Comparison of low-dose ketamine to methadone for postoperative pain in opioid addicts: a randomized clinical trial.

Background: Postoperative pain can lead to several complications. The effectiveness of different opioids in relieving pain after surgery has been widely studied. However, managing pain in patients with opioid addiction is still challenging.

A Survey on the Short-term Outcome of Microlumbar Discectomy with General versus Spinal Anesthesia.

Background: Surgery on the lower thoracic and lumbosacral spine is possible with both general and spinal anesthesia, but most spine surgeons are reluctant to perform the surgery with spinal anesthesia. We aimed to conduct a survey on the short-term outcome of microlumbar discectomy in the patients who had been treated under general or spinal anesthesia.

Methods: In this prospective study, we performed a survey on 72 patients who underwent microlumbar discectomy under general anesthesia (group A) or spinal anesthesia (group B).

The Analgesic Efficacy of Intrathecal Bupivacaine and Fentanyl with Added Neostigmine or Magnesium Sulphate.

Background: An appropriate anesthesia duration with minimal side effects and prolonged postoperative analgesia are the ideal characteristics of an intrathecal drug used during spinal anesthesia. Neostigmine and magnesium sulphate have been used as spinal anesthetic additives with narcotics and local anesthetics.

Objectives: This study aimed to assess the analgesic properties of intrathecal neostigmine and magnesium sulphate by adding them to intrathecal bupivacaine-fentanyl.
