Randomized Controlled Trial[Clinical effects of vacuum sealing drainage in the treatment of alkali burn wounds].
Objective: To preliminarily observe the clinical effects of vacuum sealing drainage (VSD) in the treatment of alkali burn wounds. Methods: From June 2016 to March 2020, 60 male patients with alkali burns who met the inclusion criteria and hospitalized in the Affiliated Hospital of Jiangnan University were recruited in this prospectively randomized control study. According to the random number table, silver sulfadiazine group and VSD group were both allocated with 30 patients, aged (36±8) and (35±10) years respectively; with total burn area of (7.2±2.0) % and (8.5±3.0) % total body surface area respectively. ⋯ On treatment day 7, the volume of drainage fluid of patients in VSD group was (21±8) mL, which was significantly lower than (149±44) mL of exudate of patients in silver sulfadiazine group (t=-12.61, P<0.01). (2) After 7, 14, and 21 days of treatment, the wound healing rates of patients in VSD group were (39±6) %, (74±10) %, and (92±3) %, respectively, which were significantly higher than (25±3) %, (59±6) %, and (77±6) % in silver sulfadiazine group (t=7.07, 5.59, 7.09, P<0.01). (3) Before treatment, the serum levels of TNF-α and IL-8 of patients in the two groups were similar. After 7 days of treatment, the serum levels of TNF-α and IL-8 of patients in VSD group were significantly lower than those in silver sulfadiazine group (t=-8.75, -8.04, P<0.01). (4) The pain score during dressing change and medical cost of patients in VSD group were significantly lower than those in silver sulfadiazine group (t=-4.28, -7.56, P<0.01), while the discharge satisfaction score of patients in VSD group was significantly higher than that in silver sulfadiazine group (t=10.91, P<0.05). Conclusions: The application of VSD technology in clinical alkali burn wounds can effectively promote the removal of residual lye, alleviate the further damage of lye to skin tissue, shorten the wound healing time, effectively remove inflammatory mediators, reduce the pain of dressing change, decrease the total cost of treatment, and enhance satisfaction of patient.
