超声定位联合毫针引导取浅表非金属异物探讨

[目的]探讨在超声定位和毫针引导下取浅表非金属异物的经验和方法。[方法]选择1999年至2012年体表留有非金属异物的患者34例，均先用超声多角度扫描确定非金属异物位置、大小、数量、形态和异物周围组织反应情况，以异物体表投影点为毫针刺入点，在超声监测下逐步调整进针角度及深度，缓慢抵近并标定异物。固定毫针，以此针为引导，逐层切开，找到并取出异物。[结果]本组33例均能顺利找到并一次性取出非金属异物，1例分两次清除，无异物残留，未损伤重要组织，创面愈合均良好。非金属异物以玻璃、砂石、竹、木质为主。[结论]超声定位、毫针引导取浅表非金属异物是一种操作简单、安全、值得推广的好方法。

Analysis of Removal the Non-metallic Foreign Bodies of Superficial Tissue under the Location of Ultrasonic and the Guidance of Acupuncture Needle

[Objective] To analyze the experience and methods of removal the non-metal ic foreign bodies in the superficial tissue under the location of ul-trasonic and the guidance of acupuncture needle. [Method] First find the non-metal ic foreign bodies and observe the trauma around them by ultrasonic scanning, then use needle to puncture and approach the foreign bodies gradual y for location. Remove the foreign bodies according to the guidance of nee-dle in the end. [Result]Total foreign bodies could be removed easily without any remains in these cases, and trauma recovered wel . 33 cases were removed out smoothly the non-metal ic foreign bodies for just one time, and 1 case for two times. [Conclusion] Removal of the superficial non-metal ic foreign bodies under the location of ultrasonic and the guidance of needle is a great method of security,operating simply,being worthy of popularization through comparing with other methods.
