Myopia has been identified as a risk factor for globe perforation during regional anaesthesia for cataract surgery. We conducted this study to evaluate efficacy of single injection percaruncular peribulbar anaesthesia for phacoemulsification in patients with axial myopia.
Eighty patients with axial myopia received percaruncular peribulbar anaesthesia and were evaluated for incidence of major or minor complications. Also surgeon and patients' satisfaction and their comment on operative conditions were noted.
Of the 80 patients 51 patients had posterior staphylomas. About three quarters of the patients developed adequate akinesia in 10 min. Remaining 25% received second injection with the same technique but with less volume after which the percent of patients with adequate akinesia rose to 91%. Adequate analgesia developed in almost all patients and only in one patient, intravenous analgesia was necessary to complete the operation. All operations were completed uneventfully. No perforations or penetrations were recorded and no other major complications were encountered. About 97% of the surgeons and 96% of the patients found the operative conditions satisfactory.
Using single injection percaruncular peribulbar local anaesthesia for phacoemulsification in patients with axial myopia is an effective technique.
近视已被确认为白内障手术区域麻醉期间眼球穿孔的危险因素。我们开展这项研究以评估单剂量球周肌锥内麻醉用于轴性近视患者超声乳化手术的效果。
80例轴性近视患者接受球周肌锥内麻醉，并对主要或次要并发症的发生率进行评估。同时记录外科医生和患者的满意度以及他们对手术条件的评价。
80例患者中，51例有后巩膜葡萄肿。约四分之三的患者在10分钟内出现了足够的眼球运动麻痹。其余25%的患者采用相同技术但减少剂量进行了第二次注射，之后眼球运动麻痹充分的患者比例升至91%。几乎所有患者均产生了足够的镇痛效果，只有1例患者需要静脉镇痛来完成手术。所有手术均顺利完成。未记录到穿孔或穿透情况，也未遇到其他主要并发症。约97%的外科医生和96%的患者对手术条件感到满意。
对于轴性近视患者，采用单剂量球周肌锥内局部麻醉进行超声乳化手术是一种有效的技术。
