ReviewManagement of postoperative nausea and vomiting in women scheduled for breast cancer surgery.
Breast cancer surgery performed under general anesthesia is associated with a high incidence of postoperative nausea and vomiting (PONV). A number of approaches are available for the management of PONV after breast cancer surgery. First, the risk factors related to patient characteristics, surgical procedure, anesthetic technique, and postoperative care can be reduced. ⋯ Unfortunately, the use of glucocorticoids and SR antagonists for preventing PONV is not permitted in Japan according to national health insurance guidelines. Fourth, electro-acupoint stimulation at the P6 point (Nei-Guwan) as a non-pharmacologic therapy is as effective as ondansetron for preventing PONV. Knowledge of the risk factors for PONV, antiemetics, and a non-pharmacologic approach are needed for the management of PONV in women undergoing breast cancer surgery.

Randomized Controlled TrialAmino acid infusions started after development of intraoperative core hypothermia do not affect rewarming but reduce the incidence of postoperative shivering during major abdominal surgery: a randomized trial.
Previous studies have demonstrated that amino acid infusions exert enhanced thermogenic effects during general anesthesia. This study was conducted to investigate whether amino acid infusions started after development of intraoperative core hypothermia can accelerate rewarming. ⋯ Amino acid infusions started after development of intraoperative core hypothermia failed to accelerate rewarming. However, amino acid infusions reduced the incidence of postoperative shivering. Use of amino acid infusions to reduce thermoregulatory vasoconstriction at emergence might contribute to a decrease in the development of postoperative shivering.

Comparison of recovery times from rocuronium-induced muscle relaxation after reversal with three different doses of sugammadex and succinylcholine during electroconvulsive therapy.
This study was conducted to compare recovery times from rocuronium-induced muscle relaxation after reversal with three different doses of sugammadex with succinylcholine during electroconvulsive therapy (ECT). ⋯ This study demonstrates the efficacy of rocuronium-sugammadex as an alternative to SCC for muscle relaxation during ECT, and indicates that 8 mg/kg sugammadex produces equally rapid recovery from rocuronium muscular relaxation compared with spontaneous recovery from 1 mg/kg SCC during ECT.

Randomized Controlled TrialSevoflurane to alleviate pain on propofol injection.
Since the introduction of propofol, several drugs and methods have been used to alleviate the pain on its injection. This study was designed to evaluate the effect of adding sevoflurane 3% during preoxygenation in alleviation of pain on propofol injection. ⋯ The addition of 3% sevoflurane at the time of preoxygenation for 1 min along with routine use of lidocaine-tourniquet completely prevented pain upon propofol injection, whereas sevoflurane by itself provided similar analgesia to premixed lidocaine with propofol.

Comparative StudyComparison of Pentax-AWS Airwayscope video laryngoscope, Airtraq optic laryngoscope, and Macintosh laryngoscope during cardiopulmonary resuscitation under cervical stabilization: a manikin study.
The 2010 American Heart Association or European Resuscitation Council guidelines for cardiopulmonary resuscitation emphasize that rescuers should minimize interruption of chest compressions, even for endotracheal intubation. Cervical stabilization should also be maintained during traumatic cardiac arrest. The utility of the Pentax-AWS Airwayscope (AWS) video laryngoscope and Airtraq (ATQ) optic laryngoscope for airway management has been reported under cervical stabilization. We first evaluated ATQ utility during chest compression with or without cervical stabilization and then compared the AWS, ATQ, and Macintosh laryngoscope (McL) during chest compressions under cervical stabilization in a manikin. ⋯ The AWS was superior to McL and ATQ for endotracheal intubation during simulated cervical stabilization and chest compression.
