Abstract 【Abstract】 Objective To investigate the effect of white noise on relieving operational pain by fundus screening in premature infants. Methods From March to September 2018, 296 premature infants (gestational age 28-34 weeks, birth weight 1 160-2 000 g) were admitted to NICU, Bayi Children's Hospital, The Seventh Medical Center, General Hospital of PLA, who were performed fundus screening at the age of 4-6 weeks. The infants were given normal position and smoothing method and randomly divided as white noise intervention group (146 cases) and control group (150 cases). The white noise was played in a loop with player while the 146 cases were screening. Premature pain scale (PIPP), heart rate and oxygen saturation were compared between two groups in pre-screening at 5 minute, screening and post-screening at 5 minute. The statistical analysis was carried out by t-test and χ2 test. Results There were no statistical significance in PIPP, heart rate and oxygen saturation between two groups at 5 minutes before screening（P>0.05）. The white noise intervention group was lower than control group in PIPP ［（8.23±0.67）vs（14.72±1.12）points ］ ［(6.12±0.78) vs (10.87±0.93) points, P<0.05］ at 1-5 minutes afterscreening. The heart rate in white noise intervention group ［(152.32±3.28) vs (159.72±1.58) times/min］ was lower than that in control group ［(149.98±4.76) vs (155.87±1.97) times/min, P<0.05］significantly. The oxygen saturation in white noise intervention group ［(87.73±1.57) % vs (83.92±1.32)%］ was higher than that in control group［(88.32±2.28) % vs (86.17±1.83) %, P<0.05］. Conclusions White noise is simple, cheap and non-invasive. It can effectively alleviate the operational pain by the fundus screening for premature infants and can be widely used in clinic.
