[Prevention of disorders of the blood acid-base equilibrium after operations on the stomach by prolonged pentamine ganglionic block].

The acid-base balance was studied in 70 patients operated for peptic ulcer. It was shown that during operation metabolic acidosis could develop and in the postoperative period there occurred metabolic alkalosis associated with hypokalemia. The continuous ganglionic blockade without a pentamine-induced hypotension performed by the proposed method was found to prevent shifts of the acid-base balance towards metabolic alkalosis in the postoperative period. The author believes that the favourable effect of the ganglionic blockade on the acid-base balance is related to the reduced hyperreaction of the sympathoadrenal system, adrenals to the operation trauma which prevents "stress" reactions of the patient.
