Randomized Controlled Trial Clinical TrialSensorial saturation: an effective analgesic tool for heel-prick in preterm infants: a prospective randomized trial.
Pain is traumatic for preterm infants and can damage their CNS. We wanted to assess whether multisensorial stimulation can be analgesic and whether this effect is only due to oral glucose or sucking. We performed a randomized prospective study, using a validated acute pain rating scale to assess pain during heel-prick combined with five different procedures: (A) control, (B) 10% oral glucose plus sucking, (C) sensorial saturation (SS), (D) oral water, and (E) 10% oral glucose. ⋯ SS and sucking plus oral glucose have the greater analgesic effect with respect to no intervention (p < 0.001). The effect of SS is statistically better than that of glucose plus sucking (p < 0.01). SS promotes interaction between nurse and infant and is a simple effective form of analgesia for the NICU.

Randomized Controlled Trial Clinical TrialBrain hemodynamic changes in preterm infants after maintenance dose caffeine and aminophylline treatment.
To investigate the acute effects of low-dose caffeine and aminophylline on cerebral blood flow in preterm infants, using both near-infrared spectroscopy (NIRS) and cerebral Doppler ultrasonography. ⋯ Caffeine does not significantly affect brain hemodynamics, while aminophylline induces a significant transient increase in O(2)Hb and HHb concentration and CBV.

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.
