Caring for a patient after
coronary artery
bypass graft
surgery
Follow this system-by-system
approach to keeping your
patient stable and steering clear
of complications.
By Margaret Mullen-Fortino, RN, MSN,
and Noreen O’Brien, RN, MSN
EVERY YEAR, some 427,000 patients in the United States
have coronary artery bypass graft (CABG) surgery.1
Whether the surgery is done with the patient on or off the
cardiopulmonary bypass (CPB) machine (see On pump or
off?), the postoperative nursing care is the same. In this article, we’ll outline your role in patient care by body system.
Reducing risks for surgical patients is one goal of the
Institute for Healthcare Improvement’s (IHI’s) 5 Million Lives
Campaign, which aims to prevent 5 million incidents of
medical harm in the period from December 2006 to December 2008. See the resources list at the end of this article for
more information.
Safeguarding cardiac function
Twenty-four to 48 hours after surgery, your patient will be
transferred from the intensive care unit to the cardiac surgical unit and placed on continuous telemetry monitoring. Your top priority is to keep him hemodynamically
stable so his vital organs are adequately perfused. Check

his vital signs according to your facility’s protocol, or at
least every 4 hours, and assess for signs and symptoms of
adequate cardiac output. Investigate even subtle signs of
trouble, such as tachycardia and cool extremities. Other
signs of reduced cardiac output include diminished
peripheral pulses, changes in mentation, decreased urine
output, and hypotension.
Dysrhythmias, most often tachydysrhythmias, are
common after CABG and usually occur on the second or
third postoperative day. Atrial fibrillation (AF) occurs in
15% to 40% of patients after CABG, in 37% to 50% of
patients after valve surgery, and in up to 60% of patients
who’ve had CABG and valve surgery. A rapid ventricular
response and loss of atrial kick can cause myocardial
ischemia or reduce cardiac output and blood pressure
(BP). Patients with hypokalemia and hypomagnesemia
may be more prone to AF. Factors that increase your
patient’s risk of AF include:
• older age
• mitral valve disease
• history of AF
• chronic obstructive pulmonary disease (COPD)
• not having received preoperative beta-blocker or
angiotensin-converting enzyme inhibitor therapy or withdrawal of previous therapy.2
Preoperative or early postoperative administration of
beta-blockers is considered standard therapy to reduce
the risk of AF after CABG.3 Amiodarone is an alternative
for patients who have contraindications to beta-blockers.
Rate control for AF is best achieved with beta-blockers.
Digoxin or calcium channel blockers are used to control
ventricular rate but haven’t shown a consistent benefit in
reducing the incidence of AF after CABG.
If your patient develops AF, his stroke risk is two to
five times higher. The American College of Cardiology/
American Heart Association provides consensus guidelines for administering anticoagulation to patients with
AF lasting more than 24 hours.4 Because heparin is associated with increased bleeding risk, the patient may start
warfarin therapy without also starting heparin. However,
for high-risk patients, such as those with history of stroke
or transient ischemic attack, heparin should be considered as a bridging therapy to oral warfarin until the
patient’s international normalized ratio is therapeutic.
Ventricular dysrhythmias can occur any time after
CABG surgery but are more common in the early postoperative period. Hypothermia, electrolyte disturbances
(especially hypokalemia and hypomagnesemia), acidosis,
manipulation of the heart, and myocardial ischemia may
be factors in postoperative dysrhythmias. Bradycardias
and transient heart blocks usually resolve within several
hours after surgery. The patient will come out of the
operating room with epicardial pacing wires and a temporary pacemaker that are used for atrioventricular pacing
until normal conduction returns.
A pericardial effusion can result in cardiac tamponade,
a rare but potentially lethal complication following
CABG. Most cases occur in the early postoperative period, but tamponade can occur as late as 6 months postoperatively. Pericardial effusion puts pressure on the heart,
prevents diastole and filling of the chambers, and reduces
cardiac output. The hallmark of cardiac tamponade is the
Beck triad: muffled heart sounds, distended jugular neck
veins, and hypotension (see Assessing for cardiac tamponade). Pulsus paradoxus greater than 12 mm Hg is a classic sign of tamponade. Patients may experience dyspnea,
chest pain, and dizziness.
If your patient has signs and symptoms of cardiac tamponade, the physician may order a bedside echocardiogram. If it confirms tamponade, prepare your patient to
On pump or off?
During “on pump” CABG surgery, a CPB machine circulates oxygenated blood while diverting most of the patient’s blood
from the heart and lungs. This provides a bloodless, motionless surgical field while preserving tissue perfusion to vital
organs. The blocked coronary artery is bypassed using a graft from the saphenous vein or the IMA or radial artery.
However, CPB puts patients at risk for various problems related to the blood being in contact with the machine, including
atrial fibrillation, systemic inflammatory response syndrome, stroke, cognitive changes, renal failure, dysrhythmias, coagulopathies, and microemboli.
The older “off pump” technique, in which surgery is performed on the beating heart, reduces the adverse reactions
associated with CPB and the need for RBC transfusions and positive inotropes. However, a meta-analysis found no significant differences in mortality rates, myocardial infarction, stroke, or renal dysfunction between the two types of CABG,
and no consensus has been reached on which procedure is better.

