1. Rhabdomyolysis

횡문근융해증(rhabdomyolysis)은 골격근 섬유의 빠른 파괴 이후 근육세포에서 나오는 잠재적 독성물질이 전신으로 순환하게 되면서 나타나는 전신적인 내과적 상황을 의미한다. 보통 근육 손상 이후 혈청 크레아틴 활성효소(creatine kinase, CK)가 정상 상한치의 10배 이상 상승을 보인 후 정상 수준으로 빠르게 감소하여 유지하는 양상을 보이게 된다. 또한, 횡문근융해증은 근육의 파괴로 인하여 나오는 여러 물질 중 미오글로빈이 소변에 다량 나오면서 어두운 차 또는 콜라색 소변을 동반할 수 있다.
2. 병태생리 및 원인

정상적인 근육세포막의 이온펌프와 채널은 근육 세포내의 나트륨, 칼슘 이온의 농도는 낮게, 칼륨 농도는 높게 유지한다. 근세포막이 직접적인 손상을 입거나, 혹은 여러 가지 다양한 원인으로 에너지 생산이 되지 않는 것이 횡문근융해증의 시작점이다. 막이 파괴되거나 세포내 에너지가 부족해지면, 세포내외의 이온의 농도유지가 되지 않고, 그 중 칼슘이온의 세포 내 농도가 증가하게 된다. 세포 내 칼슘이온이 증가하게 되면, 근육을 과흥분시키고, 미토콘드리아의 기능을 떨어뜨리면서 에너지를 더 고갈시키게 되고, 활성산소가 증가하면서 핵산, 세포 내 지질, 단백질의 과산소화를 유도하고, 다양한 단백분해효소, 인지질 분해효소들을 활성화시켜 횡문근을 융해시킨다.
3. 임상증상

횡문근융해증의 전형적인 임상양상은 급성 혹은 아급성으로 발생되는 근육통, 일시적인 근위부의 근력약화, 콜라색 소변(미오글로빈의 과량함유)이다. 간혹 고열, 구역질, 구토, 의식혼란, 섬망 등이 나타날 수 있다. 횡문근융해증이 생기면서 동반되는 고칼륨혈증은 심부정맥을 유발할 수 있고, 심하면 심정지도 일으킬 수 있으며, 혈청 내의 과량의 인산은 저칼슘혈증을 일으켜 심부정맥을 유발할 수 있다. 가장 중요한 합병증은 급성 신부전으로 횡문근융해증 환자의 14-46%정도에서 나타난다고 보고된다.
4. 진단검사

횡문근융해증에서 근육 손상의 가장 민감한 효소 표지자로 임상 양상이 명확하지 않은 환자에서 초기 진단에 많은 도움이 되는 것은 Creatine Kinase (CK, CPK)이다. 미오글로빈은 단백질의 일종으로 근손상시 분비되며, 소변으로 분비 시 적색뇨나 갈색뇨를 일으킨다. 그 외에 LDH, AST, ALT, 알돌라아제 등의 효소들도 측정하여 근육 손상 정도를 확인한다.
5. 합병증

횡문근융해증의 가장 중요한 합병증은 급성 신부전이다. 급성신부전 환자의 5-10%가 횡문근 융해증에 기인하며, 횡문근 융해증 환자의 25-30%에서 신부전이 발병할 수 있다. 저체액으로 인한 소변량 감소, 요로폐쇄 등이 유발원인으로 보고되고 있다. 대체로 다른 원인에 의하여 발병한 급성 신부전과 비슷한 임상경과를 나타내지만, 횡문근 융해증에 의한 경우에는 특징적으로 요산 및 음이온 차이가 상대적으로 높게 측정된다.
6. 치료 및 간호

치료 방법은 증상의 심한 정도, 동반 질환, 동반손상, 탈수 정도 등 원인에 기초하여 CK 수치, 뇨의 양, 체액 상태를 세밀하게 관찰하면서 신부전증을 예방하고, 혈청내 전해질과 산염기 상태에 따라 수액을 지속적으로 투여해 미오글로빈을 소변으로 배출시켜야한다. 합병증으로 인한 구획증후근(compartment syndrome)이 발생되면 근막절개술(fasciotomy)및 상처관리가 필요하다.
7. 일반혈액검사

일반혈액검사 항목으로는 WBC, Hb, Hct, PLT, ESR, 백혈구 감별계산 등이 있으며, 이를 통해 감염, 빈혈, 염증 등의 상태를 확인할 수 있다.
8. 혈청화학검사

혈청화학검사 항목으로는 BUN, Creatinine, Albumin, T.bilirubin, ALP, AST, ALT 등이 있으며, 이를 통해 신장기능, 간기능, 전해질 상태 등을 확인할 수 있다.
9. 전해질검사

전해질검사 항목으로는 Calcium, Phosphorus, Na, K, Cl 등이 있으며, 이를 통해 전해질 불균형 여부를 확인할 수 있다.
10. 기타검사

기타 검사로는 PT, aPTT, CK, CK-MB, Troponin I 등의 심장효소검사와 소변검사 등이 있다.

