Clinical value of 2940 nm erbium pixel laser with hydrocolloid dressing and ice compress in the treatment of acne scar / 中华医学美学美容杂志

ABSTRACT

Objective To observe the effect of hydrocolloid dressings with instant ice compress on the healing process,postoperative pain and efficacy of patients with acne scar treated by 2940 nm erbium pixel laser.Methods We selected 60 patients with acne scar from November 2012 to June 2014 treated by the erbium pixel laser.They were randomly divided into two groupshydrocolloid dressings with ice compress after treatment were used in observation group (n=37)and postoperative wound dry were kept in control group (n=23);pain,duration of burning,erythema duration,efficacy,decrustation time,postoperative complications were evaluated and quantitatively analyzed.Results Compared with the control group,the application of hydrocolloid dressings with ice compress group (observation group) received less postoperative paim postoperative VAS pain score was (5.81± 0.64) in observation group and (6.09±0.69) in control group;duration of burning was shorter(1.86± 0.75) h in observation group and (3.65±0.93) h in control group;duration of erythema was shorter(2.27±0.73) d in observation group and (3.52 ±0.79) d in control group;decrustation time was shorter(5.76± 1.06) d in observation group and (8.09±0.95) d in control group;postoperative complications were reduced(5.4％,2/37) in the observation group and (30.4％,7/23) in the control group,with statistically significant difference (all P＜0.05).The differences were not statistically significant in the intraoperative VAS score and the curative effect.Conclusions The application of hydrocolloid dressing with instant ice compress after erbium pixel laser in the treatment of acne scar can effectively reduce postoperative pain and burning sensation,shorten the duration of erythema and crusting time after operation.It also reduces the incidence of complications.
