Comparison of Blood Gases in Patients during the Reeovery Period / 대한마취과학회지

ABSTRACT

In the present study, an effort was made to evaluate the degree of hypoxemia in the early recovery period with general anesthesia. The patients were chosen in each of the following 3 groups, upper abdominal, lower abdominal and non-abdominal operations. The blood samples were taken preperatively, on arrival and 30 minutes after arrival in the recovery room. The blood gases on arrival showed significant decreases of PaO2 and increases of PaCO2 in all three groups in comparison with the preoperative gases. The blood gases at 30 minutes after arrival showed significant increases of PaO2 from the arrival data, in all three groups however there were no significant differences in Paco2. AS a result of this study, it is suggested that conservative and safe management of patients is better to provide supplement oxygen in the earlyer recovery period to all patients with general anesthesia.
