Abstract：Objective To analyze the cause of abdominal distension in patients after aortic valve replacement and to compare the effect of different gastrointestinal decompression methods.Methods (1)The clinical data of patients after aortic valve replacement from Jan 2015 to Jan 2017 were collected and analyzed to find the cause of abdominal distension by Multivariate logistic regression.(2)The patients with moderate or severe abdominal distension from the first study section,who needed gastrointestinal decompression,were chosen and randomly divided into 2 groups according to different gastrointestinal decompression methods.Patients in the A group were given the small intestine decompression tube,and patients in the B group were given the stomach tube.The effect and time of abdominal distension relief were compared between 2 groups.Results (1)There were 132 patients with abdominal distension after aortic valve replacement (132/498,26.5％).Multivariate logistic regression shows the continuous time of sedatives/muscle relaxants ≥ 72 h was the independent risk factor for abdominal distension.(2)The abdominal distension relief rate was 78.8％(41/52) and the relief time was (46.9±18.6)h in the A group.The abdominal distension relief rate was 58.8％(30/51) and the relief time was (55.2±21.4)h in the B group.There was significant difference on the relief rate and time between 2 groups,and the A group was better.Conclusion The continuous time of sedatives/muscle relaxants ≥72 h is the independent risk factor for abdominal distension in patients after aortic valve replacement.The small intestine decompression tube is better than the stomach tube for patients who need gastrointestinal decompression after aortic valve replacement.
