The effect of pregabalin on preoperative anxiety and sedation levels: a dose-ranging study.

Background: Pregabalin is a gabapentinoid compound, which has been alleged to possess anxiolytic, analgesic, and anticonvulsant properties. We hypothesized that premedication with oral pregabalin would produce dose-related reductions in acute (state) anxiety and increases in sedation (sleepiness) before induction of general anesthesia. A secondary objective was to determine if premedication with pregabalin would reduce postoperative pain.

The effect of residual neuromuscular blockade on the speed of reversal with sugammadex.

Background: Sugammadex is a modified gamma cyclodextrin compound which encapsulates rocuronium resulting in rapid reversal of residual neuromuscular blockade. We performed a post hoc analysis of data from a multicenter study designed to mimic standard clinical practice which would test the hypothesis that the presence (versus the absence) of a twitch response to neuromuscular stimulation at the time of reversal drug administration would influence the speed and completeness of the reversal effect of sugammadex.

Methods: One-hundred-seventy-one consenting patients undergoing general anesthesia with a volatile-based anesthetic technique were enrolled in a multicenter observational study.

Dexmedetomidine infusion during laparoscopic bariatric surgery: the effect on recovery outcome variables.

Background: Dexmedetomidine (Dex), an alpha(2) agonist, has well-known anesthetic and analgesic-sparing effects. We designed this prospective, randomized, double-blind, and placebo-controlled dose-ranging study to evaluate the effect of Dex on both early and late recovery after laparoscopic bariatric surgery.

Methods: Eighty consenting ASA II-III morbidly obese patients were randomly assigned to 1 of 4 treatment groups: (1) control group received a saline infusion during surgery, (2) Dex 0.

Effect of short-term postoperative celecoxib administration on patient outcome after outpatient laparoscopic surgery.

Purpose: Non-opioid analgesics are increasingly used as part of a multimodal regimen for pain management. This prospective, randomized, double-blinded, placebo-controlled study was designed to evaluate the effect of short-term postoperative administration of celecoxib on pain management and recovery outcomes following laparoscopic surgery.

Methods: Eighty consenting ASA I-III outpatients undergoing laparoscopic surgery were randomly assigned to one of two treatment groups: Control (placebo) or Celecoxib (celecoxib, 400 mg x day(-1)).

Sugammadex reversal of rocuronium-induced neuromuscular blockade: a comparison with neostigmine-glycopyrrolate and edrophonium-atropine.

Background: Sugammadex is a modified [gamma] cyclodextrin compound, which encapsulates rocuronium to provide for a rapid reversal of residual neuromuscular blockade. We tested the hypothesis that sugammadex would provide for a more rapid reversal of a moderately profound residual rocuronium-induced blockade than the commonly used cholinesterase inhibitors, edrophonium and neostigmine.

Methods: Sixty patients undergoing elective surgery procedures with a standardized desflurane-remifentanil-rocuronium anesthetic technique received either sugammadex, 4 mg/kg IV (n = 20), edrophonium, 1 mg/kg IV and atropine, 10 microg/kg IV (n = 20), or neostigmine, 70 microg/kg IV and glycopyrrolate, 14 microg/kg IV (n = 20) for reversal of neuromuscular blockade at 15 min or longer after the last dose of rocuronium using acceleromyography to record the train-of-four (TOF) responses.

Anesthesia management with short acting agents for bilateral pheochromocytoma removal in a 12-year-old boy.

A 12-year-old boy with bilateral adrenal pheochromocytoma pretreated with furosemide, nifedipine, prazosin, and propranolol underwent surgical removal of the tumors. General anesthesia with desflurane, remifentanil infusion and thoracic epidural analgesia was performed. To control the blood pressure (BP), remifentanil up to 1 microg.
