Abstract：Objective To analyze the influencing factors of contralateral auricular intraoperative acquired pressure injury in pa-tients undergoing external ear reconstruction for congenital microtia,and to provide basis for the prevention of intraoperative acquired pres-sure injury.Methods From January 2022 to December 2023,a matched case-control study was conducted.All 1905 cases,the matching rule is 1:2.The 25 patients with contralateral auricle intraoperative acquired pressure injury after ear reconstruction surgery were as the case group and 50 patients without intraoperative acquired pressure injury as the control group.Then patients'medical records were re-viewed to identify risk factors of contralateral auricle intraoperative acquired pressure injury.Results Totally 1905 patients were selected.There were 25(1.3％)patients had intraoperative acquired pressure injury,among which 22 had stage 1 pressure injury,3 had stage 2 pres-sure injury.There were significant differences between hypothermia,surgery time,total albumin,albumin,prealbumin,bleeding volume in univariate analysis(P＜0.05).In multi-factor analysis,hypothermia,surgery time ≥ 3 hours,bleeding volume ≥ 50 milliliters and prealbu-min decreased had a significant effect(P＜0.05).Conclusion There are more risk factors for intraoperative acquired pressure injury of contralateral auricle in patients undergoing external ear reconstruction.Patients with intraoperative hypothermia,long surgery time,large amount of blood loss and decreased prealbumin should be focused.The preventive strategies need to be applied for the high risk patients in order to reduce the incidence of pressure injury,ensure the safety of the patients and improve the quality of nursing in the operation room.
