Randomized Controlled Trial Comparative Study
[Technical advantages of ultrasound-guided obturator nerve block compared with the nerve stimulating technique].
We investigated the onset time of obturator nerve block and time required for the nerve block comparing two groups in a prospective randomized study. ⋯ Ultrasound imaging facilitated the identification of obturator nerves between adductor muscles. Ultrasound-guided obturator nerve block is a safe, quick and useful technique.

Randomized Controlled Trial Comparative Study
[Effects of intravenous vasopressor on spread of spinal anesthesia with 0.5% hyperbaric bupivacaine for caesarean delivery].
It is known that when isobaric bupivacaine is applied for Caesarean delivery, phenylephrine is superior to ephedrine in preventing rostral spread of spinal anesthesia. In this study, we prospectively investigated whether phenylephrine can prevent rostral spread of spinal hyperbaric bupivacaine. ⋯ 1. Phenylephrine prevented rostral spread of spinal hyperbaric bupivacaine. 2. Haemodynamic changes were significantly different between the two groups. 3. Umbilical artery pH was significantly higher with phenylephrine than with ephedrine.

Randomized Controlled Trial
[Efficacy of bougie in difficult intubation with the Airway Scope caused by inability to lift the epiglottis directly].
There are some disadvantages of the Airway Scope (AWS), and the most crucial one is that the AWS has only one fixed-size AWS blade. When the blade is too short to reach beneath the epiglottis and to lift it directly, an endotracheal tube hits the epiglottis and cannot be advanced into the glottic aperture even when it is visible. A bougie may solve this difficulty because its angulated tip can be controlled in a desired direction. Therefore, we examined the efficacy of the bougie on this problem. ⋯ Use of the bougie was useful for difficult intubation with the AWS caused by inability to lift the epiglottis directly.

Randomized Controlled Trial
[Optimum intubating dose of rocuronium for short duration surgery in adult patients].
The aim of this study was to examine optimum intubating dose of rocuronium in adult patients who had been scheduled for short duration surgery. ⋯ For short duration surgeries, rocuronium 0.5 mg x kg(-1) was appropriate to perform safe tracheal intubation and minimize duration of action of rocuronium.

Randomized Controlled Trial Comparative Study
[Effects of intravenous midazolam, fentanyl or ketamine on pain relief during performance of epidural anesthesia].
Performing epidural anesthesia is accompanied by pain. The aim of this study is to examine whether intravenous administration of a sedative, an opioid, or an anesthetic eliminates pain score during the epidural procedure. ⋯ The findings obtained from this study suggest that the analgesic action of the drug is not essential to the pain relief and the anxiolytic action is important for the epidural procedure.
