To explore the clinical effects of lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine (Fuchunsan) on the treatment of postburn hyperplastic scar.
Sixty-three patients with hyperplastic scar after burn injury hospitalized from February 2012 to June 2014 in our department were treated with lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine (Fuchunsan). Patients were divided into early stage group (E, n = 35), middle stage group (M, n = 25), and late stage group (L, n = 3) according to the formation time of scar, which was respectively 3 weeks to 3 months, longer than 3 months and less than or equal to 6 months, and 3 to 15 years in groups E, M, and L. The number of times of laser treatment of patients in each group was recorded. The degree of scar pain in patients of the three groups was assessed by the Numerical Rating Scale (NRS) before treatment and after treatment for 1, 2, and 3 times. The scar condition of patients in groups E and M was assessed by the Vancouver Scar Scale (VSS) before treatment and after treatment for 1, 3, and 5 times. Patients in group L did not receive VSS assessment but were evaluated by clinical observation only. Photos of scar in treating area were taken before treatment and after treatment for 3 and 5 times to evaluate the clinical effect. Data were processed with t test.
Patients in groups E and M were treated with laser for (4.8 ± 1.1) and (7.7 ± 2.1) times respectively. In group L, the treatment was stopped in 2 patients after laser treatment for 5 times, and 1 patient received laser treatment for 12 times. The degree of pain in patients of groups E and M was alleviated significantly after treatment for one time, and the number of patients scoring 1-4 point (s) in NRS increased from 5 cases to 38 cases. After treatment for 2 and 3 times, the increase in the number of patients scoring 1-4 point (s) in NRS was on a small scale. Before treatment and after treatment for 1 time, VSS scores of patients in groups E and M were similar (with t values respectively 0.641 and 0.082, P values above 0.05). After treatment for 3 and 5 times, VSS scores of patients in group E were respectively (9.2 ± 0.8) and (7.0 ± 1.1) points, which were significantly lower than those in group M [(9.7 ± 1.0) and (8.2 ± 1.0) points, with t values respectively -1.993 and -4.433, P < 0.05 or P < 0.01]. After treatment for 3 times, the rate of improvement in appearance was respectively 88.6% (31/35) and 72.0% (18/25) in groups E and M, and it was respectively 100.0% (35/35) and 96.0% (24/25) after treatment for 5 times. No significant effect in appearance was found in the 3 patients in group L.
Early application of lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine (Fuchunsan) for the treatment of postburn hyperplastic scar is effective.
