Mg. Corbo et al., Nonnutritive sucking during heelstick procedures decreases behavioral distress in the newborn infant, BIOL NEONAT, 77(3), 2000, pp. 162-167
We investigated if nonnutritive sucking (NNS) during heelstick procedures a
lleviates behavioral distress in neonates. in our NICU, 26 neonates without
severe complications (mean Minde score 0.8, range 0-3), undergoing heelsti
ck procedures at least twice a day, in the first 2 weeks of life, were enro
lled 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 heelpric
ks were performed in each neonate with NNS randomly assigned. Behavioral st
ates, transcutaneous oxygen tension (TcPO2), heart rate, and respiratory ra
te were monitored before, during and after the heelstick procedures. Heelst
ick procedures lasted for a mean of 109 s (range 50-230 s) with NNS, and a
mean of 128.8 s (range 20-420 a) without NNS. Compared with baseline, heart
rate and behavioral distress increased and respiratory rate decreased duri
ng heelstick and after heelstick. Oxygen tension did not change. Nonnutriti
ve sucking had no effect on respiratory rate or transcutaneous oxygen tensi
on, but reduced the time of crying and the heart rate increase during the p
rocedure. In con elusion, NNS can be recommended to reduce distress in newb
orns undergoing invasive routine procedures. Further studies are needed to
evaluate the effects of NNS on respiratory rate and blood gas levels. Copyr
