浅层吸痰法在危重症人工气道患者中的应用

Application study of on critically ill patients with artificial airway

①目的探讨浅层吸痰方法对危重症人工气道患者的影响及最佳的吸痰方式。②方法选择危重症人工气道患者96例,采取随机分组的方法将其分为观察组和对照组。观察组采用浅层吸痰法,对照组采用常规吸痰法。观察两组吸痰前、吸痰后3min的心率、呼吸、血压和经皮血氧饱和度(SPO2)以及人工气道建立当天与第3天气管黏膜损伤情况。③结果两组吸痰前心率、呼吸、血压、SPO2和人工气道建立当日气管黏膜损伤情况无显著性差异(P>0.05)。两组在吸痰后3min,患者的心率、呼吸、血压、SPO2及建立人工气道第3天气管黏膜损伤情况有显著性差异(P<0.05)。④结论浅层吸痰法可减轻对气道的刺激及对气管黏膜的损伤。

Objective To study the effects of different suction methods on critically ill patients with artificial airway,to detect the best suction methods. Methods 96 critically ill patients with artificial airway were divided two groups：the expermental group（47cases） and the control group （49cases）. The shallow suction method and the routine suction method were applied in the groups, respectively. The patientsheart rate, respiratory tate, blood pressur, SPO2 before suction and 3 min after suction and the injury of tracheal mucosa were compared under dierent suction methods. Results There were no difference in the patientsheart rate, respiratory rate, blood pressur, SPO2 and the injury of tracheal mucosa before suction （ P 〉 0.05 ）. But there were significant difference in those after 3 min （ P 〈 0.05 ）. The effects were light in Patientsheart rate respiratory rate, blood pressur, SPO2 and the injury of tracheal mucosa with shallow suction method compared with routine suction method. Conclusion The shallow suction method is safe and effective suction method with the patients;cital signs relatively stable and the light injury of tracheal mucosa
