“…Further intra-operative hypothermia should be treated with active warming measures in order to shorten the patient's exposure to low core temperature into the postoperative phase. 17 Although baseline temperature was not correlated to later occurrence of hypothermia, the core temperature at arrival in the OR seems to be predictive. Our data suggest that core temperature of 37 C or less, is predictive and may warrant extra measures in order to avoid development of hypothermia.…”

“…8 In most published studies on CD and hypothermia, the temperatures have been measured with methods that do not accurately obtain the patient's core temperature. 5,[14][15][16][17] Further, many studies have not assessed core temperature before arrival in the OR or in the postoperative phase. The emergency caesarean delivery (ECD) patients have sometimes been mixed with elective CD procedures, although the two groups have different physiological situations and different temperature profiles.…”

“…18 Also, significant bias factors in previous studies on hypothermia prevention in CD patients were detected in a recent published meta-analysis. 17 To our knowledge, no previous studies have investigated the incidence and duration of hypothermia in women undergoing elective CD in a prospective clinical study using a high accuracy continuous temperature monitoring system through the full perioperative course.…”

BackgroundPatients undergoing caesarean delivery are at risk of developing unintended perioperative hypothermia, defined as a core temperature <36.0°C. Most previous studies of core temperature in caesarean delivery patients have not been conducted with accurate measurements for the complete perioperative period. Therefore, we conducted a prospective observational study to identify the incidence and duration of pre‐ and post‐operative maternal hypothermia with a high accuracy continuous temperature monitoring system.MethodsWomen ≥18 years old presenting for elective caesarean delivery under spinal anaesthesia were invited to participate in the study. The primary outcomes were the incidence and duration of perioperative maternal hypothermia (<36.0°C). Maternal core temperatures were measured with the non‐invasive zero‐heat‐flux thermometer (Bair Hugger Temperature Monitoring System, 3M) throughout the perioperative course.ResultsA total of 40 participants were recruited to the study. The incidence of perioperative hypothermia was 32.5%, with a duration of 77 ± 40 min (mean ± standard deviation). The hypothermic patients had similar core temperature as the normothermic patients at baseline preoperatively, but significantly lower temperature at operating room arrival and during the remaining study period. Forty percent of all patients reported thermal discomfort and felt cold on admission to post anaesthesia care unit, whereas 33% had shivering. Neither thermal discomfort nor shivering were associated with hypothermia.ConclusionIn 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. These data should remind healthcare professionals of the importance of measuring core temperature in all phases of the perioperative setting and to consider optimal warming measures to avoid and treat hypothermia.
