ObjectiveTo explore the correlation of gastrointestinal symptom of severe cases and abdominal compartment syndrome (ACS),improve monitor technique. MethodsUsing descriptive study to do classified description according to the distribution of 384 severe cases' gastrointestinal symptom and using regressive analysis to analyze the dangerous factors of 46 cases who suffered ACS. Results①The rate of gastrointestinal symptom of 46 cases with ACS:one case with nausea and vomiting occupied 2.2％ ,45 cases with abdominal distension and pain occupied 97.8％ ,45 cases with bowel sound occupied 97.8％,2 cases with diarrhea occupied 4.3％,45 cases with constipation occupied 97.8％. ②Aceording to the single factor logistic regressive analysis shows statistical significant symptoms relating to ACS as follows:abdominal distension and pain,bowel sound decline and constipation,etc. With multi-factors unconditional progressively logistic regressive analysis shows:the first dangerous factor of ACS is abdominal distension and pain(OR=259.106),then is bowel sound decline. CondusionThe correlation exists between the gastrointestinal symptoms and ACS. The clinical nurses should pay attention to the monitor of gastrointestinal function so that the incidence of ACS can be reduced through promoting monitor skills.
