A comparative study of the antiemetic efficacy of dexamethasone, ondansetron, and metoclopramide in patients undergoing gynecological surgery.

Background: Postoperative nausea and vomiting (PONV) are some of the most-common and undesirable adverse effects after surgery performed under general anesthesia. We investigated the prophylactic value of dexamethasone as an alternate to ondansetron or metoclopramide to prevent PONV after gynecologic surgery.

Material/methods: One hundred sixty ASA I-II patients scheduled for elective gynecologic surgery were enrolled.

Postoperative effects of low-dose intrathecal morphine in coronary artery bypass surgery.

Background: Intrathecal morphine has been used in hopes of providing long-lasting postoperative analgesia in patients after cardiac surgery. The aim of this study was to evaluate the effects of 7 micro/kg intrathecal morphine administration in coronary bypass surgery in the postoperative period.

Methods: We conducted a prospective, randomized, blinded, and controlled study.

Effects of levosimendan on myocardial ischaemia-reperfusion injury.

Background And Objective: Levosimendan has a cardioprotective action by inducing coronary vasodilatation and preconditioning by opening KATP channels. The aim of this study was to determine whether levosimendan enhances myocardial damage during hypothermic ischaemia and reperfusion in isolated rat hearts.

Methods: Twenty-one male Wistar rats were divided into three groups.
