Intravenous sugar solution

An intravenous sugar solution is a solution with a sugar (usually glucose, also known as dextrose, with water as the solvent) used for intravenous therapy, where it may function both as a means of maintaining tissue hydration and a means of parenteral nutrition. Most IV sugar solutions are crystalloid solutions.


Types of glucose/dextrose include:

The percentage is a mass percentage, so a 5% glucose/dextrose solution contains 50 g/L of glucose/dextrose (Quite simply, 5% dextrose means the solution contains 5g/100ml of solution).

Glucose provides energy 4 kcal/gram, so a 5% glucose solution provides 0.2 kcal/ml. If prepared from dextrose monohydrate, which provides 3.4 kcal/gram, a 5% solution provides 0.17 kcal/ml.[2]


Administering a 5% sugar solution peri- and postoperatively usually achieves a good balance between starvation reactions and hyperglycemia caused by sympathetic activation. A 10% solution may be more appropriate when the stress response from the reaction has decreased, after approximately one day after surgery. After more than approximately 2 days, a more complete regimen of total parenteral nutrition is indicated.

In patients with hypernatremia and euvolemia, free water can be replaced using either 5% D/W or 0.45% saline.

In patients with fatty-acid oxidation disorders (FOD), 10% solution may be appropriate upon arrival to the emergency room.


Intravenous glucose is used in some Asian countries as a pick-me-up, for "energy," but is not a part of routine medical care in the United States where a glucose solution is a prescription drug. Asian immigrants to the United States are at risk if they seek intravenous glucose treatment. It may be had at store-front clinics catering to Asian immigrants, but, despite having no more effect than drinking sugared water, poses medical risks such as the possibility of infection. The procedure is commonly called "ringer."[3]

Although many doctors warn Asian immigrants in New York that the effects of injecting glucose differ little from drinking sugary water, many Asians, especially of older generations, still use the intravenous solution. In their homelands, it is commonly prescribed by doctors as a method to cure colds, fevers and sometimes an upset stomach.
