“…Although data from small patient populations in different settings should be compared with caution, it may be that Our hypothermia incidence is three times higher than reported in the observational multicentre study by Thorburn and colleagues involving 265 participants undergoing emergency CD. 18 This study reported an incidence of hypothermia (<36.0 C) in 10.7% of the patients. However, they also reported that 14.7% of the patients were hyperthermic (>37.5 C) on admission to the recovery room.…”

“…The maternal temperature comfort score was neutral (neither warm or cold, i.e., score of 45-54) in 55% (n = 22) of the patients preoperatively and 30% (n = 12) postoperatively, whereas 17.5% (n = 7) and 40% (n = 16) felt cold in the preoperative and postoperative phase, respectively (Table 3). Eight patients reported to feel warm, that is, a thermal comfort score more than 74, however, none had hyperthermia, defined as a core temperature above 37.5 C. 18 Of the 13 patients (32.5%) who had shivering, only six (15% of total) had hypothermia (Table 1). In the PACU, three patients with shivering were treated with warming devices, two with FAW and one with a warm blanket.…”

“…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.

Purpose Combined spinal-epidural analgesia (CSEA) is effective but not sufficient for labor pain. This study was conducted to assess the real-time analgesic efficacy, side effects of anesthetic drug dosage, and maternal satisfaction in labor to provide reference for the optimization of labor analgesia. Methods This was a prospective, cohort, single-center study that included 3020 women who received CSEA for labor analgesia. The visual analogue scale (VAS) for labor pain, real-time anesthetic drug dosage, side effects, adverse labor outcomes, factors influencing average drug dosage, and maternal satisfaction with CSEA were assessed. Results Overall, the VAS labor pain score was lowest at the first hour after the anesthesia was given. After 4 h for primiparas and 3 h for multiparas, the VAS score was greater than 3 but the anesthetic drug dosage did not reach the maximum allowed dosage at the same time. The average anesthetic drug dosage was positively correlated with fever, urinary retention, uterine atony, prolonged active phase, prolonged second stage, assisted vaginal delivery, and postpartum hemorrhage. The average anesthetic drug dosage was the highest in women ≤ 20 years old, those with a body mass index (BMI) ≥ 24.9 kg/m2, and those with a primary or secondary education level. Conclusion Appropriate age guidance and emphasis on education of labor analgesia, weight management during pregnancy, and real-time anesthetic dosage adjustment during labor based on VAS pain score may have positive effects on the satisfaction of labor analgesia.