1. Rhabdomyolysis

Rhabdomyolysis is a serious and potentially life-threatening condition that occurs when damaged skeletal muscle tissue releases its contents, including myoglobin, into the bloodstream. This can lead to various complications, including acute kidney injury, electrolyte imbalances, and even multi-organ failure if left untreated. Understanding the pathophysiology, clinical presentation, diagnostic workup, and management of rhabdomyolysis is crucial for healthcare professionals to provide timely and effective care for patients. Early recognition of the condition, prompt initiation of treatment, and close monitoring of the patient's condition are essential to prevent or mitigate the development of severe complications and improve patient outcomes.
2. 병태생리 및 원인

Rhabdomyolysis can have a variety of underlying causes, including traumatic injury, strenuous exercise, certain medications or toxins, genetic disorders, and various medical conditions. The common pathophysiological mechanism involves the disruption of the skeletal muscle cell membrane, leading to the release of intracellular contents, such as myoglobin, creatine kinase, and electrolytes, into the bloodstream. This can result in systemic effects, including acute kidney injury, electrolyte disturbances, and potentially life-threatening complications. Understanding the specific causes and underlying pathophysiology is crucial for healthcare providers to identify the underlying etiology, implement appropriate preventive measures, and tailor the management approach for each patient.
3. 임상증상

The clinical presentation of rhabdomyolysis can vary widely, ranging from asymptomatic cases to severe, life-threatening conditions. Common symptoms include muscle pain, weakness, and swelling, often accompanied by dark-colored urine (due to the presence of myoglobin). In more severe cases, patients may experience nausea, vomiting, confusion, and even coma. Recognizing the early signs and symptoms of rhabdomyolysis is crucial for healthcare providers to initiate prompt diagnosis and treatment, as delayed recognition can lead to the development of serious complications, such as acute kidney injury, electrolyte disturbances, and cardiovascular instability. Careful assessment of the patient's clinical history, physical examination, and laboratory findings is essential for accurate diagnosis and appropriate management.
4. 진단검사

Diagnosing rhabdomyolysis involves a comprehensive diagnostic workup, including laboratory tests and, in some cases, imaging studies. The key diagnostic tests include serum creatine kinase (CK) levels, which are typically elevated in rhabdomyolysis, as well as assessment of renal function, electrolyte levels, and urinalysis. Elevated CK levels, often more than five times the upper limit of normal, are a hallmark of rhabdomyolysis and can help confirm the diagnosis. Additionally, evaluating the patient's clinical presentation, medical history, and potential triggering factors can aid in the diagnostic process. In some cases, imaging studies, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans, may be used to assess the extent of muscle damage or rule out other underlying conditions. A thorough diagnostic approach is crucial for guiding appropriate treatment and monitoring the patient's progress.
5. 합병증

Rhabdomyolysis can lead to a range of potentially life-threatening complications if not recognized and managed promptly. The most serious complication is acute kidney injury, which can occur due to the direct toxic effects of myoglobin on the kidneys, as well as dehydration and electrolyte imbalances. Other potential complications include electrolyte disturbances (such as hyperkalemia, hypocalcemia, and hyperphosphatemia), compartment syndrome, disseminated intravascular coagulation, and even multi-organ failure. Cardiovascular complications, such as arrhythmias and hypotension, can also occur due to the release of intracellular contents and electrolyte imbalances. Recognizing and managing these complications in a timely manner is crucial to prevent further deterioration and improve patient outcomes. Healthcare providers must closely monitor patients with rhabdomyolysis and be prepared to intervene promptly to mitigate the development of these serious complications.
6. 치료 및 간호

The management of rhabdomyolysis involves a multifaceted approach, focusing on identifying and addressing the underlying cause, preventing or mitigating complications, and providing supportive care. The cornerstone of treatment is aggressive fluid resuscitation, which aims to maintain adequate urine output and prevent the development of acute kidney injury. Intravenous fluid administration, often with the addition of bicarbonate or mannitol, can help dilute and facilitate the excretion of myoglobin. Careful monitoring of the patient's fluid status, electrolyte levels, and renal function is crucial during this process. In severe cases, dialysis may be necessary to manage electrolyte imbalances and support renal function. Additionally, addressing the underlying cause, such as discontinuing offending medications or treating the underlying medical condition, is essential. Nursing care plays a vital role in the management of rhabdomyolysis, including close monitoring of the patient's clinical status, administering medications, and providing supportive care to prevent and manage complications. Effective communication and coordination among the healthcare team are essential for optimizing patient outcomes.
7. 일반혈액검사

