Predictive value of the neutrophil-to-lymphocyte ratio for epidural labor analgesia-associated intrapartum fever: a retrospective single-center study.

Background: Studies have indicated that epidural analgesia increases the risk of maternal fever during labor, possibly due to non-infectious inflammation. The neutrophil-to-lymphocyte ratio (NLR) is a crucial indicator of inflammation, with a higher NLR potentially signaling worse patient adverse outcomes. The present study explores whether NLR has clinical predictive value for epidural analgesia-related maternal fever (ERMF).
