简要总结
This study aims to investigate the effect of Sphenopalatine Ganglion Block on ICP and arterio- jugular venous oxygen difference (AJVDO2) and jugular bulb oxygen saturation (SjVO2). Throughout this study, the efficacy of Sphenopalatine Ganglion Block as scalp block in craniotomy operation will be assessed, and the effect of SPGB on cerebral hemostasis during craniotomy will be evaluated by monitoring of both ICP, AJVDO2 and SjVO2.
详细描述
This study was performed in the Neurosurgical operating room and included 52 patients allocated into two groups: the treatment group (block group) and the control group (non-block group). 26 patients enrolled in block group and 26 patients in non-block group.
Intraoperative ICP monitoring by subdural ICP monitors will be done every 20 minutes in both block and non- block groups until craniotomy has been occurred, then at the time of closure of the dura . Arterio- jugular venous oxygen difference and Jugular venous bulb oxygen saturation changes will be recorded every 20 minutes in block and non- block groups throughout time of the surgery till closure of the dura.

结局指标
主要结局
Intracranial Pressure
时间窗: Every 20 minutes until time of initial craniotomy, then again after the dura was sutured.
ICP changes checked by a subdural ICP monitor that positioned after the first burr hole at the opposite side of the tumor immediately after induction of anesthesia. ICP monitoring will be conducted every 20 minutes until time of initial craniotomy and at time of closure of the dura.
次要结局
- Jugular venous bulb oxygen saturation and cerebral arteriovenous oxygen content difference.(Every 20 minutes throughout the operation period.)
