Post-Cardiac Catheterization Arm Care: Essential Steps

If the catheter was inserted via the radial artery (wrist) or brachial artery (arm), follow these precautions to prevent bleeding, hematoma, or nerve injury:

Immediate Care (First 24–48 Hours)

• Keep arm elevated above heart level when sitting/lying.
• Apply ice packs (wrapped) 15 min on/off to reduce swelling/bruising.
• No heavy lifting (>5 lbs) or vigorous motion (pushing, pulling, twisting).
• Keep insertion site clean & dry; follow dressing instructions.
• Take prescribed pain meds as needed.

Monitor for Complications

Contact your doctor immediately for:

• Increasing swelling, pain, or bruising
• Numbness, tingling, coolness, color change in hand/fingers
• Bleeding through dressing
• Signs of infection: redness, warmth, pus, fever >100.4°F (38°C)
• Absent radial pulse

Recovery Timeline

• Bruising/soreness: 1–2 weeks typical.
• Full activity: Usually cleared at follow-up (1 week).
• Radial artery occlusion: Rare (~2–5%); often asymptomatic due to collateral flow.

Always follow your cardiologist's specific discharge instructions—they supersede general guidance.
