4 Cardiac Catheterization Nursing Care Plans and Management

Most of the work in cardiac catheterization happens after the patient leaves the cath lab. The catheter punctures a major vessel, usually the femoral, so your postprocedure priorities are the puncture site, distal perfusion, and the contrast load on the kidneys. For pediatric patients, add the child's fear and the parents' anxiety to the list. Catch a bleed or a cold, pulseless extremity early and you prevent the serious complications.

What is cardiac catheterization?

Cardiac catheterization is an invasive procedure that threads a flexible catheter into the heart through a vein or artery, usually the femoral vein. It is diagnostic and therapeutic, often paired with angiography and contrast media to visualize blood flow. It measures blood gases, pressures, and cardiac output and identifies defects like septal defects or obstructions. Therapeutic catheterization uses balloon angioplasty to correct stenotic valves or vessels, aortic obstruction, and patent ductus arteriosus.

Nursing Care Plans and Management

For a child undergoing cardiac catheterization, the goals are adequate perfusion, reduced fear and anxiety, good teaching, and injury prevention. Close postprocedure monitoring catches complications early and lowers mortality and morbidity.

Nursing Problem Priorities

1. Promote adequate tissue perfusion. These patients are at risk for bleeding, vascular injury, and impaired perfusion. Monitor closely.
2. Prevent injury and control infection. The insertion site and bloodstream can become infected. Use strict aseptic technique, watch for signs of infection, and give proper wound care.
3. Reduce fear and anxiety. The invasive procedure, possible complications, and uncertain outcome drive anxiety. Emotional support, education, and relaxation help.

Nursing Assessment

Assess for the following subjective and objective data:

• Decreased or absent pulses distal to the catheterization site
• Cool, mottled affected extremity
• Tingling in the affected extremity
• Pain
• Increased body temperature within a few hours postoperatively
• Concern over the procedure, apprehension
• Increased motor activity in children, inattention, clinging to a parent, crying, verbal protests, withdrawal
• Decreased level of consciousness
• Increased apical heart rate and decreased blood pressure
• Bleeding from the catheterization site, bruising

Assess for factors related to the cause:

• Clot formation at the puncture site
• Reaction to the radiopaque contrast
• Fear of needles and exposure
• Invasive, painful procedure
• Separation from parents
• Risk of harm
• Altered hemostasis and trauma from the percutaneous puncture

Nursing Diagnosis

A nursing diagnosis identifies the patient's specific needs and responses to cardiac catheterization and guides a customized care plan.

Nursing Goals

• The patient's involved extremities will be pink and warm.
• Pulses will be present distal to the catheterization site and equal bilaterally.
• The child's axillary temperature will stay below 100°F.
• The child will not cry, cling to parents, or protest.
• Parents will verbalize decreased anxiety.
• The child will not bleed from the puncture site.
• Heart rate and blood pressure will stay within normal limits.

Nursing Interventions and Actions

1. Promoting Adequate Tissue Perfusion
2. Regulating Body Temperature
3. Reducing Fear and Anxiety
4. Preventing Injury and Infection from Contrast Medium

1. Promoting Adequate Tissue Perfusion

The puncture site can clot and obstruct distal blood flow, so perfusion checks are the core of postprocedure care.

1. Assess the affected extremity for color, temperature, and capillary refill. Palpate distal pulses and use Doppler every 15 minutes for 4 times, every 30 minutes for 3 hours, then every 4 hours. A clot at the puncture site can obstruct distal flow and damage tissue. Frequent checks let you intervene fast.

2. Keep the patient on bed rest with the affected extremity straight or with a slight knee bend (10 degrees) for 6 hours. Improves circulation and minimizes trauma that could promote a clot.

3. Provide warmth to the opposite extremity. Boosts blood flow without raising bleeding risk at the site.

4. Tell parents and child why frequent vital signs and bed rest with the extremity extended matter. Promotes cooperation.

