Thyroid diseases have an anesthetic implication that includes difficult airway management, uncontrolled hyperthyroidism, hypothyroidism and postthyroidectomy complications. Securing airway: Intubation and extubation both require skillful management and timely decision to reduce morbidity and mortality in the case of large goiter with retrosternal extension that leads to tracheal compression and deviation. We present the anesthetic management in a patient with a large goiter with retrosternal extension leading to tracheal compression and deviation. We managed the case with an awake fiberoptic intubation and guided extubation.

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.

Caudal analgesia is the most commonly used technique providing intra- and postoperative analgesia for various pediatric infraumbilical surgical procedures but with the disadvantage of short duration of action after single injection. Caudal dexamethasone and magnesium could offer significant analgesic benefits. We compared the analgesic effects and side-effects of dexamethasone or magnesium added to caudal ropivacaine in pediatric patients undergoing inguinal hernia repair. ⋯ The addition of dexamethasone or magnesium to caudal ropivacaine significantly prolonged the duration of postoperative analgesia in children undergoing inguinal hernia repair. Also the time to 1(st) analgesic dose was longer and the need for rescue postoperative analgesic was reduced and without increase in incidence of side effects.

The study was undertaken to observe the effect of different maintenance-fluid regimen on intraoperative blood glucose levels in non-diabetic patients undergoing elective major non-cardiac surgery under general anesthesia. ⋯ We conclude that stress induced-hyperglycemic response in patients undergoing major non-cardiac surgery is common in non-diabetic population. Maintenance-fluid therapy by dextrose containing solution as opposed to Ringer's lactate solution increases the incidence of hyperglycemia. To achieve normoglycemia by intravenous bolus dose of human regular insulin, significantly higher doses are required in patients receiving dextrose containing saline as maintenance fluid.

Supine emergence from anesthesia in patients undergoing lumbar surgery in prone position leads to tachycardia, hypertension, coughing, laryngospasm and loss of monitoring as the patients are rolled back to supine position at the end of surgery. The prone extubation might facilitate a smoother emergence because the patients are not disturbed during emergence and secretions are drained away from patient's airway. ⋯ In healthy normotensive patients, emergence from anesthesia in the prone position is associated with minimal hemodynamic change, and fewer incidences of coughing, laryngospasm, and monitor disconnections.
