title: How to prevent the infection of contaminated abdominal incisions.
abstract: BACKGROUND
  Surgical site infection is one of the most common complications of conventional laparoscopic surgery. Preventing infection of the incision is particularly important.
  
  
  OBJECTIVE
  To discuss how to prevent the occurrence of surgical site infection after contaminated abdominal surgery.
  
  
  METHODS
  Five hundred and fifty-one surgery patients with ``contaminated abdominal incisions'' from January 2011 to May 2013 were analyzed in terms of the preventative treatment, and summarized for surgical site infection. Subcutaneous tissue flushed with normal saline + hydrogen peroxide before suturing in the intervention 1 group; subcutaneous tissue flushed with normal saline + 0.5% povidone-iodine before suturing in the intervention 2 group.
  
  
  RESULTS
  When subcutaneous fat was contaminated to a depth of ≤ 2.5 cm, the rates of surgical site infection in the control group and the intervention groups showed no significant difference (P > 0.05). When subcutaneous fat was contaminated to a depth of ≥ 3.0 cm, the rate of surgical site infection in the control group compared with the intervention one group was not statistically different (P > 0.05). The rate of surgical site infection in the control group compared with the intervention two group was statistical significant (P < 0.05). The rate of surgical site infection in the intervention one group compared with the intervention two group was statistical significant (P < 0.05).
  
  
  CONCLUSIONS
  Preoperative control of the blood sugar; correction of anemia and the hypoalbuminemia; use of intraoperative the high-frequency electrotome; irrigation of the incision with plenty of physiological saline +$ iodophor before suturing the subcutaneous fat layer were key to effectively preventing infection in contaminated abdominal incisions.
