Background: Fever in labour is a rise in the maternal body temperature above the usual range of normal during labour. Many have opined that fever is a normal feature associated with labour, thereby attracting less attention; but it is laden with significant fetal, neonatal and maternal morbidity which it heralds. Objective: To determine the prevalence, associated correlates and complications of fever in labour in the University of Benin Teaching Hospital. Study Design: A case-control study. Methods: Forty-seven parturients with intrapartum pyrexia of 38C obtained once or ≥ 37.5ºC on two occasions 2 hours apart, formed the cases. The control group in 1:1 ratio was the next age-matched parturient whose temperature remained <37.5ºC throughout the course of labour. The association between the socio-demographic variables, obstetric factors, maternal and fetal/neonatal complications and maternal pyrexia in labour was determined. Binary logistic regression analysis was performed to determine the predictors of maternal pyrexia in labour. All data was entered into a proforma and analysis done using the SPSS version 21.0. Level of significance was set at p=0.05 and the absence of a null value (1.00) from the confidence intervals of the odds ratio.
