Hospitalized neonates usually undergo different painful procedures. This study sought to test the effects of a familiar auditory stimulus on the physiologic responses to pain of venipuncture among neonates in intensive care unit. The study design is quasi-experimental. The randomized clinical trial study was done on 60 full-term neonates admitted to the neonatal intensive care unit between March 20 to June 20, 2014. The neonates were conveniently selected and randomly allocated to the control and the experimental groups. Recorded maternal voice was played for the neonates in the experimental group from 10 minutes before to 10 minutes after venipuncture while the neonates in the control group received no sound therapy intervention. The participants' physiologic parameters were assessed 10 minutes before, during, and after venipuncture. At baseline, the study groups did not differ significantly regarding the intended physiologic parameters (P > .05). During venipuncture, maternal voice was effective in reducing the neonates' heart rate, respiratory rate, and diastolic blood pressure (P < .05). Maternal voice is effective in reducing some physiologic parameters during and after performing the painful procedure of venipuncture. Nurses are recommended to use familiar sounds to effectively manage neonates' physiologic responses to procedural pain of venipuncture.
住院新生儿通常会接受不同的痛苦操作。本研究旨在测试一种熟悉的听觉刺激对重症监护病房新生儿静脉穿刺疼痛生理反应的影响。研究设计为准实验性。该随机临床试验于2014年3月20日至6月20日对60名入住新生儿重症监护病房的足月儿进行。这些新生儿是方便选取并随机分配到对照组和实验组。在实验组中，从静脉穿刺前10分钟到穿刺后10分钟为新生儿播放录制好的母亲声音，而对照组的新生儿未接受声音疗法干预。在静脉穿刺前10分钟、穿刺期间和穿刺后对参与者的生理参数进行评估。在基线时，研究组在预期的生理参数方面无显著差异（P>.05）。在静脉穿刺期间，母亲的声音能有效降低新生儿的心率、呼吸频率和舒张压（P<.05）。母亲的声音在进行静脉穿刺这一痛苦操作期间及之后能有效降低一些生理参数。建议护士使用熟悉的声音来有效管理新生儿对静脉穿刺操作疼痛的生理反应。
