目的系统评价热盐水预热、碘伏擦拭、大网膜擦拭防止腹腔镜镜头起雾的效果,为临床护理提供可靠证据。方法利用计算机检索国内外相关文献,筛选和查重后采用RevMan5.1软件对数据进行整理和分析。结果共纳入8个研究805例患者,其中热盐水预热组322例,碘伏擦拭组358例,大网膜擦拭组125例。手术30min内腹腔镜镜头起雾率碘伏擦拭组低于热盐水预热组,但差异无统计学意义(P=0.05);大网膜擦拭组与碘伏擦拭组比较,差异无统计学意义(均P>0.05)。结论 3种擦拭方法中碘伏擦拭腹腔镜镜头有较好的防雾效果,如将其作为证据应用则有待大样本对照试验研究以证实。
Objective To systematically evaluate the effect of warm salt water preheating, iodophor rubbing and omentum wiping to prevent the fogging of laparoscopic lens and provide reliable evidence for clinical nursing. Methods Using computer to retrieve relevant literature at home and abroad, the data were sorted and analyzed by RevMan5.1 software after screening and checking. Results A total of 805 patients were enrolled in 8 studies, including 322 warm-water preheating groups, 358 cases of iodophor rubbing and 125 cases of omental rubbing. The laparoscopic lens fogging rate in iodophor wiping group was lower than that in warm saline preheating group within 30min after operation, but the difference was not statistically significant (P = 0.05); there was no significant difference between omeprazole wiping group and iodophor wiping group (All P> 0.05). Conclusion The three kinds of wiping methods iodophor wiping laparoscopic lens has a good anti-fog effect, as evidenced by the application of large samples to be controlled trial to confirm.
