笔者通过对15例不能手术肺癌患者支气管动脉灌注顺铂的血药浓度监测,对靶器官及周围组织的血药浓度——时间曲线进行了分析。结果表明,在支气管动脉灌注过程中,靶器官的血药浓度明显高于周围组织的血药浓度,且靶器官的血药浓度大大超过了顺铂的有效抗癌浓度,为支气管动脉灌注治疗肺癌提供了可靠的理论依据,并对灌注过程中应注意的事项进行了分析,对于指导临床治疗具有重要意义. The author of 15 cases of patients with lung cancer in patients with bronchial artery infusion of cisplatin plasma concentration monitoring of target organs and surrounding tissue concentration-time curve was analyzed. The results showed that during the process of bronchial artery infusion, the blood concentration of the target organ was significantly higher than that of the surrounding tissue, and the plasma concentration of the target organ significantly exceeded the effective anticancer concentration of cisplatin for the treatment of lung cancer by bronchial artery infusion Provides a reliable theoretical basis, and analyzes the matters needing attention in the perfusion process, which is of great significance for guiding the clinical treatment.
