Randomized Controlled Trial Clinical TrialNonnutritive sucking during heelstick procedures decreases behavioral distress in the newborn infant.
We investigated if nonnutritive sucking (NNS) during heelstick procedures alleviates behavioral distress in neonates. In our NICU, 26 neonates without severe complications (mean Minde score 0.8, range 0-3), undergoing heelstick procedures at least twice a day, in the first 2 weeks of life, were enrolled in the trial (mean gestational age 33.9 weeks, range 26-39 weeks, mean birth weight 1, 988.5 g, range 1,200-4,010 g, mean Apgar score at the first minute 6. 7, range 4-10, at the fifth minute 8.5, range 6-10). Two heelpricks were performed in each neonate with NNS randomly assigned. ⋯ Nonnutritive sucking had no effect on respiratory rate or transcutaneous oxygen tension, but reduced the time of crying and the heart rate increase during the procedure. In conclusion, NNS can be recommended to reduce distress in newborns undergoing invasive routine procedures. Further studies are needed to evaluate the effects of NNS on respiratory rate and blood gas levels.
