Objective:To evaluate risk factors and impact of delivery room cardiopulmonary resuscitation (DR-CPR) on very low birth weight (VLBW) preterm infants.Study Design:A national, population-based, observational study evaluating risk factors and short-term neonatal outcomes associated with DR-CPR among VLBW, extremely preterm infants (EPIs, 24 to 27 weeks’ gestation) and very preterm infants (VPI, 28 to 31 weeks’ gestation) born in 1995 to 2010.Results:Among 17 564 VLBW infants, 636 (3.6%) required DR-CPR. In the group of 6478 EPI, 412 (6.4%) received DR-CPR compared with 224 of 11 086 infants (2.0%) in the VPI group. EPI who underwent DR-CPR had higher odds ratios (ORs (95% confidence interval)) for mortality compared to EPI not requiring DR-CPR (OR 3.32 (2.58, 4.29)), grades 3 to 4 intraventricular hemorrhage (IVH) (OR 1.59 (1.20, 2.10)) and periventricular leukomalacia (OR 1.81 (1.17, 2.82)). DR-CPR among VPI was associated with higher ORs for mortality (OR 4.99 (3.59, 6.94)), early sepsis (OR 2.07 (1.05, 4.09)), grades 3 to 4 IVH (OR 3.74 (2.55, 5.50)) and grades 3 to 4 retinopathy of prematurity (ROP) (OR 2.53 (1.18, 5.41)) compared to VPI not requiring DR-CPR. Only 11% of infants in the EPI DR-CPR group had favorable outcomes compared with 44% in the VPI DR-CPR group. Significantly higher ORs for mortality, IVH and ROP were found in the VPI compared to the EPI group.Conclusion:Preterm VLBW infants requiring DR-CPR were at increased risk of adverse outcomes compared to those not requiring CPR. This effect was more pronounced in the VPI group.

AbstractIn order to evaluate serum amyloid A as an early diagnostic marker of late-onset sepsis, seventy-nine preterm infants with clinically suspected sepsis and 40 healthy matched controls were assayed for serum amyloid A. In parallel, clinical and biochemical variables that are used to evaluate neonatal sepsis were compared. Forty-two episodes were diagnosed as sepsis. Serum amyloid A levels were elevated in the sepsis group (187.6 ± 78.3 μg/ml), compared with infants who had no sepsis (10.2±8.3 μg/ml) and the control group (6.9 ± 3.3 μg/ml), and were significantly higher in gram-negative compared to gram-positive sepsis (221.8 ± 84.4 μg/ml vs.48.5 ± 22.2 μg/ml). Analysis of the data suggests serum amyloid A has the highest sensitivity (100%), specificity (93%) and positive predictive value (96%) for sepsis among the clinical and biochemical parameters that were tested. In conclusion, serum amyloid A seems to be a reliable early marker for the diagnosis of late-onset sepsis in preterm infants.
