【摘要】 目的观察国产小包装全氟乙烷(C2F6)在玻璃体视网膜手术中的治疗作用。方法采用环扎和(或)加压联合玻璃体切割手术,全气液交换并注入国产小包装C2F6,对22例视网膜脱离患眼进行治疗,观察视网膜的复位率,气体的眼内动力学及其对眼组织和眼压的影响。结果经过3月~1a的随访,视网膜的复位率达72.73%,小包装气体对眼组织无毒性,术后第1d、2d、3d、6d的眼压分别为(32.02±10·17)mmHg、(23.21±5.82)mmHg、(20.00±4.14)mmHg、(17.44±4.56)mmHg(1kPa=7.5mmHg),眼内寿命为(29·44±3.69)d,眼内半衰期为(12.25±3.49)d。结论小包装国产C2F6不仅安全、可靠,临床使用方便、经济,而且便于携带、储存。更多还原

【Abstract】 Objective To observe the therapeutic effect of small packaged home-made perfluoroethane（C₂F₆） in vitreoretinal surgery.Methods Tewenty-two cases （22 eyes） with retinal detachment were treated with vitrectomy,scleral buckle procedure,fluid/gas exchange and C₂F₆ tamponade.During the follow-up period of 3 months to 1 year,the retinal reattachment rate,the effect of small packaged gas on ocular tissue,intraocular pressure and intraocular gas dynamics were observed and evaluated.Results The retinal reattachment rate was 72.73%.No toxic effect could be found.The intraocular pressure on the 1st day,2nd day,3rd day and 6th day postoperatively was （32.02±10.17）mmHg,（23.21±5.82）mmHg,（20.00±4.14）mmHg,（17.44±4.56）mmHg（1 kPa=7.5 mmHg） respectively.The intraocular gas longevity was （29.44±3.69） days and the half-life time was （12.25±3.49） days.Conclusion The small packaged home-made C₂F₆ is not only safe,reliable,but also effective and economical in vitreoretinal surgery.更多还原
