Glucose supplements

Monosaccharides absorbed from intestine after PO absorption of dextrose results in rapid increase of blood glucose concentrations.


Should be given to any obtunded patient in whom hypoglycemia cannot be rapidly ruled out via bedside testing. Monosaccharide, absorbed from intestine and distributed, stored, and used by tissues. Parenterally injected dextrose is used in patients unable to obtain adequate PO intake; direct PO absorption results in rapid increase of blood glucose concentrations.

Serves to restore blood glucose levels. Each 100 mL of 5% dextrose contains 5 g of dextrose while each 100 mL of 10% dextrose contains 10 g of dextrose.

Effective in small doses; no evidence indicates that it may cause toxicity; concentrated infusions provide higher amounts of glucose and increased caloric intake with minimum fluid volume.
