Abstract:

Objective To explore trend of the core temperature variation，the incidence of perioperative hypothermia and influencing factors during pediatric living-donor liver transplantation，so as to provide a theoretical basis for policies and procedures for prevention and treatment of hypothermia. Methods Cluster sampling method was used to collect the clinical data of 334 pediatric patients who underwent living-donor liver transplantation from November 2017 to December 2023 at a tertiary general hospital in Shanghai. Based on literature review method and expert meeting method，a questionnaire on influencing factors for intraoperative hypothermia during pediatric living-donor liver transplantation was designed and was used for investigation. Univariate analysis and logistic regression analysis were applied to identify the influencing factors. Results During the pediatric living-donor liver transplantation，the core temperature shows the variation trend of “slowly increase-rapidly decrease-recover-stabilization”. The incidence of intraoperative hypothermia is 55.09%. Logistic regression analysis revealed that gender，age in months，body weight，Child-Pugh score，baseline temperature upon admission，duration of surgery，and duration of anesthesia are factors influencing the occurrence of hypothermia during living donor liver transplantation in infants and young children. Conclusion The incidence of hypothermia in pediatric living-donor liver transplantation is high. Perioperative nurses should attach importance to evaluate the influencing factors for hypothermia and develop strategies to minimize the risk of hypothermia in pediatric patients who underwent living-donor liver transplantation at risk.
