Multicenter Study
[Effect of landiolol hydrochloride for intraoperative tachycardia--multicenter questionnaire study].
The purpose of this study was to evaluate effects of landiolol hydrochloride, which is an ultra-short-acting beta-1 selective blocker, for intraoperative tachycardia and to establish practical methods of administration of the drug. ⋯ Information obtained by the questionnaire suggests that bolus injection and/or low-dose continuous administration of landiolol, which are not described in the drug information documents, are effective and safe for treatment of tachycardia during anesthesia.

Comparative Study
[Comparison of the Parker flex-tip tube with the standard tube for Airtraq intubation].
During tracheal intubation with the Airtraq laryngoscope (AL), the tracheal tube tip sometimes impinges on the glottis or other laryngeal structures. We tested a hypothesis that Parker flex-tip tube (PT) makes AL assisted tracheal intubation easier and faster than a conventional tube (Mallinckrod Hi-Lo tube : HT). ⋯ PT significantly reduced the number of impingements. The shape of tube tip and the smaller angle of PT when fitted in AL contributed to the relative ease of tube passage.

We evaluated the effect of repeated transversus abdominis plane (TAP) blocks on postoperative analgesia over the first 48 postoperative hours in the patients undergoing lower abdominal gynecological surgery. ⋯ These findings suggest that bilateral repeated TAP blocks via a placed catheter provide good analgesia without any complications in patients undergoing ovarian cystectomy.

Randomized Controlled Trial Comparative Study
[Comparison of ultrasound-guided and blindly placed radial artery catheterization].
The purpose of this study was to evaluate whether ultrasound (US)-guided radial artery catheterization decreases the number of failed attempts. ⋯ Because the artery and catheter are actually visualized by US, it seems, that US-guided radial artery catheterization is a safe and educational technique.

Randomized Controlled Trial Comparative Study
[Prevention of spinal hypotension associated with cesarean section by aortocaval compression--left 15 degree table tilt vs. uterine displacement by hand].
Women undergoing elective cesarean delivery were randomly assigned to receive a spinal anesthesia in either the semi-lateral (group SL) position or the supine position with uterine displacement (group UD). After spinal injection, group SL patients were turned to a 15 degrees left lateral supine position, and group UD patients had uterine displacement by hand. ⋯ Mean ephedrine requirement was significantly less in the SL group (P < 0.05). Apgar scores did not differ, but umbilical artery pH values were significantly higher in patients of the group SL (P < 0.01).
