What is sodium lactate Ringer used for?
What is sodium lactate Ringer used for:
① Fluid supplementation during surgery: During surgery, patients often experience fluid loss due to bleeding, tissue fluid leakage, etc. Sodium lactate Ringer can be used to timely supplement extracellular fluid and maintain fluid balance.
. For example, in abdominal surgery, the patient's surgery time is about 2-3 hours, and when the estimated fluid loss is 500-800ml, medical staff will administer sodium lactate Ringer through intravenous infusion, with an infusion rate controlled at 80-120 drops/minute, and adjust the speed according to the actual bleeding situation during the surgery. The concentration of sodium ions, chloride ions, and calcium ions in its composition is similar to that of human plasma, which can be quickly absorbed and utilized by the body, avoiding problems such as low blood pressure and insufficient tissue perfusion caused by insufficient body fluids. After the surgery, 500-1000ml will be continued to be infused based on the patient's urine output, blood pressure, and other indicators to help restore circulating blood volume and promote postoperative physical function recovery.
② First aid for patients with traumatic shock: When a patient experiences severe trauma, such as fractures, extensive burns, etc., causing shock, sodium lactate Ringer is an important emergency fluid replacement option. For example, in patients with extensive burns, when the burn area exceeds 20%, there will be a large amount of fluid leakage, leading to a sharp decrease in effective circulating blood volume and causing shock. At this point, it is necessary to immediately establish a venous access and rapidly administer sodium lactate Ringer. The initial infusion rate can reach 150-200 drops/minute, and 1000-1500ml should be infused within 1-2 hours to rapidly increase blood pressure and improve tissue hypoxia. Meanwhile, the lactate ions it contains can be metabolized into bicarbonate ions in the body, which can correct metabolic acidosis that may accompany traumatic shock and maintain acid-base balance. During the emergency process, the patient's blood pressure, heart rate, blood oxygen saturation, and other indicators will be closely monitored, and the infusion volume and speed will be adjusted based on the monitoring results to buy time for subsequent treatment.
③ Dehydration correction of infectious diseases: sodium lactate ringer can be used to correct dehydration and electrolyte disorders when infectious diseases such as acute gastroenteritis, pneumonia, etc. cause dehydration symptoms such as vomiting, diarrhea, high fever and sweating. Taking patients with acute gastroenteritis as an example, they vomit 3-5 times a day and experience diarrhea 4-6 times, accompanied by dehydration symptoms such as fatigue and dry mouth. Examination shows a mild decrease in blood sodium and potassium levels. Medical staff will administer sodium lactate Ringer intravenous infusion, with the infusion volume depending on the degree of dehydration. Mild dehydration patients will receive 1000-1500ml per day, while moderate dehydration patients will receive 1500-2000ml per day. The infusion rate should be controlled at 60-80 drops per minute. This solution can replenish the lost water and electrolytes of patients, alleviate symptoms such as fatigue and dry mouth, and the metabolism of lactate can help regulate the acid-base imbalance caused by vomiting and diarrhea, promote the recovery of intestinal function in patients, and reduce the damage of dehydration to body organs.
④ Fluid regulation of pregnant women during the perinatal period: During the perinatal period, pregnant women may experience fluid imbalance due to sweating, bleeding, or complications such as preeclampsia. Sodium lactate Ringer can be used to regulate the fluid status of pregnant women. For example, during natural childbirth, continuous uterine contractions in pregnant women can consume a lot of physical energy, accompanied by sweating and possible mild dehydration. At this time, sodium lactate Ringer is infused at a rate of 50-70 drops/minute to supplement water and electrolytes, maintain the pregnant woman's physical strength, and ensure smooth delivery. For pregnant women with severe vomiting during pregnancy, frequent vomiting and inability to eat and drink normally can easily lead to severe dehydration and electrolyte imbalance, and even affect fetal development. Therefore, intravenous infusion of sodium lactate Ringer is necessary, with a daily infusion volume of 1500-2500ml, adjusted according to the pregnant woman's weight, vomiting volume, and electrolyte examination results to correct dehydration and electrolyte imbalance and provide a stable intrauterine environment for the fetus.
⑤ Intensive care patient supportive treatment: In the intensive care unit (ICU), many critically ill patients such as those with multiple organ failure, severe infections, etc. often have complex fluid, electrolyte, and acid-base balance disorders. Sodium lactate Ringer is one of the important supportive treatment drugs. Taking patients with multiple organ failure as an example, due to impaired organ function, they are unable to regulate body fluids and electrolytes normally, which can lead to low blood volume, electrolyte imbalance, and metabolic acidosis. Medical staff will accurately administer sodium lactate Ringer based on the patient's central venous pressure, blood gas analysis, and electrolyte monitoring results, with a daily infusion volume of 2000-3000ml, slowly administered in batches, and the speed adjusted according to the patient's circulatory status to avoid increasing the burden on the heart. By supplementing the solution, the effective circulating blood volume of the patient is maintained, electrolyte imbalance and acid-base imbalance are corrected, favorable conditions are created for the recovery of organ function, and other treatment measures are assisted to improve the success rate of patient treatment.
