腹腔镜手术内镜镜头防雾方法的研究

Antifogging methodology study for the endoscope lens during laparoscopy operation

目的改变传统镜头防雾方法在腹腔镜手术中的弊端,研究探讨一种既经济又有效的方法。方法选择腹腔镜手术病人120例,随机分为4组,每组30例,比较每组不同时间镜头起雾发生率及镜头摔倒损坏、热盐水撒出污染等意外发生率。结果4种防雾方法术中镜头起雾发生率差异无显著意义(P>0.05),镜头损坏、器械台污染意外发生率差异有统计学意义(P<0.01)。结论用碘伏防雾的方法既经济又使用方便,具有临床应用及推广价值。

Objective To study an economic and operative method of preventing the endoscope lens misting, and avoid the disadvantage of traditional ones. Method 120 patients with laparoscopy operation were selected and divided into 4 groups （group A, B, C and D）. The mist vision incidence and the accident incidence of hot brine splashing were measured and compared. Result There are no significant differences in mist vision incidence among group A and B, C and groups D （P〉0.05）, but there are significantly different in the accident incidence of splashing among those groups （P〈0.01）. Conclusion Method of preventing the endoscope lens from misting with iodophor could be used in clinical practice. Key words Laparoscopy Lens Antifogging
