球周麻醉(peribulbar anaesthesia)在1970年被Kelman介绍后,经不断改进,已被世界不少地区医院使用,这种麻醉方法尚未被眼科同行广泛使用。笔者近来用球周麻醉代替球后麻醉,观察了28例病人(36眼),均得到与球后麻醉相同的镇痛和肌肉麻痹的效果,却降低和避免了球后麻醉引起的并发症。现将结果报告如下。操作方法麻药注射部位和方法:第一注射点在眶下缘外中1/3交界处进针,一般从皮肤面刺入,先在皮下注射麻药0.5ml(本组病例均使用2%普鲁卡因),针头向深部推进,于
Perhabulbar anaesthesia, introduced by Kelman in 1970, has been continuously improved and used by many regional hospitals in the world. This method of anesthesia has not been widely used by ophthalmologists. The author recently used ball anesthesia instead of retrobulbar anesthesia, observed in 28 patients (36 eyes), were given the same post-nociceptive analgesic and muscle paralysis effect, but to reduce and avoid post-nociceuria complications. The results reported below. Method of anesthesia injection site and method: the first injection point in the infraorbital margin of the outer 1/3 at the junction of the needle, the general penetration from the skin surface, the first subcutaneous injection of 0.5ml of anesthetic (the patients were used 2% Prussian Caffeine), the needle to the depth of advance, at
