Objective To investigate the association between maternal intrapartum fever and ST-waveform changes of the fetal electrocardiogram. Design Retrospective cohort study. Setting Three academic and six non-academic teaching hospitals in the Netherlands. Population Labouring women with a high-risk singleton pregnancy in cephalic position beyond 36 weeks of gestation. Methods We studied 142 women with fever (≥yen;38.0°C) during labour and 141 women with normal temperature who had been included in two previous studies. In both groups, we counted the number and type of ST-events and classified them as significant (intervention needed) or not significant, based on STAN® clinical guidelines. Main outcome measures Number and type of ST-events. Results Both univariable and multivariable regression analysis showed no association between the presence of maternal intrapartum fever and the number or type of ST-events. Conclusions Maternal intrapartum fever is not associated with ST-segment changes of the fetal electrocardiogram. Interpretation of ST-changes in labouring women with fever should therefore not differ from other situations.
