目的

探讨抗凝血杀鼠剂中毒患者维生素K1的维持剂量治疗的相关因素。

方法

收集2013年1月至2014年10月36例抗凝血杀鼠剂中毒患者的数据资料,检测并分析维生素K1使用量与抗凝血杀鼠剂种类及具体毒检剂量,凝血酶原活动度(PTA),凝血酶原时间(PT),活化部分凝血活酶时间(APTT),患者院前时间及住院时间的相关性,并对相关因素进行多因素稳健回归分析。

结果

经Spearman秩相关分析发现,溴鼠灵与维生素K1用量呈正相关(r=0.356,P<0.05);PTA、住院时间及院前时间与VK1用量呈负相关(r=-0.325、-0.420、-0.407,P均< 0.05)。而PT、APTT及溴敌隆与维生素K1用量无明显相关性(r=0.295、-0.312、0.192,P均> 0.05)。多因素稳健回归分析发现,稳定出凝血功能后,院前时间[95%置信区间:(-0.536,-0.103),P=0.002]及住院时间[95%置信区间:(-1.955,-0.248),P=0.013]对维生素K1维持剂量有明显影响。

结论

稳定出凝血功能后,给予维生素K1持续治疗的患者,随着时间的延长,所需维生素K1的维持剂量逐渐减小,与中毒种类及毒物浓度无关。

Objective

To investigate the effect factors of Vitamin K1 maintenance dose in patients with anticoagulant rodenticide poisoning.

Methods

This retrospective study was analyzed 36 cases in our hospital from January 2013 to October 2014. The correlation between Vitamin K1 and types of anticoagulant rodenticide and toxic dose, prothrombin time activity (PTA), prothrombin time (PT), activated partial thromboplastin time (APTT), prehospital duration (from poisoning to hospitalization), and length of hospital stay (duration of Vitamin K1 treatment) were collected and analyzed by Spearman rank correlation analysis and multivariate regression analysis.

Results

The dose of Vitamin K1 was positively correlated with brodifacoum (r=0.356, P<0.05), negative correlated with PTA, prehospital duration and length of hospital stay (r=-0.325, -0.420, -0.407, all P<0.05). However, there were no significant correlation between dose of Vitamin K1 and PT, APTT, bromadiolone (r=0.295, -0.312, 0.192, all P>0.05). The multivariate regression analysis also showed that prehospital duration [95% confidence interval: (-0.536, -0.103), P=0.002] and length of hospital stay [95% confidence interval: (-1.955, -0.248), P=0.013] had significant effect on the maintenance dose of vitamin K1 in the patients with coagulation function stable.

Conclusion

After stabilizing the coagulation function, the demanded maintenance dose of vitamin K1 can be gradually decreased with time prolonged, and have no relationship with type of anticoagulant rodenticide and toxic dose.
