母亲心音联合话音刺激对NICU早产儿心率及行为状态的影响

Effects of Maternal Heart Sound Combined with Voice Stimulation on Heart Rate and Behavior Status of Premature Infants in NICU

目的探讨母亲心音联合话音刺激与音乐疗法2种听觉刺激方式对NICU早产儿心率及行为状态的影响。方法选取符合纳入排除标准的早产儿90例,按随机化数字表分为对照组、2个干预组(音乐疗法组和母亲声音刺激组),每组各30例。对照组行常规护理,音乐疗法组在常规护理的基础上播放音乐,母亲声音刺激组在常规护理的基础上播放母亲心音联合话音的声音刺激,2次/d,持续14 d。比较3组早产儿在干预前1 min,干预中(10 min、20 min),干预后1 min的心率及行为状态情况。结果(1)组间比较:干预前1 min 3组早产儿心率及行为状态评分差异无统计学意义(P>0.05);干预中(10 min、20 min)和干预后1 min 2个干预组心率及行为状态评分均低于对照组(P<0.05);干预中20 min及干预后1 min母亲声音刺激组心率及行为状态评分显著低于音乐疗法组(P<0.05),但干预中10 min 2个干预组心率及行为状态评分差异无统计学意义(P>0.05),干预后1 min 2个干预组间行为状态差异无统计学意义(P>0.05);(2)组内比较:对照组干预前中后4个时间点间心率及行为状态评分差异无统计学意义(P>0.05),2个干预组于干预中(10 min、20 min)及干预后1 min的心率及行为状态评分显著低于干预前1 min(P<0.05),但母亲声音刺激组干预中20 min与干预后1 min间行为状态评分差异无统计学意义(P>0.05)。结论母亲心音联合话音刺激与音乐疗法相比,能更有效的降低早产儿心率,稳定情绪,促进睡眠,达到最佳行为状态。

Objective To investigate the effects of maternal heart sound combined with voice stimulation and music therapy on heart rate and behavior of premature infants in NICU.Methods Ninety premature infants who met the exclusion criteria were randomly divided into control group,group B(music therapy group)and group C(maternal voice stimulation group),with 30 cases in each group.Control group received routine nursing;group B played music on the basis of routine nursing,and group C played sound stimulation of mother’s heart sound combined with voice on the basis of routine nursing.The intervention performed twice a day for 14 days.Heart rate and behavioral status of premature infants 1min before the intervention,during the intervention(10min,20min)and 1min after the intervention were compared among the three groups.Results(1)inter-group comparison showed there was no significant difference in heart rate and behavior status score of premature infants among the three groups 1min before the intervention(P>0.05)but during the intervention(10min,20min)and 1min after the intervention,the scores of heart rate and behavior state of group B and group C were lower than those in control group(P<0.05).The heart rate and behavioral status score at 20min of the intervention and 1min after the intervention,in group C were significantly lower than those in group B(P<0.05),but there was no significant difference in heart rate and behavioral state score at 10min of the intervention between these two groups(P>0.05).There was no significant difference in behavioral status between these two groups 1 min after the intervention(P>0.05).(2)Intra-group comparison showed that there was no significant difference in heart rate and behavior status score in control group before and after the intervention(P>0.05);during the intervention(10min,20min)and 1min after intervention,heart rate and behavioral status scores in group B and group C were significantly lower than those 1min before the intervention(P<0.05),but there was no significant difference in behavior status score of group C at 20min of the intervention and 1min after the intervention(P>0.05).Conclusion Compared with music therapy,maternal heart sound combined with voice stimulation can effectively reduce the heart rate of premature infants,stabilize mood,promote sleep,and achieve the best behavior state.
