We now have an additional tool to help in managing complicated retinal detachments. We look forward to the day when we can leave the liquid without having to remove it because of the possibility of ocular complications.

目的观察部分液体通气(partial liqu id ventilation,PLV)联合气道内给予血管扩张药伊洛前列素对急性肺损伤(acute lung in jury,ALI)兔肺气体交换、肺力学方面的影响。方法健康大白兔24只,用油酸混合兔血清复制成ALI模型后随机分为3组...目的观察部分液体通气(partial liqu id ventilation,PLV)联合气道内给予血管扩张药伊洛前列素对急性肺损伤(acute lung in jury,ALI)兔肺气体交换、肺力学方面的影响。方法健康大白兔24只,用油酸混合兔血清复制成ALI模型后随机分为3组。各组采用不同治疗方法:常规机械通气组(conventionalm echan ical ventilation,CMV);部分液体通气组(PLV);联合组为PLV+雾化吸入伊洛前列素(iloprost)。分别监测各组治疗前后各时相点PaO2、PaCO2及肺静态顺应性(Cstat)、肺动脉平均压(pu lmonary arterial pressure,PAP)的变化。结果联合组PaO2从(104±16)mmHg升高到(236±38)mmHg(P<0.05),肺动脉平均压从(22±5)mmHg降低到(16±3)mmHg(P<0.05)。联合组PaO2的升高及PAP的降低优于CMV组和PLV组。结论部分液体通气联合雾化吸入伊洛前列素不仅对于改善ALI肺氧合功能优于单纯部分液体通气,还可减低部分液体通气对肺血流动力学的影响,降低肺动脉高压。展开更多
