Randomized Controlled TrialThe usefulness of Smart Pilot View for fast recovery from desflurane general anesthesia.
Smart Pilot View (SPV) (Dräger Medical) provide information about the estimated drug effect of anesthetic drugs. We conducted a prospective randomized trial to evaluated the recovery time in SPV-guided general anesthesia compared with usual practice in patients with desflurane general anesthesia. ⋯ Smart Pilot View guided anesthesia enabled faster recovery from desflurane general anesthesia.

Randomized Controlled TrialIncidence and effects of postoperative migration of interscalene catheter tips placed using ultrasound-guided anterior and posterior approaches.
Continuous interscalene brachial plexus block (CISB) provides analgesia after shoulder surgery. However, even a catheter securely fixed at the insertion site may be susceptible to migration, precluding the block from working consistently. We examined to see if catheter tip migration would occur with no catheter-at-skin change after anterior and posterior approaches to CISB in patients undergoing shoulder surgery, and compared the incidence rate and pain scores between approaches and between catheters with and without tip migration, respectively. ⋯ In patients undergoing shoulder surgery, an interscalene catheter tip can migrate after both anterior and posterior approaches at a similar rate, even if the catheter insertion length is not changed. The tip migration does decrease the analgesic effect of CISB.

Randomized Controlled TrialGeneric rocuronium reduces withdrawal movements compared to original rocuronium under target-controlled infusion induction with propofol.
Rocuronium-induced injection pain often causes withdrawal movements leading to accidental disruption of indwelling needles. Generic rocuronium (Maruishi Pharmaceutical Co., Ltd, Osaka, Japan) with a novel solution has been reported to reduce the injection pain compared to original rocuronium [Esmeron® (Eslax®), MSD Co. Ltd, Tokyo, Japan], however, no reports have compared the injection pain under sedation with propofol, the most frequently used general anesthetic. This study was carried out to compare the injection pain caused by generic rocuronium and that caused by original rocuronium in patients anesthetized by propofol with a target-controlled infusion system. ⋯ Generic rocuronium was considered more suitable than the original rocuronium for induction of anesthesia by propofol performed with a target-controlled infusion system.
