Wound healing in stage IV pressure injury with use of adjunct autologous activated platelet-rich plasma therapy: a case report.

Introduction: Pressure injuries remain a major burden worldwide with associated morbidity and financial implications. Patients in the ICU, such as those with severe COVID-19, are especially susceptible to PI as they remain immobile for extended durations while intubated.

Objective: This report examines a case of stage 4 PI in a senior COVID-19 survivor treated with adjunct intravenous and intralesional aaPRP therapy in addition to topical hyaluronic acid/silver sulfadiazine cream and framycetin sulphate dressing.

Case Report: aaPRP therapy was administered via intralesional injection and intravenous infusion 4 times with 2 weeks between therapies, while the aforementioned topical cream and dressing were applied every 2 days between visits. The patient also had controlled diabetes which may affect the wound healing process.

Conclusions: This report concludes with a discussion of how COVID-19 carries important dynamics in the pathogenesis of PI and how adjunct administration of intravenous and intralesional aaPRP, which is abundant in regenerative proteins, may be beneficial in the management of PI.
