Capital & Coast DHB Cardiothoracic Service
Blood tests are carried out before and after cardiothoracic operations. They measure such things as how the kidneys are working, cardiac markers (to make sure the heart is healthy) and levels of potassium (K+) and calcium (Ca++) as well as other elements. These are some of the indicators of how the body is working and can show how well a patient’s body is coping with their illness. Intra-arterial and intravenous lines (tubes placed in arteries and veins) are often used to monitor the body and, once established, allow rapid, reliable and pain-free access for repeated blood tests. Some conditions will require multiple repeated blood testing every few hours.
