective, edema, oliguria develop.
Parenteral rehydration should be performed in case of:
 Severe dehydration with hypovolemic shock;
 Toxic shock syndrome;
 Combination of exicosis with hard intoxication;
 Oliguria, anuria;
4
 Nonstop vomiting;
 Ineffective peroral rehydration during one day.
Solutions for rehydration should be input in 2 days: 2/3 during the first day, 1/3 –– during
the second. From the third day – supporting of the hydration.

Correlation of IV fluids (water to saline):
 In case of isotonic dehydration –– 1:1;
 In case of hypertonic dehydration –– 2:1 or 3:1;
 In case of hypotonic dehydration –– 1:2.
Start fluids:
 In case of hypertonic dehydration –– 5 % glucose;
 In case of hypotonic dehydration –– 0,9 % NaCl;
 In case of isotonic dehydration –– 10 % glucose.
In case of nonstop vomiting during 4-6 hours fluids should be intake only
parenterally, its’ amount may be 70-80 % of need. The speed of the infusion is: 25 drops
per minute during first hour, 20 drops per minute during second hour, then –– 10-15 drops
per minute.
Correction of the electrolytes:
 Na, Cl deficit – by 0,9 % NaCl not more 100 ml/kg,
 К deficit – 4 % KCl 2-5 ml/kg, or 1-2 ml/kg 7,5 % KCl(1 ml of which is adequate to 1
mmol/l К)
 Mg deficit – 25 % MgSO4 0,75-1,0 ml/kg.
Correction of the toxicosis:
 Oral rehydration in case of toxicosis and exicosis I and II st.;
 Lytic suspension 0,1 ml/kg, seduxen 0,3 mg/kg, prednisone 2-3 mg/kg, dehydration –
lasix 1-2 mg/kg (in case of neurotoxicosis);
 Infusion therapy (toxicosis and exicosis II and III st.);
 hormones IV 5-20 mg/kg per day in 2-4 takes (by prednisone), albumin 5-15 ml/kg,
rheopolyglucin 10-20 ml/kg, trental 0,1-0,2 ml/kg, contrical 1000 U/ kg, heparin 100200 U/ kg (toxic shock syndrome);
 hemodyalis (in case of HUS).
Etiotrope treatment for 5-7 days: – for mild forms – without antibiotics, but furazolidon
10 mg/kg day in 4 doses, or ercefuril (niphuroxazide) may be used; for moderate, severe
(nosocomial) cases – Cefotaxim 100-150 mg/kg/day, Ceftriaxon 100mg/kg/day, or
ciprophloxacin 10-20 mg/kg per day in 2 equal doses. Specific bactheriophage: Children
before 6 months – 10 ml per day; 6 months – 36 months – 20 ml; older than 36 months –
50 ml 5-7 days.

Pathogenetical therapy: - probiotics for 2-3weeks; enterosorption during 5-7 days; diet;
enzymes.
Symptomatic therapy: antipyretics, multivitamins.
Prophylaxis of acute bowel diseases:
- Epidemiological control.
- Isolation and sanation of ill person and carriers.
- Reconvalescent may be discharged from hospital after one negative feces culture (taken
2 days after stop of antibiotic therapy).
- Dispensarisation of reconvalescents for 3 months.
- Feces culture in contacts, carriers.
- Looking after contacts for 7 days without quarantine.
- Disinfection in epidemic focus.
