Abstract To investigate the influencing factors of the risk of postoperative surgically derived hypothermia of parturients after cesarean, and to construct the nomogram prediction model. Methods: The clinical data of 196 parturients with postoperative surgically derived hypothermia after cesarean (in study group) from February 2020 to September 2021 were analyzed retrospectively. 196 parturients without postoperative surgically derived hypothermia after cesarean were selected in control group. The difference of the data of the parturients was compared between the two groups. The independent risk factors affecting the risk of the postoperative surgically derived hypothermia parturients after the cesarean were screened by univariate and multivariate analysis, and then the Nomograms model were drawn and were validated. Results: The results of multivariate Logistic regression analysis showed that the hypothyroidism, the spinal anesthesia, the temperature after anesthesia <36.75 ℃, the volume of peritoneal fluid flushed during surgery >800 ml, the volume of body fluid lost during surgery >980 ml, no active insulation measure, no warm fluids of transfusion, and the room temperature ≤23℃ were all the independent risk factors of hypothermia of the parturients after cesarean (P<0.05). Conclusion: 8 independent risk factors of hypothermia of the parturients after cesarean were identified in this study, and the Nomograms drawn based on these factors has good accuracy for predicting the surgically derived hypothermia of the parturients after cesarean, and which has clinical value for preventing the maternal hypothermia.
