摘要
目的 :观察吸氧与否对解痉催眠镇痛法无痛肠镜患者血气分析的影响。方法 :将 2 0例解痉催眠镇痛法无痛肠镜的病人分为吸氧和不吸氧两组 ,并对之作动态血气监测 ,对术前及术中 (用药后第 15分钟 )所得各参数作对比分析。结果 :吸氧组术中PaO2 及SaO2 的升高与术前比有高度显著性意义 (P =0 0 0 0 86和P =0 0 0 0 3 9) ,而PaCO2 值与术前比差异无显著性意义 ;不吸氧组术中 pH和PaO2 的下降与术前比分别有显著性和高度显著性意义 (P =0 0 465 7和P =0 0 0 5 44 1) ,PaCO2 的上升与术前比也有高度显著性意义 ( P =0 0 0 73 7) ,但其最高值仍未达呼衰诊断标准。结论 :解痉催眠镇痛法无痛肠镜对患者呼吸有一定的抑制 ,吸氧不但可有效防止低氧血症 。
Objective To estimate the inference of patient's bloodgas analyses during painless method colonoscopy by oxygen supply.Methods 20 patients who appointed to undergoing painless method colonoscopy by Spasmolysis and Hypno-anesthesia were divided into two groups by oxygen supply(group A) or not (group B). Analyzed the arteious bloodgas of patient just before I.V. durgs and the 15 th minute after durgs were given, then analyzed the data of two groups by students test.Results Contrast to the baseline, the PaO 2? SaO 2 and PaCO 2 of group A were 222 2±77 09 Vs 96 9±8 54?99.8±0.42 Vs 97.8±1.03?40.16±4.01 Vs 39.27±3.33(P=0.00086?P=0.00039和P=0.657),But in group B, they were 85.2±10.93 Vs96.8±8.43?96.7±1.946 Vs97.5±0.849?41.03±3.789 Vs 38.42±2.76(P=0.00544?P=0.258和P=0.00737),Respectively. Conclusion The painless Colonoscopy by Spasmolysis and Hypnoanesthsia can depress respiratory lightly. oxygen supply can not onlyprevent hypoxemia, but also can prevent the cumulation of carbon dioxide.
