影响电击除颤效果的因素分析

Influential Factors of Defibrillation in Patients with Ventricular Fibrillation

目的分析影响心室颤动(VF)电击除颤效果的因素,提高VF的救治质量。方法对本院2001年1月至2010年1月收治的VF患者206例进行分析,比较电击除颤成功组与失败组年龄、VF持续时间、VF振幅、VF频率、除颤次数、胺碘酮用量、肾上腺素用量。结果 VF电击除颤成功组与失败组在年龄、除颤次数上比较差异无统计学意义(P>0.05)。在VF振幅、VF频率、VF持续时间、胺碘酮、肾上腺素用量方面比较差异有统计学意义(P<0.05)。结论 VF振幅、频率及持续时间决定电击除颤时机,正确把握才能保证电击除颤效果。合理应用胺碘酮、肾上腺素可以提高电击除颤成功率。

Objective To analyze several factors of defibrillation in the patients with ventrieular fibrillation （VF）. Methods 206 VF eases on our hospital from Janaury 2001 to Janaury 2010 were analyzed. VF duration, VF amplitude, VF frequency, the number of defibrillation, dosage of amiodarone and adrenaline was compared between sueeess and failure group of VF. Results There was no significant difference in age and number of previous defibrillation between the two groups （ P 〉 0.05 ）. There was significant difference in VF amplitude, VF frequency,VF duration, dosage of amiodarone and adrenaline （ P 〈 0. 05 ）. Conclusions The achievement of defibrillation was related to amplitude, frequency and duration of VF. The using of amiodarone and epinephrine properly can improve the success rate of defibrillation.
