1. Cardiac surgery involves opening the chest and operating on the heart using a heart-lung machine to circulate blood and allow surgeons to operate while the heart is stopped.
2. Post-operative care focuses on promoting cardiovascular, respiratory, renal and neurological function while preventing complications like hemorrhage, infection, and low cardiac output.
3. Care involves careful monitoring, managing fluids and electrolytes, early mobilization, and health education prior to discharge about activity limitations, medication management, and follow-up care.

CARDIAC SURGERY PRE & POST CARE
1. PRE & POST OPERATIVE CARE
OF PATIENT WITH CARDIAC
SURGERY
2. MEANING OF CARDIAC
SURGERY
It is an surgical procedure in
which the chest is opened and
surgery is performed on the
heart. The term "open" refers to
the chest, not to the heart
itself..
3. COMMON DISORDERS
REQUIRING CARDIAC SURGERY
•coronary artery disease
•aortic valve disease
•mitral valve disease
•Congenital heart disease
7. TYPES OF CARDIAC SURGERY
:
Closed
Two types
Open Heart Surgery
Heart Lung Machine or Pump- oxygenator
Operate for longer time
Direct Visualisation
8. Cardiac Surgery- cardioplegia
• To achieve this, the patient is first placed on
cardiopulmonary bypass. This device,
otherwise known as the heart-lung machine,
takes over the functions of gas exchange by the
lung and blood circulation by the heart.
Subsequently the heart is isolated from the rest
of the blood circulation by means of an
occlusive cross-clamp placed on the ascending
aorta proximal to the innominate artery.
9. • During this period of heart isolation the heart
is not receiving any blood flow, and thus no
oxygen for metabolism. As the cardioplegia
solution distributes to the entire myocardium
the ECG will change and eventually asystole
will ensue. Cardioplegia lowers the metabolic
rate of the heart muscle thereby preventing cell
death during the ischemic period of time.
10.
11. PURPOSES OF
HEART LUNG MACHINE
To provide the surgeon with a bloodless
operating field.
To perform gas exchange functions.
To filter, re-warm or cool the blood.
To circulate oxygenated , filtered blood
back to arterial system.
