Clinical evaluation of continuous irrigation with Bikerui combined with negative pressure closed drainage and platelet-rich plasma technique for treatment of stage III-IV pressure ulcer.

Introduction: As a catastrophic complication of bedridden and elderly patients, pressure ulcer usually continuously affects patients' health and quality of life, so the daily care of wounds is attached great importance in clinic.

Aim: This work investigated the effect of Bikerui disinfectant + vacuum sealing drainage (VSD) + platelet-rich plasma (PRP) therapy on patients with stage III ~ IV pressure sore.

Material and methods: In this work, 110 patients with pressure ulcer (PU) treated in our hospital were enrolled and were randomly divided into an experimental group (Exp group) and a control group (Ctrl group) by a blind selection method, with 55 cases in each group. Patients in the Ctrl group received surgical debridement + VSD for treatment, while those in the Exp group were treated with Bikerui disinfectant + VSD + PRP. Inflammatory response (IR) score, PU healing (PUH) score, healing time, dressing change frequency (DCF), dressing interval time (DIT), and scar recovery (SR) score of patients in different groups were compared.

Results: The results revealed that the positive rate of bacterial culture in wound secretions in the Exp group was greatly lower than that in the Ctrl group 1 or 2 weeks after treatment (p < 0.05). The IR score in the Exp group was much lower at week 1 and 2 after treatment (p < 0.05). The total effective rate (TER) in the Exp group was obviously higher than that in the Ctrl group (94.55% vs. 76.36%).

Conclusions: The results suggested that Bikerui disinfectant + VSD + PRP therapy could effectively improve the inflammatory degree of PU patients, promote the wound repair and scar recovery of patients, and greatly improve the clinical efficacy of PU patients.
