[Management strategy of intra-abdominal infection caused by multidrug-resistant bacteria].

Most of the intra-abdominal infections are benign and critical diseases caused by trauma, surgery and gastrointestinal diseases, which require the attention of surgeons. The increase of drug resistance of pathogens is a common clinical problem. The intra-abdominal infection caused by multidrug-resistant bacteria is a huge challenge faced by clinicians, and is mainly found in hospital-acquired abdominal infections, of which gram-negative bacteria are the most common. This paper firstly summarizes the common types, early diagnosis and risk factors of multidrug-resistant bacteria according to the literature, and then describes the treatment strategy of intra-abdominal infection caused by multidrug-resistant bacteria from four aspects: anti-infective medication, infection source control, resuscitation and organ support, and nutritional support treatment. In addition, we should promote gastrointestinal function recovery through nutritional support treatment and prevent intestinal source infection, on the basis of understanding the risk factors of multidrug-resistant infection, rational use of anti-infective medication and infection source control measures. At the same time, proper organ function support can help to improve the success rate in the treatment of multidrug-resistant intra-abdominal infection.
