Risk factors and prediction model for pressure injury in children undergoing extracorporeal circulation surgery
Objective To investigate the current situation of pressure injury in children undergoing extracorporeal circulation surgery and construct a prediction model to better understand and predict the risk of pressure injury.Methods The data of children with pressure injury during extracorporeal circulation surgery treated in Hunan Children's Hospital from July 2021 to December 2023 were retrospectively analyzed,and the current situation was investigated and a prediction model was established.Results A total of 283 subjects were included in this study,59 of which had pressure injury,with an incidence of 20.8％.Gender,preoperative Braden score,anesthesia grade and intraoperative blood loss were the factors influencing the occurrence of pressure injury in children undergoing extracorporeal circulation(P＜0.05).Prediction model:Logit(P)=-1.383+1.403 × gender+1.149 × anesthesia grade-1.537 × preoperative Braden score+0.770 × intraoperative blood loss;the sensitivity was 0.749 and specificity was 0.832.Conclusion The incidence of pressure injury in children undergoing extracorporeal circulation surgery is relatively high,and it is affected by four factors:gender,preoperative Braden score,anesthesia grade and intraoperative blood loss.The risk prediction model based on the above four risk factors has a good effect,which can be used for clinical screening of children at high risk of pressure injury during extracorporeal circulation surgery.
