Abstract

Aim: This study aimed at finding the effect of preoperative fasting and preoperative glucose oral fluid on perioperative hypoglycemia and haemodynamics.

Methods: Seventy patients of class 1 and 2 ASA status within 2 and 10 years of age were recruited and randomly divided into two groups of thirty five (35) patients each. Group I patients were kept nil per oral from midnight and Group II patients were given clear glucose (2mls per kilogramme) fluid 2 hours prior to the surgery. All surgeries were done under general anaesthesia plus minus endotracheal intubation with standard monitoring. Standard anaesthesia technique was followed for all the patients. Samples were taken for random blood sugar were taken prior to. and immediately after induction of anaesthesia then at 30mins, an hour and 2hours after. The vital signs were taken. baseline before induction and after induction of anaesthesia every 15mins during the surgery and after surgery. The vital signs preoperatively, at induction and at 30mins, an hour and two hours were analyzed.

Result: The average blood glucose was lower in group A (< 50mg/dl level of hypoglycemia set for this study) when compared to group B. Group A developed more hypoglycaemia and tachycardia while patients who had fluid intake 2hrs prior to surgery did not develop hypoglycaemia and have better haemodynamics.
