Clinical research on subcutaneous drainage tube in the prevention of abdominal surgical incision infection

Objective To observe the clinical effect of subcutaneous drainage tube in the prevention of abdominal surgical incision infection.Methods According the admission sequence,290 abdominal surgery patients were selected and randomly divided into the two groups,each group 145 cases.The patients of the observation gronp were placed subcutaneous drainage tube after operation,and the patients of the control group were not placed subcutaneous drainage tube.The wound healing,wound infection rate,and secondary debridement incidence of the two groups were observed and compared.Results The successful surgery were in 190 patients,and there was no patient in death.The incision healing rate of first grade in the observation group was 97.93％,which in the control group was 89.66％,The incision infection was in 3 cases (2.07％),which in the control group was 12 cases (8.28％).There were all statistically significant differences between the two group (all P ＜ 0.05).The secondary debridement of the observation group was in one case,which in the control group was in 7 cases,and the secondary debridement incidence of the observation group was significantly lower than that of the control group(P ＜ 0.05).Conclusion Placing the subcutaneous drainage tube for abdominal surgery patients can reduce the occurrence of wound infection and secondary debridement,and beconducive to postoperative recovery.
