This study aimed to investigate the effects of the mother-sung lullaby during vaccine administration on vaccine-induced pain in babies and anxiety in mothers. Two family health centers in Turkey between March 4, 2020, and August 28, 2020. A total of 60 babies who received the Bacille Calmette-Guérin vaccine and their mothers.These babies were randomly assigned to one of two groups, including 30 babies in the lullaby group and 30 babies in the control group. Data on descriptive information for all babies and mothers were collected through face-to-face interviews with the mothers before vaccination. Heart rate, oxygen saturation, and crying duration were measured in all babies. Heart rate and oxygen saturation of the babies were recorded using a pulse oximeter during and after vaccine administration. The crying time, measured for up to 30 seconds after vaccination, was recorded as the total cry time (using video seconds). The pain score was evaluated by two observers using the Neonatal Infant Pain Scale, based on video recordings obtained during and after vaccine administration. In addition, mothers' anxiety scores were measured using the State Anxiety Inventory, both before and after vaccination.
Childhood pain can cause long-term and psychologically harmful effects. Music can reduce pain and anxiety. This study aimed to investigate the effects of the mother-sung lullaby during vaccine administration on vaccine-induced pain in babies and anxiety in mothers.
