The bispectral index (BIS) is widely used to measure anesthetic levels in the perioperative period. In our hospital, the BIS monitors (A-2000) are connected to bedside monitors and display BIS values on them through outside input. ⋯ One possible reason is thought that the BIS Quatro Sensor transmits both EEG signals and sensor information to the BIS A-2000 monitor separately. BIS A-2000 monitors may process EEG signals and sensor information individually, and transfer BIS parameters to the external equipments, regardless of sensor information.

The endovascular repair of thoracic aortic aneurysm and abdominal aortic aneurysm has become a promising alternative for open surgical graft replacement. The benefits of EVAR include less invasiveness, no need for cardiopulmonary bypass or differential lung ventilation, less blood loss, shorter hospital stay and reduced perioperative morbidity and mortality. ⋯ Previous abdominal aortic aneurysm repair, prolonged hypotension, severe atherosclerosis of the thoracic aorta, injury to the external iliac artery, and more extensive coverage of the thoracic aorta by the graft are reported to be the risk factors for paraplegia after TEVAR. In such cases, strategies to protect the spinal cord from ischemia including lumbar cerebrospinal fluid drainage should be taken.

Clinical Trial
[Effectiveness of underbody type forced-air warming blanket during endovascular aneurysm repair].
Intraoperative hypothermia is frequently observed during endovascular aneurysm repair (EVAR), leading to postoperative serious sequelae. We evaluated the effectiveness of underbody type forced-air warming blanket against hypothermia during EVAR. ⋯ Underbody type forced-air warming blanket is effective to prevent intraoperative hypothermia during EVAR.
