EFFECT OF INTRAOPERATIVE INSPIRED GAS MIXTURES ON POSTOPERATIVE NOCTURNAL OXYGEN SATURATION

Effect of intraoperative inspired gas mixtures on postoperative nocturnal oxygen saturation.

Continuous postoperative nocturnal pulse oximetry was performed in 20 patients undergoing elective cholecystectomy to examine if the composition of anaesthetic gas mixtures affects postoperative gas exchange. The patients were allocated randomly to receive either nitrogen or nitrous oxide during anaesthesia, and oximetry was performed on the night before operation and the first and third nights...

Postoperative supplemental oxygen and high intraoperative inspired oxygen: effect and cause?

Effects of high intraoperative inspired oxygen on postoperative nausea and vomiting in gynecologic laparoscopic surgery.

STUDY OBJECTIVE To assess the efficacy of intraoperative inspired oxygen fractions (FIO(2)) of 0.8 and 0.5 when compared with standard FIO(2) of 0.3 in the prevention of postoperative nausea and vomiting (PONV). DESIGN Prospective, randomized, double-blinded, controlled study. SETTING General hospital, postanesthesia care unit (PACU), and gynecology floor room. PATIENTS 120 ASA physical s...

High intraoperative inspired oxygen does not increase postoperative supplemental oxygen requirements.

BACKGROUND Although a high fraction of inspired oxygen (FIO2) could reduce surgical site infection, there is concern it could increase postoperative pulmonary complications, including hypoxemia. Intraoperative positive end-expiratory pressure can improve postoperative pulmonary function. A practical measure of postoperative pulmonary function and the degree of hypoxemia is supplemental oxygen r...

Effect of cerebral oxygen saturation on postoperative nausea and vomiting in female laparoscopic surgery patients

BACKGROUND The purpose of this study was to investigate effect of cerebral oxygen saturation (SCTO2) on postoperative nausea and vomiting (PONV) in female patients who underwent laparoscopic surgery. METHODS This study included 90 female patients who underwent laparoscopic surgery (60 cases of gynecological operations and 30 cases of gallbladder operations). All patients were allocated into 3...
