The Effects of Auditory Interventions on Comfort and Mothers' Anxiety in Newborns

The heel blood procedure for newborn screening is done for almost all babies within the first 48 hours of birth. It is stated that non-pharmacological methods in reducing pain during the heel blood collection process are simple, effective, free, and very cost-effective. Studies have shown that auditory interventions (such as mother's voice, white noise) used in invasive procedures distract the infant and create a cognitive strategy for pain control. According to this information, one aim of the study is to determine the effect of the mother's voice and white noise, which are non-pharmacological methods, on the comfort level of the baby in the heel blood procedure. It is thought that especially acute painful procedures applied to infants will reduce the level of stress and anxiety in parents. Another aim of this study is to determine the effect of a mother's voice and white noise, which are non-pharmacological methods, on the state anxiety levels of mothers in the heel blood collection process.

The heel blood procedure for newborn screening is done for almost all babies within the first 48 hours of birth. The heel blood procedure, which is widely used for the diagnosis and follow-up of various diseases, causes acute pain in infants. It is stated that non-pharmacological methods in reducing pain during the heel blood collection process are simple, effective, free, and very cost-effective. For example, non-pharmacological methods such as breastfeeding, skin-to-skin contact, oral sucrose, mother's voice, and white noise are stated to be effective in reducing acute pain. Clinical practice guidelines recommend the use of non-pharmacological methods in acute painful procedures. Studies have shown that auditory interventions (such as mother's voice, white noise) used in invasive procedures distract the infant and create a cognitive strategy for pain control. According to this information, one aim of the study is to determine the effect of the mother's voice and white noise, which are non-pharmacological methods, on the comfort level of the baby in the heel blood procedure.

Few studies have targeted parents of newborn infants, although studies to date have shown that parents want to be more involved in their infants' pain management. Parents reported that they wanted to learn more about pain management strategies, they wanted to play a role in the relaxation of their babies, and they hoped for more opportunities to participate in the care of their babies in the hospital. It is thought that especially acute painful procedures applied to infants will reduce the level of stress and anxiety in parents. In addition, one study reported that when parents are given information to help reduce their baby's pain, they accept painful procedures such as heel prick more easily and feel calmer. In the light of this information, another aim of this study is to determine the effect of a mother's voice and white noise, which are non-pharmacological methods, on the state anxiety levels of mothers in the heel blood collection process.
