【摘要】：目的改进实验大鼠经口气管插管定位技术,提高气管插管效率,减少并发症。方法采用临床套管针和静脉留置针组合,设计自制的气管插管定位防逆流装置。60只成年雄性SD大鼠随机分成A、B两组,A组40只,用于定位效果测试,B组20只用于防逆流测试。A组进一步分为A1组采用自行设计的定位装置,A2组采用雾气法,A3组采取棉纤维法进行定位判断。B组分为B1、B2两个亚组,均采取气泡逸出作为定位观察手段,不同的是B1使用圆台状防逆流装置,B2组不使用。采用透光法经口气管插管,观察并记录定位时间、呼气相定位效果、吸气相逆流水柱长度。A1组进一步行气管切开术在直视下明确定位状况。结果在呼气周期内,观察出泡口连续逸出3个以上的气泡,可以确定插管在位良好并通畅。定位时间:A1组需要(1.75±1.02)个呼吸周期,A2组需要(3.30±0.95)个呼吸周期,A3组需要(4.10±0.99)个呼吸周期。A2组与A3组两组间比较差异无显著性(P0.05),A1组明确定位需要的时间明显少于A2、A3组,差异有显著性(P0.01)。B1组最长逆流水柱长度为(3.23±0.53)cm,B2组最长逆流水柱长度为(8.48±1.01)cm。结论自制实验大鼠经口气管插管的定位评估防逆流装置结构简单,使用方便,能有效提高气管插管的定位效率,有较好的实验应用价值。
[Abstract]:Objective to improve the localization technique of endotracheal intubation in rats, improve the efficiency of tracheal intubation and reduce the complications. Methods 60 adult male SD rats were randomly divided into two groups: group A (n = 40), and group A (n = 40), who were divided into two groups: group A (n = 40), group A (n = 40) and group A (n = 40). Group A was further divided into A1 group with self-designed positioning device, A2 group with fog method and A3 group with cotton fiber method. Group B was divided into two subgroups: group B (B1) and group B2 (group B), and group B (group B) was divided into two subgroups: group B (B _ 1) and group B (B _ 2). Bubble escape was used as the location observation method, but B1 used round counter-current protection device, B2 group did not use it. The time of location, the effect of expiratory localization and the length of inspiratory counter-current column were observed and recorded by transtracheal intubation. Group A 1 was further performed tracheotomy to determine the localization status under direct vision. Results during the expiratory cycle, more than three bubbles were observed to escape from the vesicles continuously, and the catheterization was good and unobstructed. Location time: (1.75 卤1.02) breathing cycles in A1 group and (3.30 卤0.95) respiratory cycles in A2 group. There was no significant difference between A2 group and A3 group (P0.05), and the time required for clear location in A1 group was significantly shorter than that in A2 group (A3 group), and there was no significant difference between A2 group and A3 group (P0.05), but there was no significant difference between A2 group and A3 group (P0.05). The longest countercurrent column length in B1 group was (3.23 卤0.53) cm,B2, and the longest countercurrent column length in B1 group was (8.48 卤1.01) cm.. Conclusion the localization evaluation of tracheal intubation in self-made experimental rats is simple in structure and convenient in use. It can effectively improve the localization efficiency of tracheal intubation and has a good experimental application value. [WT5 "HZ] conclusion [WT5" BZ] [WT5 "BZ]
