Comparative Study
Nitric oxide inhalation therapy in very low-birthweight infants with hypoplastic lung due to oligohydramnios.
Although nitric oxide inhalation (iNO) therapy improves arterial oxygenation and reduces the rate of extracorporeal membrane oxygenation in term neonates, the efficacy of this therapy in premature infants is controversial. The objective of the present study was to determine whether iNO therapy improves the survival of very low-birthweight infants with pulmonary hypoplasia due to prolonged rupture of membrane. ⋯ The majority of the infants with pulmonary hypoplasia due to oligohydramnios had persistent pulmonary hypertension. iNO improved the arterial oxygenation and significantly improved the survival rate. A controlled study to determine whether iNO therapy improves the survival rate of preterm infants with pulmonary hypoplasia due to oligohydramnios is necessary.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of ibuprofen and indomethacin therapy for patent ductus arteriosus in preterm infants.
Patent ductus arteriosus (PDA) is commonly found in very low-birthweight (VLBW) infants. The presence of respiratory distress syndrome (RDS) is also associated with increased frequency of significant PDA. Intravenous indomethacin has been used to treat and to prevent PDA in premature infants since 1976. However, concern remains regarding the safety of indomethacin, which affects renal, gastrointestinal and cerebral perfusion. Intravenous ibuprofen has recently been used to treat and to prevent PDA premature infants with PDA without reducing cerebral blood flow or affecting intestinal or renal hemodynamics. The aim of the present study is to compare intravenous ibuprofen and indomethacin with regard to efficacy and safety for the early treatment of PDA in preterm infants. ⋯ Ibuprofen therapy is as efficacious as indomethacin for the treatment of PDA in preterm infants. Infants treated with ibuprofen have higher creatinine clearance and urine output and lower serum creatinine and BUN values than infants treated with indomethacin.

In the neonatal intensive care unit (NICU), hemodynamics in very low-birthweight infants are generally examined for oxygen saturation (SpO2), heart rate, respiration rate, and blood pressure. The present study examined how changes in cerebral circulation in preterm infants can be evaluated by the SpO2 monitoring method with near infrared spectroscopy (NIRS) to detect the cerebral circulation. ⋯ Reduction in SpO2 (<85%) was suggested to be an effective indication to changes in cerebral circulation. In the case of apneic attacks where SpO2 was < or =85%, the cerebral circulation in preterm low-birthweight neonates was extensively changed and, therefore, attention should be paid to changes in the concentration of SpO2 when managing apnea of prematurity in NICU.

There are various identifiable diseases or conditions that can be associated with an apparent life-threatening event (ALTE) in infancy. The present study was carried out to investigate the etiology of ALTE based on the discharge diagnoses. ⋯ It is important to recognize that gastroesophageal impairments such as GERD or CGV could be responsible for many incidences of ALTE in infancy. The authors recommend a trial be established to investigate the causes of ALTE, including gastroesophageal evaluations in all infants with ALTE.

Comparative Study
Early head cooling in newborn piglets is neuroprotective even in the absence of profound systemic hypothermia.
Selective head cooling in the newborn infant has been proposed as a neuroprotective treatment with a lower level of systemic adverse effect than that of systemic hypothermia. However, the efficacy is not confirmed as well as that of systemic hypothermia. In order to analyze the safety and efficacy of selective head cooling, 25 newborn piglets were randomly selected for either normothermic or hypothermic treatment. ⋯ We have demonstrated that early head cooling was effective in preventing some of the earliest brain damage due to hypoxic insult even in the absence of profound systemic hypothermia.
