Plasma glucose levels in the peri-operative period in children.

Peri-operative plasma glucose levels were studied in one hundred children under 5 years of age and under 20 kg. All underwent procedures of less than 30 minutes. Of 32 cases under the third percentile for weight, ten developed low plasma glucose during the pre-operative and/or postoperative phase. This occurred despite receiving 5% dextrose by mouth 4 hours before induction. Even in children of normal weight there was a low incidence of peri-operative hypoglycaemia. Routine intravenous glucose-containing fluids are thus recommended during the peri-operative period.
