Abstract:
Objective To investigate the clinical effect of 595 nm tunable pulsed dye laser (PDL) in treating fresh trauma scars.Methods 85 patients had been selected,of which,117 sites were treated with a 595 nm tunable PDL one time or two times at a fluence of 7-15 J/cm2 and pulse widths of 1.5-3 ms,7 mm spot size.Nursing skill of burn wound was also used on treatment area after laser treatment.Scars were evaluated for melanin,height,vascularity and pliability using the Vancouver Scar Scale (VSS) before treatment and after the last treatment 8weeks.Results Total score of 117 sites decreased from (8.30 ± 2.63) to (2.70 ± 1.25),melanin decreased from (1.60 ± 0.84) to (0.60 ± 0.97),height decreased from (1.30 ± 0.82) to (0.40 ± 0.51),vascularity decreased from (2.40 ± 0.52) to (0.40 ±0.52),pliability decreased from (2.80 ± 1.32) to (1.30 ±0.48),with statistical significance between before treatment and after treatment (P ＜ 0.05).Conclusions 595 nm tunable pulsed dye laser appears to have a beneficial clinical effect on patient's fresh trauma scar.
