Parenteral nutrition (PN) is commonly known as intravenous feeding. The method enables getting nutrition in the body through the veins. PN is administered to patients only when they are unable to take the required nutrition through the gastrointestinal tract for a prolonged period of time. While in general PN may include a combination of carbohydrates and sugar, lipid, proteins, trace elements, and electrolytes, the solution administered may differ in combination depending on the patient’s condition. The rising prevalence of chronic illnesses such as diabetes, cancer, and others around the world has augmented the demand for PN. The global parenteral nutrition market is also gaining impetus from increasing cases of preterm babies, coupled with the expanding malnourished population in developing nations. According to the World Health Organization (WHO), inadequate nourishment accounts for over 11% of the worldwide burden of disease and is also identified as the number one risk to the wellbeing of any nation.

Driven by the increase in the number of approvals of novel parenteral nutrition formulas and the rising geriatric population worldwide, the global parenteral nutrition market, which stood at US$4.1 bn in 2014, will reach US$6.9 bn in 2023, states Transparency Market Research in its latest report.

Who Needs Parenteral Nutrition?
A patient may need parenteral nutrition irrespective of his age and depending on his condition. Parenteral nutrition, therefore, may be given to children and infants as well as adults. People can get nutrition via PN as long as it is needed. However, for the majority of cases, PN is administered for a short time and then it is removed when the patient no longer requires it and starts eating normally.
Under normal circumstances, digestion occurs inside the human body when food is broken down in the bowel and stomach and then absorbed in the former. These absorbed nutrients are then carried by the blood to the other parts of the body.
However in the case of parenteral nutrition, the course of normal digestion in the stomach is bypassed. PN is a special combination of liquid food mixture delivered directly to the blood through an intravenous catheter. This solution contains carbohydrates, proteins, vitamins, minerals, and fats.
Method of Supplying Parenteral Nutrition
The majority of medical practitioners and doctors place intravenous (IV) catheter in a large vein in the arm or chest of the patient. To administer the PN solution. This IV catheter can stay in place as long as needed. However, it is very important for nurses or other healthcare professionals to take proper care in order to avoid clotting and infection. Various catheters are used for supplying PN. Some of the most commonly used catheters include PICC, Broviac, triple lumen, ports, and double lumen or single lumen catheters.
