冠心病病人PCI术后睡眠质量的观察

目的观察冠心病病人经皮冠状动脉介入治疗（PCI）术后睡眠质量及影响因素，并探讨护理干预提高病人睡眠质量的有效途径。方法将PCI术后病人104例作为研究对象，随机分为实验组和对照组，各52例。实验组PCI术后全程给予干预护理，对照组给予常规护理。采用自编睡眠质量影响因素调查表和匹兹堡睡眠指数量表（PSQI），对住院病人睡眠质量和影响因素进行调查。结果两组影响睡眠质量比较集中的因素依次为身体不适、焦虑、环境、医源性因素及生活习惯，两组间差异无统计学意义（x^2=0．04～0．22，P〉0．05）。实验组PSQI总分、主观睡眠质量、入睡时间、睡眠时间、睡眠效率、睡眠障碍、催眠药物、日间功能的分数均低于对照组，两组间差异有显著性（t=3．987～38．722，P〈0．01）。实验组并发症的发生率低于对照组，住院天数短于对照组，差异有显著性（x^2=2．66，t=8．90，P〈0．01）。实验组的满意度为96％（50／52），对照组为77％（40／52），两组比较差异有显著性（x^2=8．25，P〈0．01）。结论有效的护理干预能改善PCI术后病人的睡眠质量，有利于疾病的康复。

A CLINICAL STUDY OF SLEEP QUALITY IN PATIENTS AFFER PERCUTANEOUS CORONARY INTERVENTION

Objective To investigate the factors influencing sleep quality in patients with coronary heart disease after percutaneous coronary intervention （PCI）, and search for effective ways to improve sleep quality by nursing intervention. Methods This study consisted of 104 post-PCI patients who were evenly divided into experiment group and control group in random. Nursing intervention was given to the experiment group, and routine nursing to the control. Pittsburgh Sleep Quality Index （PSQI） questionnaire and a self-designed questionnaire were used for the study. Results The main factors influencing sleep quality were malaise, anxiety, environment, iatrogenic factors and living habit, the difference was not significant between the two groups （x^2= 0.04-0.22 ,P〉0.05）. Compared with the control group, the total PSQI score, subjective sleeping quality, hours and efficiency of sleep, sleep disorder, hypnotic drug and fraction of daytime performance were lower （t = 3. 987- 38. 722, P〈0.01）, the complication rate was lower and hospital day shorter （x^2 =2.66,P〈0.01）, the satisfaction rate （96%） was higher （x^2=8.25,P〈0.01）. Conclusion Active nursing intervention for post-PCI patients could improve their quality of sleep and promote their recovery.
