Will pulling out too much blood paddle make a sound on the body

Excessive plasma extraction may affect physical health, with main risks including insufficient blood volume, electrolyte imbalance, hypoalbuminemia, weakened immunity, and coagulation dysfunction.

1. Insufficient blood volume:

Extracting a large amount of plasma in a short period of time can lead to a sudden decrease in circulating blood volume, which may cause orthostatic hypotension, dizziness, and even shock. Human plasma accounts for about 55% of the total blood volume, and a single donation usually does not exceed 600 milliliters, but frequent or excessive extraction can disrupt fluid balance. After donating blood, it is recommended to immediately supplement with 500 milliliters or more of electrolyte drinks and avoid vigorous exercise within 24 hours.

2. Electrolyte imbalance:

Plasma contains important electrolytes such as sodium, potassium, and calcium, and excessive extraction may cause muscle spasms, arrhythmia, and other abnormalities. Especially the loss of calcium ions can lead to increased excitability of nerves and muscles, resulting in hand and foot convulsions. After donation, one should consume more potassium rich foods such as bananas and oranges, and dairy products can help supplement calcium. 3. Hypoproteinemia: Each 100 milliliters of plasma contains 6-8 grams of protein, including albumin, immunoglobulin, etc. A large amount of loss can cause a decrease in plasma colloid osmotic pressure, leading to tissue edema. The clinical manifestation is eyelid or lower limb edema, and in severe cases, intravenous supplementation of human serum albumin is required. Daily recovery can be assisted by high-quality protein foods such as eggs and fish.

4. Decreased immunity:

Immunoglobulin accounts for 15% -20% of plasma protein, and excessive extraction can temporarily weaken humoral immune function. Repeated colds and delayed wound healing may occur. During the recovery period, it is necessary to ensure sufficient sleep, supplement vitamin C and zinc in moderation, and enhance immune cell activity.

5. Coagulation dysfunction:

Excessive removal of coagulation factors from plasma may prolong clotting time and increase the risk of bleeding. Manifested as gum bleeding, subcutaneous bruising, etc. After donation, one should avoid taking anticoagulant drugs such as aspirin and increase the intake of foods rich in vitamin K, such as animal liver and dark green vegetables. After a single donation of 200-400 milliliters of plasma by a healthy adult, the body can usually complete compensation within 48 hours by synthesizing proteins through the liver and accelerating hematopoiesis through the bone marrow. But there should be at least a 14 day interval between two donations, and the annual total should not exceed 10 liters. Special groups such as pregnant women, anemic patients, and low weight individuals should avoid donating. During the recovery period, it is recommended to drink 2000 milliliters of water daily, along with iron supplements such as lean meat and red dates, and engage in moderate aerobic exercise such as brisk walking to promote blood circulation. If symptoms such as persistent fatigue and palpitations persist for more than 3 days, timely medical attention should be sought to check hemoglobin and serum protein levels.
