摘要
目的:探讨球筋膜下麻醉新技术在内眼手术麻醉中的优点及其作用机理。方法:应用球筋膜下麻醉456只眼,其中白内障超声乳化人工晶体植入77只眼,ECCEIOL 346只眼,小梁切除33只眼,在颞下方近角巩缘球结膜小切口伸入钝性硅胶注射管注射2％利多卡因和0.75％布比卡因混合液2ml,球筋膜下充满药液,即可开始各种手术操作。结果:456只眼手术安全,取得同球后、球周麻醉一样的效果。结论:球筋膜下麻醉采用钝性硅胶注射管避免了对视神经、动、静脉血管、眼肌及眼球壁的机械性损伤,注射方法简单,临床应用证明,它是一种安全、有效的局部麻醉的方法。眼科学报1999;15:127—128。
Objective:To probe the advantage, indications and its mechanism of anaesthesia at intraocular operation with infrafaseia bulbi anaesthetic (IBA) technique. Methods: 456 eyes were operated with the anaesthesia in infrafaseia bulbi, including 77 eyes for phacoemulsification intraocular lens implantation, 346 eyes for modern surgical extracapsular cataract extraction and intraocular lens implantation, 33 eyes for trabeculectomy. 2ml of mixture of 2% Lidocaine and 0.75% Bupivacaine were injected at infratemporal near bulbi conjunctiva of limbus through the blunt silicone canal, which entered the fascia bulbi via a small incision and reached the equator of the eyeball. When the injection of the mixture filled up the fascia bulbi the surgery could be performed.
Results: IBA applied in 456 eyes had shown the same effect as posterior fascia bulbar and peripheral fascia bulbar anaesthesia. IBA is a safe method.
Conclusion: It is avoided the mechanical injure to optic nerve, artery, vein, muscle and wall of eyeball with IBA using blunt silicone injecting canal. It is proved in our clinical practice that this is a saft and efficient local anaesthetic method. Eye Science 1999;15:127 - 128.
