左三叉神经根微血管减压术两种体位的比较研究

The comparative study of two kinds of position of the left trigeminal nerve root microvascular decompression

目的探讨三又神经根微血管减压术摆置侧俯卧位时对腋神经的压迫程度以及术后对患者造成手臂酸麻等症状的情况，为神经外科施行三叉神经根微血管减压术时选择合适的侧俯卧位提供依据。方法将44例实施三叉神经根微血管减压术的患者随机分成观察组与对照组各22例，观察2组患者在摆侧俯卧位时右手臂不同放置位置时对于术后患者的手臂功能的影响程度。结果手术完毕患者清醒后2组患者的手臂感觉、对疼痛的反应、上肢肿胀情况及活动灵活度比较差异显著。结论对于三叉神经根微血管减压术的侧俯卧位摆置需将患者的头部往前移，使右上肢脱离床体进行低位置固定，可以防止右上肢受压严重而造成神经受损或手臂功能受损。

Objective To discuss the application effect of lateral prone position in the left trigemi- hal nerve root microvascular decompression on the degree of compression on axillary nerve and arm discomfort, in order to supply evidence for selection of a suitable position during trigeminal nerve root microvascular decompression. Methods 44 cases who underwent microvaseular decompression of trigeminal nerve roots were randomly divided into the observation group and the control group with 22 cases in each group. They were in lateral prone position with their arms placed in different positions. The influence on arm function was observed in two groups. Results The arm feeling, response to pain, the upper limb swelling and flexibility were statistically significant between two groups. Conclusions For lateral prone position arrangements during microvascular decompression of trigeminal nerve root, the patients＇ head should be moved ahead,the fight arm should be out of bed and be fixed in a lower position, so that nerve and functional damage can be prevented by avoiding decompression of the fight upper arm.
