Jet Lavage Irrigation Resolves Stage 4 Pelvic Pressure Injury Undermining.
James B Stiehl
PMID 37471449WHAT IT FOUND
In five nursing home patients with severe stage 4 pressure injuries, low-pressure jet lavage irrigation resolved deep undermining in four cases.
The fifth showed improvement but died of COVID-19. No systemic infections occurred, though four patients died during the study.
Key findings
01Jet lavage irrigation resolved undermining and tunneling in four of the five cases, with the fifth showing improvement before death.
02No evidence of systemic sepsis or complications from the irrigation method was found in any patient.
03The procedure was performed at the bedside in a long-term care facility by physical therapists using a specialized femoral canal tip.

What it does not show
The study is a very small case series of only five patients. Four of the five patients died during the study period, making long-term healing outcomes uncertain. The patients were considered palliative and poor candidates for surgery, so results may not apply to healthier patients. There was no control group, so the effect of the irrigation cannot be separated from other concurrent care or natural history. The study was conducted by a single author and a small team, limiting generalizability.
Declared interests
The author is the sole researcher and clinician involved in the study design, data collection, and interpretation. No external funding or commercial conflicts of interest are explicitly declared in the text provided, but the author uses specific devices (MolecuLight, SnapshotNIR) and techniques they advocate for.
The easy way to misread this
Do not assume this technique is safe or effective for all stage 4 pressure injuries. The high mortality rate in the study group (four of five died) reflects the severe underlying health of these palliative patients, not the treatment's failure. Without a control group, it is impossible to know if the wounds would have healed or improved with standard care alone.
