Electrical burns are a result of contact with an electric current, which can cause tissue injury and, in some cases, severe or fatal injury known as electrocution. While electrical injuries are a relatively uncommon cause of burns, they result in a significant number of deaths each year. Electrical burns can lead to hyperkalemia, a condition characterized by high levels of potassium in the blood, which has been linked to metabolic acidosis, red blood cell destruction, rhabdomyolysis, and renal failure. Metabolic acidosis occurs when there is an excessive acid production in the body or when the kidneys fail to adequately remove acid. This condition can be dangerous and even life-threatening if left untreated, and its treatment focuses on addressing the underlying health issue.

Electrical burns can cause hyperkalemia, which includes metabolic acidosis
Electrical burns are a relatively uncommon cause of burns, but they still result in a significant number of deaths each year in the US. They are caused by contact with an electric current, such as live wires or lightning. Electrical injuries can cause hyperkalemia, which has been regarded as a complication in patients with electrical burns.
Hyperkalemia is caused by the destruction of red blood cells, rhabdomyolysis, and the development of renal failure. Rhabdomyolysis is the breakdown of skeletal muscle and the release of their contents into the bloodstream. This can lead to pigment nephropathy, which is damage to the kidneys caused by the presence of myoglobin in the urine. Myoglobin is a protein that is released from damaged muscle cells.
Metabolic acidosis is a type of acidosis that develops when too much acid is produced in the body or when the kidneys cannot remove enough acid from the body. It can be caused by diabetic ketoacidosis, hyperchloremic acidosis, kidney disease, lactic acidosis, poisoning, severe dehydration, and electrical burns. In the case of electrical burns, metabolic acidosis can occur as a result of the destruction of red blood cells and the development of renal failure.
The treatment of metabolic acidosis aims to address the underlying health problem causing it. Sodium bicarbonate may be given to reduce the acidity of the blood, and fluids are often administered intravenously. It is important to seek medical help if one experiences any symptoms of diseases that can cause metabolic acidosis.
In summary, electrical burns can cause hyperkalemia, which includes metabolic acidosis as one of its etiologies. The destruction of red blood cells and the development of renal failure contribute to the occurrence of metabolic acidosis in patients with electrical burn injuries.

Metabolic acidosis can be caused by the destruction of red blood cells
Electrical burns can cause hyperkalemia, which is a condition characterised by high levels of potassium in the blood. Hyperkalemia is associated with metabolic acidosis, which is a disruption of the acid-base balance in the blood. Specifically, metabolic acidosis occurs when there is a buildup of acids in the body, leading to an excess of acids in the blood that wipes out bicarbonate.
Additionally, the destruction of red blood cells can lead to a condition called intravascular hemolysis, where the hemoglobin released from the red blood cells breaks down into bilirubin and iron. This process consumes large amounts of glucose and produces large amounts of lactic acid, which can further contribute to metabolic acidosis.
Moreover, the destruction of red blood cells can be indicative of underlying conditions or complications, such as rhabdomyolysis, which is the breakdown of skeletal muscle, or renal failure, which is the failure of the kidneys. Both of these conditions can contribute to metabolic acidosis. Rhabdomyolysis can lead to pigment nephropathy, which affects kidney function, and renal failure directly impairs the kidneys' ability to regulate acid-base balance, leading to a buildup of acids in the blood.

Rhabdomyolysis and renal failure can also cause metabolic acidosis
Electrical burns are a prevalent problem in some parts of the world, causing a significant number of deaths. Patients with electrical burns often experience hyperkalemia, which is a result of extensive superficial tissue destruction, erythrocyte destruction, and metabolic acidosis.
Metabolic acidosis is a serious condition that can occur due to various factors, including rhabdomyolysis and renal failure. Rhabdomyolysis is a rare muscle injury that causes muscle deterioration and breakdown. This condition can be caused by certain medical conditions, such as genetic diseases like McArdle disease and Duchenne muscular dystrophy, or excessive exercise without rest. It can also be triggered by extended periods of inactivity, particularly in individuals over 65 years of age.
Rhabdomyolysis leads to the release of muscle components, such as creatine kinase (CK), into the bloodstream. These components are normally removed by the kidneys and excreted in the urine. However, in large quantities, these muscle components can damage the kidneys and lead to renal failure. This damage to the kidneys can result in their inability to effectively remove waste products from the body, causing kidney failure, which is life-threatening.
The presence of hyperkalemia in patients with electrical burns is often independent of the severity of rhabdomyolysis or the extent of the burn. However, it is important to note that electrical injuries can result in significant skin and muscle injuries, and the development of hyperkalemia may be influenced by various factors.

