爆炸引起的眼外伤病例特征分析

目的：探讨爆炸引起的眼外伤病例特征。方法：收集大坪医院2000-01/2007-03间所有因爆炸引起眼外伤住院患者的病例进行统计学分析。记录患者资料,受伤原因,初始及最终视力,药物治疗及住院时间。结果：共103例116眼,其中鞭炮炸伤71眼（61.2%）,炸药（含雷管）22眼（18.9%）,玻璃瓶爆炸10眼（8.6%）,其他原因炸伤13眼（11.2%）。2月份鞭炮炸伤是最主要的原因,发病占到40.9%。47.0%的鞭炮炸伤患者至少需要住院2wk治疗。受伤后只有11.2%的患者视力能够达到0.1以上,经过治疗可达33.6%。结论：爆炸引起的眼外伤,破坏程度大,虽经积极抢救治疗,预后一般较差。做好保护与预防才能真正降低该病的发病率。

Ocular injuries caused by explosive substance

AIM:To evaluate the incidence and characters of the explosive substance induced ocular injuries. METHODS: All patients were treated in the Ophthalmology Department ward of Daping Hospital between January 2000 and March 2007 for ocular injuries caused by explosive substance were reviewed. Patients demographics, causes of injury, initial and final visual acuity, medical intervention, and the length of hospitalization time were noted. RESULTS: Totally 116 eyes of 103 cases were identified. Firecracker caused 71 eyes(61.2%), engineering explosive caused 22 eyes(18.9%), explosion of glass bottles caused 10 eyes(8.6%), and other reasons caused 13 eyes(11.2%). Firecracker induced injuries had the highest incidence rate in February(40.9%). 47.0% patients caused by firecracker needed about 2 weeks therapy in the hospital. Only 11.2% visual acuity were 20/200 or better on presentation and after therapy it was 33.6%. CONCLUSION: Explosive substance may cause severe eye injuries, appropriate caution and prevention would be helpful to decrease the incidence rate of this kind of ocular injury.
