Men's renal function suddenly abnormal abnormalities are actually caused by contrast agents

The Yangtze River Daily Da Wuhan client August 25th news went to the hospital to review the heart, but unexpectedly found that the kidney function was abnormal. The doctor chased the "fierce" layer by layer. The culprit was the culprit "the disaster" during the cardiac surgery. After symptomatic treatment, Mr. Lin's kidney function was recovered and was discharged from hospital on the 25th. Luo Jinhui, director of the Department of Nephrology of Hankou Hospital in Wuhan City, said that acute kidney damage caused by contrast agents is not uncommon in clinic, and it is necessary to attract enough attention to doctors and patients.

A week ago, Mr. Lin, 63, went to Hankou Hospital to review his heart, and found that his kidney function was severely damaged during the examination. "This is impossible. I checked it half a year ago." Mr. Lin was busy explaining to the doctor. The doctor invited Luo Jinhui, the director of the Nephry Medicine. He asked in detail about the medical history that Mr. Lin had not taken nephrotoxic drugs recently, but only undergone cardiac radio frequency ablation surgery 3 days ago. "It is likely to be caused by the combo of the cardiac surgery examination!" After a series of examinations, Luo Jinhui's inference was confirmed that Mr. Lin was diagnosed with a radon aid kidney disease.

"Coper renal disease refers to acute kidney damage that occurs within 72 hours after using iodine." Luo Jinhui introduced that with the widely used clinical application of imaging examination and vascular intervention technology, the current contrast kidney injury has become a low irrigation. The third major cause of medical derivative acute renal damage after sexual acute kidney injury and pharmaceutical acute kidney damage. Data show that about 11%of renal failure is caused by the renal disease of the contrast agent.

He pointed out that iodine -made agents mainly affect the distribution of kidney blood flow, which causes acute damage to renal ischemia and epithelial cells of the renal tubular. Almost all patients with "beating" contrast agents will have a reduction in renal function, but whether acute renal damage occurs depends on whether it has relevant basic diseases.

"If there are high-risk factors, the incidence of contrast kidney disease can reach 20%-50%." Luo Jinhui explained that high-risk factors include renal insufficiency, diabetes, age (> 75 years old) Be careful when receiving a contrast agent. In addition, the use of renal toxic drugs and large doses of contrast agents will also double the risk.

Luo Jinhui pointed out that the kidney disease of the contrast agent is preventing, and the doctor should reasonably evaluate the use of indications for the use of the filmmaking agent and correct the risk factors as much as possible before use. High -risk patients can choose to reduce the incidence of renal diseases in the renal disease in such as an ore -type contrast agent, and minimize the use of contrast agents within the allowable range. The following methods can play a certain role in preventing the kidney disease: stop taking kidney toxic drugs, such as diuretics, diuretic hypoglycemic drugs, antipyretic analgesic drugs, amino glycoside drugs, hemosfen and cyclopylin, etc. ; Drink more water before and after the film inspection. Patients with serious basic renal function and must use contrast agents must be used for dialysis to help the filmmaking agent excrete postoperative postoperative surgery.

Luo Jinhui reminded the public that the urine volume should be closely paid closely within 72 hours after receiving the inspection of the filmmaking agent. People with the above basic diseases should pay special attention. Once the urine output is reduced or urine without urine, they should seek medical treatment immediately.
