Ultrasound investigation in an estimation of renal arteries blood flow dynamic parameters changes in loading testing by nitroglycerine in patients with bronchial asthma
The present research is aimed at dynamic ultrasound evaluation of renal hemodynamic changes in patients suffering from bronchial asthma as the reaction to nitroglycerine functional loading testing. Fift y seven patients having verified diagnosis of medium and heavy bronchial asthma and twenty practically healthy individuals were examined. Th e indicators of background blood fl ow and their dynamic changes were analyzed 3 minutes aft er taking 0,5 mg tablet of nitroglycerine. For ultrasound examination of renal vessels Aloka-5000 (made in Japan) was used. We found out progressive renal blood flow disorders namely blood fl ow decreasing and peripheral resistance in arc and interlobar arteries indices increasing. During nitroglycerine loading testing both healthy individuals and patients having bronchial asthma demonstrated reciprocal dilatory reaction accompanied by statistically valid decrease of blood fl ow and interlobar arteries peripheral resistance indices.
