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.

Case Reports
[Case of difficult ventilation due to trachea stricture during general anesthesia in a morbidly obese patient].
Obesity has various coexisting illnesses, and the risk of the anesthesia management in an obese patient is high. We report a case of difficult ventilation by trachea stricture during general anesthesia in a morbidly obese patient.

Stiff-person syndrome is an uncommon disease characterized by muscular rigidity and painful spasms in the axial and limb muscles. We report a 58-year-old woman with stiff-person syndrome undergoing thymectomy under general anesthesia. Before surgery, her medications were 25 mg of diazepam, 2 mg of clonazepam, and 15 mg of gabapentin per day. ⋯ After surgery, she was fully awake and TOFR recovered to 100%, but tidal volume was too low to remove the tracheal tube, and mechanical ventilation was continued in ICU. On the next day, the tracheal tube was removed, and she was discharged from ICU. Because anesthetics may delay the recovery of respiratory function in a patient with stiff-person syndrome, careful assessment of respiratory function is needed at the emergence from general anesthesia.

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.

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.
