Plasma concentrations of lidocaine were measured over a period of three hours following the instillation of lidocaine jelly (Xylocaine 2% Jelly) into the genitourinary tract of 30 patients (15 male, 15 female) scheduled for cystoscopy. The mean quantity of jelly instilled was 21.4 Gm (11-27.5 Gm) and of lidocaine HCl administered thereby 428 mg (218-550 mg). Plasma concentration reached measurable levels in only 5 cases, never exceeding 0.2 microgram/ml.
对30例计划进行膀胱镜检查的患者(15例男性,15例女性)在泌尿生殖道内注入利多卡因凝胶(赛罗卡因2%凝胶)后三小时内测定血浆利多卡因浓度。注入凝胶的平均量为21.4克(11 - 27.5克),由此给予的盐酸利多卡因平均量为428毫克(218 - 550毫克)。血浆浓度仅在5例中达到可测量水平,从未超过0.2微克/毫升。
