Nonspecific attention was as effective as an early skill-based intervention in reducing maternal anxiety and enhancing sensitive behavior in mothers of VLBW infants.

ABSTRACT. Objective. To evaluate the consequences of being small-for-gestational age at extremely low gestational age.Methodology. Results. Forty-one (21%) of the 191 infants were classified as SGA. Those with congenital anomalies (10% in the SGA and 2% in the AGA group) were excluded from further analysis. Despite a similar rate of respiratory distress syndrome (50%), the SGA infants had a greater rate of failure of indomethacin treatment for PDA closure (54% vs 32% for AGA), a higher risk for CLD defined as a need for supplementary oxygen at 36 weeks (65% vs 32% for AGA), a more prolonged need for oxygen supplementation and ventilatory support (94 days vs 68 days for AGA and 58 days vs 40 days for AGA, respectively). SGA infants were also at greater risk for developing severe ROP (stage III) (65% vs 12% for AGA).Conclusions. For infants born before 27 weeks, being small-for-gestational age confers additional risks for severe morbidity, ie, PDA ligation, CLD, and ROP. Pediatrics 1997;100(2).

The elimination, disposition and protein binding of ibuprofen (IBU) in premature infants were studied for use in the prevention of intraventricular hemorrhage and closure of patent ductus arteriosus. The kinetic profile of i.v. IBU lysine (10 mg/kg bolus) given within the first 3 h after birth was studied in 21 premature neonates (mean birthweight = 944.7 g, range: 575-1450 g; gestational age: 26.8 weeks, range: 22-31 weeks). Blood samples (0.3 ml/sample) were obtained at time 0 and at 1, 3, 6, 12, 24, 48, and 72 h post-dose for IBU by high-performance liquid chromatography (HPLC). Kinetic analyses assumed applicability of one open-compartment model and calculations from the model-independent areas under the time concentration curve (AUC). Data (mean +/- SEM) show that apparent volume of distribution (AVd) was 62.1 +/- 3.9 ml/kg, plasma t1/2 beta was 30.5 +/- 4.2 h, elimination rate constant (Kel) was 0.032 +/- 0.004 h-1, plasma clearance was 2.06 +/- 0.33 ml/kg/h and plasma concentration (Cp) at 1 h was 180.6 +/- 11.1 mg/l. Gestational age and birthweight were not related to drug elimination. In 10 neonates, IBU maintenance dose of 5 mg/kg once daily on days 2 and 3 generated mean Cp of 116.6 +/- 54.5 mg/l and 113.6 +/- 58.2 mg/l, respectively. Protein binding by ultrafiltration and capillary electrophoresis showed that the percentage bound IBU was significantly lower in full term cord plasma (94.98 +/- 0.39%, n = 26) compared to adult plasma protein (mean +/- SE = 98.73 +/- 0.31%, n = 8, p < 0.0001). Compared to data from adults and older children, IBU elimination is markedly prolonged in neonates and protein binding is slightly lower. Thus, investigational and clinical therapeutic regimens should be adjusted to account for decreased drug disposition to ensure safe and effective therapy.
