The effect of breast-feeding on newborns' pain caused by heel prick

目的探索母乳吸吮对足月新生儿足跟采血疼痛的影响。方法便利抽取北京某医院产科病房60例接受足跟采血筛查的足月新生儿,随机分为两组,各30例。干预组新生儿在足跟采血前2min至采血结束后8min吸吮母乳。对照组按常规给予足跟采血。使用疼痛面容、啼哭、心率、血氧饱和度指标评估新生儿疼痛反应。结果干预组新生儿足跟针刺后疼痛面容和啼哭出现的时间晚于对照组(P<0.05),啼哭人数少于对照组(P<0.05),疼痛面容和啼哭的持续时间也短于对照组(P<0.05),采血过程中和采血结束后1-4min的血氧饱和度均高于对照组(P<0.05),采血结束后血氧饱和度的恢复时间也显著短于对照组(P<0.05)。结论母乳吸吮能有效减轻足月新生儿足跟采血的疼痛程度。
