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.

Randomized Controlled Trial Clinical TrialDo cry features reflect pain intensity in preterm neonates? A preliminary study.
The purpose of this study was to investigate if cries from preterm neonates would reflect changes in pain intensity following interventions. The cries from 25 preterm neonates from an original sample of 122 were audiorecorded while the infant was undergoing heelstick during a randomized crossover design testing the efficacy of: pacifier with sucrose or water, or prone position as compared to standard care. ⋯ However, neither cry duration nor fundamental frequency reflected group differences. Further research is needed to determine if cry is a sensitive and valid indicator of pain in preterm infants.

Randomized Controlled Trial Clinical TrialPain-relieving effect of sucrose in newborns during heel prick.
We assessed the effect of sucrose as a pain reliever in a population of newborns when cuddled and comforted during heel prick for diagnosis of phenylketonuria. In addition, the influences of gender, gestational age, postnatal age, ponderal index and behavioural state of the infant before the heel prick were studied, as judged by the neonatal infant pain scale (NIPS) score, on crying time (CT) and subsequent NIPS score. 100 healthy full-term infants were enrolled in this double-blind, randomized controlled trial. Before the heel prick, the newborns, when cuddled by the parent(s), were either given 2 ml 50% sucrose solution or 2 ml sterile water. ⋯ NIPS scores before the heel prick correlated significantly and positively with CT and subsequent NIPS scores in both the sucrose and the placebo groups. Intra-orally administered sucrose given before heel prick can be recommended as a useful pain reliever. Furthermore, the findings indicate that factors calming the newborn and creating low NIPS scores before the procedure can reduce the pain reaction equivalently and additively to sucrose administration.

Randomized Controlled Trial Clinical TrialEffect of repeated doses of sucrose during heel stick procedure in preterm neonates.
The purpose of this randomized clinical trial was to test the efficacy of repeated versus single dose sucrose to decrease pain from routine heel stick procedures in preterm neonates. Infants (n = 48) in the first week of life with a mean gestational age of 31 weeks received 0.05 ml of 24% sucrose solution or sterile water by mouth (1) 2 min prior to actual lancing of the heel; (2) just prior to lancing, and (3) 2 min after lancing. ⋯ The Premature Infant Pain Profile (PIPP) scores were obtained for five 30-second blocks from lancing. Both sucrose groups had lower PIPP scores (single sucrose pain scores, 6.8-8.2, p = 0.07; repeated sucrose pain scores, 5.3-6. 2, p < 0.01) than water (pain scores 7.9-9.1), and in the last block, the repeated dose had lower scores than the single dose (6.2 vs. 8. 2, p < 0.05).

Complications of airway management in very-low-birth-weight infants.
To define the incidence of complications of endotracheal intubation and the factors associated with these complications. ⋯ Subglottic stenosis is an infrequent complication of endotracheal intubation with current airway management of very-low-birth-weight infants. Less severe complications are still common, but they are usually amenable to clinical treatment. Bronchoscopy should be performed selectively only in infants with clinical evidence of airway obstruction after extubation.
