Arterial carbon dioxide partial pressure (PaCO2) and pH are basic indices of the adequacy of ventilation in anethatized patients. Previous reports by us and by Frances et al indicate that peripheral venous Pcoa and pH approach values arterial blood during general anesthesia. The present study compares the arterial venous difference for Pco2 and pH during diethyl ether, methoxyflurane and halothane anesthesia in 20 cases each. After induction with thiopental, succinylcholine, the patient was intubated and maintained with N2O-O2 and one of above volatile agents. Venous blood was drawn from the back of the hand and an arterial sample was obtained from the radial artery of the other hand. The results were as follows: 1) The mean arteriovenous Pco2 differences in ether, methoxyflurane and halothane groups were -l. 25, -1. 425 and -0. 065 torr respectively. 2) The mean arterovenous pH differences in each goup were 0. 031, 0, 017and 0. 014 respectively. We conclude from above results that the differences for the arteriovenous Pco2 and pH during halothane anesthesia were less than that of the ether or methoxyflurane groups.
