Essentially, skeletal muscle is destroyed (for various reasons) and their intracellular contents (in particular myoglobin) leak into the bloodstream. The kidneys can’t handle this large amount of myoglobin and it can damage them, and in some cases (roughly 30-40% of patients with this develop acute renal failure) can cause kidney failure.
Quite a few things can cause this. One that has been discussed more frequently recently is due to the increase in people engaging in high-intensity workouts (like CrossFit). This causes intense muscle breakdown, which can result in this condition. Trauma can also be a cause, as well as conditions of genetic origin, seizures, metabolic issues, temp-regulating issues, and many medications. A few medications that can cause this to occur include statins, diuretics, aspirin overdose (salicylate toxicity), recreational drugs like cocaine and amphetamines, and narcotics.

Nursing Interventions and Rationales
Ensure fluid resuscitation
- “Expansion of extracellular volume is the cornerstone of treatment and must be initiated as soon as possible.” (Source)
- The amount of urine output, or lack thereof, may dictate various treatment regimens. Patients may need dialysis if oliguria is present.
Insert Foley and prevent infection
- Enables nurse to closely and accurately monitor urine output, foley is a source of infection and must be cared for diligently
- Labs can and will dictate treatment regimens, especially because symptoms can vary widely. CK, serum and urine pH, bicarb, and electrolytes to name a few
Correct electrolytes per orders
- Electrolyte imbalances are common (K, Ca, P are of particular importance)
Monitor for compartment syndrome
- If significant muscle injury occurred, compartment syndrome is a risk. Muscle injury is typical due to decreased perfusion.
Discharge education r/t diet, activity level/prevention
- Diet changes can prevent this in the future when there is a metabolic cause, patients who are active athletes need to ensure they are hydrated appropriately and use caution with intense exercise, and note if they’re experiencing heat stroke. If a medication was noted to cause this, it and alternatives should be evaluated with the prescriber. Prevention is key!
Cornell Note-Taking System Instructions:
- Record: During the lecture, use the note-taking column to record the lecture using telegraphic sentences.
- Questions: As soon after class as possible, formulate questions based onthe notes in the right-hand column. Writing questions helps to clarifymeanings, reveal relationships, establish continuity, and strengthenmemory. Also, the writing of questions sets up a perfect stage for exam-studying later.
- Recite: Cover the note-taking column with a sheet of paper. Then, looking at the questions or cue-words in the question and cue column only, say aloud, in your own words, the answers to the questions, facts, or ideas indicated by the cue-words.
- Reflect: Reflect on the material by asking yourself questions, for example: “What’s the significance of these facts? What principle are they based on? How can I apply them? How do they fit in with what I already know? What’s beyond them?
- Review: Spend at least ten minutes every week reviewing all your previous notes. If you do, you’ll retain a great deal for current use, as well as, for the exam.
