Abstract
The treatment of pressure ulcer is of an extreme clinical and social concern. Effective and thorough debridement lays the foundation for favorable wound healing. Recently, a case report confirmed the efficacy of a combined application of methylene blue staining and ultrasonic debridement for pressure ulcer debridement. A 91-year-old male who suffered from severe pressure ulcers for over 6 years eventually obtained a favorable restoration after receiving surgical debridement optimized with methylene blue staining and ultrasonic debridement. We write to learn more about the details of the case. In this letter, we raised some questions involving the identification capability of methylene blue staining among different tissues, the application of methylene blue staining for various wounds, the arrangement of the debridement liquid, and the management strategy after wound closure. We thank the authors for creating a successful paradigm and hope the discussion can make sense for guiding subsequent clinical practice.
