Teaching Point: Describe the etiology/pathophysiology, clinical manifestations, assessment, diagnosis, and medical management of varicose veins. Minutes Allocated Time: Introduction: Learner Participation: Knowledge Lesson Please follow along with your hand outs and take notes. Skill Lesson Powerpoint presentation with associated handouts. Learning Support: 1. Varicose veins a. Etiology i. Varicose vein is a tortuous, dilated vein with incompetent valves. ii. Highest incidence is women 40 to 60 years of age. iii. Fifteen percent of the population is affected. iv. The great and small saphenous veins are most often affected. b. Causes i. Congenitally defective valves ii. Incompetent valve iii. Absent valve iv. External pressure on leg from pregnancy v. Poor posture vi. Constrictive clothing vii. Prolonged standing c. Pathophysiology i. The vessel wall weakens and dilates thereby stretching the valves and resulting in pooling in the blood. ii. This leads to varicosities in the veins. d. Clinical manifestations i. Varicosities can be primary or secondary. ii. Primary have a gradual onset and affect superficial veins. iii. Secondary affect the deep veins and result from venous insufficiency and thrombosis. e. Signs and Symptoms i. Signs include darkened veins on the lower extremities. ii. Symptoms include: iii. Fatigue iv. Dull ache v. Cramping of the muscles vi. Feeling of heaviness all arising from a decreased blood flow to the tissues. f. Assessment i. Signs include darkened veins on the lower extremities. ii. Symptoms include: 1. Fatigue 4 AFAMS Master Lesson Plan (MLP) Nursing Program Venous Vascular Disease 2. Dull ache 3. Cramping of the muscles 4. Feeling of heaviness all arising from a decreased blood flow to the tissues. g. Diagnostic test i. Trendelenburg's test is done to diagnose the ability of the valves to support a column of blood by measuring venous filling time 1. Patient lies down with the affected leg elevated for venous emptying 2. A tourniquet is placed above the knee and the patient stands 3. The filling time for the veins are recorded before and after the tourniquet is removed 4. When the veins fill rapidly from backward flow the veins are considered to be incompetent h. Surgical management i. Surgery is comprised of vein ligation and stripping. ii. The great saphenous vein is ligated close to femoral junction and the veins are stripped.

Teaching Point: Describe the etiology/pathophysiology, clinical manifestations, assessment, diagnosis, and medical and nursing management of a venous stasis ulcer. Minutes Allocated Time: Introduction: Learner Participation: Knowledge Lesson Please follow along with your hand outs and take notes. Skill Lesson Powerpoint presentation with associated handouts. Learning Support: 1. Venous stasis ulcer a. Etiology - Stasis ulcer or leg ulcer occur due to chronic deep vein insufficiency and statis of the blood in the venous system. i. Other causes include severe varicose veins, burns, trauma, sickle cell anemia, diabetes, and neurogenic disorders. ii. A leg ulcer is an open, necrotic lesion. b. Pathophysiology i. Necrotic lesions are formed when inadequate supply of oxygen rich blood and nutrients reach the tissues. This results in cell death and tissue sloughing. ii. Decreased circulation to the area leads to the development of infection and increased healing time. c. Assessment i. Subjective 1. Onset and duration of pain and relief factors. 2. Interview patient about all predisposing factors. ii. Objective 1. Check for size and depth of ulceration. 2. Presence of edema. 3. Palpate and compare pedal pulses. iii. Diagnostic tests 1. Doppler ultrasonography. 2. Venography . 3. confirm venous insufficiency and stasis. iv. Medical management 1. Focused on prevention of infection and promotion of wound healing. 6 AFAMS Master Lesson Plan (MLP) Nursing Program Venous Vascular Disease 2. Diet is crucial to ensure proper wound healing. 3. Large amounts of protein are lost in the form of albumin through the ulcers. High intake of protein is essential. 4. Vitamins A, C and the mineral zinc are administered to ensure proper healing. 5. Debridement to remove necrotic tissue is in three forms: a. Mechanical - wet to dry dressing is used to remove debris when the dry dressing is removed. b. Chemical - enzymes are applied to break down necrotic tissue. c. Surgical - is performed using a scalpel when all other measures have failed. 6. Antibiotics 7. Protection of the ulcerated area using the Unna's boot. 8. See figure 8-23 on page 345 for illustration of the application of Unna's boot. 9. The boot is left on for 1-2 weeks but may be changed more frequently based on drainage. v. Nursing interventions 1. Focus on promoting tissue healing . 2. Nursing Diagnosis: a. Skin integrity, impaired, related to open ulceration. i. Interventions: 1. Perform dressing changes. 2. Assess wound for sign of infection. 3. Provide prescribed antibiotic therapy. 4. Provide adequate nutritional support. 5. Collaborate with dietitians. b. Tissue perfusion, ineffective, peripheral, related to insufficient venous circulation. i. Interventions: 1. Elevate extremities to promote venous return. 2. Protect extremity using bed cradle to pressure of the linen. 3. Assess level of pain and provide pain relief measures. 3. Clinical manifestations a. Pain is present from mild to dull ache relieved by elevation. b. Skin is visibly ulcerated most often on the medial aspect of the ankle accompanied by dark pigmentation. c. Edema may be present and pedal pulses may be present. 7 AFAMS Master Lesson Plan (MLP) Nursing Program Venous Vascular Disease Knowledge Lesson: Question: Answer: Check on Learning In a knowledge lesson, pose questions to the class.
