Whether or not 300 μmol/L creatinine is dangerous depends mainly on the cause and the effect of treatment. If acute kidney injury causes creatinine elevation, after correcting reversible factors, creatinine may return to normal, at this time is usually not dangerous; if chronic renal insufficiency causes creatinine elevation, there may be serious complications such as hyperkalemia, acute left heart failure, at this time is more dangerous.
1. Acute kidney injury: If acute kidney injury is caused by pre-renal factors such as insufficient volume, renal artery stenosis, or post-renal factors such as urethral obstruction, creatinine will be elevated, and creatinine level can be gradually decreased after active treatment and correction of reversible factors, which is usually not dangerous at this time.
2. Chronic renal insufficiency: if chronic renal insufficiency is caused by organic damage of glomerulus itself, the damage of kidney is usually irreversible. When creatinine 300μmol/L may appear hyperkalemia, acute left heart failure and other complications, if the treatment is not timely or the treatment effect is not good, it may be life-threatening, and it is more dangerous at this time.
If patients find that the blood creatinine is elevated, it is recommended to go to regular hospitals in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or treatment under the guidance of the doctor.
