of the chest through the breastbone. The incision may
hurt medication will be given to relieve the pain.
Sometimes it causes heavy perspiration during
the night or even the day. Taking medicines usually brings
after the surgery.
What can be done to help recovery ?
Deep breathing exercises and coughing are important
way to speed recocery. Coughing reduces the chances of
pneumonia and fever and will not harm the incision or
bypass grafta. Most patients will have fear of pain,
discomfort and don't like to cough after an operation, still
coughing is essential. Some patients find it easier to cough
if a pillow supports their chest. You can help our own

Eventually they can climb stairs and take brisk, longer
walks to prepare for going home.
What can you do to help yourself after returning home ?

Watch your weight.
Watch your cholesterol level.
Keep physically active.

It depends up on a patient's need and the wishes of your
cardiovascular surgeon. Patients usually are advised
about future surgical appointments when they are
discharged from the hospital. You should see
cardiologist reqularly and have intervals to assess
progress. You should doctor soon after returning home.
How long will you have to wait before returning to
If you perform a sedentary job, the average is
between three to six weeks. If your job involves heavy

Will there be restrictions on driving an automobile ?
You may begin driving any time you feel
physically able to operate the vehicle safely. It is
usually best to wait a few weeks after leaving the
hospital to begin driving a car.
When to do awake bypass surgery ?
Specially good for patients with.
Severe lung disease.
Severe liver disease.
Past history of stroke/ unconsciousness.
High risk general anesthesia.
When not to do ?
Poor ventricular function ( 25%).
Diffuse coronary disease.
Benefits for the patients
No general anesthesia.
Can be performed for high-risk group of
patients who were earlier termed in- operable
because of risk of general anesthesia.
No post-operrative ventilator support required which
reduces post-operative intensive care to less than
Overall hospitalization can be reduced by 3 days.
Preparing for your surgery typically a patient is admitted
to the hospital with enough time the operation date to
allow diagnostic tests to be done. These routinely include
blood and urine tests, electrocardiograms (ECGs),
chestx-rasy and so on. Cardiac catheterization with coronary
angiograms is done during the preoperative hospital
Who will you before the operation ?
Before the operation, members of the cardiac surgery
team will visit to examine you, discuss the details of the
operation and answer your questions.
The nursing staff will also evaluate your needs; make you
as comfortable as possible. In addition, the anesthesiologist
will evaluate you and discuss plans for the care or vital
body functions during the operation.
Other members of the technical staff may come to draw
blood, instruct you about how to breathe and care for your
lungs after the operation. You will also be told when the
operation will occur.
What is per-donation for blood transfusion?
If you can found to be fit, one or two bottles of your own blood may be drawn before surgery which will be used for blood transfusion, during or after surgery. It is the safest blood transfusion and liminates or reduces the need for donor blood transfusion. This may be done before or after your admission, on the decision of your cardiovascular surgeon.
What preparations need to be done for the operation?
Before the operations,most of your body hair will be shaved off, especially from your chest and legs, you will probably be asked to shower and wash with to remove bacteria from the skin to reduce the chance of infection.

Your family can wait in front of the operation theatre during the surgery or at the reception. Be sure surgeon knows where your family will be waiting.
After the operation patient is taken to recovery area or an intensive care unit(ICU). Amember of the family may visit briefly in the recovery or intensive care unit after a few hours of the operation when the patient is awake.
How long is the convalescent period in the hospital ?
The usual hospital stay after an operation is from normally 5 to 7 days. However patients who undergo the minimally invasive coronary bypass surgery (MICAS) can return home within 3-4 days. During that period and beyond, most patients have “good days” and “bad days” with overall progress and gain in strength.
What is coronary artery disease ?
Ageing and other complex factors cause the blood vessels to become hard . In addition,
cholesterol and minerals from the inner deposited on the coronary arteries. When this
material builds up, they from a plaque. A raised plaque may restrict the blood flow
through the coronary artery.
A rasied plaque may also change the surface of the artery from smooth to rough, and
these roughsurfaces may stimulate the formation of a blood clot, which may lead to
narrowed artery. A blood clot can also build up quickly and abruptly close of the artery.
What is coronary artery bypass graft (CABG) surgery ?
Coronary artery bypass graft surgery is an open-heart operation in which arteries or
veins are taken from another part of the body to channel needed blood flow to the
coronary arteries or veins are connected directly to the coronary arteries on the surface
of the heart beyond the blockages. This way blood can flow through them to bypass
the narrowed or closed points.
Coronary artery bypass graft operations usually last from there to six hours, their
duration depending on the number of vessels to be grafted. Each operation varies
in complexity, so its duration can only be estimated.
What is conscious off-pump coronary artery bypass surgery (awake bypass surgery)?
Awake bypass surgery is a break through step in “Fast-track care “of bypass surgery patients.
The 1990's witnessed significant advances in bypass surgery like
Elimination of heart lung machine
Awake bypass surgery is the latest advancement where a patient undergoes bypass
while actually awake and can converse with the operation surgeon and his team.
How is the performed ?
Anew type of beating heart surgery which is performed with apidural anesthesia,
eliminating the need and risks of general anesthesia. The technique is a highly precision- based
methodology, Which involves injection of micro doses of local anesthesia which anesthetizes only
the chest region while the rest of the system is fully awake. This enable a painless bypass surgery and
makes the surgery sage for patients who are at high risk for general anesthesia.
How is a awake bypass different ?
High thoracic eqidural anesthesia given instead of general anesthesia.
Which works like cardiac sympatheactomy.
Causes vasodilatation of internal mammary arteries and coronary arthritis.
Produces severe heart rate without hemodynamic compromise.
Leads to attenuation of stress response.
Gives favorable blood / oxygen supply/ demand ratio for myocardium
Provides effective pain control.
patient selection for awake CAB & procedure thoracic epidural anesthesia eliminates the
needs & risk of general anesthesia . With this technique anesthetic medicine is steadily
delivered to the pidural space of the spine. The patient medication is given to reduce anxiety and
the patient remains awake the entire surgery.
Avoidance of tracheal intubation.
Avoidance of Ventilation .
Avoidance of cardiac depression due to general anesthesia and premedication drugs.
Avoidance of ischemic events related to intubation .
No ventilator related problems.
No hoarness of voice due to intubation.
Reduced ICU stay.
Reduced Hospital stay.
