【摘要】 [目的]观察肾综合征出血热(HFRS)病程中肾血流动力学变化,对HFRS临床各期各型早发现、早诊断、早治疗。[方法]应用彩色多普勒超声诊断仪检测171例经血清学证实的HFRS患者病程中肾各级动﹑静脉血流频谱参数与100例正常人对照。[结果]HFRS肾动脉血流频谱在发热期﹑恢复期与正常对照组比较差异无统计学意义(P﹥0.05),少尿期﹑移行期各级肾动脉RI﹑PI明显高于正常组(P﹤0.01),Vmax﹑Vmin在少尿期最低,尤以Vmin降低显著。[结论]HFRS临床各期肾血流动力学变化存在客观规律,对临床实施治疗方案有指导意义,应用价值较高。更多还原

【Abstract】 [Objective] To observe the hemodynamic changes of kidney arteries in course of Hemorrhagic Fever with Re-nal Syndrome(HFRS),and perform early detection,diagnosis and treatment of different clinical types of HFRS.[Methods] 171 cases with serum-proven HFRS and 100 health people were collected,and their blood flow spectrum parameters of the kid-ney arteries were detected with Color Doppler and compared with controls.[Results] The blood flow spectrum parameters of the kidney arteries among patients with HFRS during the hot stage and convalescence stage did not showed significant difference when compared with the controls(P﹥0.05).The resistant indexes(RI)and pulse indexes(PI)of the kidney arteries during the oliguria stage and migratory stage were significantly higher than those of controls(P﹤0.05).The Vmax and Vmin showed to be the lowest during the oligourinary stage,especially Vmin significantly decreased.[Conclusion] Objective rules exist in the change of kidney hemodynamics of different stage of HFRS,which has great practical values in treatment of HFRS.更多还原
