captopril renogram test

The captopril kidney test was carried out by the following principle. Captopril is a new type of antihypertensive drug. Its main function is to dilate peripheral blood vessels and reduce peripheral resistance to lower blood pressure. However, lowering blood pressure also reduces renal artery perfusion and reduces glomerular filtration rate. The kidney map with decreased filtration rate is characterized by a decrease in excretion peaks and a delay in excretion. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting Tips: You should pay attention to the normal diet before the examination, pay attention to normal work and rest, and prevent endocrine disorders. Normal value There were no significant differences between the two kidney maps. Clinical significance Renal vascular hypertension test is positive, especially in patients with unilateral renal vascular disease. The bilateral kidney map is more obvious than the above changes. Abnormal results: Renal vascular hypertension due to excessive secretion of renin, angiotensin synthesis after captopril was blocked, blood pressure decreased, renal blood flow decreased more significantly. People who need to be examined: patients with renal vascular hypertension. Precautions Inappropriate population: severe renal impairment. Forbidden before examination: pay attention to normal diet, pay attention to normal work and rest, and prevent endocrine disorders. Requirements for inspection: Keep the seat position unchanged during the process. Inspection process Methods: The routine kidney diagram was performed first, and captopril was administered orally after 25 hours, 25 mg. After taking the drug for 1 hour, do another kidney map and compare the two kidney images. Judgment: The peak of the second kidney map was lower than the first and the delay was positive. Not suitable for the crowd Severe renal impairment. Adverse reactions and risks No related complications or hazards.
