JP drain: The original suction drain. The drain itself is inside the body. It is made of Teflon and has multiple drainage holes. The drain is connected to clear plastic tubing which is usually sutured to the skin at the point it leaves the skin. The tubing connects to a bulb reservoir. The bulb, when squeezed empty, applies constant suction to the drain and pulls the fluid out of the body.
Cardiac Enzyme Studies. Cardiac enzyme studies measure the levels of enzymes and proteins that are linked with injury of the heart muscle. These include the enzyme creatine kinase (CK), and the proteins troponin I (TnI) and troponin T (TnT).
A lipase test measures the amount of this enzyme in a blood sample. High amounts of lipase may be found in the blood when the pancreas is damaged or when the tube leading from the pancreas (pancreatic duct) to the beginning of the small intestine is blocked. A lipase test is done to: 1  Check for pancreatitis and other diseases of the pancreas. 2  See if the treatment for pancreatitis is working.  Help check for cystic fibrosis or see if treatment for it is working.
