Symptoms of acute kidney injury?

summary

Acute renal failure, also known as acute renal failure or acute kidney injury, occurs when the kidney cannot filter waste from the blood. Kidneys are important organs in the body, because they support the body to eliminate waste, filter blood, balance body fluids, excrete urine, and other important body functions. Symptoms of acute kidney injury? Next, I'd like to share my views with you.

Symptoms of acute kidney injury?

Reduction of urine volume: oliguria (urine volume < 400ml / D) or anuria (urine volume < 100ml / D) usually occurs several hours or days after onset. Anuria usually indicates complete urinary tract obstruction, but it can also be seen in severe pre renal or renal acute kidney injury (such as renal artery occlusion, vasculitis). However, in patients with non oliguric acute kidney injury, the urine volume may be normal or even excessive.

Nitrogenemia: when acute kidney injury occurs, the metabolites of protein intake can not be excreted by the kidney and stay in the body, which can produce toxic symptoms * uremia. High catabolism occurs when bun increases more than 8.93 mmol / L (25 mg / dl) every day. Patients with oliguric acute kidney injury usually have high catabolism. In addition, the increase of bun is not always due to high catabolism. The absorption of hematoma and massive gastrointestinal bleeding will aggravate azotemia.

Fluid imbalance: due to the reduction of salt and water discharge, water and sodium retention often result in edema, brain edema, pulmonary edema and heart failure, * hypertension and hyponatremia. A large amount of infusion, especially hypotonic fluid, and unrestricted water intake are also the causes of volume overload and hyponatremia. The patient can show drowsiness, progressive slow response, and even seizures (due to brain edema).
