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.

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.

Case Reports
[Combined Use of a Videolaryngoscope and a Transilluminating Device for Intubation with Two Difficult Airways].
Videolaryngoscope is useful in patients with difficult airways, but it may not be in some patients. We report the use of a lighted stylet to facilitate tracheal intubation in 2 patients in whom laryngoscopy with a videolaryngoscope was difficult. Case 1: A 52-year-old female with loose teeth and lockjaw presented for a scoliosis surgery under general anesthesia. ⋯ Combined use of the Trachilight™ with the GVL, facilitated tracheal intubation. The Trachilight™ is a recognized aid to facilitate trachal intubation but the device is now commercially not available. Neverthless, we believe that a lighted stylet is potentially useful for tracheal intubation when the view of the glottis with a videolaryngoscopy is not ideal.

The McGRATH® MAC videolaryngoscope (McG) is a new device for tracheal intubation. Its utility has been reported in both tracheal intubation in children and difficult tracheal intubation for adults. Initially, the blade introduced was for adult use only, but the one for children was also in the market. We examined the usefulness of the McG for tracheal intubation in 100 children. ⋯ McG is useful in both routine and difficult airway management for children.

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).
