A Honor Society of Nursing (STTI) answered. The rate of incidence for pancreatitis each year in the United States is over 300,000 people. Roughly 200,000 people are hospitalized each year for treatment of acute pancreatitis.
As reported in Diabetes Technology & Management, recent research shows that smaller 8 millimeter (mm), 6 mm, and 4 mm needles are as effective, regardless of body mass. This makes insulin injections more acceptable and less painful than it was in the past.
Drugs administrated SubQ will usually be injected using an insulin syringe (also known as a 'slin pin'). The insulin syringe holds a maximum of 1ml, and has small increments for when dealing with small volumes of medicine. The increments go up in 10's, all the way up to 100, which is one ml. So, '50' on the barrel is half a ml, and '100' on the barrel is one ml.
