高强度聚焦超声肿瘤治疗系统的安全应饪

目的探讨高强度聚焦超声肿瘤治疗系统（highintensityfocusedultrasound，HIFU）的安全应用。方法使用HIFUNIT9000超声聚焦治疗仪，治疗患者77例，男40例，女37例；平均年龄53．58；77例中，共计治疗417人次，人均治疗5．42次；观察HIFU治疗期间所出现的明显不良反应。结果77例病人中，有2例治疗后皮肤灼伤；1例因癌性疼痛，不能较长时间水平仰卧，治疗14＂层面后终止治疗；l例治疗后诱发急性胰腺炎。1例治疗中出现心率和血压异常，心率≥120次／rain，收缩压≥180mrnHg，暂停治疗。结论HIFU是一种无创性肿瘤治疗方法，治疗时掌握好适应症、禁忌症、注意事项等，对减少不良反应的发生、提高治疗效果、延长生存期有重要帮助。

The Security Application of High Intensity Focused Ultrasound in the Treatment of Tumor

Objective To discuss the security application of high intensity focused ultrasound （HIFU） in the treatment of tumor. Methods With the use of HIFUNIT9000; the total number of the patients are 77 with male 40 and female 37; the average age is 53.58s 43, among the 77 cases, the total number of treatment is 417, the average number of treatment per person is 5.42; to observe the overt adverse reactions during the HIFU treatment. Results Among the 77 cases, 2 cases appeared skin burn after the treatment; t case ended the treatment after one layer had finished its treatment due to the patient＇ s cancer pain which caused the patient unable lying on the back for long; 1 case induced acute pancreatitis after the treatment. 1 case occurred abnormal heart rate and blood pressure, heart rate 〉I 120 beats/min, systolic blood pressure（SBP） 〉I 180mmHg, stop the treatment. Conclusion HIFU is a non-invasive approach to tumor treatment, to well understand the indications, contradictions and matters needing attention, etc. will help to reduce the adverse reactions, improve the treatment and prolong the survival.
