Pretreatment with nitrous oxide enhances induction of anesthesia with sevoflurane: A randomized controlled trial.
Inhalation anesthesia with sevoflurane may be enhanced by several drugs or techniques. The aim of the present study was to investigate the effect of nitrous oxide (N2O) pretreatment on the speed of anesthesia induction with sevoflurane. ⋯ Our results show that pretreatment of the patients with 50% N2O for 10 min enhances the speed of induction with sevoflurane as assessed by the BIS monitoring.

Prevention of hypotension associated with the induction dose of propofol: A randomized controlled trial comparing equipotent doses of phenylephrine and ephedrine.
Propofol, the most commonly used intravenous (IV) anesthetic agent is associated with hypotension on induction of anesthesia. Different methods have been used to prevent hypotension but with variable results. The objective of this study was to evaluate efficacy of equipotent doses of phenylpehrine and ephedrine in preventing the hypotensive response to the induction dose of propofol. ⋯ In equipotent doses, phenylephrine is as good as ephedrine in preventing the hypotensive response to an induction dose of propofol.

Effect of buprenorphine as an adjunct with plain local anesthetic solution in supraclavicular brachial plexus block on quality and duration of postoperative analgesia.
Supraclavicular brachial plexus block is ideal for upper limb surgical procedures. Buprenorphine, an agonist antagonist opioid has been used as an adjunct to prolong analgesia. We aimed to evaluate the quality and duration of postoperative analgesia by addition of buprenorphine to local anesthetic solution. ⋯ Addition of 3 μg/kg buprenorphine to 0.5% bupivacaine for supraclavicular brachial plexus block prolonged duration of postoperative analgesia and sensory blockade without an increase in side effects.

Hyperbaric spinal ropivacaine in lower limb and hip surgery: A comparison with hyperbaric bupivacaine.
Bupivacaine is more cardiotoxic than ropivacaine. Ropivacaine provides effective spinal anesthesia for lower limb and hip surgeries. This prospective study was designed to compare the efficacy and safety of intrathecal hyperbaric ropivacaine with hyperbaric bupivacaine for patients undergoing limb and hip surgeries. ⋯ We conclude that hyperbaric bupivacaine used intrathecally has a faster onset of sensory block and prolonged duration of analgesia compared to hyperbaric ropivacaine.

ReviewSmall is the new big: An overview of newer supraglottic airways for children.
Almost all supraglottic airways (SGAs) are now available in pediatric sizes. The availability of these smaller sizes, especially in the last five years has brought a marked change in the whole approach to airway management in children. SGAs are now used for laparoscopic surgeries, head and neck surgeries, remote anesthesia; and for ventilation during resuscitation. ⋯ Despite this expanded usage, there remains little evidence to support its usage in prolonged surgeries and in the intensive care unit. This article presents an overview of the current options available, suitability of one over the other and reviews the published data relating to each device. In this review, the author also addresses some of the general concerns regarding the use of SGAs and explores newer roles of their use in children.
