Clinical Analysis fo the Postoperative Infection in Traumatic Patients / 대한정형외과학회잡지

ABSTRACT

Clinical analysis of ths pcstoperative infection has been made on 511 traumatic patients, who had been admitted and operated in Orthopedic Department of Kyungpook National University Hospital during the period from January, 1972 to June, 1975. The following results were obtained. 1. Of the total 511 traumatic patients operated, 39 cases were infected, the infection rate being 7.6%. 2. The infection rate was higher (21.2%) in case of mutiple trauma than single trauma(3.6%) and also higher rate of infection was seen in the open wound(8.7%) than closed one(4.1%). 3. The most frequently involved sites of the trauma were the tibia and the femur occupying 51.9% of the total, and the next were the forearm and hand in decreasing order, but the highest infection rate was seen in the cases with hand injury(11.6%). 4. The incidence of infection was 15.7% in the debrided wound of crushing injury 14.0% in the cases with open fracture, and 4.1% in the closed fracture. 5. In relation to the operating time consumed, the infection rate was 5.0% in the cases of less. than 2 hours but it rose up to 9.4% when operation time exceeded 4hours, suggesting that the longer is the operating time the higher is the infection rate. 6. The infection rate was relatively low in the open wounds operated within 6 hours after injury and also it is low when operation was done within 1 week in case of closed wound. 7. Of the isolated microorganisms, tho coagulase positive staphylococcus was the most frequent offender occupying 33.3% of the total, and was relatively sensitive to kanamycin, vibramycin, and albamycin. The next frequent organism was pseudomonas and was relatively sensitive to gentamicin.
