“…16 Spinal anesthesia also causes redistribution of heat from the core to the periphery, and whether this redistributed heat (from the core to the periphery) can increase skin temperature is still unclear. 17 Therefore, in this study, in addition to ΔTc, ΔTs were monitored.…”

BACKGROUND: Intraoperative hypothermia is a common complication after neuraxial block in cesarean delivery. At least 1 animal study has found that carbohydrate loading can maintain the body temperature of rats during general anesthesia, but it is unclear whether carbohydrate loading is beneficial for body temperature maintenance in parturient women during combined spinal-epidural anesthesia (CSEA) for elective cesarean delivery. METHODS: Women undergoing elective cesarean delivery were randomized into a control group (group C), an oral carbohydrate group (group OC), or an oral placebo group (group OP), with 40 women in each group. Core body temperature (Tc) and body surface temperature (Ts) before and after cesarean delivery, changes in Tc (ΔTc) and Ts (ΔTs), and the incidence of side effects (eg, intraoperative shivering) were compared among the groups. RESULTS: The postoperative Tc (core body temperature after cesarean delivery [Tc2]) of group OC (36.48 [0.48]°C) was higher than those of group C (35.95 [0.55]°C; P < .001), and group OP (36.03 [0.49]°C; P = .001). The ΔTc (0.30 [0.39]°C) in group OC was significantly smaller than those in group C (0.73 [0.40]°C; P = .001) and group OP (0.63 [0.46]°C; P = .0048). CONCLUSIONS: Oral carbohydrate loading 2 hours before surgery facilitated body temperature maintenance during CSEA for elective cesarean delivery.

“…Therefore, preoperative toe PI in parturients undergoing cesarean delivery under spinal anesthesia may be suitable for identifying those at high risk of intraoperative core temperature decrease. On the other hand, a previous secondary analysis in a randomized controlled trial showed that preoperative anterior thigh temperature does not correlate with the maximum perioperative temporal temperature decrease during cesarean delivery under spinal anesthesia [ 8 ]. This may have been influenced by the choice of anterior thigh temperature as peripheral temperature measurement site, where the magnitude of body temperature redistribution is small.…”

“…The early identification of parturients at high risk of intraoperative core temperature decrease is desirable to prevent maternal hypothermia in the perioperative period of cesarean delivery under spinal anesthesia [ 8 , 32 ]. Herein, our study results suggest that low preoperative toe PI may be an effective tool for the early prediction of maternal core temperature decrease during cesarean delivery.…”

“…However, the benefits of single active warming on maternal temperature are limited, with most studies reporting no more than 0.2–0.5 °C core temperature difference between active warming and control groups [ 2 ]. Recently, several clinical studies have been conducted to preoperatively identify parturients at high risk of perioperative body temperature decrease and hypothermia during cesarean delivery; however, the results remain unclear [ 8 ].…”

Association between preoperative toe perfusion index and maternal core temperature decrease during cesarean delivery under spinal anesthesia: a prospective cohort study

et al. 2021

Background The main mechanism of body temperature decrease during cesarean delivery under spinal anesthesia is core-to-peripheral redistribution of body heat, attributable to vasodilation. Perfusion index (PI) obtained with a pulse oximeter helps to assess peripheral perfusion dynamics by detecting the change in peripheral vascular tone. This study aimed to examine whether preoperative toe PI could predict the decrease in core temperature induced by spinal anesthesia during cesarean delivery. Methods Parturients undergoing scheduled cesarean delivery under combined spinal-epidural anesthesia from September 2019 to March 2020 were enrolled in this single-center prospective cohort study. All parturients received 0.5% hyperbaric bupivacaine (10 mg) with fentanyl (15 μg) intrathecally. A pulse oximeter probe was placed on the left second toe for continuous PI measurement. The 3 M™ Bair Hugger™ Temperature Monitoring System placed over the right temporal region was used to record core temperature over time. We evaluated the association between the maximum core temperature decrease, which is the primary outcome, and the preoperative toe PI at operating room (OR) admission using a segmented regression model (SRM) and a generalized additive model (GAM). The maximum core temperature decrease was defined as the difference between core temperature at OR admission and minimum intraoperative core temperature. Results Forty-eight patients were evaluated. In the SRM, the slope for the association between the maximum core temperature decrease and the preoperative toe PI changed from 0.031 to 0.124 after PI = 2.4%. Likewise, with the GAM, there was a small core temperature decrease when preoperative toe PI was greater than 2.0 to 3.0%. Conclusions Low preoperative toe PI was associated with maternal core temperature decrease during cesarean delivery under spinal anesthesia. Preoperative toe PI is a simple, non-invasive, and effective tool for the early prediction of perioperative core temperature decrease during cesarean delivery.
