Inhaled nitric oxide therapy improves the pulmonary outcome for premature infants who are at risk for bronchopulmonary dysplasia when it is started between 7 and 21 days of age and has no apparent short-term adverse effects. (ClinicalTrials.gov number, NCT00000548 [ClinicalTrials.gov] .).

Ventilator-associated pneumonia (VAP) is a serious complication related to mechanical ventilation in the neonatal period. However, lack of a specific definition and difficulties obtaining noncontaminated samples of the lower respiratory airway render microbiological diagnosis and etiological treatment extremely difficult. Thus far, only few studies have approached VAP using accepted Centers for Disease Control and Prevention criteria and reliable sampling techniques. In recent years, however, the blind-protected bronchoalveolar lavage technique with protected specimen brush and the development of validated biomarkers have attempted to overcome the diagnostic difficulties and assess the response to therapy. This updated review on neonatal VAP aims to stimulate neonatologists' interest in this subtle but serious complication of mechanical ventilation.

The purpose of this study was to determine an association between packed red blood cell (PRBC) transfusions for anemia and necrotizing enterocolitis (NEC) in a subset of stable, growing, premature neonates. As part of a survey of current clinical practices over a 17-month period from June 1999 to October 2000, a chart review was performed to determine the relationship between elective PRBC transfusions and the occurrence of NEC. Demographic data were tabulated and compared between the NEC patients with a prior history of immediate blood transfusion (within 48 hours of onset of symptoms) and those NEC patients without a prior history of immediate blood transfusion. A total of 908 (inborn) neonatal admissions had received 751 PRBC transfusions during the study period; of these, 17 patients (1.8%) had developed radiographic, clinical, or surgical signs of NEC. Six cases of NEC (35%; six of 17 patients) were associated with PRBC transfusions (0.8%; six of 751 transfusions). The transfusion-associated NEC group developed presenting signs within 22 +/- 5 hours (median, 19; range, 12 to 38) of a PRBC transfusion at a mean age of 32 +/- 7 days. In contrast, the non-transfusion-associated NEC group (n = 11) had onset of NEC at a mean age of 12 +/- 7 days ( P < 0.05) after 185 +/- 91 hours (median, 180; range, 96 to 312; P < 0.02] of a transfusion. Prior to the onset of NEC, all of the neonates in the transfusion-associated NEC group were stable, growing, not ventilated, receiving full enteral feedings, and had no other active medical problems except anemia (hematocrit, 24 +/- 3%). In contrast, the nontransfusion NEC group was more often ventilated, was receiving < 50% of fluids by mouth, had lower Apgar scores, and was transfused for an average hematocrit of 37 +/- 7% ( P < 0.05). There was no significant difference in the type, storage, volume, or preservative used between the blood products in the two groups. We identified an unanticipated relationship between late-onset NEC in stable, growing, premature neonates who were transfused electively for anemia of prematurity.

Oxygen is a neonatal health hazard that should be avoided in clinical practice. In this review, an international team of neonatologists and nurses assessed oxygen saturation (SpO2) targeting in preterm infants and evaluated the potential weaknesses of randomised clinical trials.ConclusionSpO2 of 85–89% can increase mortality and 91–95% can cause hyperoxia and ill effects. Neither of these ranges can be recommended, and wider intermediate targets, such as 87–94% or 88–94%, may be safer.

Background-Transiently low levels of thyroid hormones occur in ∼50% of neonates born 24-28 weeks' gestation and are associated with higher rates of cerebral palsy and cognitive impairment. Raising hormone levels shows promise for improving neurodevelopmental outcome.

Cord blood IL-6 showed superior LR than CRP; therefore, it is a better predictor to initiate treatment in neonates with prenatal infectious risk factors immediately after birth.

"Proactive" management of PICC, significantly reduced the incidence of CRIs. The reduction in infection rate is estimated to save 180 hospitalized patient days/100 very low birth weight neonates, with a concomitant savings in morbidity and medical expense.
