Acute pancreatitis or acute pancreatic necrosis is a sudden inflammation of the pancreas. It can have severe complications and high mortality despite treatment.
The needles themselves are categorized by length as well as the needle's gauge, indicating the overall thickness of the needle. Contrary to most measurement systems, the higher the needle's gauge, the smaller it actually is. Insulin syringes, for example, are found in three common sizes: 1 cc, 1/2 cc, and 3/10 cc. The correct size syringe to use is determined by the average size of the dose of insulin that the patient administers. An insulin syringe also can be categorized by how many units of insulin it is designed to hold.
1 The type of insulin should match the type of syringe: U-100 or U-500. Because U-500 syringes may be difficult to find, your health care provider may give you instructions for using U-500 insulin with U-100 syringes.  Some types of insulin can be mixed with each other in one syringe, but not all.
