| Summary: | Background:. Pressure injuries (PIs) are common in hospitalized patients, with incidence exceeding 50% in high-risk patients. Immobilization causes a prolonged compression of vascular networks in tissues overlying bony prominences, leading to ischemia and ulceration. Traditionally, PIs are treated with a combination of surgical debridement and reconstruction. This approach can be invasive for debilitated patients who cannot tolerate prolonged surgeries and extensive tissue resection. Hydrosurgery uses high-pressure irrigation to low-invasively debride and cleanse wounds; its use has shown positive outcomes in burn and chronic wounds care. Here, we hypothesize that hydrosurgery allows low-invasive yet effective wound bed preparation in truncal PIs.
Methods:. We conducted a single-center, prospective, uncontrolled case series. Inclusion criteria for this study were presence of a truncal PI (stage III or IV) and an American Society of Anesthesiologists physical status of ≥2 (no exclusion criteria). Measured outcomes included duration of hydrosurgery, postsurgical local (dehiscence, infection, seroma) or systemic complications in the first 30 days, and PI recurrence rate (6-month follow-up).
Results:. Seven patients (3 sacral, 2 greater trochanteric, and 2 ischial tuberosity PIs) were enrolled for this study. Average duration of hydrosurgery was 12 minutes (±3.1). No local or systemic complications were observed at a 30-day follow-up (0/7, 0%). All flaps (6/7, 86%) and graft (1/7, 14%) reconstructions successfully survived, and no PI recurrence was reported within a 6-month follow-up (0/7, 0%).
Conclusions:. Hydrosurgery seems to allow safe, low-invasive, and effective wound bed preparation in truncal PIs. Larger controlled trials are needed to confirm this preliminary evidence, to guide its broader adoption for improved care of high-risk patients with PIs.
