腹腔内感染最常发生于贯穿性或闭合性腹部创伤或穿孔性阑尾炎等中。胃肠内细菌溢入腹腔导致腹膜炎、局限性腹腔脓肿阳继发性败血症。这些感染大部分由多种细菌所引起,直接与胃肠道不同水平的内源性特异菌群有关。其治疗主要为及时的外科手术,并应用抗生素以减少细菌的局部入侵或败血症的发生机会。在获得细菌培养和药敏报告以前选用适宜抗生素,主要取决 Intraperitoneal infections most often occur in penetrating or closed abdominal trauma or perforation appendicitis. Gastrointestinal bacteria overflow into the abdominal cavity leading to peritonitis, localized abdominal abscess secondary positivity sepsis. Most of these infections are caused by a variety of bacteria, directly related to different levels of endogenous specific flora of the gastrointestinal tract. The treatment is mainly for timely surgery, and the application of antibiotics to reduce the chance of local invasion of bacteria or sepsis. The choice of appropriate antibiotics before obtaining bacterial culture and drug susceptibility reports is largely up to date
