What should be paid attention to in acute kidney injury? Reminder: Grasp 3 key time points, treatment will be more effective with less effort

Acute kidney injury refers to a phenomenon in which kidney function declines rapidly in a short period of time. Factors such as infection, urethral obstruction and drugs are the main causes of acute kidney injury.

　　Once acute kidney injury occurs, the patient's glomerular filtration rate rapidly declines . It will lead to acid-base imbalance, water and electrolyte imbalance in the body , and will cause urinary retention and other phenomena, which will cause a series of abnormal changes in the patient's multiple systems, so it is necessary to take precautions in all aspects.

　　So, what exactly should be paid attention to in patients with acute kidney injury?

　1. Quickly cut off the source of the disease

　　There are many reasons for acute kidney injury. For example, when acute bleeding and severe diarrhea occur, the blood volume in the body will decrease rapidly , which will affect the blood flow in the kidneys, and the filtration rate of the renal tubules will decrease accordingly. Acute kidney injury occurs.

　　In addition, if you suffer from a series of urinary tract diseases, diabetes, hypertension , and damage by drugs and poisons , acute kidney injury will be induced. Therefore, once you get sick, you should cut off the source of the disease as soon as possible to avoid the aggravation of kidney damage to the greatest extent.

　Second, early scientific treatment

　　Once the patient has a sudden decrease in urination, or symptoms such as no urination, nausea, fatigue , etc., a series of examinations should be carried out under the guidance of a doctor. If it is determined to be caused by acute kidney injury, scientific and standardized treatment must be carried out quickly to avoid aggravation of various uncomfortable symptoms and threaten the life safety of patients.

　　Therefore, after the disease, patients must receive appropriate treatment as soon as possible to reverse the kidney damage to the greatest extent. Especially in the three critical times after the onset of the disease, the patient must do the corresponding treatment and nursing work.

　　What are the three key times that patients with acute kidney injury should seize ?

　1. The initial period

　　The initial period generally refers to within 48 hours after the disease, when patients usually have bleeding or infection problems, but there is no renal parenchymal damage .

　　Some symptoms of the patient's discomfort at this time are relatively mild, but there will be sudden physical weakness , decreased urine output , or red urine . If it can be treated early at this time, it can be cured quickly , and it will hardly cause any damage to the kidneys and body.

　2. Progress

　　The advanced stage mainly includes the oliguric stage, the transition stage and the polyuria stage . The oliguric stage generally lasts for about 7 to 14 days . At this time, the glomerular filtration rate is very low, and it is very likely to cause problems such as hyperphosphatemia, hypocalcemia, metabolic acidosis, or hyperkalemia . At this time, the patient will have very obvious symptoms of hematuria, edema, nausea , or vomiting, and itchy skin .

　　Then patients should be hospitalized to receive corresponding drugs and other methods for treatment, and renal function and fluid balance should be monitored at any time . Once it enters the transitional phase, the patient's renal function begins to gradually improve .

　　When entering the polyuria period, it means that the glomerular filtration rate has begun to return to normal . Once in this stage, patients still need to receive later treatment to prevent recurrence of the disease.

　　3. Recovery period

　　The complete recovery of kidney function generally takes about 6 months to a year , and this period is called the recovery period. At this time, the patient will still have some renal structural and functional defects , so it is still necessary to receive post-treatment and do a good job in life care .

　　All in all, for patients with acute kidney injury, the source of the disease must be cut off quickly once they become ill, and scientific and standardized treatment should be given . And throughout the treatment and recovery period, the above three stages are very important.

　　At each stage , corresponding treatment methods should be taken under the guidance of a doctor, and adjustments in diet, work and rest, exercise, and mentality should be strictly followed by the doctor's instructions . During the recovery period, regular re-examinations should also be carried out . Once abnormality occurs, admission to the hospital for formal treatment is required to maintain their own health to the greatest extent.
