Objective To evaluate the curative effect of Keli-Paoxi power for the treatment of acute paronychia. Methods A total of 144 patients with acute paronychia were randomly divided into a Keli-Paoxi power group, a mupirocin ointment group and an ethanol soaking group, 48 in each group. All patients were treated for 3 weeks and followed-up for 2 months. The time to regression of redness and swelling in the nail groove was recorded. The Visual Analogue Scale (VAS) was used to assess tenderness. The curative effects were evaluated, and recurrence of paronychia was recorded. Results The time to regression of redness and swelling in the nail groove in the Keli-Paoxi power group (2.2 ± 0.6 d) was significantly shorter than that in the mupirocin ointment group (8.1 ± 1.7 d) or ethanol soaking group (7.9 ± 1.2 d; F=344.597, P<0.01). The VAS Scores in the Keli-Paoxi power group (1.2 ± 0.2) was significantly lower than that in the mupirocin ointment group (3.2 ± 0.3) or ethanol soaking group (3.1 ± 0.3; F=831.273, P<0.01). The total effective rate in the Keli-Paoxi power group (100.0%, 48/48) was significantly higher than that in the mupirocin ointment group (83.3%, 40/48) or ethanol soaking group (81.3%, 39/48; χ2=9.700, P=0.008). The recurrence rate of paronychia in the Keli-Paoxi power group (2.1%, 1/48) was significantly lower than that in the mupirocin ointment group (16.7%, 8/48) or ethanol soaking group (14.6%, 7/48; χ2=6.000, P=0.049) at 2 months follow-up. Conclusions Keli-Paoxi power can alleviate tenderness, shorten the time to regression of redness and swelling in the nail groove, decraese recurrence in patients with acute paronychia. The curative effect of Keli-Paoxi power is superior to mupirocin ointment and ethanol soaking in the treatment of acute paronychia.
