“…Intrapartum fever, usually defined as a temperature ≥ 38°C, might be a result of maternal or fetal infection, particularly chorioamnionitis; an increased metabolic rate; or the use of epidural analgesia . Some investigators suggest that in the vast majority of patients, the aetiology for intrapartum fever is non‐infectious, particularly when resulting from epidural analgesia …”

Background: Subfebrile intrapartum maternal temperature is very common, yet there is sparse evidence regarding its causes or its effects on perinatal outcomes. We examined whether mild temperature elevation during labour is a risk marker for adverse obstetric and neonatal outcomes. Methods: A retrospective cohort analysis including 42 601 term, singleton live-births in two medical centres between 2003 and 2010 was performed. This study compared women who experienced a maximal intrapartum temperature of ≤37°C with women who experienced subfebrile intrapartum temperature (37.1-37.9°C). Adjusted risks for adverse obstetric and neonatal outcomes were calculated by using multivariable logistic regression models. Results: Compared with maternal temperature ≤ 37°C, subfebrile temperature was associated with higher rates of primary caesarean deliveries {adjusted odds ratios . Mildly elevated maternal intrapartum temperature (37.1-37.5°C) was also associated with adverse outcomes. Conclusions: Maternal intrapartum subfebrile temperature may be an indicator of operative delivery and neonatal morbidity. Further research is needed to confirm these findings and to reveal underlying mechanisms.

“…The maternal body temperature increases during labor and the increase is greater in primiparae than in multiparae (1,2). The fetus has a 0.24 °C higher temperature than the mother when measured as fetal skin and maternal uterine wall temperatures (3,4).…”

Running foot: Effect of paracetamol on temperature in labour Wilcoxon matched-pairs signed-ranks test and cross-sectional data with Mann-Whitney U test. Shapes of the temperature curves were compared with mixed-effect models statistics for repeated measurements. The main outcome measures were temperature changes after paracetamol. A two-tailed P <0.05 was considered significant. RESULTS:Prior to T0 maternal and fetal temperatures increased in the paracetamol group, but after T0 no significant changes (P ≥0.1) were seen when compared with Wilcoxon signedranks test. In the control group, both temperatures increased from T-60 and onwards. Deltatemperatures (fetal minus maternal temperature) remained unchanged in both groups. The mixed-effect models analyses showed a significant difference (P =0.01) in the shape of fetal temperature curves between the paracetamol and control groups, but no significant difference (P =0.4) in maternal temperature curve shapes.

“…Labouring parturients have been reported to have both thermoregulatory and non-thermoregulatory shivering, with and without epidural analgesia. 16 Despite normal increases in temperature during labour 17 and with epidural analgesia, 18 shivering can still occur and its mechanism may be different from thermoregulatory shivering. 1 In addition, labouring patients are often exposed to epidural analgesia and its effects on thermoregulation and shivering for hours prior to CD.…”
