近几年喉科领域开展的支撑喉镜下的喉显微手术,为了提高疗效和安全性,对麻醉的要求很高。已往的局麻已不能完成此类手术。我们采用高频喷射通气(HFJV),气管内全麻能保证手术的安全和成功。但也随之带来术中呼吸、循环等并发症发生的可能性。我院自1989年至1993年成功地进行了150例喉显微手术。现就术中并发症的预防总结如下。1 麻醉方法:术前15min 静滴芬太尼0.05mg、阿托品0.5mg,1%地卡因喉部表面麻醉后,硫喷妥钠250-380mg 或乙托米酯18-20mg+琥珀酰胆碱100mg 快速诱导,气管内插管,接高频喷射呼吸机进行 HFJV。置入支撑喉镜,再次表麻。术中用芬太尼、乙托·米酯、琥珀
In recent years, laryngology carried out in the field of laryngoscopic throat microsurgery, in order to improve the efficacy and safety of anesthesia demanding. Previous local anesthesia can not complete such surgery. We use high-frequency jet ventilation (HFJV), tracheal general anesthesia to ensure the safety and success of surgery. However, it also brings the possibility of intraoperative respiratory and circulatory complications. Our hospital successfully conducted 150 laryngeal microsurgery from 1989 to 1993. Prevention of intraoperative complications are summarized below. 1 anesthesia method: 15 minutes before surgery, intravenous infusion of fentanyl 0.05mg, atropine 0.5mg, 1% dexamethasone throat surface anesthesia, thiopental 250-380mg or ethyl tamarind 18-20mg + succinylcholine 100mg Rapid induction, endotracheal intubation, then high-frequency jet ventilator HFJV. Into the support laryngoscopy, table linen again. Intraoperative fentanyl, ethyl care rice ester, amber
