Postoperative nausea and vomiting is commonly associated with adverse consequences and hamper the postoperative recovery in spite of the availability of many antiemetic drugs and regimens for its prevention. The study was aimed to compare the prophylactic effects of intravenously administered palonosetron, ondansetron, and granisetron on prevention of postoperative nausea and vomiting after general anesthesia. ⋯ Palonosetron was comparatively highly effective to prevent the PONV after anesthesia due to its prolonged duration of action than ondansetron and granisetron.

A well-secured endotracheal tube (ETT) is essential for safe anesthesia. The ETT has to be fixed with the adhesive plasters or with tie along with adhesive plasters appropriately. It is specially required in patients having beard, in intensive care unit (ICU) patients or in oral surgeries. ⋯ We report an incidence where the ETT cuff tubing was severed while attempting to re-adjust and re-fix the ETT and the patient required re-intubation. Retrospectively, we thought of and describe a safe, reliable and novel technique to prevent cuff deflation of the severed inflation tube. The technique can also be used to monitor cuff pressure in such scenarios.

Hypothermia is a frequent observation in elderly males undergoing transurethral resection of prostate (TURP) under spinal anesthesia. The use of irrigating fluids at room temperature results in a decrease body temperature. Warmed irrigating solutions have shown to reduce heat loss and the resultant shivering. Such investigation was not much tried in low resource settings. ⋯ Use of warm irrigation fluid during TURP reduces the risk of perioperative hypothermia and shivering.

A double-blinded randomized controlled study to compare discharge time and patient satisfaction between two groups of patients submitted to open surgeries for abdominal malignancies using segmental thoracic spinal or general anesthesia. ⋯ This preliminary study has shown that segmental thoracic spinal anesthesia can be used successfully and effectively for open surgeries for abdominal malignancies by experienced anesthetists. It showed shorter postanesthesia care unit stay, better postoperative pain relief and patient satisfaction than general anesthesia.

Mixing of various adjuvants has been tried with local anesthetics in an attempt to prolong anesthesia from peripheral nerve blocks but have met with inconclusive success. More recent studies indicate that 8 mg dexamethasone added to perineural local anesthetic injections augment the duration of peripheral nerve block analgesia. ⋯ Addition of dexamethasone (8 mg) to ropivacaine in supraclavicular brachial plexus approach significantly and safely prolongs motor blockade and postoperative analgesia (sensory) that lasted much longer than that produced by local anesthetic alone.
