Randomized Controlled Trial Comparative Study Clinical Trial
[Efficacy and safety of 0.1 mg of intrathecal morphine in arthroscopic knee joint surgery].
Intrathecal morphine provides effective postoperative analgesia but is associated with the risk of respiratory depression. A dose of only 0.1 mg has been shown to be optimal for effective and safe pain relief after abdominal surgery. This study was designed to determine whether the addition of 0.1 mg of morphine to the local anesthetic for spinal anesthesia produces adequate analgesia following arthroscopic knee joint surgery. ⋯ Intrathecal administration of 0.1 mg of morphine does not contribute to postoperative analgesia after arthroscopic knee joint surgery.
