Rationale: Pressure sores are major clinical problems with limited treatment options.
Patient concern: A 62-year-old man, admitted with unresponsive, indifferent mood, and malnutrition. A noval-shaped skin lesion deeping into the fascia was found in the sacrococcygeal region.
Diagnosis: The patient was diagnosed with delayed carbon monoxide poisoning encephalopathy and stage IV sacrococcygeal pressure sores.
Intervention: The patient received neurologic rehabilitation therapy and simple debridement dressing care followed by extracorporeal shockwave therapy.
Outcomes: The scores for the pressure ulcer healing scale were 17 points, 13 points, 9 points, and 5 points, respectively, before treatment and at the 4-, 8-, and 12-week follow-ups. At 2 weeks after discharging the total pressure ulcer healing scale score was 0, which signifies that the sacroiliac decubital necrosis healed without adverse reactions and side effects.
Lessons: This study presents a therapeutic solution for treating older adults with pressure ulcers by using extracorporeal shockwave with alginate dressing, which proved effective and safe.
