Randomized Controlled Trial
The effect of supplemental 70% oxygen on postoperative nausea and vomiting in patients undergoing inguinal hernia surgery.
Postoperative nausea and vomiting (PONV) are among the leading side-effects after surgery performed under general anaesthesia. The role of oxygen as an important method for treatment of PONV was studied. The aim of this study was to compare intraoperative 30% oxygen with 70% oxygen for improvement of PONV in patients undergoing inguinal hernia surgery. ⋯ Supplemental oxygen effectively prevents postoperative nausea and vomiting after inguinal hernia surgery: the higher the arterial oxygen saturation, the less frequent PONV.
