母亲声音刺激对缓解住院新生儿操作性疼痛的效果观察

目的 探讨母亲声音刺激对于新生儿足跟采血操作性疼痛的影响。方法 将72名新生儿监护室住院新生儿随机分成干预组（n=35）和对照组（n=37）。对照组实施常规的足跟采血操作，干预组在常规操作的基础上于操作前1 min至操作结束播放预先录制的母亲声音。记录两组新生儿穿刺前后的疼痛评分、啼哭发生和生命体征变化情况。结果 与对照组比较，干预组新生儿穿刺过程中的心率显著降低，血氧饱和度显著增高，哭闹发生率和疼痛评分显著降低（P < 0.05）。结论 母亲声音刺激有利于减少新生儿操作性疼痛，保持生命体征稳定。

Clinical effect of maternal voice stimulation in alleviating procedural pain in hospitalized neonates

Objective To study the clinical effect of maternal voice stimulation in alleviating procedural pain in neonates during heel blood collection. Methods A total of 72 neonates who were admitted to the neonate intensive care unit were randomly divided into an intervention group (n=35) and a control group (n=37). Heel blood collection was performed by the routine method in the control group. The intervention group listened to their mothers' voice from 1 minute before heel blood collection to the end of the procedure. Pain score, incidence of crying, and vital signs were recorded before and after heel blood collection. Results Compared with the control group, the heart rate was significantly reduced, the blood oxygen saturation significantly increased, the incidence of crying and the pain score were significantly reduced in the intervention group during the procedure of heel blood collection (P < 0.05). Conclusions Maternal voice stimulation helps to reduce procedural pain and maintain stable vital signs in neonates.
