Overview

Randomized trial demonstrates superior fluid absorption with superabsorbent dressings compared to foam dressings in skin-graft donor sites, suggesting enhanced exudate management.

Key Points

  • To compare fluid absorption performance, wound epithelialization, pain outcomes, and complication rates between superabsorbent and foam dressings at split-thickness skin-graft donor sites.
  • Randomized controlled trial enrolling 30 patients undergoing split-thickness skin grafting, with zero exclusions or loss to follow-up.
  • Each donor site was divided into two equal zones, randomly allocated to receive either a foam dressing or a superabsorbent dressing.
  • Outcomes including fluid absorption, wound epithelialization, pain scores, and complications were evaluated at 3-day intervals through postoperative day 15, alongside benchtop absorption testing.
  • Superabsorbent dressings showed significantly higher clinical fluid absorption than foam dressings on day 3 (104.09 vs. 71.87 mg/cm²/day; p = 0.034), day 6 (84.45 vs. 40.91 mg/cm²/day; p < 0.001), and day 9 (76.59 vs. 19.74 mg/cm²/day; p = 0.022).
  • Benchtop testing showed a 10 × 10 cm superabsorbent dressing weighed less (5.5 g vs. 7.5 g) and absorbed more saline (93 mL vs. 75 mL) than the foam equivalent.
  • Wound epithelialization was comparable between groups with no observed infections, allergic reactions, or complications, while pain scores trended lower with superabsorbent dressings on days 6 and 9 without reaching statistical significance.
