Abstract: Objective: To analyze the risk factors of occipital pressure, injury after living donor liver transplantation in in infants and young children. Methods: Prospectively observed and collected clinical data and postoperative occipital pressure injury in pediatric patients who received living donor liver transplantation in our hospital from October 2018 to December 2019, and analyzed the related risk factors of occipital pressure injury. Results: The incidence of occipital pressure injury was 6.4% (14/220). The independent risk factors for occipital pressure injury were the temperature difference between the occipital compression area pre-operation and the core of nasopharynx during operation >0.7℃, the temperature difference between the occipital compression area pre-operation and its peripheral extension 2 cm area during the operation >1.0℃, the skin temperature difference of the occipital compression area pre-operation and post-operation >1.0℃. Conclusion: It is recommended that the occipital and surrounding skin temperature of pediatric undergoing living donor liver transplantation should be monitored in real time. Protective intervention should be taken to prevent the occurrence of pressure injury for those susceptible pediatric.
