Postoperative pain is the primary reason for prolonged hospital stay after laparoscopic cholecystectomy. This study compared the effect of a single oral preoperative administration of paracetamol (1 g) with 2 different doses of pregabalin (150 or 300 mg) for attenuating postoperative pain and analgesic consumption. ⋯ The single oral preoperative dose administration of pregabalin had significant opioid-sparing effect in the first 6 h after surgery, whereas side effects were more common with administration of pregabalin 300 mg.

Analgesia in patients with fracture shaft femur is usually insufficient as physician usually relies on parental analgesia in such situations. Local anesthetic blockade of femoral nerve to provide analgesia in fracture shaft femur is an under-used technique. We conducted a study to evaluate the efficacy of femoral nerve block (FNB) with 0.5% ropivacaine for acute pain relief in patients with fracture shaft femur. ⋯ It was concluded that in the emergency ward, rapid, effective, and long lasting analgesia can be achieved by safe and simple FNB in patients with fracture shaft femur.

Etomidate is an intravenous anesthetic agent released for clinical use in the United States in 1972. Its popularity in clinical practice is the result of its beneficial effects on intracerebral dynamics with limited effects on hemodynamic function. ⋯ However, recent concern has been expressed regarding its effects on the endogenous production of corticosteroids and the impact of that effect on patient outcomes. The following manuscript reviews clinical reports regarding etomidate use in the pediatric population and discusses recent concerns regarding its effects on corticosteroid metabolism and the implications of such effects for clinical use.

Endotracheal intubation is essential during general anesthesia and muscle relaxant drugs provide ideal conditions for this purpose. The objective of this study was to evaluate the intubating condition of remifentanil combined with propofol without muscle relaxant. ⋯ In premedicated children, propofol-remifentanil combination provides adequate conditions for tracheal intubation that is comparable with succinylcholine. Hemodynamic response to laryngoscopy and tracheal intubation was controlled better in group R.

Elderly patients are susceptible to post-induction hypotension. Volume loading and vasopressors for prevention of hypotension in elderly patients may increase perioperative cardiovascular risks. Ondansetron by blocking Bezold-Jarisch reflex (BJR) through inhibition of serotonin receptors has been effective in the prevention of post-spinal hypotension, and bradycardia. Bradycardia frequently accompanies post-induction hypotension in elderly patients, which signifies a possible preventing role for ondansetron. No previous study has evaluated the prophylactic effects of ondansetron for the prevention of post-induction hypotension. ⋯ The results of this study show the effectiveness of intravenous ondansetron for prevention of post-induction hypotension in elderly patients. The mechanism of this effect largely is unknown. Role of ondansetron for prevention of post-induction hypotension may not fully understandable by its interaction with BJR, as has been shown in post-spinal hypotension.
