Abstract
BACKGROUND: The International Committee of the Red Cross (ICRC) implemented the Red Cross wound classification (RCWC) to quickly assess the severity of a wound in conflict settings. A subdivision into wound grades derived from the RCWC consists of grades 1, 2, and 3, and represents low, major, and massive energy transfer, respectively, to the injured tissue. The aim of this observational study is to assess whether the Red Cross wound grade of a pediatric patient's wound correlates with patient outcomes.Entities:

Red Cross wound classification [11]
| Wound feature | Definition |
|---|---|
| E (entry) | Estimate the maximum diameter of the entry wound in cm |
| X (exit) | Estimate the maximum diameter of the exit wound in cm (X = 0 if no exit) |
| C (cavity) | Can the “cavity” of the wound take two fingers (finger width) before surgery? |
| F (fracture) | |
| V (vital structure) | Is the brain, viscera, or major vessels injured? |
| M (metallic body) | Bullet or fragments visible on X ray? |
V = N, T, and A are subcategories of central wounds; V = H is a subcategory of wounds of the limbs
Wound grades derived from the Red Cross wound classification [11]
| Skin defecta | Cavity | Fracture | |
|---|---|---|---|
| Grade 1 | < 10 cm AND | Absent AND | Absent or simple fracture |
| Grade 2 | < 10 cm AND | Present OR | With clinically significant comminution |
| Grade 3 | ≥ 10 cm AND | Present OR | With clinically significant comminution |
aSkin defect: size of entry and exit wound combined
