2种干预方式对新生儿疼痛影响的研究

目的 比较音乐干预与音乐+非营养性吸吮干预合用对足跟采血所致新生儿疼痛的干预效果.方法 将新生儿重症监护室中胎龄≥28周的75例新生儿随机分为音乐干预组、音乐+非营养性吸吮组及对照组,察足跟采血时3组新生儿啼哭和疼痛面容的持续时间、心率(HR)和血氧饱和度(SpO2)的变化、采血结束后90 s内的啼哭例数.结果 音乐干预组、音乐+非营养性吸吮组的新生儿疼痛面容和啼哭的持续时间、HR和SpO2恢复至采血前基线水平所需的时间均显著短于对照组,HR、SpO2的变化幅度显著低于对照组;乐+非营养性吸吮组新生儿的啼哭、疼痛面容的持续时间、HR恢复至采血前基线水平所需的时间均显著短于音乐组的新生儿.结论 足跟采血时音乐干预或音乐+非营养性吸吮合用均能减轻新生儿疼痛.音乐干预+非营养性吸吮合用对音乐干预的止痛效果有加强作用.

Research in analgesic effect of two intervention methods on the newborns' pain

Objective To compare the effect of music and music plus non- nutritive sucking interventions on the newboms' pain caused by heel lance. Methods 75 neonates from the neonatal intensive care unit (NICU) whose gestational age=28 weeks were randomly separated into the music group,the music plus non-nutritive sucking group and the control group. The newboms' crying and grimacing,heart rate (HR), oxygen 9at-uration(SpO2) changes and times of crying 90 seconds after heel lance were observed. Results The cry-ing and grimacing time,the convalescence time of HR and SpO2 in the two intervention groups were significantly shorter than the control group.And the amplitude of HR, SpO2 changes was also significantly smaller than the control group.The crying and grimacing time and the convalescence time of HR and SpO2 in the music plus non-nutritive sucking group were significantly shorter than the music group. Conclusions Music or music plus non-nutritive sucking can ease newboms' pain caused by heellance.Music plus non-nutritive sucking can strengthen the music ther-apy's analgesic effect.
