Evaluation of Methods to Minimize Pain in Newborns during Capillary Blood Sampling for Screening: A Randomized Clinical Trial

This study did not answer the question of which pain management method used during the heel prick was statistically more effective in reducing pain. However, the results indicate that each of the non-pharmacological interventions (breastfeeding, oral glucose dosing and non-nutritive sucking) applied during heel puncture resulted in effective pain management in most of the newborns enrolled in the study. The relationship between heart rate variability and the severity of pain was confirmed. Mothers of newborns in the breastfeeding group were satisfied with the pain relief methods used in the child and the opportunity to console their newborn during painful procedures in a technologically invasive environment.
