Comparison between propofol and dexmedetomidine in postoperative sedation after extensive cervical spine surgery.

Purpose: Patients undergoing extensive cervical spine surgery (ECSS) occasionally require emergency reintubation due to postoperative airway complications. To avoid it, an endotracheal tube is retained in patients maintained under sedation overnight. This study was conducted to determine whether dexmedetomidine would be superior in sedative effects to propofol for postoperative sedation after ECSS.

[Relationship between magnesium concentration in cerebrospinal fluid and delayed cerebral ischemia in patients with aneurysmal subarachnoid hemorrhage].

Background: The present study was conducted to determine the relationship between magnesium concentration in cerebrospinal fluid (CSF) and delayed cerebral ischemia (DCI) in patients with subarachnoid hemorrhage (SAH).

Methods: We studied 39 consecutive patients undergoing surgery after SAH. A spinal drainage catheter was inserted into the lower lumbar vertebrae before surgery.

QTc interval and neurological outcomes in aneurysmal subarachnoid hemorrhage.

Background: Prolonged heart rate-corrected QT (QTc) interval is frequently observed in subarachnoid hemorrhage (SAH). This study was conducted to determine the relationship between QTc interval and neurological outcome during the acute posthemorrhagic period after aneurysmal SAH.

Methods: We studied 71 patients undergoing surgery who were admitted within 24 h after the onset of aneurysmal SAH.
