| [ Summary ] |
Nutrients used for percutaneous endoscopic gastrostomy (PEG) feeding can be classified into various categories. The first are those which can be a source of nitrogen whether artificial or natural. Further categories are those providing natural condensed liquid nutrients, semi-digested nutrients, digested nutrients, or elementary nutrients depending on the degree of decomposition of nitric sources. In terms of medical insurance policies, these nutrients are regarded as either medical/pharmaceutical products or food products. Degree of solution can classify them into powder-like nutrients, liquid nutrients or semi-solid nutrients. Methods of administration vary depending on the type of nutrients. If nutrients are liquid, they are dripped at slow administration rates with subjects kept in a head-up (over 30 degree) position. Semi-solid nutrients should be infused over a short period of time (appx. 3-5 min.) because responsive ballooning of the stomach cannot be induced by slow administration. |