Electrical burns can cause hyperkalemia, which can increase the risk of fatal arrhythmias
Electrical burns are a prevalent problem in Colombia, South America, and account for most burn injury deaths. Electrical injuries account for 3–4% of all admissions to burn units in the developed world. Electrical burns are associated with hyperkalemia, which has been regarded as a complication in patients with burn injuries. Hyperkalemia is a common electrolyte disorder in hospitalised adult patients.
Hyperkalemia is characterised by high levels of potassium in the blood. Normally, the blood potassium level is tightly regulated by multiple complex and extensive mechanisms. However, in the context of electrical burns, several factors can contribute to the development of hyperkalemia. These factors include metabolic acidosis, destruction of red blood cells (erythrocytes), rhabdomyolysis, and the development of renal failure or acute kidney injury.
Rhabdomyolysis, a condition characterised by the breakdown of skeletal muscle, can lead to increased potassium levels in electrical injuries. This is because the destruction of muscle cells releases their contents, including potassium, into the bloodstream. Additionally, underlying myopathy or muscle metabolic defects can also contribute to hyperkalemia in some cases of electrical burns.
The presence of hyperkalemia in electrical burn patients is not necessarily correlated with the severity of rhabdomyolysis or the extent of the burn. However, the combination of electrical burns and significant skin and muscle injury is rare in patients exhibiting hyperkalemia. This may be due to the relatively low prevalence of hyperkalemia in electrical burn patients, which was found to be only 1.2% in one study.
The clinical relevance of hyperkalemia in electrical burns stems from its potential to increase the risk of fatal arrhythmias and cause other cardiac complications. Hyperkalemia can lead to abnormal heart and skeletal muscle function, including muscle paralysis. It can also result in respiratory paralysis or cardiac arrest, with levels exceeding 8.5 mEq/L being particularly dangerous. The prognosis for patients with transient hyperkalemia is generally favourable, as full resolution can be expected with the correction of the underlying cause. However, the mortality rate can be as high as 67% if severe hyperkalemia is not treated promptly.

Metabolic acidosis can be treated with sodium bicarbonate to reduce blood acidity
Metabolic acidosis is a condition in which acids build up in the body. This can occur due to untreated diabetes, the loss of bicarbonate in the body, or kidney conditions. Symptoms include an accelerated heartbeat, confusion, and fatigue.
Electrical burns are a common cause of metabolic acidosis. Hyperkalemia, or high potassium levels in the blood, is often observed in patients with electrical burns and is regarded as a complication of such injuries. This condition can lead to metabolic acidosis, along with the destruction of red blood cells, rhabdomyolysis, and renal failure.
While sodium bicarbonate can be beneficial, it is important to note that clinical trials and studies are still ongoing to fully understand its effectiveness and optimal usage. The STARRT-AKI trial, including patients from 15 countries, investigated the use of sodium bicarbonate in patients with stage 2 or 3 acute kidney injury (AKI) and severe metabolic acidosis. The results suggested that these patients may benefit from sodium bicarbonate administration if severe metabolic acidosis persists despite appropriate treatment for underlying conditions.
Additionally, an international observational study found that 18% of patients with moderate to severe metabolic acidosis received sodium bicarbonate in current clinical practice. However, the total amount of sodium bicarbonate administered during the first 24 hours was not adjusted for body weight or base excess. Further research is needed to optimize treatment protocols.
