RESUMO
OBJECTIVE: To verify the effects of treatment with blood transfusion and scopolamine on severe chlorphenamidine poisoning (SCP). METHODS: 400 patients with severe oral chlorphenamidine poisoning were randomly divided into two groups. 200 patients (Group I) were treated with the traditional combined therapy including gastrolavage, purgation and taking redox agent (methylene blue and vitamin C) while the other 200 patients (Group II) in addition to the above mentioned therapy, received blood transfusion and scopolamine injection. RESULTS: The cure rate of Group II was 99.5% and significantly higher than that of Group I (91.0%, P < 0.01). The average time of improving in health in Group II [(8.71 +/- 1.49) h] was obviously shorter than those in Group I [(10.65 +/- 1.72) h, P < 0.01]. Blood methemoglobin concentrations in Group II at 3, 7, 12, 24 h after admission [(43.58 +/- 2.69), (34.21 +/- 2.30), (20.60 +/- 4.03), (13.50 +/- 1.65) g/L respectively] were obviously lower than those in Group I [(54.42 +/- 12.79), (42.17 +/- 22.34), (30.66 +/- 17.67), (19.01 +/- 0.61) g/L respectively, P < 0.01]. CONCLUSION: Blood transfusion and scopolamine had distinctive therapeutic effect on SCP to makeup the deficiency of redox agent. Combination of three therapies may potentiate the detoxication for chlorphenamidine.
