Background: Acute gastroenteritis is a common condition in children characterized by inflammation of the stomach and intestines. The present study was conducted to assess cases of acute diarrhoea with complications in children. Materials & Methods: 65 pediatric patients of acute gastroenteritis of both genders were recorded. Parameters such as duration of illness, signs, and symptoms at admission, vital signs, anthropometry, level of dehydration, biochemical parameters, fluid therapy, antimicrobial therapy, complications, cause of death, and treatment given were recorded. Results: Out of 65 patients, males were 38 and females were 27. Symptoms were poor oral intake in 24 survived and 13 died children, dysentery was seen 36 survived and 8 died, lethargy in 14 survived and 11 died and oliguria 27 survived and 6 died children. Signs of tachycardia was seen in 38 and 14, hypotension in 15 and 8 and pallor in 26 and 15 survived and died children respectively. The difference was significant (P< 0.05). The mean inotropes in first 24 hours was needed in 32 and 12, ventilation in the first 24 hours seen in 26 and 15, RC transfusion in the first 24 hours in 17 and 10 and duration of PICU stay was seen in 5.2 and 4.1 days, blood glucose was 98.4 mg/dl and 96.2 mg/dl, blood urea was 64.2 mg/dl and 58.4 mg/dl, creatinine was 0.9 mg/dl and 0.7 mg/dl and albumin was 3.4 mg/dl and 2.3 mg/dl in survived and died children respectively. Conclusion: Severe acute malnutrition and hypoalbuminemia were associated with increased risk of death. Common symptoms were poor oral intake, dysentery, lethargy and oliguria.
