Intraoperative hypothermia is a common complication during cesarean section (C-section) and associated with the high maternal mortality and morbidity. This study aimed to explore the risk factors associated with the incidence of intraoperative hypothermia in women who underwent emergency C-section deliveries.
We retrospectively enrolled women who underwent emergency cesarean deliveries from August 2022 to Dec 2023 at Suzhou Municipal Hospital of Anhui Province. Baseline characteristics, thermal status, and perioperative information were extracted. Hypothermia was defined as the onset of a core temperature below 36 °C. Data were compared between patients with and without a hypothermia during surgery. Logistic regression analyses were performed to determine the risk factors for low-temperature-status.
Overall, 87 patients were included, and 30 underwent hypothermia during surgery. For women with a normal temperature status, women in the hypothermia group had a lower incidence of receiving active warming methods (52.6% vs. 30%, P = 0.044). In the logistic regression model involving core temperature, a pre-surgery core temperature < 36.5 °C (OR 4.22, 95% CI 1.13-15.63, p = 0.032) and a long surgery duration (per 10 min, OR 1.97, 95% CI 1.24-3.11, p = 0.004) were associated with a high probability of hypothermia. Administering active warming methods to women can reduce the risk of experiencing a hypothermia during emergency C-sections (OR 0.19, 95% CI 0.05-0.63; p = 0.007).
Hypothermia is common in emergency C-section deliveries. It is recommended that active warming methods should be applied to parturient undergoing emergency C-sections more proactively, especially for women who have a low baseline core temperature (< 36.5 °C) and are expected to have a long surgery duration.
术中低体温是剖宫产（C 剖）中常见的并发症，与产妇高死亡率和发病率有关。本研究旨在探讨与接受紧急 C 剖分娩的女性术中低体温发生率相关的危险因素。
我们回顾性纳入了 2022 年 8 月至 2023 年 12 月在安徽省苏州市立医院接受紧急 C 剖的女性。提取基线特征、体温状况和围手术期信息。术中低体温定义为核心温度低于 36°C。比较术中发生低体温与未发生低体温的患者数据。使用 logistic 回归分析确定低温状态的危险因素。
共纳入 87 例患者，其中 30 例在手术中发生低体温。对于体温正常的女性，低体温组接受主动升温方法的比例较低（52.6% vs. 30%，P=0.044）。在涉及核心温度的 logistic 回归模型中，术前核心温度<36.5°C（OR 4.22，95%CI 1.13-15.63，p=0.032）和手术时间长（每 10 分钟，OR 1.97，95%CI 1.24-3.11，p=0.004）与低体温的高发生率相关。对女性使用主动升温方法可降低紧急 C 剖时发生低体温的风险（OR 0.19，95%CI 0.05-0.63；p=0.007）。
紧急 C 剖中低体温很常见。建议对接受紧急 C 剖的产妇更积极地使用主动升温方法，尤其是对于基线核心温度较低（<36.5°C）且预计手术时间较长的女性。
