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.
Some insulin pens contain a cartridge of insulin that is inserted into the pen and some are pre-filled with insulin and discarded after all the insulin has been used. The insulin dose is dialed on the pen, and the insulin is injected through a needle, much like using a syringe. Cartridges and pre-filled insulin pens only contain one type of insulin. Two injections must be given with an insulin pen if using two types of insulin.
