A patient is reported in whom an intravenous bolus injection of 50 mg lignocaine produced extreme sinus bradycardia (rate 14 to 20/min). Only 2 patients with such a response to a similarly small dose have been previously reported, but these reports indicate clearly that careful electrocardiographic monitoring is advisable when lignocaine is administered.
据报道,一名患者静脉推注50毫克利多卡因后出现极度窦性心动过缓(心率14至20次/分钟)。此前仅报道过2例对同样小剂量有这种反应的患者,但这些报道清楚地表明,使用利多卡因时建议进行仔细的心电图监测。
