不同排痰方式对预防胸部手术病人肺部并发症的对照研究

A Clinical controlled study of different sputum excretion for the precaution of thoracic surgery complications

目的探讨不同排痰方式对预防胸部手术后肺部并发症的影响。方法 86例胸部手术病人随机分为实验组44例,术后给予排痰机振动排痰,对照组42例,术后给予常规人工拍背排痰。比较两组患者的感受、术后72 h的生命体征变化及术后并发症的发生率。结果实验组排痰过程中疼痛等不适感发生率为27.3%明显低于对照组73.8%(P<0.05);实验组与对照组相比肺不张(4.5%VS 21.4%)、肺感染(4.5%VS 16.7%)、发热(2.3%VS 14.3%),实验组明显低于对照组(P<0.05);实验组与对照组相比,术后72 h心率、呼吸、血压无明显差别(P>0.05),血氧饱和度明显高于对照组(P<0.05)。结论排痰机排痰可显著降低胸部手术后患者不适感及术后并发症发生率。

Objective To evaluate the effect of different sputum excretion for the precaution of thoracic surgery complications. Methods 86 patients after thoracic surgery were randomly divided into two groups. The control group （ n = 42） were given conventional regular artificial expectoration, and the experimental group （ n = 44） were given mechanical vibration expectoration. The patients＇ recep- tions, the incidence of postoperative complications and vital signs 72 hours after operation were compared between the two groups. Results The uncomfortable receptions, lung atelectasis, lung infection and fever in the control group was much higher than that in the experi- mental group （ P 〈 0. 05 ）, but the HR, RR and BP of the two groups had no significant difference （ P 〉 O. 05 ）. Besides, the saturation of blood oxygen was obviously higher in the experimental group than that in the controls （ P 〈 0. 05 ）. Conclusion Expectoration by vibra- tion machine can significantly reduce the incidence of postoperative complications and patient＇s discomfortableness after thoracic surgery.
