开胸术后排痰困难患者吸痰方法的研究

Study dincal effects of oropharynx airway in post-thoracotomy patients with sputum drainage diffculties

目的探讨经口咽通气管吸痰在开胸手术后患者排痰困难中的应用效果。方法随机将96例开胸手术后排痰困难患者分成观察组和对照组各48例，观察组采用口咽通气管吸痰，对照组采用常规经口鼻腔吸痰，比较两组吸痰前后心率、血压、氧分压、血氧饱和度以及两组的吸痰效果、吸痰时间、一次插管成功、肺部相关并发症等情况。结果两组患者吸痰后血氧饱和度、氧分压、吸痰操作时间、吸痰效果、一次插管成功、患者接受度、相关并发症的比较，差异有统计学意义（t分别为11．16，11．15，15．20，8．18，6．10，6．56，16．70，4．89；X。分别为5．76，4．44；P〈0．05）；心率、血压差异无统计学意义（P〉0．05）。结论经口咽通气管吸痰的方法对畅通呼吸道、改善呼吸、缓解缺氧都具有明显满意的临床效果。

Objective To evaluate the effectiveness of oropharynx airway in post-thoraeotomy patient with sputum drainage difficulties. Methods 96 post-thoraeotomy patients with sputum drainage diffieuhiet were divided randomly into control group and test group, expeetoration through oropharynx airway group ant expectoration through nasal cavity group. Heart rate, hlood pressure, P02, SpO2 , sputum suction time] successful intubation rate, effect of sputum suction and pulmonary associated complications before and afte sputum aspiration between two groups were analyzed. Results There are significant differences in SpO2 P02, sputum suction time, successful intubation rate, effect of sputum suction and pulmonary associate~ complications before and after sputum aspiration between two groups （ t = 11.16,11.15,15.20,8.18,6.10 6.56,16.70,4.89;X2 = 5.76,4.44;P 〈 0. 05）, while there are no significant differences in HR and Bt （P 〉0. 05 ）. Conclusions Sputum suction through oropharynx airway is benefit to keep airway clean, improve respiration and relieve hypoxia.
