Is Obturator Nerve Block Effective as Spinal Anesthesia in Preventing Adductor Spasms in General Anesthesia Without Muscle Relaxants?

Aim: During transurethral resection of bladder tumor (TUR-BT), adductor muscle spasms in varying degrees can be seen due to stimulation of obturator nerve if the tumor is in the inferolateral localization. This can cause some serious complications such as bladder perforation. We aim to show the effectiveness of obturator nerve block (ONB) to avoid the adductor muscle spasm in general anesthesia applied with laryngeal mask (LMA) without using muscle relaxant according to the spinal anesthesia method.

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.
