Introduction
Glucose plays several important roles in patients, including rapid energy replenishment, correction of hypoglycemia, provision of metabolic substrates, maintenance of fluid balance, and facilitation of intravenous drug administration. It is a commonly used basic nutritional support agent in clinical practice and should be applied appropriately according to the patient's condition. If a patient has diabetes, hyperglycemia, or experiences adverse reactions after use, prompt medical evaluation is recommended.
Glucose plays several important roles in patients, including rapid energy replenishment, correction of hypoglycemia, provision of metabolic substrates, maintenance of fluid balance, and assistance in drug administration. It is a commonly used foundational nutritional support agent in clinical practice and should be used appropriately according to the patient's condition. If a patient has diabetes, hyperglycemia, or experiences discomfort after use, medical evaluation should be sought promptly.
1. Rapid energy replenishment: Glucose can be directly absorbed and utilized by the body, providing quick energy supply. It is suitable for patients who are fasting, weak, postoperative, or suffering from wasting diseases, helping to relieve symptoms of energy deficiency such as fatigue and dizziness.
2. Correction of hypoglycemia: Timely glucose supplementation rapidly raises blood glucose levels in patients with hypoglycemia, alleviating dangerous symptoms such as palpitations, sweating, and confusion. It is a key method in the emergency treatment of hypoglycemia.
3. Provision of metabolic substrates: Glucose participates in protein and fat metabolism in the body, providing raw materials for tissue repair and immune cell synthesis, thereby supporting recovery after surgery or maintaining basic metabolism in patients with chronic diseases.
4. Maintenance of fluid balance: Glucose solutions can serve as vehicles for fluid replacement, supplementing water while maintaining osmotic pressure. They are suitable for patients with dehydration or electrolyte imbalances, helping to regulate the body's water and electrolyte equilibrium.
5. Assistance in drug administration: Many medications must be dissolved in glucose solution for intravenous infusion. This not only stabilizes the drug properties but also reduces vascular irritation, enhancing both safety and tolerability of drug therapy.
When using glucose, infusion rate and dosage must be strictly controlled to avoid excessive administration that may lead to hyperglycemia. Diabetic patients should use glucose under regular blood glucose monitoring, and their diet should include adequate protein and vitamins to ensure balanced nutrition.
