Excerpt: In their recent study [ 1 ], Lavesson et al. concluded, “In febrile parturients, neither maternal nor fetal temperatures dropped after paracetamol, but paracetamol halted an increasing trend and stabilized the fetal temperature. The effect of paracetamol on maternal temperature was inconclusive”. This conclusion, however, is not supported by the data in the study, in that the calculation of case and control temperature differences demonstrates clear fetal and maternal temperature decreases after paracetamol.
