Edema (부기, 부종)

KEYWORDS: ..부종은 조직간액이 비정상적으로 축적되어 있는 상태를 말하며, 흔히 신체 중 dependent part인 legs에 호발한다. 1. Onset? Measured in hours to days : Acute onset - eg. Celluitis, DVT, Compartment syndrome etc Chronic onset - eg. Systemic process, Medication, Chronic venous insufficiency, Lymphedema 2. Clinical course? Intermittent vs constant 3. Pain? Painful - eg. Cellulitis, Ruptured gastronemius, Ruptured Baker’s cyst, Compartment syndrome, DVT Painless - eg. Systemic causes, Lymphedema 4. Associated systemic Symptoms? Fever and chills - Cellulitis, Lymphangitis, or Venous thrombosis Dyspnea, orthopnea, paroxysmal noctural dyspnea - Cardiac origin Recent streptococcal sore throat, recurrent cystitis, hypertension, changes in ocular fundi, U/A, BUN/Cr and Albumin abnormality - Renal pathogenesis Hepatitis, alcoholism, axillary hair loss, palmar erythema, Icterus, spider telangiectasia, Hepatomegaly, splenomegaly, Ascites, abnormal LFT - Hepatic origin 5. Medications? Antidepressants - Monoamine oxidase inhibitors Anti-hypertensive drugs - βblocker, CCB, Clonidine, Diazoxide, Guanethidine, Hydralazine, Methyldopa, Minoxidil, Reserpine Hormone agent - Corticosteroids, Estrogen, Progesterone, Testosterone NSAIDs Edema Key Questions 6. Endocrine diseases? - Cushing’s syndrome,Thyroid dysfunction (pretibial myxedema) 7. Other conditions? - Pregnancy, Salt overload, Sudden cessation of laxative, Diuretic abuse etc ..전신적 부종은 걸을 수 있는 경우는 하지에, 침상 생활만 하는 경우는 천골부 분에 잘 생긴다. ..The distribution of edema (generalized/localized) is useful in diagnosis. Common causes of generalized edema - 심장질환 Congestive heart failure Constrictive pericarditis Restrictive cardiomyopathy - 간경화 - 신장질환 Renal failure Nephrotic syndrome Common causes of Localized edema - Inflammatory disease - Injury : thermal, immune, infectious, mechanical - Occlusion of localized vein or lymphatic drainage 1. Chest radiograph 2. U/A (including microscopic) 3. Biochemistry profile (LFT, albumin, total protein, BUN/Cr) 7 The Root of ambulatory care Key tests Key treatments Edema Fig 1. Diagnostic approach to edema 1. Removal of underlying disease 2. Restriction of sodium intake : < 500mg/day 3. Diuretics : Weight loss by diuretics should be limited to 1~1.5kg/day ..Diuretics는 단지 미용적인 목적으로 사용해서는 안된다. 이뇨제는 aldosterone의 생성을 자극하며 여성의 주기적 부종을 악화시킬 수 있다. ..Albumin투여는 증상개선의 효과가 일시적이어서 치료로서의 의미는 미약 하다. ..보고자에 따라 이견은 있으나, idiopathic cyclic edema치료에 있어 ACE inhibitors가 때때로 효과적이다. (e.g,Captopril 25~50mg bid-tid) Diuretics 처방예 - 울혈성 심부전 1. Furosemide 40mg 1/2T-1T qd or bid Spironolactone 25mg 1/2T-1T qd Edema Localized edema? Albumin < 2.5g/dL Heart failure Renal failure Severe malnutrition Cirrhosis Nephrotic syndrome Azotemia Active urine sediment Increased JVD (jugular venous distension) Decreased CO (cardiac output) Consider : Drug-induced : Steroids, Estrogens, Vasodilators, Hypothyroidism Inflammatory disease/Local Injury (thermal, lmmune, infectious, mechanical) Occlusion of localized vein or lymphatic drainage No No No No Yes Yes Yes Yes 9 The Root of ambulatory care Diuretics 처방예 - 신증후군 1. Furosemide 40mg 1/2T-1T & Spironolactone 25mg 1/2T-1T qd or bid (정상신 기능시) 2. Furosemide 40mg 1T-2T qd or bid (신부전시) Diuretics 처방예 - 간경변 1. Spironolactione 25mg 1/2T-1T bid or tid Overdiuresis may result in hyponatremia, hypokalemia, and alkalosis, which may worsen hepatic encephalopathy. Common ▶ Volume depletion ▶ Prerenal azotemia ▶ Potassium depletion ▶ Hyponatremia-thiazide ▶ Metabolic alkalosis ▶ Hypercholesterolemia ▶ Hyperglycemia-thiazides ▶ Hyperkalemia-K＋ sparing ▶ Hypomagnesemia ▶ Hyperuricemia ▶ Hypercalcemia-thiazides ▶ GI complaints ▶ Rash-thiazides Uncommon ▶ Interstitial nephritis-thiazides, furosemide ▶ Pancreatitis-thiazides ▶ Loss of hearing-loop diuretics ▶ Anemia,leukopenia, thrombocytopeniathiazides 참고 문헌 Ralph Weber : Leg edema,in Saunders Manual of Medical Practice, 2nd ed, Robert E.
