人体遭受创伤之后,由于许多因素的相互作用,能使损伤加重,其中包括失去生机的组织、出血、局部血流阻断、异物进入体内,以及致病微生物污染伤口等。组织一旦失去生机,其蛋白和血液常常是微生物生长的良好培养基,能加快感染形成,而感染又可促进组织坏死。眼内炎的诊断问题造成眼部创伤感染因素很多,归纳起来可分为三方面:致病微生物;创伤处理不当;伤员体质。一、致病微生物 (一)细菌影响感染的因素有三,一细菌来源;二、细菌数量;三、细菌毒力。 1.细菌来源:可从伤口进入,众所周知,眼睑、睫毛、结膜囊内有许多种附生菌,一旦创伤,这些细菌即可进入眼组织。致伤物本身表面亦可有 Following trauma to the human body, damage can be exacerbated by a combination of factors, including loss of vital tissue, bleeding, partial blood flow blockage, foreign body ingress into the body, and pathogenic microorganisms contaminating the wound. Once a tissue loses its vitality, its protein and blood are often good media for microbial growth, which speeds up the formation of infection, which can in turn promote tissue necrosis. The diagnosis of endophthalmitis caused by eye trauma infection many factors, can be summed up in three aspects: the pathogenic microorganisms; improper trauma; wounded physique. First, the pathogenic microorganisms (A) of the bacteria affect the infection of three, a source of bacteria; Second, the number of bacteria; Third, bacterial virulence. 1. Bacterial Source: From the wound to enter, we all know, eyelids, eyelashes, conjunctival sac there are many kinds of bacteria, once the trauma, these bacteria can enter the eye tissue. The wound itself may have surface
