From the Guidelines
Intravenous calcium gluconate is not a disease, but rather a treatment used to manage conditions such as hyperkalemia, hypocalcemia, and calcium channel blocker overdose. When considering the use of intravenous calcium gluconate, it's essential to understand its role in managing specific medical conditions. For hyperkalemia, which is a condition characterized by elevated potassium levels in the blood, intravenous calcium gluconate can help reduce the risk of cardiac arrhythmias by stabilizing cardiac membranes 1. The typical dose for acute hyperkalemia is not explicitly stated in terms of grams, but it is known that calcium gluconate administration rapidly reduces the membrane excitatory effects of potassium on cardiac tissue within 1 to 3 minutes 1. In cases of suspected hyperkalemia leading to cardiac arrest, guidelines suggest the administration of IV calcium as part of the treatment protocol 1. It's crucial to note that while calcium gluconate can help manage the symptoms of hyperkalemia, it does not reduce total body potassium levels; hence, it is often used in conjunction with other treatments like insulin, glucose, and beta-agonists 1. Monitoring of calcium levels and adjustment of dosing as necessary is vital to avoid complications such as hypercalcemia and cardiac arrhythmias 1. Given the potential for serious side effects and the need for careful management, the use of intravenous calcium gluconate should be guided by the most recent and highest quality clinical evidence available, prioritizing patient outcomes in terms of morbidity, mortality, and quality of life. Key considerations include the specific indication for its use, the appropriate dosing regimen, and the importance of monitoring for potential adverse effects, all of which are informed by the latest clinical guidelines and research findings 1.

From the Research
IV Calcium Gluconate Disease
- IV calcium gluconate is used to treat hypocalcemia, a condition where the serum calcium level is low 3, 4, 5, 6, 7.
- The efficacy of IV calcium gluconate in treating hypocalcemia has been evaluated in several studies, with results showing that it can effectively increase serum calcium levels in patients with mild to severe hypocalcemia 3, 4, 5.
- The dose-dependent characteristics of IV calcium gluconate therapy have been evaluated, with studies showing that higher doses (4g) are more effective in treating moderate to severe hypocalcemia than lower doses (2g) 4, 5.
- IV calcium gluconate is preferred over other calcium salts, such as calcium chloride, due to its lower irritation of the vessel wall and better compatibility with other nutrients in parenteral nutrition 6.
- The treatment of hypocalcemia with IV calcium gluconate requires careful monitoring of serum calcium levels to avoid overcorrection and hypercalcemia 3, 5.
- Hypocalcemia can be caused by various disorders, including hypoparathyroidism and vitamin D metabolism disorders, and treatment options vary depending on the underlying disorder 7.
- IV calcium gluconate is also used to treat other conditions, such as fluoride or oxalic acid poisoning, decreased myocardial contractility, and acute allergic conditions 6.
