RESUMEN
OBJECTIVE: To study the safety of using Chinese drugs for breaking blood expelling stasis (CDBBES) in hypertension patients with intracerebral hemorrhage within 6 h, and to observe whether they would result in hematoma enlargement. METHODS: A prospective randomized double-blind controlled clinical study was employed. Totally 128 cerebral hemorrhage patients within 6 h were recruited from 8 research centers from October 2013 to March 2015, and finally 76 of them were included. These patients were assigned to 3 groups by simple random sampling, group A, B, and C. Patients in group A (26 cases) took whole CDBBES recipe (containing leeches and equivalent insects). Those in group B (25 cases) took CDBBES recipe (removing leech and gradfly). Those in group C (25 cases) took placebos. Medication lasted for 10 successive days. The hematoma enlargement rate within 24 h, the occurrence of adverse reactions and adverse events were observed. To guarantee the safety of this trial, an interim analysis of first level unblinding was used. RESULTS: The hematoma enlargement rate was 11. 5% (3/26) in group A, 16. 0% (4/25) in group B, and 20. 0% (5/25) in group C. There was no statistical difference in the hematoma enlargement rate among the 3 groups (X² =0. 823, P =0. 682). Adverse reactions and adverse events occurred in 7 cases, 1 patient with acute myocardial infarction, 1 with chest op- pression and palpitation, 2 with diarrhea in group A. No patient had adverse reaction or adverse event in group B. And diarrhea occurred in 3 patients of group C. CONCLUSION: The interim analysis of first level unblinding showed that hematoma enlargement within 6 h was not resulted from using CDBBES.