return to the operating room for evacuation of
the clot and repair of the bleeding site. But if
the patient’s condition deteriorates to the
point that he’s at risk for cardiac arrest, the
physician may perform an emergency bedside
reexploration sternotomy.
Pulmonary problems
Between 30% and 60% of patients have pulmonary dysfunction and hypoxemia after
CABG, usually as a result of fluid volume
overload, poor inspiratory effort, and atelectasis. Risk factors for pulmonary problems
include a history of heart failure, COPD,
smoking, or diabetes; age over 65; and endotracheal intubation. Common signs of respiratory impairment are shortness of breath and
decreased oxygen saturation as shown on
pulse oximetry.
Atelectasis, a common postoperative complication, may be related to CPB, effects of
general anesthesia, and decreased surfactant production
from the patient being on CPB.
Pleural effusion, another common complication, occurs
in the immediate postoperative period in 41% to 87% of
patients. Effusions can result from bleeding secondary to
internal mammary artery (IMA) harvesting. Small effusions
(less than 500 mL) can be managed conservatively and will
usually resolve spontaneously. Larger effusions may require
thoracentesis, especially if they cause dyspnea or other
signs and symptoms. (See Picking up on pleural effusion.)
To reduce your patient’s risk of postoperative pulmonary complications, assess breath sounds frequently,
monitor his SpO2, administer supplemental oxygen as
needed, and encourage him to perform incentive spirometry every hour while he’s awake. Teach him to splint his
incision when coughing and moving. Be sure to provide
optimal pain control so he can move freely. Assisting the
patient with early, aggressive ambulation, coughing and
deep breathing, and turning from side to side while in
bed are simple but effective nursing interventions that
help prevent postoperative pulmonary complications.
Patients with copious pulmonary secretions or bronchospasm may also need chest physical therapy and nebulized bronchodilators.
Patients who need mechanical ventilation are at risk
for ventilator-associated pneumonia (VAP). The Institute
for Healthcare Improvement (IHI) recommends a fourpronged ventilator bundle of interventions:
• elevating the head of the bed 30 to 45 degrees except

when care is being given or if contraindicated; for example, because of hemodynamic instability
• providing a daily “sedation vacation” to evaluate the
patient’s readiness for weaning
• taking steps to prevent venous thromboembolism
(VTE) (more on this later)
• administering daily medication (such as a histamine2receptor inhibitor) to prevent peptic ulcer disease.5
Keeping pain under control
Besides keeping the patient comfortable, effective pain
control helps maintain hemodynamic stability and prevent pulmonary complications. (The pain of a sternotomy can impair breathing patterns.) The typical patient
will receive intravenous (I.V.) push opioids in the immediate postoperative period, then switch to oral forms by
the second or third postoperative day as tolerated.
Analgesics, positioning, distraction, and relaxation techniques also can be used to control pain.
Monitor the patient for adverse drug reactions, such as
oversedation and respiratory depression. Balance his need
for pain control without respiratory depression with his
need to cough and deep-breathe. Individualize pain management and frequently evaluate the patient’s pain, using
an appropriate pain intensity rating scale, to check the
effectiveness of interventions. Also use a sedation-rating
tool to monitor for sedation and respiratory depression.
Besides opioids, I.V. ketorolac, a nonsteroidal antiinflammatory drug (NSAID), may be used with caution

