Anesthesia, essays and researches
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.
Anesthetists used lower doses of fentanyl, successfully with hemodynamic control by titrating volatile anesthetic agents or vasodilators for fast-tracking in cardiac surgery. ⋯ The I-gel airway is well-tolerated by adult patients undergoing cardiac surgery, and requires lower total doses of anesthetics than endotracheal intubation with hemodynamic control and helps in fast-tracking.
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.
