问题 在胺碘酮抗心律失常过程中,为保证药物浓度在合适范围,可间接测定rT浓度使其保持在
选项 A.<42ng/dl B.>100ng/dl C.比自身值升高3倍以上 D.42~77ng/dl E.77~100ng/dl
答案 D
解析 :在胺碘酮抗心律失常过程中,T和rT明显增高,T减低。血清rT在42~77ng/dl之间,则表示胺碘酮剂量合适;<42ng/dl,则剂量不足;>100ng/dl或比自身值升高3倍以上,则可能引起中毒反应。

错误啦!

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
