This randomized controlled trial evaluated pig’s toenail egg yolk ointment for Stage III–IV pressure ulcers in 80 patients, comparing it with conventional dressings. The ointment group had significantly lower Pressure Ulcer Scale for Healing scores, higher wound healing rates, and lower dressing costs than the control group (P < 0.05). Complementary rat experiments found faster healing, greater neovascularization, less inflammatory cell infiltration, increased VEGF, and reduced TNF-α and IL-1β; pathway findings were consistent with PI3K-Akt activation. The abstract does not report the magnitude of the clinical differences.
Key findings
- Among 80 patients, the ointment group had lower PUSH scores and higher wound healing rates than the conventional-dressing group (P < 0.05).
- Dressing costs were significantly lower with the ointment than with conventional dressings (P < 0.05).
- In rats, ointment treatment was associated with faster healing, increased neovascularization and VEGF, and reduced inflammatory markers.
Why it matters
Pressure ulcers can require prolonged wound care, and the reported clinical improvements alongside lower dressing costs suggest this ointment may warrant further evaluation. The animal findings offer a possible biological explanation involving angiogenesis and inflammatory modulation, but they do not establish that PI3K-Akt activation mediates the clinical effects in patients.
What to keep in mind
The abstract provides no numerical effect sizes for the clinical outcomes, and the mechanistic findings come from rat experiments rather than the patient trial.
