The risk factors for postoperative myasthenic crisis (MC) in patients with myasthenia gravis (MG) receiving preoperative corticosteroids were unknown. ⋯ Based on this study, we concluded that the existence of preoperative bulbar symptoms seems to be a predictor for the development of postoperative-MC in patients with MG undergoing a transsternal thymectomy.

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).

In surgical graft replacement of the descending aorta graft, one-lung ventilation (OLV) is required to provide adequate surgical view and to allow removal of blood from the left lung. It is best to use a double-lumen tube (DLT) to assure OLV but it is sometimes difficult to place the left-sided DLT due to thoracic aneurysm or the dissection lumen. We retrospectively investigated tracheobronchial anatomy by chest X-ray and chest computed tomography (CT) in 29 cases of descending aorta replacement to determine how best to manage difficult placement of the left-sided DLT. ⋯ We experienced difficulty in placement of the left-sided DLT in 3 of 29 cases of descending aorta replacement. We can predict difficulty of left-sided DLT placement by the presence of compression of the tracheobronchial tree on chest CT.

Randomized Controlled Trial
[Effect of landiolol on bispectral index scores in patients undergoing lower abdominal surgery].
The aim of this study was to examine the effects of landiolol on bispectral index scores (BIS) during surgery. ⋯ This study suggests that landiolol has no effects on BIS in patients undergoing lower abdominal surgery during sevoflurane-remifentanil anesthesia.

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.
