Better epidural pain control linked to higher labor fever odds

A multicentre prospective observational study of 952 nulliparous women receiving epidural labour analgesia found that intrapartum hyperthermia (≥38°C) occurred in 13% of participants. Lower pain intensity scores during labour were associated with significantly higher odds of hyperthermia across multiple pain measures, with the strongest association seen below specific pain score thresholds. The authors suggest extensive sympathetic blockade may promote maternal hyperthermia.

Most relevant for: Nulliparous women receiving epidural labour analgesia for vaginal delivery.
