Study on the Difference in Effect and Safety Between Dimethyl Ether and Liquid Nitrogen in the Clinical Application of Treating Common Warts
Abstract
cryogen in the treatment of common warts, a double-blind, randomized controlled clinical study was designed. 200 patients with common
warts were included and randomly divided into two groups (dimethyl ether group and liquid nitrogen group). They received dimethyl ether
spray and liquid nitrogen cryotherapy, respectively, and the efficacy, pain score, adverse reaction rate and recurrence rate were observed. The
research data showed that there was no significant difference in the complete cure rate between the spray group and the liquid nitrogen group
(85% vs. 88%, P > 0.05), but the pain score (2.10.8 vs. 4.51.2, P<0.01) and adverse reaction rate (12% vs. 25%, P<0.01) of the dimethyl
ether group were significantly lower than those of the liquid nitrogen group. There was no significant difference in the recurrence rate between
the two groups (5% vs.7%, P>0.05). The following conclusions can be drawn from this study: The efficacy of dimethyl ether spray is comparable to that of liquid nitrogen cryotherapy, but it has higher safety and patient compliance, and is suitable as an alternative to liquid nitrogen
cryotherapy, especially in primary care and home treatment scenarios.
