Open-Cardiac Surgical Operating Room:
Cardiac surgical operating room in Razi Hospital was opened since
2007; many surgeons cooperated with this hospital using equipment and
facilities for monitoring patients.
Since 2007, 1521 patients had a surgical procedure and the most
common diseases are coronary artery diseases which is approximately 90.50%,
valves disease are 14.52% and other types of heart diseases are 35.37%.
Needed surgical procedures for rare form of heart diseases and
high risk ones, were performed by skilled surgeons of the hospital. The
patients who were coming from other cities, came back to their home city safe
Patients in this ward need different types of surgical procedures.
The morbidity rate of cardiac
surgeries in this center (infection, kidney problems, post-surgery problems and
so on) is less than 3 percent which in comparison to statistical center around
the world, this center has an acceptable standard.
morbidity rate in this setting is almost 1 percent and comparing to other
countries rate and considering that patients are at high risk, this number is
significant and valuable.
Available Equipment in this Ward
Anintra-aortic balloon pump, orIABP:
In this method, a cylindrical
balloon is inserted into descending aorta through the femoralartery and then it
is inflated after the contractions of atrial systole in the left
ventricle and during the closure of the aortic valve; so, thecoronary artery perfusion
is increased in size and as a result, it will decrease the oxygen supply.
IABP device uses this mechanism to
improve circulation and lower pressure on cardiac. The gas used in this balloon
is carbon dioxide (which reduces the risk of bursting) or helium (which has the
most capability to release).
Heart-lung machine does
the work of both the heart and the lungs such as circulation,
oxygenating blood. It is a temporary alternative for pulmonary circulation. This
device is used for open-heart surgeries, including implant of coronary artery
bypass, and also replacing different heart valves. These surgeries need
bloodless surgery techniques.In
some cases, cardiopulmonary bypass is used to provide
extracorporealmembrane oxygenation for patients with sleep apnea Syndrome or shortness
of breath which is the result of pneumoniaor
An arterial-blood gas test, called
ABG in medical sciences, is a kind of test that measures the amounts of oxygen
pressure and also blood PH level based on a blood sample collected from radial artery.
Unlike most blood tests that blood
sample is collected from vein, this blood sample is collected from an artery.
In this test, blood oxygen is measured; oxygen molecules are carried from lung
to body tissues, carbon dioxide which is produced by body cell (during
metabolism) is also transferred to lungs, kidney and liver.
Sample is obtained by using a
special narrow needle and it should be collected by a doctor or a skilled
nurse. Blood sample is usually collected from radial artery in wrist.
In open-heart surgery for cardiopulmonary bypass, surely blood clotting will occur because blood is in contact with an external system, so heparin is given by injection right before surgery. Screening test is used to determine injected heparin effectiveness which is called Activated Clotting Time (ACT).
This device is used in patients
with AF (an irregular and often rapid heart rate) or those who
have problems in their mitral valve.
