Randomized Controlled Trial Comparative Study
[Efficacy of Ultrasound-guided Thoracic Paravertebral Block Compared with the Epidural Analgesia in Patients Undergoing Video-assisted Thoracoscopic Surgery].
Thoracic paravertebral block (TPVB) has proven to be safer by using ultrasound imaging. This prospective randomized study was designed to investigate postoperative pain relief and intraoperative hemodynamics in patients undergoing ultrasound-guided TPVB or epidural analgesia. ⋯ Ultrasound guided TPVB was performed affecting hemodynamics less than the epidural anesthetic. There was less postoperative analgesic effect on TPBV than on epidural analgesia after thora- coscopic surgery when continuously infusing 0.2% ropivacaine 6 ml · hr(-1).

Randomized Controlled Trial
[McGRATH® MAC Is Useful to Learn Tracheal Intubation Using a Macintosh Laryngoscope].
Learning tracheal intubation using a Macintosh laryngoscope (McL) is important although video laryngoscope is becoming popular. The purpose of this study was to compare the usefulness as a training device for intubation technique using McL with three devices; McGRATH® MAC (MAC), Airwayscope® (AWS) and McL. ⋯ The McGRATH® MAC may possess advantages compared to Airwayscope® and Macintosh laryngoscope as a training device for learning intubation technique using Macintosh laryngoscope and understanding anatomy of the larynx.

Randomized Controlled Trial Comparative Study
[Comparison of Analgesic Efficacy between Posterior and Lateral Transversus Abdominis Plane Block Techniques for Laparoscopic Gynecological Surgery].
Posterior transversus abdominis plane (TAP) block has been considered as a useful technique for lower abdominal postoperative analgesia, but in ultrasound-guided block, its efficacy and usability are still unknown. We prospectively compared the analgesic efficacy among posterior and lateral TAP block and with control group in laparoscopic gynecological surgery. ⋯ Ultrasound-guided posterior TAP block could become a more useful tool for postoperative analgesia. We presumed that its additional effect is caused from reduction of visceral pain related to sympathetic nerve block.
