The Efficacy Of Modified Continuous Negative Pressure Drainage Device In Treating The Infection Of Orthopedic Fixation Postoperative In 42 Cases

Objective: To evaluate the clinical efficacy of modified continuous negative pressure drainage device in treating wound infection after orthopedic fixation.Methods: Our hospital in January 2013- March 2015 period, forty-two cases suffering from infection after orthopedic fixation, which included 35 cases of superficial infection and deep infection of 7 cases. All patients with the fixations reserved, were treated by the method of continuous negative pressure drainage. Continuous negative pressure drainage with intravenous antibiotic therapy plus treatment of primary disease, nutrition therapy, wound debridement and retention of implants is effective method for management of the infections after orthopedic fixation.Results: All of the 42 cases were treated by the ways of continuous negative pressure drainage device to cure the postoperative infections. Each patient should be treated by this method is roughly 1 to 3 times(means 1.31 times) and draining was applied for 12 to 18 days(means 13.62days) each time. Each patient was followed up 3 to 24 months(means 12.00 months) after operation. The result of continuous negative pressure drainage treatment was encouraging. Incision of 41 cases were healed well, no infection, no pain and no redness seepage conditions happening. But the result was not invariably satisfied of using the treatment in one patient. Although the various methods of treatment applied, the wound of the patient was constantly seeping. Not satisfied with the treatment results may be associated with the peroneal nerve injury.Conclusion: Our experiences indicate that implants retention and improvement of continuous negative pressure drainage for postoperative infection can provide satisfactory results. Results the use of continuous negative pressure drainage were satisfactory. It is a reliable treatment for treating postoperative infection, which can effectively remove the necrotic and exudates and control the infection of orthopedic fixation.
