Laparoscopic cholecystectomy is performed to minimize the postoperative morbidity and early return to work. This study was planned to evaluate the efficacy and feasibility of thoracic epidural anesthesia for laparoscopic cholecystectomy, so that it can be later used as anesthetic technique in patients when general anesthesia is not feasible. ⋯ The thoracic epidural anesthesia with 0.75% ropivacaine and fentanyl for elective laparoscopic cholecystectomy is efficacious and has preserved ventilation and hemodynamic changes within physiological limits during pneumoperitoneum with minimal treatable side effects.

Analgesia is based on balanced anaesthesia, which is usually maintained by administration of narcotic agents. In some patients, it is not possible to use narcotics. We compared hemodynamic changes, anaesthesia depth, emetic sequelae and post-operative pain between sodium Diclofenac, Ketamine-Propofol (DKP) and Fentanyl-Midazolam (FM). ⋯ This study revealed that intravenous administration of Sodium Diclofenac along with Ketamine and Propofolplus N2O 50% for general anaesthesia provides a balanced anaesthesia as well as hemodynamic stability, and adequate depth of anaesthesia. It also reduces the postoperative pain and need for narcotics. We recommended DKP plus N2O 50% method for patients prohibited from opioid administration. It will be an acceptable method in sensitive patients.

Tonsillectomy is the most commonly performed surgical procedure in ENT practice. Postoperative pain remains the major problem following tonsillectomy, if not treated. Different methods and many drugs have been used to control the postoperative pain. In this study, we evaluate the role of gabapentin premedication vs paracetamol in management of postoperative pain following adenotonsillectomy in children. ⋯ Gabapentin premedication improves postoperative analgesia following adenotonsillectomy in children and reduce analgesic requirements in comparison with paracetamol premedication, with no reported side effects.

Amniotic fluid embolism (AFE) is a rare obstetric catastrophe with an incidence of 7.7 per 100 000 deliveries and mortality as high as 60% to 80%. We describe a case of perioperative cardiac arrest in a young parturient undergoing an emergent cesarean section. ⋯ Her autopsy revealed edematous lungs with amniotic fluid debris within pulmonary vessels thus establishing the diagnosis of AFE. Amniotic fluid embolism is life threatening and difficult to predict or prevent condition, which should be always be kept in mind in a parturient with sudden cardiovascular collapse, so that resuscitation commences immediately, as early intervention is essential for a positive outcome.

Postoperative nausea and vomiting (PONV) is a serious concern in patients undergoing laparoscopic cholecystectomy (LC), with an incidence of 46 to 72%. The purpose of this study was to compare the antiemetic efficacy of intravenous (iv) ondansetron 8 mg, ramosetron 0.3 mg, and palonosetron 0.075 mg for prophylaxis of PONV in high-risk patients undergoing LC. ⋯ Ramosetron 0.3 mg iv was more effective than palonosetron 0.075 mg and ondansetron 8 mg in the early postoperative period, but there was no significant difference in the overall incidence of nausea suffered.
