球后麻醉是内眼手术局部麻醉重要手段之一,其麻醉效果的好坏直接影响手术进程及效果,随着眼科显微手术的发展,手术精细程度的提高,手术时间相对延长,故对局部麻醉效果有着比较严格的要求。为了提高内眼显微手术的质量。我们自90年1月至91年12月内113例显微白内障囊外术患者实行了双路球后麻醉取得了良好效果。麻醉方法: 1、睫状神经节麻醉:让患者直视,于眶下缘中外1/3交界处垂直进针15mm,再使针尖向内上倾斜15°继续进针25mm,此时针尖基本位于肌园锥内或肌园锥附近,回抽无血液即缓慢注入利多卡因1ml,即间断压迫眼球5分钟(压力在30—40mmHg之间)。
Posterior capsular anesthesia is one of the most important means of local anesthesia for intraocular surgery. The anesthetic effect has a direct impact on the progress and effectiveness of the surgery. With the development of ophthalmic microsurgery, the precision of surgery is improved and the operation time is relatively prolonged. Therefore, Narcotic effect has more stringent requirements. In order to improve the quality of intraocular microsurgery. From January 1990 to December 1991, 113 patients with microscopic extracapsular cataract surgery achieved good results after two-way posterior ball anesthesia. Anesthesia method: 1, ciliary ganglion anesthesia: patients with direct vision, in the middle of the infraorbital edge of the outer 1/3 junction perpendicular to the needle 15mm, and then the tip inward tilt 15 ° continue to enter the needle 25mm, the tip is basically located Muscle cones or muscle garden near the cone, pumping back without blood that is slowly injected lidocaine 1ml, that intermittent oppression of the eye 5 minutes (pressure between 30-40mmHg).
