Abstract:
Background and Aims:Elderly patients with inguinal hernia are prone to intraoperative hypothermia due to diminished thermoregulatory capacity,which may increase the risk of postoperative complications such as infection,seroma,and cognitive dysfunction.This study aimed to investigate the relationship between intraoperative body temperature and postoperative complications in elderly patients undergoing inguinal hernia repair and to evaluate its predictive value.Methods:Clinical data of 358 elderly patients who underwent tension-free inguinal hernia repair at the Affiliated Hospital of Southwest Medical University from April 2018 to October 2024 were retrospectively analyzed.Patients were divided into a hypothermia group(<36.0℃)and a normothermia group(≥36.0℃)according to intraoperative temperature levels.Perioperative parameters and postoperative complications were compared between the two groups.Independent risk factors for complications were identified using multivariate logistic regression,and the predictive performance of intraoperative temperature was evaluated by receiver operating characteristic(ROC)curve analysis.Results:Compared with the normothermia group,patients with intraoperative hypothermia had significantly longer operative time,higher postoperative white blood cell(WBC)count and neutrophil-to-lymphocyte ratio(NLR),and an increased incidence of complications(25.0%vs.3.8%,P<0.001).Multivariate analysis identified age,NRS 2002 score,intraoperative blood loss,postoperative WBC,postoperative NLR,and intraoperative hypothermia as independent risk factors for postoperative complications.ROC analysis showed that intraoperative temperature had a good predictive value for complications(AUC=0.717,optimal cutoff=36.42℃,sensitivity=70.0%,specificity=89.5%).Conclusion:Intraoperative hypothermia significantly increases postoperative complication risk in elderly patients undergoing inguinal hernia repair.Maintaining intraoperative temperature above 36.4℃may reduce the incidence of complications and improve perioperative outcomes.
