| 摘 要： | 目的 研究CO2气腹及手术体位对眼内压(IOP)的影响.方法 全麻下腹腔镜手术患者36例分为盆腔手术(A组)和胆囊切除术(B组)两组,每组18例.手术体位:A组头低位25°,B组头高位25°.记录麻醉前(T0)、气管插管后5 min(T1)、气腹后5 min(T2)、体位改变后5 min(T3)、体位改变后30 min(T4)和PETCO2降低至正常后(T5)的IOP.结果 两组IOP在全麻诱导后明显下降.A组T4时IOP逐渐增高至(21.0±1.6)mm Hg,T5时降低至(14.6±1.6)mm Hg.B组T4时IOP逐渐增高至(12.1±2.9)mm Hg,T5时降低至(11.1±1.2)mm Hg.两组术中的IOP与PETCO2呈正相关.结论 用丙泊酚全麻诱导可显著降低IOP.头高位手术和保持PETCO2于正常水平是避免IOP升高的重要因素.

| Abstract: | Objective To investigate the influences of carbon dioxide(CO2)pneumoperitoneum and operation position on intraocular pressure(IOP)during laparoscopic surgery under general anesthesia.Methods Thirty-six patients were divided into two groups of udergoing laparoscopic pelvic surgeries(group A)and udergoing laparoscopic cholecytectomies(group B)with 18 cases each.The patients in group A were operated under 25 degrees head-down position and those in group B under 25 degrees head-up position.IOP was recorded befo... |
