What maternal temperature is a cause for concern during labor?

A maternal temperature of 38°C (100.4°F) or greater during labor is a cause for concern due to its potential implications for both the mother and the fetus. Elevated maternal temperatures can indicate the presence of infection, which is particularly critical during labor when the risks of complications can increase. Infections such as chorioamnionitis (infection of the amniotic fluid) pose serious risks, including preterm labor, fetal distress, and negative neonatal outcomes.

A maternal fever in this range suggests a need for further evaluation and possibly intervention to manage infection and prevent any detrimental effects on the labor process or the baby's health. The consideration of a maternal temperature threshold of 38°C stands out as a vital marker for healthcare providers to monitor closely during labor for signs of infection or complications that may require prompt medical attention.
