在眼科手术中,球后阻滞性麻醉是最常用、最重要的局麻方法。其麻醉效果的好坏,直接影响手术的成败。怎样才能打好这一针麻醉呢?关键在于是否真正将药液注射到外直肌与视神经之间的睫状神经节旁。目前比较通用的方法是经下睑皮肤外1/3处刺激入眶内法。也有部分书上介绍经下穹窿结膜处刺入眶内法。那么究竟哪一种方法更好呢?笔者从1986年以来,对两种方法进行了比较,其结果是:1986年1月至12月,共行经下睑皮肤作球后阻滞性麻醉手术96例,其中11在例手术过程中有眼球颤动,麻醉不良占。11.4%。1987年1月至1988年4月间,共行经下穹窿结膜作球后阻滞性麻醉90例,其中仅3例术中有眼球颤动。麻醉不良
In ophthalmic surgery, posterior capsular block anesthesia is the most common and important method of local anesthesia. The quality of its anesthetic effect, a direct impact on the success of surgery. How to lay this needle anesthesia? The key is whether the real injection of liquid medicine to the lateral rectus and optic nerve between the ciliary ganglion. The current more common method is to stimulate the lower eyelid skin 1/3 into the orbital method. There are also some books introduced through the fornix conjunctiva stabbing into the orbital method. So what kind of method is better then? The author since 1986, the two methods were compared, the result is: January 1986 to December, after a total of two under the skin via posterior capsular block anesthesia 96 Cases, of which 11 cases during the operation of the eye tremor, poor anesthesia accounted for. 11.4%. From January 1987 to April 1988, a total of 90 cases underwent supracorpla for conjunctival blockade anesthesia, of which only 3 patients had ocular fibrillation. Poor anesthesia
