ObjectiveTo observe the prophylactic effects of senna extract 40 mg/kg on chemotherapy-induced constipation.MethodsEighty-two patients suffering from constipation after chemotherapy were assigned to Group AB and Group BA. Group AB referred to patients who first took senna extract in the 1st chemotherapeutic course and the crude fiber diet in the 2nd chemotherapeutic course. But the sequence was just the opposite in Group BA. The effective rates of relieving chemotherapy-induced constipation by senna extract and by the crude fiber diet were observed. The differences of the digestive tract reaction and the hematotoxicity reaction were compared. The conditions of patients' abdominal pain and stool properties were observed after they took senna extract.ResultsThe effective rate of constipation by taking senna extract was 92.68% and that by the crude fiber diet was 10.93%, with statistical difference shown (P < 0.01). There was no statistic difference in adverse reaction rate such as decreased neutrophils over degree II, decreased hemoglobin, decreased platelet, nausea, vomit, etc. (P > 0.05). The occurrence rate of abdominal pain over degree II after taking senna was 8.54%. In the distribution of stool properties, the rate of loose stool was 35.53%.ConclusionSenna extract 40 mg/kg was effective and safe in treating chemotherapy-induced constipation.
