Medical & Surgical Conditions

Blood and Lymphatic

Disorders

Blood and Lymphatic Disorders

Laboratory Tests• RBC (erythrocytes) 4-6 million/cu.mm• Hemoglobin 10-20 gm/100ml• Hematocrit 40-50 percent• WBC 5,000-10,000/mm• Platelets 150,000-400,000/mm

Anemia

Definition• Disorder characterized by RBC and

hemoglobin and hematocrit levels below normal range

• Causes delivery of insufficient amounts of oxygen to tissues and cells

Anemia

Types• Blood loss (hemorrhage)

• Impaired production of RBC’s (bone marrow depression)

• Increased destruction of RBC’s (hemolysis)

• Nutritional deficiencies (long term iron deficiency)

Anemia

Signs & Symptoms• Anorexia• Cardiac dilation• Disorientation• Dyspepsia• Dyspnea• Exertional dyspnea• Fatigue• Headache

• Insomnia• Pallor• Palpitation• Shortness of breath• Systolic murmur• Tachycardia• Vertigo

Hypovolemic Anemia

Etiology/Pathophysiology• Abnormally low circulating blood volume due

to blood loss• 500 ml loss can be tolerated• 1000 ml loss can be severe complications• Severity and signs and symptoms depend on

how rapid the blood is lost

Hypovolemic Anemia Signs & Symptoms

• Weakness• Stupor• Irritability• Pale, cool, moist skin• Hypotension• Tachycardia (rapid, weak, thready pulse)

• Hypothermia• Hemoglobin less than 10 gm/100ml• Hematocrit less than 40 %

Treatment• Control bleeding• Treat shock

• O2, elevate lower extremities, keep warm

• Replace fluid• blood transfusion, plasma, dextran, lactaed ringers

• Monitor vital signs

Pernicious Anemia

Etiology/Pathophysiology• Absence of the intrinsic factor• Intrinsic factor is essential for the absorption of

vitamin B12• Deficiency of vitamin B12 affects growth and

maturity of all body cells• RBC’s in the bone marrow don’t mature• RBC membrane ruptures easily
