Observation on cleaning and curative effect of ultrasonic debridement machine in cleaning the postoperative surface of wound of perianal abscess / 中国医学装备

ABSTRACT

Objective:To investigate the effect of ultrasonic debridement machine for postoperative cleaning of perianal abscess.Methods:77 patients with perianal abscess were enrolled in this study.They were divided into control group (38 cases) and observation group (39 cases) by random sampling.The control group was implemented routine treatment post operation and the observation group was implemented routine dressing combined with ultrasonic cleaning machine to clean the crissum.And the visual analogue scale (VAS) was adopted to analyze the pain level of postoperative wound.And the postoperative clearance rate of bacteria, wound healing time, controlled time of infection and cleaning effect of wound between two groups were compared.Results:The VAS score of the observation group on the 1st, 3rd, 5th and 9th day after operation were significantly lower than those of control group (t=8.031, ■on wound of observation group was significantly higher than that of control group while the length stay in hospital of■healing time and controlled time of infection of observation group were significantly lower than those of control group■machine to clean wounds after perianal abscess surgery can effectively remove bacteria of wound, and improve cleaning effect, alleviate pain level of wound, and promote the rapid repair of wounds.
