Fluorescence in situ hybridization and chromosome studies after transfusion in newborns: is a waiting period necessary?

Background: Delaying chromosome studies after transfusion is common practice in many neonatal intensive care units (NICUs). Yet, no evidence exists to support this practice.

Purpose: To investigate the effects of filtration and irradiation on chromosome detection, and to evaluate donor chromosome interference after transfusion.

Inhaled nitric oxide in the treatment of moderate persistent pulmonary hypertension of the newborn: a randomized controlled, multicenter trial.

Objective: Inhaled nitric oxide (iNO) improves oxygenation and reduces the need for extracorporeal membrane oxygenation in infants with severe persistent pulmonary hypertension of the newborn (PPHN). The effectiveness of iNO in the treatment of moderate PPHN has not been adequately defined. We therefore conducted a randomized, prospective multicenter study to assess whether iNO in patients with moderate PPHN would improve arterial p(a)O(2), prevent progression to severe PPHN, and improve outcomes.

Distal ileostomy drip feedings in neonates with short bowel syndrome.

When a newborn infant presents with high intestinal atresia, the proximal segment of the bowel is usually grossly distended and atonic. The anastomosis of this segment to the smaller and unused distal segment will usually result in little or no propulsion of contents distally. Many techniques have been employed to correct this problem.

The role of RBC transfusion in the premature infant.

Fifty-six premature infants with a mean gestational age at birth of 30 weeks were randomly assigned to a transfusion group, for whom the hemoglobin level was kept above 10.0 g/dL, and a nontransfusion group, who were transfused only for specific clinical indications. The groups were followed up longitudinally with weekly determinations of reticulocyte count, the partial pressure of oxygen at which 50% of hemoglobin is saturated, and hemoglobin F percentage, as well as weight gain, length of stay, hospital cost, and frequency and severity of apnea.
