ABSTRACT
OBJECTIVE:
To determine the influence of routine intrapartum amnioinfusion (AI) on intrauterine temperature.DESIGN:
Prospective observational study.SETTING:
Maternity unit, Barnes Jewish Hospital, St Louis, MO, USA. SAMPLE Forty women with singleton gestations and an indication for intrapartum intrauterine pressure catheter placement.METHODS:
Using a temperature probe, we digitally recorded intrauterine temperature every 10 minutes during labour. Amnioinfusion was administered according to a standard protocol using saline equilibrated to the ambient temperature. MAIN OUTCOMEMEASURE:
Mean intrauterine temperature during labour.RESULTS:
Participants were monitored for a mean of 280 minutes (range 20-820). A total of 164 intrauterine temperature readings in the AI cohort were compared with 797 control measurements. When compared with controls, we observed a lower intrauterine temperature in the AI cohort (36.4 versus 37.4°C, P<0.01). More measurements in the AI cohort were recorded in the presence of intrapartum fever (40% versus 30%). A subgroup analysis of measurements recorded in afebrile parturients revealed an even greater effect of AI (1.5°C decrease, 37.3 versus 35.8°C, P<0.01).CONCLUSION:
Routine intrapartum AI using saline equilibrated to a mean ambient temperature of 25.0°C reduces intrauterine temperature and may thereby affect fetal core temperature.
