White Noise and Crying Duration After Invasive Procedures in Infants

The Effect of White Noise on Crying Duration After Invasive Procedures in Infants Aged 1-3 Months

The aim of this study is to evaluate the effect of white noise applied during invasive procedures (blood sampling or intravenous access) on pain and physical parameters in infants aged 1-3 months.

White noise is a monotonous sound that mimics the intrauterine environment, protecting the baby from environmental noise and having a calming effect. The findings may demonstrate the effectiveness of white noise among non-pharmacological approaches to pain management in infants and may offer healthcare professionals an applicable intervention method. If the pain and stress-reducing effects of white noise are proven, its use in routine care could be expanded. There are no known side effects associated with white noise application. There is no risk beyond that of a normal blood draw during the procedure.
