To explore the effect of hydrogel combined with silver alginate dressing in the treatment of deep partial thickness burn on the face.

A total of 82 patients with deep partial thickness burn treated in the Department of Burns and Wound Repair, People′s Hospital of Xinjiang Uygur Autonomous Region from February 2017 to February 2020 were selected and randomly divided into intervention group and control group according to the random number table method, with 41 patients in each group. Before treatment, patients in both groups were treated with inactivated wound tissues removed according to clinical operating specifications, and the wounds were rinsed with 0.9% sodium chloride solution and dried with sterile gauze. The control group was given the silver sulfadiazine cream to be rubbed into sterile petrolatum oil gauze, made into a "mask" dressing and attached to the patient′s face for treatment, and the dressing was changed once a day. The intervention group selected the required dosage of the hydrogel dressing according to the amount of exudation from the wound of the patient, and applied it evenly to the wound, and cut the silver alginate dressing (0.5 cm larger than the outer edge of the wound) according to the size of the wound to make it completely covered and attached to the wound, the frequency of dressing change was determined according to the wettability of the outer silver alginate dressing, and the dressing was changed once every 5 to 7 days. Observed whether there were adverse reactions, the number of dressing changes, the average visual analogue scale (VAS) score and the average treatment cost of the two groups of patients during the treatment period. The patients were followed up 6 months after discharge from the hospital, the effective rate of treatment was evaluated according to the degree of scar hyperplasia and pigmentation after wound healing, and the total effective rate of treatment for the two groups of patients was calculated. Data were compared with t test and rank sum test.

Patients in the two groups were cured by dressing change, and there were no serious local infections and other serious systemic adverse reactions during the treatment. The number of dressing changes, the average VAS score, and the average treatment cost of the intervention group were (4.8±0.7) times, (4.5±0.8) minutes, (2 013.6±190.7) yuan, and compared with the control group [(23.0±1.2) times, (6.3±0.7) points and (3 523.5±223.4 yuan), the difference was statistically significant (t=86.866, 11.992, 34.868; P<0.05). Patients were followed up in the outpatient clinic for 6 months after discharge, in the intervention group, 29 cases were excellent (70.7%), 10 cases were good (24.4%), 1 case was moderate(2.4%) and 1 case was poor (2.4%), the total effective rate of treatment was 95.1%; in the control group, 17 cases were excellent (41.5%), 16 cases were good (39.0%), 3 cases were moderate(7.3%) and 5 cases were poor (12.2%), the total effective rate of treatment was 80.5%. The total effective rate of treatment between the two groups was compared, and the difference was statistically significant (Z=2.817, P=0.005).

Hydrogel combined with silver alginate dressing can relieve patients′ pain, reduce the frequency of dressing changes, reduce the average treatment cost, reduce scar formation and pigmentation after wound healing, and is suitable for the treatment of deep partial thickness burn on the face.
