Review Meta AnalysisThe prevention of chronic postsurgical pain using gabapentin and pregabalin: a combined systematic review and meta-analysis.
Many clinical trials have demonstrated the effectiveness of gabapentin and pregabalin administration in the perioperative period as an adjunct to reduce acute postoperative pain. However, very few clinical trials have examined the use of gabapentin and pregabalin for the prevention of chronic postsurgical pain (CPSP). We (1) systematically reviewed the published literature pertaining to the prevention of CPSP (≥ 2 months after surgery) after perioperative administration of gabapentin and pregabalin and (2) performed a meta-analysis using studies that report sufficient data. A search of electronic databases (Medline, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, IPA, and CINAHL) for relevant English-language trials to June 2011 was conducted. ⋯ The present review supports the view that perioperative administration of gabapentin and pregabalin are effective in reducing the incidence of CPSP. Better-designed and appropriately powered clinical trials are needed to confirm these early findings.

Randomized Controlled Trial Comparative StudyPostoperative analgesic and behavioral effects of intranasal fentanyl, intravenous morphine, and intramuscular morphine in pediatric patients undergoing bilateral myringotomy and placement of ventilating tubes.
Bilateral myringotomy and placement of ventilating tubes (BMT) is one of the most common pediatric surgical procedures in the United States. Many children who undergo BMT develop behavioral changes in the postanesthesia care unit (PACU) and require rescue pain medication. The incidence of these changes is lower in children receiving intraoperative opioids by the nasal, IM, or IV route compared with placebo. However, there are no data to indicate which route of administration is better. Our study was designed to compare the immediate postoperative analgesic and behavioral effects of 3 frequently used intraoperative techniques of postoperative pain control for patients undergoing BMT under general anesthesia. ⋯ In this double-blind, double-dummy study, there was no difference in the efficacy of intranasal fentanyl, IM and IV morphine in controlling postoperative pain and emergence delirium in children undergoing BMT placement. The IM route is the simplest and avoids the potential for delays to establish vascular access for IV therapy and the risks of laryngospasm if intranasal drugs pass through the posterior nasopharynx and irritate the vocal cords.

ReviewReview of the off-label use of recombinant activated factor VII in pediatric cardiac surgery patients.
In recent years the off-label use of recombinant activated factor VII (rFVIIa) has markedly increased, particularly in pediatric cardiac surgery patients, and practitioners differ widely in their usage of the drug. In 2009, the Congenital Cardiac Anesthesia Society (CCAS) assembled a task force to review the literature on rFVIIa administration to pediatric cardiac surgery patients. The goal of the CCAS Task Force was to assess current practices and make recommendations about rFVIIa therapy to enhance quality of care, improve patient outcomes, reduce costs, and develop future research. ⋯ There are insufficient data to make evidence-based recommendations. Randomized controlled trials are needed to assess the efficacy of rFVIIa as prophylactic, routine, or rescue therapy and to determine the drug's safety profile particularly with regard to thrombosis. The CCAS rFVIIa Task Force will continue to monitor the literature, gather data, and make updates as more information becomes available.
