Review Meta AnalysisBeta-adrenergic antagonists during general anesthesia reduced postoperative pain: a systematic review and a meta-analysis of randomized controlled trials.
We have performed a systematic literature review and a meta-analysis investigating the effect of beta-adrenergic antagonist on perioperative pain in randomized clinical trials (RCTs). The search included the CENTRAL, CINAHL, EMBASE, and MEDLINE databases (from inception to 10 February 2015). From the retrieved full texts, we hand-searched the references and PubMed related citations. ⋯ However, in two opioid-controlled studies, one in knee arthroscopy and another in tubal ligation patients, the proportion of patients needing rescue analgesia was two-times higher in esmolol-treated patients: 52-57 vs. 23-34%, p < 0.05. Adverse effects were rarely reported, and as reported were mostly cardiovascular alterations. In conclusion, intra-operative beta-adrenergic antagonists' administration may decrease postoperative pain and analgesic consumption when given as an adjuvant to general anesthesia.

Randomized Controlled Trial Comparative StudyEffect of glycopyrrolate versus atropine coadministered with neostigmine for reversal of rocuronium on postoperative catheter-related bladder discomfort in patients undergoing transurethral resection of bladder tumor: a prospective randomized study.
Muscarinic receptors are involved in the mechanism of postoperative catheter-related bladder discomfort (CRBD). Glycopyrrolate and atropine as adjuncts to reversal of neuromuscular blockers have differential inhibitory effects on muscarinic receptors. This study was conducted to compare the effect of glycopyrrolate versus atropine on postoperative CRBD in patients undergoing transurethral resection of a bladder tumor (TURBT). ⋯ Glycopyrrolate as an adjunct to reversal of neuromuscular blockers decreased the incidence of early postoperative CRBD and postoperative tramadol requirements in patients undergoing TURBT when compared to atropine.

Randomized Controlled Trial Comparative StudyThe effects of intravenous fosaprepitant and ondansetron in the prevention of postoperative nausea and vomiting in patients who underwent lower limb surgery: a prospective, randomized, double-blind study.
Postoperative nausea and vomiting (PONV) is the most common complication after surgery, and opioid administration increases its incidence. We compared the preventive effects of fosaprepitant, a neurokinin-1 (NK1) receptor antagonist, with those of ondansetron on PONV in patients who underwent lower limb surgery with postoperative epidural opioid administration. ⋯ Fosaprepitant was more effective than ondansetron in decreasing the incidence of vomiting after lower limb surgery with postoperative opioid administration. Meanwhile, fosaprepitant was not inferior to ondansetron in decreasing the incidence and severity of PONV.

Randomized Controlled Trial Comparative StudyEvaluation of the efficacy of six supraglottic devices for airway management in dark conditions: a crossover randomized simulation trial.
During out-of-hospital cardiopulmonary resuscitation, several factors can render tracheal intubation more difficult, such as when rescuers must secure the airway in complete darkness or with limited illumination. The purpose of this study was to evaluate the efficacy of six supraglottic devices (SGDs), ProSeal(®) (ProSeal), Classic(®) (Classic), Supreme(®) (Supreme), Laryngeal Tube(®) (LT), air-Q(®) (air-Q), and i-gel(®) (i-gel), for airway management under light and dark conditions using a manikin. ⋯ Compared to ProSeal and Classic, Supreme, i-gel, LT, and air-Q are more effective for airway management in the dark. Our findings suggest that anatomically shaped SGDs may help novice doctors secure the airway under dark conditions.

ReviewAnesthetic management of pediatric patients with Sturge-Weber syndrome: our experience and a review of the literature.
Sturge-Weber syndrome (SWS) is a rare sporadic congenital neurocutaneous syndrome which is characterized by vascular malformation involving the brain, face and eye. The anesthetic management is complicated by its localized as well as systemic manifestations, associated anomalies and difficult airway due to the presence of angiomas of the oral cavity and airway. We retrospective analyzed the perioperative anesthetic management of children with SWS undergoing ophthalmic surgery and reviewed the literature. ⋯ Preoperative evaluation with airway assessment should be performed with the knowledge of local and systemic manifestation of the syndrome. Proconvulsant and anticonvulsant properties of the anesthetics, as well as drug interactions of antiepileptic medications should be considered when planning anesthesia. Avoiding a rise in intracranial and intraocular pressures, vigilant intraoperative monitoring and postoperative care are the key for conducting safe anesthesia in these children. For ophthalmic procedures, LMAs can be used for airway maintenance with minimal complications in children with SWS.
