Application of jie you shen long-acting antimicrobial material in prevention of pin tract infection in percutaneously pinned pediatric distal humeral fractures

Abstract

Objective To evaluate the curative effect of jie you shen (JUC) long-acting antimicrobila material (JUC) in preventing pin tract infection in pediatric distal humeral fractures treated with closed reduction and percutaneous Kirschner pin fixation. Methods A total of 160 pediatric patients were given distal humerus fracture surgery by fixation with percutaneous Kirschner pins. After Kischner pin fixation, the pintails and the affected limbs were sprayed with placebo/JUC first, and then wrapped with gauze immersed with placebo/JUC, followed by immobilization with plaster cast at flexion of the elbow. Pin tract infections were evaluated at the time of plaster removal 4-6 weeks after surgery. Results Postoperative Kirschner pin tract infection rate was 1.25% in JUC group, and Staphylococcus aureus was isolated from one patient. The postoperative Kirschner pin tract infection rate was 10.00% in placebo group, including 7 patients infected with Staphylococcus aureus and one patient with Pseudomonas aeruginosa. The infection rate in the JUC group was significantly lower than that in the control group (P=0.016). Conclusion JUC long-acting antimicrobila material can efficiently decrease postoperative pin tract infection after percutaneous Kirschner pin fixation surgeries in pediatric distal humerus fracture patients receiving closed reduction.
