本文用球后二次麻醉法对64眼进行眼内手术。球后二次麻醉可分二个步骤,其一为用3％奴佛卡因3毫升加适量(0.1％)肾上腺素的药液,从眶上缘内、中1/3交界处向眶尖进针,于距眶尖1.4厘米阻滞支配眼外肌的神经。其法二是在前一次麻醉效果不理想时,眼肌麻痹而无瞳孔散大者补做二次,麻药量不超过2毫升,在结膜下穹隆部于角膜中央稍偏鼻侧向睫状节方向进针,麻醉睫状神经节。结果绝大部分只一次即可达到眼内、外肌麻痹,眼球痛觉消失。麻醉彻底,术中眼球固定不动,便于手术操作;尤其对白内障摘除术并可避免术中产生合并症,效果确切显著。
In this paper, the second post-ball anesthesia 64 eyes for intraocular surgery. The ball after the second anesthesia can be divided into two steps, one with 3% novicocaine plus the right amount of (0.1%) adrenaline solution, from the supraorbital margin, 1/3 junction to the orbital tip Into the needle, at a distance of 1.4 cm from the orbital apex block the nerves that underlie the extraocular muscles. The second method is not satisfactory in the previous anesthesia, ophthalmoplegia and no mydriasis to make secondary, anesthetic does not exceed 2 ml, in the subfornical dome in the cornea slightly nasal lateral ciliary section Directions into the needle, ciliary nerve anesthesia. Most results can be achieved only once the eye, outer muscle paralysis, eyeball pain disappeared. Thorough anesthesia, intraocular fixed eye surgery, ease of operation; especially for cataract surgery and avoid intraoperative complications, the effect is obvious.
