Carbohydrate and fat metabolism during and after anaesthesia and surgery was studied in 14 neonates with major congenital non‐cardiac anomalies. They were either given a glucose solution until surgery or starved for at least 4 h before surgery. Ringer‐acetate alone or Ringer‐acetate plus 10% glucose was used for the intraoperative fluid therapy. After anaesthesia all neonates were given a 10% glucose solution. Concentrations of glucose, free fatty acids, triglycerides, lactate, pyruvate, alanine, glycerol and 3‐hydroxybutyrate were measured at predetermined intervals pre‐, intra‐ and postoperatively. Blood glucose concentrations rose during surgery both in neonates given glucose before and during surgery (n = 6) and in neonates not given glucose before and during surgery (n = 6). Increased intraoperative levels of free fatty acids and 3‐hydroxybutyrate were found in neonates not given glucose before and during surgery. The triglyceride levels were equal in both groups. In two neonates given glucose before surgery and Ringer‐acetate during surgery increased levels of 3‐hydroxybutyrate were found, particularly in one patient who became hypoglycaemic. In conclusion, starved neonates without intraoperative glucose supply mobilized fat and maintained blood glucose concentrations.
