Perioperative fluid management in paediatric surgical patients has been the focus for considerable interest and debate. The practice of using glucose containing hypotonic maintenance crystalloid solutions for perioperative fluid therapy is being questioned as there have been many case reports of serious morbidity or even death in previously healthy children associated with the administration of i.v. fluids and hospital-acquired hyponatraemia. Recent studies have shown that hypotonic solutions along with stress induced increased secretion of antidiuretic hormone (ADH) perioperatively can lead to hyponatraemic encephalopathy, permanent neurological damage and even death in children. Over the years there is increasing evidence that blood sugars remain high despite using glucose free solutions. The blood sugars may be normal due to endocrine or metabolic stress, so whether or not to use glucose containing fluids intraoperatively remains a controversy. Association of Paediatric Anaesthetists of Great Britain and Ireland consensus guidelines and European consensus statement guidelines recommend intraoperative use of low dextrose (1–2.5%)containing isotonic fluids which have been shown to maintain acceptable blood glucose levels and prevent electrolyte imbalances during surgery. It is not known whether such low glucose-containing fluids maintain blood glucose levels by initiating catabolism of the body’s own stores. The extent to which such a response can be limited by supplying additional glucose without causing undue hyperglycaemia needs evaluation. If adequate carbohydrates are not provided to fasting children it may lead to ketosis.  This study aims to observe relation between perioperative fluid therapy and its effects on glucose and lipid homeostasis.
