Abstract: Objective  To explore the  highrisk factors of pressure injury(PI) in severely ill children. Methods  151 children were divided into PI group and non PI group  according to the presence or absence of PI. The occurrence of PI in severely ill children was analyzed, and  the  risk factors of PI in severely ill children  were analyzed. Results  A total of  25 cases occurred in  151 children, and the incidence rate  of PI was 16.57%. PI staging included: 20 cases  in stage  Ⅰ, 4 cases  in stage Ⅱ, and 1 case  in stage Ⅲ. There were 29 PI sites in 25 patients  and 18 in the head and face(62.07%). Respiratory mode, PICS score, medical device use and Braden Q score were the independent risk factors of  the occurrence of PI in severely ill children(P<0.05). Conclusion  Children with  severe  diseases are at high  risk of PI, and most of the injuries  are in the head and face,mainly in phase I. PCIS score, respiratory mode, medical device use and Braden Q score are highrisk factors of PI in severely ill children.
