614: Does NICHD category II fetal heart rate tracing in the 30 minutes prior to deliery predict fetal acidosis in preterm infants?Objective We sought to determine the ability of NICHD fetal heart rate (FHR) tracing categories to predict fetal acidosis in preterm infants during the 30 minutes ...
Conclusion The overwhelming majority of the tracings (79%) were category II. There is moderate agreement in the interpretation of fetal heart rate categories using the NICHD "Three-Tier Fetal Heart Rate Interpretation System". The clinical value (predictive ability) of this new classification should...
Initial analyses stratified these women according to the timing of diagnosis [before (Group1: n=262) or during pregnancy (Group2: n=330)]. At baseline: CDC Clinical Category A (Group1=85%; Group2=92%, p=0.003); mean (卤SD) CD4+ count [Group1=404 (206), Group2=457 (228), p=...
The resulting Kappa statistics showed good agr eement for Category 1, poor for Category 2, and moderate for Category 3. ( Table ) Overall agreement was moderate. Interestingly, 5 tracings showed excellent agreement (kappa > 0.75) and 4 showed poor agreement (kappa < 0.35). We found a ...
