Randomized Controlled TrialHemispheric synchronized sounds and perioperative analgesic requirements.
Data on the effect of Hemisync sounds on perioperative analgesic requirements are scant. ⋯ The use of Hemisync sounds before and during general anesthesia reduces intraoperative analgesic requirements, postoperative pain scores, and discharge time.

Randomized Controlled TrialA randomized, double-blind, placebo-controlled trial of epidural morphine analgesia after vaginal delivery.
Pain after vaginal delivery can interfere with the activities of daily living. We hypothesized that epidural medication administered after delivery would be of benefit for acute postpartum pain management. The objective of this study was to assess whether epidural morphine after vaginal delivery would reduce the analgesic requirements for perineal pain. ⋯ There was a 78% reduction in analgesic requirements in women given epidural morphine after vaginal delivery compared with placebo for both primiparous and multiparous patients. Women who receive epidural labor analgesia for vaginal deliveries and stay in the hospital for 24 h after delivery may benefit from postpartum administration of epidural morphine.

Randomized Controlled TrialThe GlideScope facilitates nasogastric tube insertion: a randomized clinical trial.
The GlideScope (Saturn Biomedical Systems, B.C., Canada) is a reusable videolaryngoscope and is considered an effective device for tracheal intubation. We designed this study to evaluate the application of this device in nasogastric tube (NGT) insertion. ⋯ GlideScope facilitates NGT insertion and reduces the duration of the procedure.

Up-down determination of the 90% effective dose of phenylephrine for the treatment of spinal anesthesia-induced hypotension in parturients undergoing cesarean delivery.
Hypotension frequently complicates spinal anesthesia for cesarean delivery, and vasopressors are the mainstay for treatment. The most effective dose of phenylephrine for the treatment of spinal anesthesia-induced hypotension has not been estimated. ⋯ In this study, we estimated that the ED(90) of phenylephrine required to treat spinal anesthesia-induced hypotension in cesarean delivery is approximately 150 microg.

Magnetic resonance imaging findings after uneventful continuous infusion neuraxial analgesia: a prospective study to determine whether epidural infusion produces pathologic magnetic resonance imaging findings.
Magnetic resonance imaging (MRI) is considered the preferred diagnostic tool to determine whether postepidural neurologic symptoms are due to hematoma or abscess. However, there is currently no published information regarding the normal appearance of a MRI after a continuous epidural infusion. In this prospective cohort study, we defined the characteristic appearance of MRI findings after uneventful epidural analgesia. ⋯ The lack of significant collections or mass effects seen in the MRIs of our patients after continuous infusion of epidural analgesia suggests that the presence of these findings in a patient with new neurologic symptoms after administration of epidural analgesia should be considered pathologic and warrant immediate attention.