General blood tests are an essential component of the diagnostic workup for rhabdomyolysis. These tests provide valuable information about the patient's overall health status and can help identify the underlying cause and monitor the progression of the condition. Key blood tests include a complete blood count (CBC) to assess for anemia, leukocytosis, or other hematological abnormalities; liver function tests to evaluate for hepatic involvement; and coagulation studies to assess for disseminated intravascular coagulation. Additionally, inflammatory markers, such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), may be elevated in cases of rhabdomyolysis. Careful interpretation of these general blood test results, in conjunction with the patient's clinical presentation and other diagnostic findings, can help guide the healthcare team in establishing the diagnosis, identifying the underlying etiology, and monitoring the patient's response to treatment.
8. 혈청화학검사

Serum chemistry tests are crucial in the evaluation and management of rhabdomyolysis. The key serum chemistry tests include: 1. Creatine kinase (CK): Elevated CK levels, often more than five times the upper limit of normal, are a hallmark of rhabdomyolysis and help confirm the diagnosis. 2. Electrolytes (sodium, potassium, chloride, and bicarbonate): Electrolyte imbalances, such as hyperkalemia, hypocalcemia, and hyperphosphatemia, can occur due to the release of intracellular contents and require close monitoring and management. 3. Renal function tests (blood urea nitrogen and creatinine): Assessing renal function is crucial, as acute kidney injury is a common and potentially life-threatening complication of rhabdomyolysis. 4. Liver function tests (aspartate aminotransferase, alanine aminotransferase, and bilirubin): Elevated liver enzymes may indicate hepatic involvement or underlying liver disease. Interpreting these serum chemistry results, in the context of the patient's clinical presentation and other diagnostic findings, helps healthcare providers identify the underlying cause, assess the severity of the condition, and guide appropriate treatment and monitoring strategies. Careful management of electrolyte imbalances and renal function is essential to prevent or mitigate the development of serious complications in patients with rhabdomyolysis.
9. 전해질검사

Electrolyte testing is a critical component of the diagnostic and management approach for patients with rhabdomyolysis. The release of intracellular contents, including electrolytes, can lead to significant imbalances that require close monitoring and prompt intervention. Key electrolyte tests include: 1. Serum potassium (K+): Hyperkalemia is a common and potentially life-threatening complication of rhabdomyolysis, as the released potassium from damaged muscle cells can accumulate in the bloodstream. Careful monitoring and management of hyperkalemia are essential. 2. Serum calcium (Ca2+): Hypocalcemia can occur due to the precipitation of calcium-phosphate complexes, and it may contribute to neuromuscular and cardiac complications. 3. Serum phosphate (PO4): Hyperphosphatemia can result from the release of phosphate from damaged muscle cells and may lead to further complications, such as hypocalcemia and renal impairment. 4. Serum sodium (Na+) and chloride (Cl-): Disturbances in sodium and chloride levels can occur and may require fluid and electrolyte management. Interpreting the electrolyte panel, in conjunction with the patient's clinical presentation, renal function, and other laboratory findings, is crucial for healthcare providers to identify and address electrolyte imbalances, guide appropriate fluid and electrolyte management, and prevent or mitigate the development of life-threatening complications in patients with rhabdomyolysis.
10. 기타검사

In addition to the general blood tests, serum chemistry, and electrolyte assessments, healthcare providers may order other diagnostic tests to evaluate patients with suspected rhabdomyolysis. These additional tests can provide further insights into the underlying cause, extent of muscle damage, and potential complications. 1. Urinalysis: Examination of the urine can reveal the presence of myoglobin, which appears as a dark, reddish-brown discoloration. Urinalysis can also detect proteinuria, hematuria, and other indicators of renal involvement. 2. Imaging studies: Techniques such as magnetic resonance imaging (MRI) or computed tomography (CT) scans may be used to assess the extent of muscle damage, identify the underlying cause (e.g., compartment syndrome, traumatic injury), or rule out other conditions. 3. Genetic testing: In cases of suspected inherited or genetic disorders associated with rhabdomyolysis, genetic testing may be performed to identify the underlying genetic mutation or predisposition. 4. Muscle biopsy: In rare cases, a muscle biopsy may be considered to confirm the diagnosis, identify the specific cause of muscle damage, or rule out other neuromuscular disorders. The integration of these additional diagnostic tests, along with the patient's clinical history, physical examination, and other laboratory findings, can provide a comprehensive assessment of the patient's condition, guide the identification of the underlying cause, and inform the development of a tailored treatment plan to optimize patient outcomes.
