Abstract：Objective To analyze the effect and safety of computed tomographic enteroclysis with air with different air injection volume.Methods Totally 47 patients undergoing computed tomographic enteroclysis with air from January 2013 to June 2015 were randomly divided into 1.2 L group (12 cases), 1.5 L group (12 cases),1.8 L group (12 cases) and 2.0 L group (11 cases) given different air injection volume.The filling degree of small intestine, patient discomfort degree and incidence of adverse reactions were compared between groups.Results The filling degree of small intestine was significantly different among 4 groups [1.2 L group : 2 cases of 1 score, 6 cases of 2 scores, 4 cases of 3 scores;1.5 L group: 2 cases of 2 scores, 7 cases of 3 scores, 3 cases of 4 scores;1.8 L group: 1 case of 2 scores, 3 cases of 3 scores, 8 cases of 4 scores;2.0 L group: 1 case of 2 scores, 3 cases of 3 scores, 7 cases of 4 scores] (P ＜ 0.01);the filling degrees of small intestine in 1.8 L group and 2.0 L group were significantly better than that in 1.2 L group (P ＜ 0.01).The patient discomfort degree was not significantly different among 4 groups (P ＞ 0.05).The abdomianl distention occurred in 2 cases in 1.2 L group, 3 cases in 1.5 L group, 3 cases in 1.8 L group and 5 cases (45.5％) in 2.0 L group;the nausea occurred in 1 case in 1.5 L group, 2 cases in 1.8 L group and 3 cases in 2.0 L group.Conclusion In computed tomographic enteroclysis with air, the small intestine filling degree gets better with increasing of air injection volume, but the incidence of adverse reactions is also increased;suitable air injection volume should be chosen according to the needs and patients' response.
