To prospectively study postoperative early infection of orthopaedic sterile incision so as to identify risk factors.

To investigate and follow up the incidence of early postoperative infection in patients with type I incision admitted to the Orthopedic Center of our hospital from January 1 to June 30, 2020. The 27 indicators that may affect postoperative incision infection were age, gender, occupation, urban or rural area, BMI, smoking history, allergic history, operation history, preoperative complications, and cause of injury The time from injury to operation, anesthesia time, anesthesia method, invasive operation (radial artery manometry), operation duration, intraoperative blood loss, intraoperative blood transfusion, intraoperative lens input, intraoperative colloid input, intraoperative body temperature, preoperative antibiotics, ASA classification; preoperative laboratory examination: routine blood test, liver and kidney function, hemagglutination analysis, univariate screening and logistic regression were performed Objective to analyze and screen the independent risk factors of early postoperative incision infection.

A total of 759 patients were followed up, the follow-up rate was 97.4%. There were 420 males and 339 females with an average age of (41±22) years. During the follow-up period, 24 patients had surgical incision infection, the infection rate was 3.16%, and Staphylococcus aureus infection was the main infection (55.6%). In univariate analysis, there were significant differences in anesthesia mode, white blood cell (WBC), neutrophil count (neut) and serum albumin (ALB) between the two groups (P<0.05). Logistic regression model analysis indicated that preoperative ALB (P<0.05) were independent risk factors for early postoperative infection of incisional Wound, The probability of infection in orthopedic sterile early incision. ALB≤35 g/L, the infection rate as high as 23.43%.

Highlighting preoperative ALB levels in patients has an important role in improving the prevention of early infection in orthopedic sterile incision.
