Introduction: Relieving pain in newborns is one of the main goals of nursing care, and in this context, non-pharmacological methods of pain relief have always been of interest to nurses. The aim of this study is to investigate the effect of non-nutritional sucking and mother's voice on venous blood sampling pain in newborns.
Methods: In this randomized clinical trial, 105 newborns aged 3 to 10 days with neonatal jaundice were selected using the available method. They were randomly divided into three groups including non-nutritional sucking, mother's voice and control groups. The procedure was as follows; during venous blood sampling, video was taken for all three groups, and then the severity of pain during blood sampling was evaluated by reviewing the video and filling in the newborn pain questionnaire. Data analysis was done using SPSS version 26 and chi-square test, Fisher's exact test, Kruskal-Wallis test and Ben Feroni pairwise comparison.
Results: The results showed that the average pain score in the non-nutritional sucking group (3.20 ± 2.33) was significantly lower than the control group (5 ± 2.22) (P = 0.006). But the average pain score in the mother's voice group (4.06 ± 2.49) and the control group (5 ± 2.22) has no significant difference (P = 0.393). Also, the average pain score between the non-nutritional sucking group (3.20 ± 2.33) and the mother's voice group (4.06 ± 2.49) has no statistically significant difference (P = 0.291).
Conclusions: The use of non-nutritive sucking significantly reduced the pain caused by blood sampling in newborns. Of course, considering that there was no difference in the two groups of mother's voice and non-nutritive sucking, mother's voice can also be used in some cases.
