Intake of glucose by mouth The blood glucose can usually be raised to normal within minutes with 15–20 grams of carbohydrate, although overtreatment should be avoided if at all possible. It can be taken as food or drink if the person is conscious and able to swallow. This amount of carbohydrate is contained in about 3–4 ounces (100–120 mL) of orange, apple, or grape juice, about 4–5 ounces (120–150 mL) of regular (non-diet) soda, about one slice of bread, about 4 crackers, or about 1 serving of most starchy foods. Starch is quickly digested to glucose, but adding fat or protein retards digestion. Composition of the treatment should be considered, as fruit juice is typically higher in fructose which takes the body longer to metabolize than simple dextrose alone. Following treatment, symptoms should begin to improve within 5 to 10 minutes, although full recovery may take 10–20 minutes. Overtreatment does not speed recovery, and will simply produce hyperglycemia afterwards, which ultimately will need to be corrected. On the other hand, since the excess of insulin over the amount required to normalize blood sugar may continue to reduce blood sugar levels after treatment has produced an initial normalization, continued monitoring is required to determine if further treatment is necessary. Intravenous glucose If a person cannot receive oral glucose gel or tablets, such as the case with unconsciousness, seizures, or altered mental status, then emergency personnel (EMTs/Paramedics and in-hospital personnel) can establish a peripheral or central IV line and administer a solution containing dextrose and saline. These are normally referred to as Dextrose (Concentration) Water, and come in 5%, 10%, 25% and 50%. Dextrose 5% and 10% come in IV bag and syringe form, and are mainly used in infants and to provide a fluid medium for medications. Dextrose 25% and 50% are heavily necrotic due to their hyperosmolarity, and should only be given through a patent IV line – any infiltration can cause massive tissue necrosis. It is MUCH safer to use a Dextrose 10% solution when treating hypoglycemia via IV in children under the age of 14. When using Dextrose 25% in a child it is safer to administer it through a central line or an intra-osseous line. Glucagon Glucagon is a hormone that rapidly counters the metabolic effects of insulin in the liver, causing glycogenolysis and release of glucose into the blood. It can raise the glucose by 30–100 mg/dL within minutes in any form of hypoglycemia caused by insulin excess (including all types of<unk> . It comes in a glucagon emergency rescue kit which includes tiny vials containing 1 mg, which is a standard adult dose. The glucagon in the vial is a lyophilized pellet, which must be reconstituted with 1 mL of sterile water, included in the "kit". In the widely used Lilly Emergency Kit, the water is contained in a syringe with a large needle for intramuscular injection and must be injected into the vial with the pellet of glucagon before being injected. Glucagon works if given subcutaneously, but absorption and recovery are faster if it is injected deep into a muscle (usually the middle of the outside of the thigh). It has an even more rapid effect when given intravenously but this is rarely practicable. Side effects of glucagon can include nausea and headache, but these can also occur after severe hypoglycemia even when glucagon is not used. Risks of glucagon use are far lower than risks of severe hypoglycemia, and it can usually produce a faster recovery than calling for paramedics and waiting for them to start an intravenous line to give dextrose. If someone uses this kit, they should be seen in an emergency room, as glucagon depletes glycogen stores, and can lead to a deadly rebound hypoglycemia. In the United States, caregivers for patients with Type 1 diabetes are instructed to have an unexpired glucagon emergency kit on hand at all times. A number of companies are developing glucagon injection devices with the goal of simplifying administration for caregivers and patients during severe hypoglycemic events. For many, the current standard of care (the glucagon emergency kit) is burdensome and not caregiver or patient-friendly due to the multiple steps required to administer the drug, especially during an emergency situation. To improve hypoglycemia treatment, many companies are developing more efficient glucagon delivery solutions. Xeris Pharmaceuticals, Inc. is developing the Glucagon Rescue Pen or G-Pen using a patented non-aqueous formulation of glucagon that is room-temperature stable, low-volume, and pre-mixed in an auto-injectable device (similar to an EpiPen) that takes the injection process down to two steps (as opposed to nine steps with glucagon emergency kits currently on the market). Similarly, GlucaPen, an autoinjector in development by Enject, Inc. promises to simplify the delivery of glucagon.
