Abstract: Objective To explore the preventive effect of thermal insulation nursing on intraoperative hypothermia and postoperative shivering of cesarean section. Methods A total of 310 cases of cesarean delivery women from June 2019 to July 2020 were selected as study subjects. According to random number table, they were divided into a control group （155 cases）, who received traditional nursing measures, and an observation group （155 cases）, who received thermal insulation nursing in operation rooms. The body temperature of the two groups of pregnant women was compared at the time of entering operating room, 10 min of operation, and after operation. Intraoperative hypothermia and postoperative shivering cases were recorded, and the severity of shivering was evaluated. On the day after operation, the satisfaction of nursing among the pregnant women was investigated by questionnaire. Results The observation group showed higher body temperature than the control group at 10 min of operation [（36.62±0.39） ℃ vs. （35.91±0.43） ℃], and after operation [（36.27±0.38） ℃ vs. （35.63±0.42） ℃], with significant differences （P<0.05）. The incidence rates of intraoperative hypothermia （1.29% vs. 9.68%） and postoperative shivering （3.23% vs. 46.45%） in the observation group were lower than those in the control group, and shivering of the observation group was less severe than that of the control group, with significant difference （P<0.05）. The pregnant women in the observation group showed higher satisfaction of nursing than the control group （93.55% vs. 70.32%）, and the difference was statistically significant （P<0.05）. Conclusion The application of thermal insulation nursing during cesarean section can reduce the incidence of intraoperative hypothermia and postoperative shivering and improve satisfaction of nursing among pregnant women.
