Abstract/OtherAbstract:
Objective. To evaluate the added value of the baseline T/QRS ratio to other known risk factors in predicting adverse outcome and interventions for suspected fetal distress. Design. Prospective cohort study. Setting. Three academic and six non-academic teaching hospitals in the Netherlands. Population. Laboring women with a high-risk cephalic singleton pregnancy beyond 36 weeks of gestation. Methods. We obtained STAN(®-) recordings (ST-analysis, Neoventa, Sweden) from two previous studies. Three patient groups were defined: cases with adverse outcome, cases with emergency delivery because of suspected fetal distress without adverse outcome and a reference group of uncomplicated cases. Baseline T/QRS ratios among the adverse outcome and intervention for suspected fetal distress cases were compared to the uncomplicated cases. The ability for baseline T/QRS to predict adverse outcome and suspected fetal distress was determined using a multivariable logistic model. Main outcome measures. The added value of the baseline T/QRS to other known risk factors in the prediction of adverse outcome and interventions for suspected fetal distress. Results. From 3 462 recordings 2 459 were available for analysis. Median baseline T/QRS for uncomplicated cases, adverse outcome and interventions for suspected fetal distress were 0.12 (range 0.00-0.52), 0.12 (0.00-0.42) and 0.13 (0.00-0.39), respectively. There was no statistical difference between these groups. Multivariable analysis showed no added value of baseline T/QRS in the prediction of adverse outcome or in the prediction of interventions for suspected fetal distress. Conclusion. Baseline T/QRS has no added value in the prediction of adverse neonatal outcome or interventions for suspected fetal distress.
