Abstract: Objective: To investigate the characteristics of intraoperative Pressure Injury among children undergoing liver transplantation and to analyze its influencing factors, so as to provide basis for preventing intraoperative Pressure Injury in liver transplantation. Methods: The relevant data of children undergoing liver transplantation were collected in one children's hospital in Chongqing from 2007 to 2018. Demographic data, intraoperative Pressure Injury information and possible influencing factors were collected and analyzed. Results: A total of 101 children undergoing liver transplantation were recruited, and 20 children developed intraoperative Pressure Injury with an incidence of 19.8%. Intraoperative Pressure Injury was mostly occurred in the head and face (67.8%), and the stage of pressure ulcer was mainly stage 1 (85.7%). Logistic regression analysis indicated that Braden Q score, albumin, hypothermia in non-hepatic stage were the influencing factors of Pressure Injury among children undergoing liver transplantation. Conclusion: Children undergoing liver transplantation were at high risk of intraoperative Pressure Injury. We should pay attention to the Braden Q score and albumin before surgery, and supervise the vital signs of children to find out whether hypotension or hypothermia occurred in an hepatic phase or reperfusion phase,so as to effectively prevent intraoperative Pressure Injury and enhance the quality of nursing.