Picking up on pleural effusion
in patients who don’t receive adequate pain control from opioids alone. Check the patient’s
renal function before administering this drug
and expect to discontinue it if his serum creatinine increases. Also remember that NSAIDs can
increase the patient’s risk of gastrointestinal
(GI) bleeding. Monitor for signs and symptoms
of occult bleeding.
Another source of moderate to severe pain is
chest tube removal, which usually occurs on the
first or second postoperative day. Administer
adequate analgesia before chest tube removal.
Staying alert for coagulation problems
Bleeding is a common complication after CABG
surgery and can have many causes, including
platelet dysfunction from prolonged contact
with the artificial surface of the CPB machine,
high doses of heparin given during surgery, and
hypothermia.
A patient who’s actively bleeding and has a
hematocrit less than 26% needs a transfusion of
red blood cells (RBCs) to improve the blood’s oxygencarrying capabilities and to limit myocardial ischemia or
infarction.6 These benefits must be balanced with the risks
of RBC transfusion, including acute lung injury, prolonged
mechanical ventilation, infection, sepsis, and renal dysfunction. Six- to 12-month follow-up studies of patients
who’d undergone cardiothoracic surgery have shown that
the more packed RBCs a patient receives, the worse his
postoperative functional status.7
Also take steps to prevent VTE, which encompasses
deep vein thrombosis and pulmonary embolism. The
Surgical Care Improvement Project’s guidelines, which
are supported by IHI, call for prophylactic drug and
mechanical therapy to prevent VTE. As ordered, use
intermittent pneumatic compression devices and graduated compression stockings and administer low-dose
unfractionated heparin, low-molecular-weight heparin,
factor Xa inhibitor (fondaparinux), or warfarin. Aspirinonly therapy isn’t recommended, and early ambulation
isn’t included in the recommendations because most
patients only make trips to the bathroom or take short
walks down the hall—insufficient activity to prevent
VTE.8
Renal troubles
Postoperative renal dysfunction occurs in as many as 8%
of patients after CABG. Predictors of renal dysfunction
include advanced age, history of moderate or severe heart

failure, prior bypass surgery, type 1 diabetes, and preexisting renal disease.
Because of fluid retention, most patients are still significantly above their preoperative weight when they’re
transferred to the medical/surgical unit after CABG. A
comparison of the patient’s postoperative daily weights to
his preoperative weight guides the use of diuretics.
Monitor his urine output, blood urea nitrogen level, and
serum creatinine level to assess renal function.
Diuretics typically are given on the first postoperative
day and are continued until the patient reaches his preoperative weight (usually in 5 to 7 days). Patients who needed diuretics before CABG may need to continue taking
them after discharge. If the patient develops oliguria
(urine output of less than 0.5 mL/kg/hour), assess his cardiac function and perfusion, vital signs, and lab results.
He may need fluids or medication dose adjustments.
GI glitches
Less common, GI complications affect 1% to 2% of
patients after CABG. The most common major complications are upper GI bleeding from gastritis or peptic ulcer
disease, pancreatitis, hollow viscus perforation, mesenteric ischemia, and cholecystitis.6 Monitor the patient’s
bowel sounds and notify the health care provider if the
patient develops abdominal pain, distension, nausea, and
vomiting. The patient may need diagnostic tests includwww.nursing2008.com
ing an abdominal X-ray, electrolyte panel, and complete
blood cell count.
Most patients have a nasogastric (NG) tube immediately after CABG surgery. The NG tube usually is removed
after the patient is extubated and after his bowel sounds
return. He then can be started on clear liquids and his diet
advanced as tolerated.
Anorexia and nausea are common postoperative complaints and may be adverse drug reactions. Administer
antiemetics if the patient is nauseated and give histamine
blockers as prescribed to minimize gastric acid secretion.
Treat constipation, another common postoperative problem, with stool softeners or bulk laxatives as ordered.
approaches, your patient and his family may be anxious
about how they’ll manage at home, so try to ease the
transition. Appropriate discharge planning should
involve the patient, caregivers, nurses, physicians, and
nutritionists because a team approach is the best way to
treat factors that contribute to heart disease. Give the
patient detailed instructions about:
• when to contact the hospital or health care provider.
Tell the patient to seek immediate medical attention if he
has chest pain, shortness of breath not relieved by rest, a
fast or irregular heartbeat, chills, fever, severe headache,
numbness or tingling in his arms or legs, fainting spells,
or if he coughs up bright red blood.
• what to expect and what’s normal after surgery. Mood
swings, diminished appetite, and difficulty sleeping are
common after CABG, but usually resolve in 4 to 6 weeks.
• lifestyle changes such as stopping smoking, eating a
low-fat diet, controlling BP, and losing weight. For example, patients who continue to smoke have more
