Abstract:
Objective:To access the efficacy of external fixation combined with Prontosan management for open fractures complicated with multidrug-resistant bacterial infection.Methods:A retrospective analysis was conducted of the data of 22 patients with open fracture complicated by multidrug-resistant bacterial infection who had been admitted to Department of Orthopedic Trauma and Microsurgery, Zhongnan Hospital of Wuhan University from January 2015 to January 2020. According to whether the Prontosan management was used or not, the patients were divided into 2 groups.The Protosan group [9 males and 3 females with an age of (44.6±13.1) years] were subjected to external fixation, vacuum sealing drainage(VSD) or conventional dressing changes, and at the same time Protosan management to flush the wound or Prontosan gel to change dressings.The control group[6 males and 4 females with an age of (45.1±11.7) years] were subjected to external fixation plus VSD or conventional dressing changes. Skin flaps or skin grafts were used to repair the wound immediately after the wound infection was controlled in both groups. The time for negative culture of the bacteria on the wound surface, number of debridement, survival of the skinflaps or grafts, and fracture union were recorded and compared between the 2 groups.Results:There was no significant difference in the preoperative general data between the 2 groups which were comparable( P>0.05).All patients were followed up for 10 to 24 months (mean, 14.5 months).In the Prontosan group, the number of debridement was 2.0 (2.0, 3.0) times, significantly fewer than that in the control group [4.0 (3.0, 4.0) times]; the time for negative bacterial culture (8.3±2.2) d, significantly shorter than that in the control group [(14.2±3.1) d]; the fracture union time (5.5±1.1) months, significantly shorter than that in the control group [(6.5 ±1.1) months]; the Samantha X-ray score at 6 months after operation 6.0 (5.0,6.0) points, significantly higher than that in the control group [5.2(4.5,5.5) points] (all P<0.05). Skin flaps or grafts survived in all the patients without any nonunion or chronic osteomyelitis. Conclusion:In the external fixation of open fractures complicated with multidrug-resistant bacterial infection, combination with Prontosan management can effectively control infection and promote granulation, early wound healing and fracture union.
