目的：观察尼莫地平对氟乙酰胺中毒患儿血钙的影响。方法：将７２例氟乙酰胺中毒患儿随机分为治疗组和对照组，治疗组除常规治疗外加用尼莫地平 １．５ｍｇ／ｋｇ／ｄ分３次口服或鼻饲，并测定治疗前后血钙。结果：治疗组治疗后血钙明显高于对照组，两组比较有显著差异。结论：尼莫地平佐治氟乙酰胺中毒可以抑制钙离子内流，使血钙升高，减轻对神经系统损害。 Objective: To observe the effect of nimodipine on serum calcium in children with fluoroacetamide poisoning. Methods: Seventy-two children with fluoroacetamide intoxication were randomly divided into treatment group and control group. The treatment group was treated with nimodipine 1.5mg / kg / d orally or nasally for 3 times in addition to routine treatment, and the serum calcium . Results: After treatment, the blood calcium level of the treatment group was significantly higher than that of the control group, with significant differences between the two groups. Conclusion: Nifedipine treatment with fluoroacetamide can inhibit the influx of calcium, increase the serum calcium and reduce the nervous system damage.
