A safe and effective way to prevent the development of hypoglycaemia in young children during general anaesthesia is to give drinks sweetened with maltose 2 hours before operation. Metoclopramide (Maxolon) is injected intramuscularly to hasten absorption. The postoperative blood sugar in the maltose-treated group (28 patients) was 100+/-22-21 mg/ml (5-5+/-1-232 mmol/litre) and significantly higher ( P less than 0-0005) than in the starved group (22 patients).

A technique of induction of anaesthesia using propanidid, lignocaine and suxamethonium is described, and the muscle fasciculations that follow it are shown to be significantly less than those accompanying induction with methohexitone and suxamethonium.
The actions of intravenous hyoscine butylbromide (Buscopan) and atropine sulphate on reduction of upper respiratory tract secretions during anaesthesia are compared. Hyoscine butylbromide has a significantly more powerful action.
