The experimental study of the irrigating pressure of firearm injury / 医疗卫生装备

ABSTRACT

Objective:In order to reduce the incidence of infection and disablement,and increase the efficiency of wound flushing and debriding,the irrigating pressure of firearm wound was designed.Methods Canine models wounded with gunshot at the limbs were established.Two irrigating methods,including meddling irrigating pressure and high irrigating were used to irrigating wound,respectively.General observation,optical microscopy and quantitative bacterial analysis were performed immediately after injured and irrigated.Results The bacteria counts after irrigating on the surface of wound are much less than those before irrigating in two groups(p
