简介:目的探讨商调音乐对肺癌患者化疗期间睡眠状况的影响。方法选取2014年10月-2015年1月收治于同济大学附属上海市肺科医院的肺癌患者57例,采用随机数字法分为观察组27例和对照组30例,对照组按照肺癌护理常规护理,观察组在接受常规护理的同时,给予商调音乐护理,音乐选择《阳春白雪》、《春江花月夜》和《平湖秋月》等,每天临睡前30min,共1个化疗周期约为28d,两组患者均在化疗前1d和化疗第28天采用匹兹堡睡眠质量指数量表(PSQI)评分,统计两组患者PSQI平均得分和在此期间化疗完成情况及助眠药物服用情况。结果观察组患者均能顺利完成化疗,对照组有1例患者未能完成化疗;两组患者PSQI平均得分比较差异有统计学意义(P〈0.05);两组患者助眠药物服用情况比较差异有统计学意义(P〈0.05)。结论商调音乐可以改善肺癌患者化疗期间的心境状况,提高患者的睡眠质量,有助于减少助眠药物的服用量,有利于患者的身心健康。
