Vacuum sealing drainage combined with iodophor douche for the prosthesis infection after artificial joint replacement / 中国组织工程研究

ABSTRACT

BACKGROUND:Periprosthetic infection after artificial joint replacement is a disastrous complication for a patient. Currently, during treating for the periprosthetic infection, most of patients need two-stage revision, which bring about enormous physical and psychological pain for patients, and a heavy burden for the families and society. To make matters worse, the effect is not very perfect, and some of these cases require multi-stage revision, even amputation. OBJECTIVE:To investigate the therapeutic effect of vacuum sealing drainage combined with iodophor douche for the infection after artificial joint replacement. METHODS:Nine cases (six knees and three hips) of infection after artificial joint replacement were col ected, with an average age of 63.4 years. Infection occurred at 7 days-14 months, and a median time of 1 month after replacement. Al patients suffered from purulent or purulent blood secretion. Fistula formed in two cases and incision and drainage sites were not healed in one case. According to the bacterial culture results, above symptoms were accorded with clinical diagnosis of prosthesis infection. The prosthesis was remained for debridement. Vacuum sealing drainage was performed. Iodophor douche (30-50 mL) was conducted every day. The drainage tube at proximal end was occluded for 30 minutes, and then vacuum sealing drainage was performed. Al patients were regularly fol owed up to assess the therapeutic effects of vacuum sealing drainage combined with prosthesis infection after replacement. RESULTS AND CONCLUSION:(1) Except that one case was stil in treatment, one case was dead, and one case of tumor prosthesis was failure and final y amputated, the remaining six patients were healed. (2) The time of vacuum sealing drainage and iodophor douche was 10 to 84 days, with the median time of 57 days. No adverse reactions or complications occurred. Al healed patients were fol owed up for 12-60 months, without recurrence. (3) These results indicated that vacuum sealing drainage combined with iodophor douche retained the prosthesis to the greatest degree, is simple, safe, and effective for the infection after artificial joint replacement, needs a low cost, and is a kind of therapy for prosthesis infection after artificial joint replacement.
