Review Meta Analysis
Cerebral near-infrared spectroscopy in adult heart surgery: systematic review of its clinical efficacy.
This systematic review is aimed at answering the following questions: 1) Is near-infrared spectroscopy (NIRS) clinically effective in detecting cerebral desaturation during heart surgery? 2) Are these results based on studies with solid methodology? ⋯ The clinical application of NIRS in heart surgery as a brain-monitoring device seems interesting. However, NIRS has to be investigated more rigorously to prove its clinical utility in cardiac surgery.

Randomized Controlled Trial Clinical Trial
The "BURP" maneuver worsens the glottic view when applied in combination with cricoid pressure.
The purpose of this study was to determine if the application of a BURP maneuver to the cricoid cartilage would combine the benefits of both the BURP and the Sellick maneuvers, resulting in an improved glottic view and offer the potential of protection against passive gastric regurgitation. ⋯ There is no benefit to routinely applying a modified "BURP" maneuver to the cricoid cartilage during rapid sequence induction of anesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Vital capacity and patient controlled sevoflurane inhalation result in similar induction characteristics.
To compare patient controlled inhalational induction (PCI) with the most commonly used sevoflurane induction technique, vital capacity inhalational induction (VCI). ⋯ PCI was comparable to VCI in sevoflurane induction with respect to the speed of induction, side effects during induction and patient satisfaction. However, PCI requires no special training and is widely applicable to all patient populations.

Randomized Controlled Trial Comparative Study Clinical Trial
Xenon does not reduce opioid requirement for orthopedic surgery.
Is to test the hypothesis that 70% xenon has a relevant opioid sparing effect compared to a minimum alveolar concentration (MAC)-equivalent combination of N(2)O and desflurane. ⋯ Xenon compared to a MAC-equivalent combination of N(2)O and desflurane does not substantially reduce opioid requirement for orthopedic surgery. A small but clinically irrelevant difference cannot be excluded, however.

Randomized Controlled Trial Clinical Trial
Nerve stimulator guided pudendal nerve block decreases posthemorrhoidectomy pain.
Based on our institution's initial results that reflected reduced postoperative pain using a modified pudendal nerve block technique, we conducted a prospective, randomized, double-blind study to investigate whether a combination of general anesthesia and bilateral nerve stimulator guided pudendal nerve blocks could provide better postoperative pain relief compared to general anesthesia alone or in combination with placebo nerve blocks. ⋯ A combination of general anesthesia and nerve stimulator guided pudendal nerve block showed significantly reduced postoperative pain, shortened hospital stay, and earlier return to normal activity. Thus, this technique deserves more widespread use in patients undergoing hemorrhoidectomy.
