What should we pay attention in renal edema?2018-01-30 16:47
The pathologic process of excessive accumulation of fluid in the interstitial space or in the body cavity is called edema. The edema of the body caused by the dysfunction of the kidney is called renal edema.
Renal edema is characterized by edema occurs first in the loose parts of the organization, such as the eyelids or facial, ankle, to clear the morning, when severe can extend to the lower limbs and the body. The nature of renal edema is soft and easy to move, clinically concave edema, that is, if you press your finger on your skin, you can have a depression.
Renal edema is the most common symptom of kidney disease, light eyelid and facial edema, severe systemic edema or pleural effusion and ascites. The causes of renal edema are generally divided into two categories: First, decreased glomerular filtration, and tubular reabsorption of sodium and sodium is still good, resulting in water-sodium retention, this time often accompanied by increased systemic capillary permeability, the tissue gap In the water retention slip, this situation is more common in nephritis. Another reason is that plasma protein is too low due to a large amount of proteinuria.
We all know that patients with kidney disease should limit salt intake, the specific principle is: patients with severe edema salt intake should be 1.7 to 2.3 grams daily; mild to moderate edema in patients with daily intake of salt 2.3 to 2.8 grams. In addition to low-salt diet, we certainly know that we should also take a low-protein diet, specifically how to intake of high-quality low-protein?
Patients with severe edema and severe hypoproteinemia should take 1 g protein intake per kg body weight per day (eg, 50 kg protein intake per day, 50 g protein intake) with proteinuria; mild or moderate edema in patients with daily weight per kilogram should be intake of 0.5 ~ 0.6g protein, while ensuring heat supply.
In addition to these, patients with edema also need to pay attention to: Many patients with edema, all the time thinking about drinking water ... but limited drinking water in doctor's order. For health, still need scientific drinking water.
We have to learn to calculate the amount of water intake, because the amount of water, and how much the urine is related, so the need to calculate the amount of urine output. The formula is: The patient's daily water intake = the previous day's total urine output +500 ml is appropriate.
This water intake also includes the hidden water content of daily intake of food. For example, fresh fruits and vegetables have a moisture content of 65% to 90%, so when calculating the amount of patient intake to take these hidden water content is also included.
In addition, patients with oliguria or anuria during the terminal stages of the disease should not blindly limit water intake to prevent further deterioration of renal function. Should be treated differently to protect the patient's residual renal function for the purpose.
