Résumé / Abstract

Purpose: To study the effects of oxygen administered to patients having cataract surgery under local anesthesia. Setting: The Pretoria Eye Institute, Arcadia, South Africa. Methods: In this prospective study, 31 patients were randomly divided into two groups; one received oxygen inhalation during surgery and the other, air. The saturation of oxygen in arterial blood, the partial pressure of oxygen in arterial blood (PaO₂), the partial pressure of carbon dioxide in arterial blood (PaCO₂), and the pH were evaluated in both groups. Results: The preoperative blood gas parameters were maintained in the air inhalation patients. Oxygen inhalation caused significant increases in the saturation of oxygen in arterial blood and in PaO₂. There was no difference between the two groups in PaCO₂. The pH of arterial blood showed a statistically significant decrease in the oxygen inhalation patients. This shift to more acidotic levels could cause central nervous system depression with reduced respiratory stimulus. Conclusions: We recommend that air rather than oxygen be administered to patients during cataract surgery.
