Observational Study
Contaminated wounds: Effectiveness of debridement for reducing bacterial load.
Hand Surgery and Rehabilitation 2016 September
Surgical management of contaminated hand wounds may seem anecdotal, but such injuries actually account for an appreciable amount of the activity in emergency hand centers, and recommendations put forward by scientific societies differ. Dealing effectively with this public health issue calls for clarifying the usefulness of the various available treatments. Our study's objective was to determine the effectiveness of surgical debridement. In this prospective study, 92 patients with contaminated hand wounds underwent surgical debridement. Selection criteria included the length of time between injury and treatment, and the mechanism of injury. Patients with infected wounds, those treated by antibiotics, who were immunosuppressed or had osteoarthritis were excluded. Skin samples were collected both before and after debridement. In 62% of cases, the wounds were contaminated before debridement. Following the procedure, 87% of the bacterial smears were negative. The comparison between debridement and smear results was statistically significant (Student's t test, P<0.001). Surgical debridement, with appropriate irrigation, can effectively eradicate bacterial flora due to contamination.
