Nonsteroidal anti-inflammatory drugs used for postoperative analgesia have considerable adverse effects, with paracetamol having a different mechanism of action, superior side effect profile and availability in intravenous (IV) form, this study was conducted to compare intra-peritoneal bupivacaine with IV paracetamol for postoperative analgesia following laparoscopic cholecystectomy. ⋯ Although local anesthetic infiltration and intra-peritoneal administration of 0.5% bupivacaine decreases the severity of incisional, visceral and shoulder pain in the early postoperative period, IV paracetamol provides sustained pain relief for 24 postoperative hours after elective laparoscopic cholecystectomy.

The aim of the study was to compare postoperative pain relief in patients undergoing an elective thoracotomy with thoracic epidural analgesia using single shot magnesium and clonidine as adjuvants to bupivacaine. ⋯ Thoracic epidural analgesia using bupivacaine with clonidine is an efficient therapeutic modality for postthoracotomy pain. Magnesium as an adjuvant provided quality postoperative analgesia decreasing the need for postoperative rescue analgesia and incidence of postoperative shivering without causing sedation.

Intrathecal neostigmine and magnesium sulfate (MgSO4) produce substantial antinociception, potentiate analgesia of bupivacaine without neurotoxicity. ⋯ Intrathecal Neostigmine and MgSo4 does not affect characteristics of SA. Postoperative analgesia of neostigmine was better than MgSO4. Neostigmine provides some protection against hypotension of SA whereas MgSO4 protects against bradycardia.

Many adjuvants are used to increase the efficacy of epidural local anesthetics for postoperative analgesia. ⋯ Epidural morphine plus bupivacaine has a longer duration of analgesia and greater hemodynamic stability as compared to epidural clonidine plus bupivacaine for postoperative analgesia in abdominal surgeries.

Case Reports
Epidural catheter misplaced into the thoracic cavity: Utilized to provide interpleural analgesia.
Thoracic epidural analgesia is one of the most effective and time-tested modalities of providing postthoracotomy pain relief. It improves postoperative pulmonary outcome. Nevertheless, being a blind procedure several complications have been associated with the technique. ⋯ We have discussed a patient who underwent a right thoracotomy for excision of emphysematous bulla of lung under general anesthesia with thoracic epidural. The epidural catheter was misplaced in the pleural cavity and was detected intraoperatively after thoracotomy. The catheter was left in situ and was successfully utilized to provide postoperative analgesia via the interpleural route.
