Time to re-epithelialisation Cox regression (hazard ratios) n = 233.
| Variable | Sub-group | Hazard ratio (95% CI) | p value |
|---|---|---|---|
| TBSA | 0.97 (0.93–1.01) | 0.150 | |
| Burn depth | DDPT | 0.52 (0.39–0.67) | < 0.001 |
| SPT | 1 | ||
| Debridement sub-group | Ketamine in the ED | 0.39 (0.21–0.72) | < 0.001 |
| Other | 0.51 (0.33–0.78) | 0.001 | |
| OT within 24 h | 1 |
NB: All grafted patients N = 59, were excluded from this analysis.
DDPT deep dermal partial thickness, SPT superficial partial thickness, TBSA total body surface area, ED emergency department, OT operating theatre, CI confidence interval.
