Cardiac Arrest after Intraurethral Administration of Lidocaine

尿道內施用lidocaine後産生心臟停止跳動

並列摘要


We report a case of cardiac arrest immediately following intraurethral administration of lidocaine as topical anesthesia for cystourethroscopy in an 87-year-old man. Intraurethral mucosa lesions from previous attempts at Foley catheter insertion led to a rapid elevation in the blood concentration of lidocaine. In the presence of such factors as a urethral obstruction and a high lidocaine concentration signs of cardiovascular toxicity can occur almost simultaneously with those of central nervous system toxicity We therefore recommend that spinal or general anesthesia may be better for patients with intraurethral mucosa lesions undergoing urethral procedures.
