FINAL DIAGNOSISAcute Gastroenteritis

Adam Safin bin Abdul Mutti2008402544

DefinitionAcute Gastroenteritis :

“diarrheal disease of rapid onset, with or without accompanying symptoms, signs, such as nausea, vomiting, fever, or abdominal pain.”

(American Academy of Paediatrics)

Continue…Diarrhea :

“ abnormal frequency and liquidity of fecal discharges”

(Nelson Pediatrics, 5th edition)

“an increase in the frequency, fluidity and volume of stool compared to normal”

(AMMCOP CPG)

Possible routes of transmissionPerson to person.Contaminated water and food.Animal to human.Multiple routes.

What organism cause AGE???Acute Gastroenteritis

Viruses.

•Rotavirus (most common).•Calicivirus.•Astrovirus.

Bacteria•Campylobacter jejuni.•Salmonella.•Shigella.•E.coli.•Clostridium difficile.

Parasites.•Entamoeba histolytica.•Giardia lamblia.

Clinical ManifestationDiarrhea.Fever.Reduce oral intake.Abdominal pain.Sign and symptoms of dehydration.

Indication of admission.Need for intravenous therapy.Uncertainty of diagnosis.Patient factors (e.g : worsening of symptoms,

young age).Caregivers not able to provide adequate care

at home.Social or logistic concerns.(Paediatric Protocol for Malaysian Hospital, 2nd

edition)

What investigation should be done???Full blood count.Urea and electrolytes.Urinalysis.Stool culture.Blood culture (typhoid fever).

Sign and symptom of dehydration.Reduced level of consciousness.Sunken fontanelle.Dry mucous membrane.Sunken eye and tearless.Reduced skin turgority.Tachypnoea, tachycardia, hypotension.Prolonged CRT ( > 2 seconds)

Sunken fontanelle

Eyes sunken and tearless Reduced skin turgor

Management.To correct the dehydration in patient.

As the main complication of AGE is due to dehydration and its complication.

Thus, assessment of dehydration is very important.

Mild : < 5% dehydration Moderate : 5-10% dehydration. Severe : > 10% dehydration.

TreatmentOral rehydration therapy.

Use to treat mild to moderate dehydration.Consist of :

i. Sodium chloride (NaCl).ii. Potassium chloride (KCl).iii. Trisodium citrate.iv. Glucose.

Continue…i. Mild ( < 5%).

Give ORS.Feed normally.

ii. Moderate ( 5-10%).Give ORS.Small, frequent feeding.Assess hydration status 4 hourly.Fail ORS nasogastric tube.

Continue…iii. Severe ( > 10%).

Medical emergency.Intravenous fluid therapy.a.Resuscitation (normal saline).b.Correction of the deficit (0.45% saline, 4%

dextrose).c.Maintenance (0.18% saline, 4.3% dextrose).

Feeding after AGE???Should be started soon.Avoid fatty foods and foods high in sugars.

Issue???Use of anti-emetics and anti-diarrheal

drugs???Antibiotics???

Type of dehydration

Dehydration.

Isonatraemic.

•Sodium losses = water losses.

Hyponatraemic.•Sodium losses > water loses.•Shift of water to intracellular compartment.•Can lead to convulsion.

Hypernatraemic.•Water losses > sodium losses.•Shift of water to extracellular compartment.•Difficult to recognise clinically.•Multiple,small cerebral hemorrhages.
