Randomized Controlled Trial Multicenter Study Clinical Trial
Reduction in red blood cell transfusions among preterm infants: results of a randomized trial with an in-line blood gas and chemistry monitor.
Critically ill, extremely premature infants develop anemia because of intensive laboratory blood testing and undergo multiple red blood cell (RBC) transfusions in the early weeks of life. To date, researchers have had only limited success in finding ways to reduce transfusions significantly in this patient population. ⋯ As long as an umbilical artery catheter is available for blood sampling with an in-line blood gas and chemistry monitor, significant reductions in neonatal RBC transfusions can be achieved. The patients most likely to benefit from monitor use are the smallest, most critically ill newborns.

Randomized Controlled Trial Clinical Trial
Morphine, hypotension, and adverse outcomes among preterm neonates: who's to blame? Secondary results from the NEOPAIN trial.
Hypotension occurs commonly among preterm neonates, but its cause and consequences remain unclear. Secondary data analyses from the NEOPAIN trial identified the clinical factors associated with hypotension and examined the contributions of morphine treatment or hypotension to severe intraventricular hemorrhage (IVH) (grades 3 and 4), any IVH (grades 1-4), or death. ⋯ Preemptive morphine infusions, additional morphine, and lower gestational age were associated with hypotension among preterm neonates. Severe IVH, any IVH, and death were associated with preexisting hypotension, but morphine therapy did not contribute to these outcomes. Morphine infusions, although they cause hypotension, can be used safely for most preterm neonates but should be used cautiously for 23- to 26-week neonates and those with preexisting hypotension.

Randomized Controlled Trial Clinical Trial
The role of endogenous opioids in mediating pain reduction by orally administered glucose among newborns.
It has been demonstrated clearly that sweet-tasting solutions given before a painful intervention can reduce pain among newborns. There is no fully accepted explanation for this effect, but activation of endogenous opioids has been suggested as a possible mechanism. The aim of this study was to obtain deeper knowledge of the underlying mechanism by investigating whether administration of an opioid antagonist would reduce the effect of orally administered glucose at heel stick among term newborns. ⋯ Administration of an opioid antagonist did not decrease the analgesic effect of orally administered glucose given before blood sampling.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A multicenter, randomized, masked, comparison trial of lucinactant, colfosceril palmitate, and beractant for the prevention of respiratory distress syndrome among very preterm infants.
Evidence suggests that synthetic surfactants consisting solely of phospholipids can be improved through the addition of peptides, such as sinapultide, that mimic the action of human surfactant protein-B (SP-B). A synthetic surfactant containing a mimic of SP-B may also reduce the potential risks associated with the use of animal-derived products. Our objective was to compare the efficacy and safety of a novel synthetic surfactant containing a functional SP-B mimic (lucinactant; Discovery Laboratories, Doylestown, PA) with those of a non-protein-containing synthetic surfactant (colfosceril palmitate; GlaxoSmithKline, Brentford, United Kingdom) and a bovine-derived surfactant (beractant; Abbott Laboratories, Abbott Park, IL) in the prevention of neonatal respiratory distress syndrome (RDS) and RDS-related death. ⋯ Lucinactant is a more effective surfactant preparation than colfosceril palmitate for the prevention of RDS. In addition, lucinactant reduces the incidence of BPD, compared with colfosceril palmitate, and decreases RDS-related mortality rates, compared with beractant. Therefore, we conclude that lucinactant, the first of a new class of surfactants containing a functional protein analog of SP-B, is an effective therapeutic option for preterm infants at risk for RDS.

Randomized Controlled Trial Clinical Trial
Rapid, needle-free delivery of lidocaine for reducing the pain of venipuncture among pediatric subjects.
The purpose of this study was to determine the optimal configuration of an investigational, single-use, needle-free, drug system (ALGRX 3268) that delivers powdered lidocaine into the epidermis for the rapid production of local anesthesia among pediatric subjects undergoing venipuncture. ⋯ Both active configurations were safe and well tolerated by pediatric subjects undergoing venipuncture at the antecubital fossa. ALGRX 3268 at 0.5 mg, administered 2 to 3 minutes before venipuncture, produced significantly lower pain scores, compared with placebo.
