目的：探讨改良低半卧位在全髋关节置换术后护理中的安全性和有效性。方法将100例全髋关节置换术后患者随机分为平卧位组和改良低半卧位组。主要观察指标为Kolcaba的舒适状况量表（Gen‐eral Comfort Questionnaire ，GCQ）、术后视觉模拟评分（VAS）、呕吐、误吸、假体脱位、压疮和肺部感染等。结果与平卧位相比，改良低半卧位患者术后1h、3h和6h GCQ评分显著增加（P＜0．05）；术后1h、3h和6h VAS评分均有不同程度的减低，但差异无统计学意义（P＞0．05）。二组患者术后呕吐、肺部感染和住院时间差异无统计学意义（P＞0．05），无一例发生误吸、假体脱位和压疮等并发症。结论改良低半卧位在全髋关节置换术后6h内是安全有效的，值得进一步推广。“,”Objective To investigate the safety and efficiency of improved low semi-recumbent in postop‐erative nursing after replacement of total hip .Methods One hundred patients received replacement of total hip were randomly signed into improved low semi-recumbent group or horizontal position group .The pri‐mary outcomes included general comfort questionnaire (GCQ) ,visual analog scale (VAS) ,vomiting ,aspira‐tion ,prosthesis dislocation ,pressure sore and pulmonary infection .Results When compared with horizontal position group ,patients in improved low semi-recumbent group got a significantly higher level of 1-hour postoperative ,3-hour postoperative and 6-hour postoperative GCQ (P 0 .05) .There was no difference between two groups in vomiting ,pulmonary infection and hospital duration(P> 0 .05) .None suffered from aspiration ,prosthesis dislocation and pressure sore .Conclusion Improved low semi -recumbent ,which is a safe and effective during the first 6 hours after replacement of total hip .It is worthy of a wide range of promotion in clinic .
