The effects of magnesium sulphate on desflurane requirement, early recovery and postoperative analgesia in laparascopic cholecystectomy.

Purpose: we evaluated the effects of magnesium sulphate infusion on anesthetic requirement, early recovery and postoperative analgesia in desflurane-remifentanil-based, balanced anaesthesia.

Methods: 60, ASA (American Society of Anesthesiologists) group 1-2 patients who were scheduled for laparoscopic cholecystectomy were randomly divided into two groups. Before anesthesia, the magnesium-treated group (n = 30) received a 15 min infusion of 40 mg/kg of magnesium sulphate followed by 10 mg/kg/h by continuous i.
