Maternal hypothermia during elective caesarean delivery: A prospective observational study
Authors' conclusion
In the present study almost a third of the women undergoing elective caesarean delivery developed perioperative hypothermia with a core temperature <36.0°C. The mean duration of maternal hypothermia was 77 min, lasting well into the postoperative period for many patients.
Study context
- Population
- Women ≥18 years undergoing elective caesarean delivery under spinal anaesthesia
- Participants
- 40 women
- Outcome
- Incidence and duration of perioperative maternal hypothermia (core temperature <36.0°C)
Methodological detailscontinuous zero-heat-flux core temperature monitoring
- Continuous zero-heat-flux core temperature monitoring
Main finding
As reported in the abstract
Perioperative hypothermia (<36.0°C)
Incidence of perioperative hypothermia
32.5%
Duration of hypothermia (mean ± SD)
77 ± 40 min
Observational data: associations, not effects.
Further findings
Core temperature, hypothermic vs normothermic patients
- Similar at preoperative baseline; significantly lower in hypothermic patients from OR arrival through the remaining study period
Thermal discomfort and shivering on PACU admission
- Thermal discomfort and felt cold
- Forty percent
- Shivering
- 33%
- Neither thermal discomfort nor shivering associated with hypothermia
