Study Notes
- Raynaud's disease affects blood vessels, mainly in fingers and toes
- Exposure to cold or stress causes blood vessels to narrow
- Reduced blood flow from constriction results in numbness, tingling, and color changes
Primary vs. Secondary Raynaud's
- Primary Raynaud's (Raynaud's disease) has no known cause and is typically milder
- Secondary Raynaud's (Raynaud's phenomenon) is caused by conditions like lupus, scleroderma, or rheumatoid arthritis
- Secondary Raynaud's is usually more severe
Signs and Symptoms
- Cold fingers or toes
- Skin color changes in response to cold or stress
- Numbness, tingling, or pain in fingers or toes
- During an attack, skin may turn white, then blue, and finally red as blood flow returns
Triggers
- Exposure to cold temperatures, such as cold weather or handling cold objects
- Emotional stress
- Smoking
- Certain medications e.g. beta-blockers, decongestants
Diagnosis
- Physical exam to observe color changes in fingers or toes
- Medical history review
- Nailfold capillaroscopy to examine small blood vessels at the base of the fingernail
- Blood tests to check for underlying conditions associated with secondary Raynaud's
Treatment
- Focuses on managing symptoms and preventing attacks
- Lifestyle modifications, such as avoiding cold temperatures, wearing warm clothing, and managing stress
- Medications, such as calcium channel blockers or vasodilators, to improve blood flow
Nursing Interventions and Education
- Instruct the client to avoid exposure to cold
- Advise the client to wear gloves and warm socks
- Teach stress-reduction techniques
- Encourage smoking cessation
- Instruct the client to avoid medications that can trigger attacks
- Educate the client about proper skin care to prevent skin breakdown
- Advise the client to inspect their fingers and toes regularly for sores or ulcers
Potential Complications
- Severe Raynaud's can lead to skin ulcers or tissue damage due to lack of blood flow
- In rare cases, it can lead to amputation of affected fingers or toes
- Secondary Raynaud's can cause complications related to the underlying condition
Medications
- Calcium channel blockers (e.g., nifedipine, amlodipine) relax blood vessels and improve circulation
- Vasodilators (e.g., nitroglycerin cream) can be applied to the affected area to increase blood flow
- Alpha-blockers counteract the effects of norepinephrine, a hormone that constricts blood vessels
- In severe cases, prostaglandins may be used to dilate blood vessels and prevent blood clots

Description
Raynaud's disease is a condition affecting blood vessels, causing them to narrow when exposed to cold or stress. This constriction reduces blood flow, leading to symptoms like numbness and color changes. Primary Raynaud's has no known cause, while secondary Raynaud's is caused by underlying conditions.
