Pediatric Abdominal Incision ? Class Postoperative Incision Infection Analysis Of Influencing Factors

Objective To analysis the risk factors for abdominal surgical site infection(SSI)of type?,so that providing a reference for the prevention of postoperative infection of class ?abdominal incision in children.Method Collecting the clinical data of all children aged 0-15 years who were treated in pediatric surgery department of general hospital of Ningxia medical university from January2014 to January 2017.The patients were divided into infection group(41 cases)and non-infection group(350 cases).Comparing the influence factor between the two groups: age,nationality,gender,onset season,nutritional status,hospitalization time,timing of operation,WBC before operation,albumin before operation,NEUT% before operation,hemoglobin before operation,disease type,operation time,incision type,incision length,whether to use incision protector,ascites characteristics,ascites volume,whether to wash the abdominal cavity,whether to place drainage tube,whether to perform intestinal resection intestinal anastomosis,blood transfusion.Spss 20.0 was used for statistical analysis.Results There were 41 children suffering from SSI,the infection rate of which was 10.49 %.The average postoperative infection time was 6.829?0.393 days.The factors affecting SSI were emergency operation,nutritional status,operation time > 1.5 h,low preoperative albumin,long incision length,large amount of ascites,no irrigation of abdominal cavity,no drainage tube and no blood transfusion(P< 0.05).By multivariate logistic regression analysis,5 independent factors affecting incision infection after class ?abdominal incision in children were obtained.The influence degree as follows: obesity(OR=1.970),emergency operation(OR=1.879),operation time >1.5h(OR=1.394),washingthe abdominal cavity(OR=0.775),preoperative blood transfusion(OR=0.482).Necessary intervention should be given in clinical practice.Conclusion Emergency operation,nutritional status,operation time >1.5h,low preoperative albumin,long operative incision length,large amount of peritoneal effusion,no irrigation of abdominal cavity,no drainage tube,blood transfusion are related to the occurrence of incision infection after type ? abdominal incision in children.The independent risk factors of incision infection after type ? abdominal incision in children were obesity,emergency operation,operation time >1.5h.And the protective factors of incision infection after type ? abdominal incision in children were washing abdominal cavity and preoperative blood transfusion.
