When Rhabdomyolysis Becomes Serious and Requires an ER Visit

Sep 11, 2023

Rhabdomyolysis is distinguished by the breakdown of muscle fibers, which release harmful substances into the bloodstream. It can result in severe complications if not promptly addressed. Recognizing the signs and symptoms of rhabdomyolysis and understanding when it becomes serious is crucial for seeking immediate medical attention. Let’s explore rhabdomyolysis, its causes, symptoms, when it becomes serious, and how the emergency room (ER) can assist in its treatment.

What is Rhabdomyolysis?

Rhabdomyolysis is a condition where muscle fibers break down, releasing substances such as myoglobin, creatine kinase, and potassium into the bloodstream. These substances can be toxic to the body and potentially cause harm to various organs, particularly the kidneys. Physical trauma, intense exercise, certain medications, infections, metabolic disorders, and drug abuse can cause rhabdomyolysis.

Causes and Symptoms of Rhabdomyolysis:

Rhabdomyolysis can be triggered by several factors, including:

  1. Physical Trauma: Severe injuries, crush injuries, or muscle damage due to accidents or trauma
  2. Intense Exercise: Extreme or prolonged physical exertion, especially when muscles are not accustomed to such activity
  3. Medications and Toxins: Certain medications, like statins, used to lower cholesterol, illicit drug use, or exposure to toxins
  4. Infections: Bacterial or viral infections, including influenza, sepsis, or muscle infections
  5. Metabolic Disorders: Inherited muscle disorders or metabolic conditions affecting muscle function

Symptoms of rhabdomyolysis may include:

  1. Muscle Pain and Weakness: Severe muscle pain, tenderness, stiffness, or weakness
  2. Dark Urine: Urine may appear dark or cola-colored due to the presence of myoglobin
  3. Decreased Urine Output: Reduced urine production or oliguria
  4. Generalized Weakness and Fatigue: Feeling tired, lazy, or experiencing overall weakness
  5. Nausea and Vomiting: Feeling nauseous and vomiting
  6. Abdominal Pain:  Abdominal discomfort or pain
  7. Altered Mental Status: Confusion, delirium, or decreased consciousness
  8. Irregular Heartbeat: Heart palpitations or abnormal heart rhythms

When Rhabdomyolysis Becomes Serious?

Rhabdomyolysis should always be taken seriously due to its potential complications. It becomes particularly serious when:

  1. Severe Muscle Damage: Extensive muscle breakdown releases significant toxins into the bloodstream.
  2. Kidney Involvement: Toxic substances, particularly myoglobin, can cause acute kidney injury or kidney failure.
  3. Electrolyte Imbalances: Rhabdomyolysis can lead to imbalances in electrolyte levels, especially high potassium levels (hyperkalemia), which can affect heart rhythm and potentially lead to cardiac arrhythmias.

How Can ER Help in Rhabdomyolysis Treatment?

Seeking immediate medical attention at the ER near you is crucial when rhabdomyolysis is suspected. The ER staff has the expertise and resources to provide timely diagnosis and treatment. Here’s how the ER can assist:

  1. Diagnosis and Evaluation: The medical team will perform a thorough physical examination, review the patient’s medical history, and conduct diagnostic tests to confirm the diagnosis of rhabdomyolysis. These tests may involve blood tests to assess muscle enzymes (such as creatine kinase), electrolyte levels, kidney function, and urine tests to detect the presence of myoglobin.
  2. Fluid Resuscitation and Electrolyte Management: One of the primary goals of treatment is to flush out the toxic substances from the body and restore fluid and electrolyte balance. Intravenous fluid therapy is initiated to maintain hydration and promote urine production, helping to prevent kidney damage.
  3. Monitoring and Supportive Care: The emergency room staff will closely monitor vital signs, kidney function, electrolyte levels, and urine output. In severe cases, patients may require interventions such as dialysis to support kidney function until they recover.
