Abstract:
Objective:To evaluate the effect of white noise on reducing procedural pain of premature infants.Methods:Randomized controlled trials (RCTs) on the effect of white noise on reducing procedural pain in premature infants were searched for in PubMed, Embase, Web of Science, Cochrane Library, CINAHL, CNKI, VIP, Wanfang database and China Biology Medicine disc. The retrieval time was from the establishment of the databases to January 12, 2023. After independent literature screening, data extraction and bias risk assessment by two researchers, Meta-analysis was conducted using RevMan 5.3 software.Results:A total of 8 RCTs with 689 premature infants were finally included. The Meta-analysis results showed that compared with conventional procedures, the use of white noise alone could reduce the pain score ( SMD=-2.29, 95% CI: -2.78--1.79, P<0.000 01) in preterm infants during and after procedures ( SMD=-2.55, 95% CI: -4.52--0.58, P=0.01) , reduce the heart rate ( MD=-7.38, 95% CI: -7.97--6.80, P<0.000 01) during and after procedures ( MD=-10.36, 95% CI: -13.58--7.14, P<0.000 01) , and increase blood oxygen saturation during operation ( MD=3.78, 95% CI: 3.54-4.02, P<0.000 01) and after operation ( MD=2.19, 95% CI: 1.84-2.54, P<0.000 01) . Conclusions:White noise can effectively relieve the procedural pain of premature infants and maintain the stability of physiological indicators. In the future, more high-quality and large sample randomized controlled trials should be conducted to verify the application effect of white noise in relieving pain of premature infants.
