ObjectiveTo explore the clinical efficacy of platelet-rich technology combined with moist dressings in the treatment of chronic infectious ulcers.MethodsThis was a retrospective study. The subjects of the study were 48 patients with chronic infectious ulcers in Sichuan Provincial Orthopedics Hospital from January 2019 to June 2022. Enrolled patients were randomly divided into four groups(n=12), and received different treatment methods respectively. Further analysis and comparison were performed on the changes in wound volume, wound healing status, wound bacterial culture results, and the incidence of adverse reactions among the four groups.ResultsThree months after debridement, the wound volume of all four groups of patients was significantly reduced compared with that before debridement, with a statistically significant difference in intra-Group-Comparison(P<0.05). The inter-Group-Comparison revealed a statistically significant difference in wound volume in Group-A, Group-B, and Group-C than that in Group-D(P<0.05). After treatment, the wound healing status of patients in groups A, B, and C was significantly better than that of patients in Group-D, with a statistically significant difference(P<0.05). During treatment, patients in all four groups had decreased count of would bacteria, and showed negative results of wound bacterial culture by the three-month follow-up. No serious adverse reactions were observed in the four groups during treatment, and all improved after management, with no statistically significant difference in the incidence of adverse reactions(P>0.05).ConclusionPlatelet-rich technology combined with moist dressings may effectively promote the repair of chronic infectious ulcer wounds, with good clinical safety.Copyright: © Pakistan Journal of Medical Sciences.
