摘要
目的分析微创玻璃体切除术中发生气体灌注迷流的机制和处理措施。方法回顾性分析2016年1月至2017年1月玻璃体手术440例(440只眼)的临床资料,其中23G手术412例,20G手术28例。结果23G玻璃体切除术中发生气体灌注迷流至前房和玻璃体前间隙者15例,而20G玻璃体手术中未观察到气体灌注迷流。这种现象主要是由微创切口套管不能完全穿透玻璃体皮质等因素所造成的。解决的方法是放出前房气体并重新调整灌注头的状态。结论气体灌注迷流在23G玻璃体切除术的发生率高于20G玻璃体手术(χ2=4.141,P=0.042)。正确认识其原因,及时采取相应措施进行预防和对症处理。
Objective To analyze the pathogenic mechanisms and management methods of infusion air misdirection in microincisional vitrectomy.Methods The data of 440 eyes of 440 cases received vitrectomy from Jan.2016 to Jan.2017 were retrospectively analyzed.There were 412 cases of 23 G vitrectomy and 28 cases of 20 G vitrectomy.Results Infusion air misdirection occurred in 23 G vitrectomy in 15 eyes of 15 cases when performing air-fluid exchange.No case happened in 20 G vitrectomy.Infusion air misdirection was mainly caused by inability of trocar tip to penetrate the vitreous cortex and other factors.The management was released anterior chamber gas and readjusted infusion cannula.Conclusion Infusion air misdirection happens more frequently in 23 G vitrectomy than 20 G vitrectomy(χ2=4.141,P=0.042).This complication can be avoided or treated appropriately if recognized.
