Study Notes
Cardiac Surgery
- Heart disease is the leading cause of death worldwide.
- Cardiac surgery may be used as a treatment when heart disease symptoms increase in severity and frequency or the disease process worsens.
Heart Structure and Function
- The heart has four chambers: the left and right atria, and the left and right ventricles.
- Four valves regulate blood flow through the heart: tricuspid valve, pulmonary valve, mitral valve, and aortic valve.
- Coronary arteries supply the heart muscle with blood.
Coronary Artery Revascularization
- Coronary artery bypass grafting (CABG) is a surgical procedure in which a blood vessel from another part of the body is grafted to the occluded coronary artery.
- CABG allows blood to flow beyond the occlusion.
Patient Assessment
- Respiratory status: chest movement, breath sounds, ventilator settings, respiratory rate, ventilatory pressure, arterial oxygen saturation, and pleural chest tube drainage.
- Peripheral vascular status: peripheral pulses, skin color, nailbeds, mucosa, lips, and ear lobes, skin temperature, edema, and condition of dressings and invasive lines.
- Renal function: urinary output, urine specific gravity, and osmolality.
- Fluid and electrolyte status: intake, output from all drainage tubes, and cardiac output parameters.
- Pain: nature, type, location, duration, and response to analgesics.
Assessing for Complications
- The patient is continuously assessed for indications of impending complications.
- The nurse and surgeon collaborate to identify early signs and symptoms of complications and institute measures to reverse their progression.
Complications
- Decreased cardiac output: a threat to the patient who has had cardiac surgery, symptoms include restlessness, headache, confusion, dyspnea, hypotension, and cyanosis.
- Decreased cardiac output can lead to hypoxia.
Nursing Diagnoses
- Decreased cardiac output related to blood loss, compromised myocardial function, and dysrhythmias.
- Impaired gas exchange related to trauma of extensive chest surgery.
- Risk for deficient fluid volume (and electrolyte imbalance) related to alteration in circulating blood volume.
- Disturbed sensory perception (visual or auditory) related to excessive environmental stimuli, insufficient sleep, psychological stress, altered sensory integration, and electrolyte imbalances.
- Acute pain related to surgical trauma and pleural irritation caused by chest tubes.
- Ineffective tissue perfusion (renal, cerebral, cardiopulmonary, gastrointestinal, peripheral) related to decreased cardiac output, hemolysis, vasopressor drug therapy, venous stasis, embolization, underlying atherosclerotic disease, effects of vasopressors, or coagulation problems.
- Ineffective thermoregulation related to infection or postpericardiotomy syndrome.
- Deficient knowledge about self-care activities.
Continuing Care
- Arrangements are made for a home care nurse to provide care when appropriate.
- The education plan is continued by the home care nurse.
- Vital signs and incisions are monitored, the patient is assessed for signs and symptoms of complications, and support for the patient and family is provided.
Expected Patient Outcomes
- Maintains adequate cardiac output.
- Maintains adequate gas exchange.
- Maintains fluid (and electrolyte) balance.
- Experiences decreased symptoms of sensory-perception disturbances.
- Experiences relief of pain.
- Maintains adequate tissue perfusion.
- Maintains normal body temperature.
- Performs self-care activities.
Prevention of Coronary Heart Disease
- Lowering blood pressure and cholesterol levels can help reduce the risk of developing coronary heart disease.
Aneurysms
- Aneurysms can occur anywhere, but the most common occur in the aorta, brain, leg behind the knee, intestine, and spleen.
- Symptoms may develop suddenly and include pain, clammy skin, dizziness, nausea and vomiting, rapid heart rate, shock, and low blood pressure.
Treatment and Prevention of Aneurysms
- Surgery may be performed to repair or remove the damaged tissue.
- The type of surgery depends on the patient's overall health and the type of aneurysm.
Nursing Care for Aneurysms
- Assess peripheral perfusion.
- Monitor hemodynamics and vital signs to monitor for deterioration.
- Manage pain.
- Administer antihypertensives.
- Monitor for evidence of rupture.
- Larger aortic aneurysms are at high risk for rupture.