2. Regulating Body Temperature

Contrast can trigger a reaction that raises temperature and demand on the heart. Hydration flushes the dye and protects the kidneys.

1. Assess temperature every hour for 6 hours, then routine. Guides your next action.

2. Monitor and record intake and output hourly. Tracks fluid balance.

3. Maintain IV fluids while the child is drowsy. Once fully awake, encourage oral fluids. Fluid intake flushes out the dye.

4. Have parents encourage oral fluids. Including parents improves the odds of meeting the goal.

5. Teach parents to monitor the child's temperature at home and report elevations after discharge. Lets parents watch for hyperthermia.

3. Reducing Fear and Anxiety

Fear and anxiety raise the child's perception of pain and can affect hemodynamic stability. Address them with preprocedure education, parental presence, and relaxation.

1. Assess the parents' and child's understanding of the procedure and any specific fears. Parents fear the procedure, the child's pain, complications, and the outcome. Children fear separation, the unknown, mutilation, death, or remembered pain from a prior catheterization.

2. Encourage expression of fears and clear up misconceptions. Lets the family share feelings and gives them accurate, complete information.

3. Prepare the child with age-appropriate explanations, given just before each event for younger children. Cover what the child will experience through all senses. Young children process through their senses and cope better knowing what to expect.

4. Let parents stay with the child and be present when the child wakes postoperatively. Children adjust to stress better with their parents present.

5. Suggest the family bring a familiar comfort item: a blanket, pillow, or stuffed toy. A familiar object provides security in an unfamiliar setting.

6. Explain the reason for each pre and postcatheterization procedure. Understanding promotes acceptance.

7. Tell parents the child may act differently at home for a while: clinging, bad dreams, less self-sufficiency. Encourage them to comfort and reassure the child, let the child re-live the experience through stories or play, and accept temporary developmental setbacks. Stressful events can cause temporary regression, and children replay stress through play to cope.

4. Preventing Injury and Infection from Contrast Medium

Contrast can cause allergic reactions or renal injury, and the insertion site can become infected. Watch vital signs, use sterile technique, and keep pressure on the site.

1. Monitor vital signs every 15 minutes for 4 times, every 30 minutes for 3 hours, then every 4 hours. Vital sign changes can be the first sign of blood loss or internal bleeding.

2. Gather baseline labs from the precatheterization assessment. Provides comparison data for postprocedure assessment.

3. Assess the affected extremity for color, temperature, and capillary refill. Palpate distal pulses and use Doppler every 15 minutes for 4 times, every 30 minutes for 3 hours, then every 4 hours. A clot at the puncture site can obstruct distal flow and damage tissue. Frequent checks let you intervene fast.

4. Keep the pressure dressing on and assess for bleeding every 30 minutes. If bleeding occurs, apply continuous direct pressure 1 inch above the puncture site and notify the physician immediately. Constant direct pressure stops bleeding. No bleeding, not even oozing, is acceptable.

5. Maintain bed rest for 6 hours postcatheterization as ordered. Bed rest avoids strain that could trigger bleeding. Head elevation to 45 degrees with a slight knee bend is acceptable. Young children may be held by parents, which reduces agitation.

6. Keep the affected extremity straight or with a slight knee bend (10 degrees) for 6 hours. Improves circulation and minimizes trauma that could promote a clot.

7. Provide warmth to the opposite extremity. Boosts blood flow without raising bleeding risk at the site.

8. Tell parents and child why frequent vital signs and bed rest with the extremity extended matter. Promotes cooperation.

9. Encourage quiet activities such as storytelling and music. Allows interaction without physical stress and provides distraction.

10. Inform parents and child of the need for periodic monitoring and bed rest. Promotes cooperation.

11. Encourage parents of infants and young children to hold them as a way to rest in bed. Lets parents comfort the child normally and reduces agitation, encouraging rest.

12. Teach parents to watch for and report any bleeding immediately. Explain that the pressure dressing comes off after 24 hours, after which they should keep assessing the site and report any bleeding to the physician. Keeps close watch on the site.
