显微血管手术中,暂时阻断血管是一种有效的方法,有利于分离和永久夹闭脑动脉瘤,然而仍有一些问题影响该技术的安全性,作者于1991—1993年间在126例132次动脉瘤手术中,采用暂时阻断血管和特殊抗缺血麻醉方案。动脉瘤夹闭暂时阻断血管期间使用诱发高血压、浅低温和静脉输入甘露醇。病人睡冰毯使体温控制在33—34C,阻断血管时静脉输入盐酸脱羟肾上腺素使收缩压达150mmHg。血管阻断前5—15分钟,静脉输甘露醇(100mg)。132次手术中13次术后有新的神经系统损害或CT扫描新的低密度灶,总中风率
Microvascular surgery, the temporary blocking of blood vessels is an effective method to facilitate the separation and permanent clipping of cerebral aneurysms, however, there are still some problems affecting the safety of the technique, the author in 1991-1993 in 126 cases of 132 Secondary aneurysm surgery, the use of temporary blocking blood vessels and special anti-ischemic anesthesia program. Aneurysm Closure Temporarily block the use of blood vessels during induced hypertension, hypothermia, and intravenous mannitol. Sleep ice blanket patients to control body temperature in the 33-34C, intravenous infusion of phenylephrine hydrochloride to block the blood vessels so that the systolic blood pressure up to 150mmHg. 5-15 minutes before vascular occlusion, intravenous mannitol (100mg). Thirteen of the 132 surgeries had new neurological damage or CT scan of new low-density lesions, total stroke rate
