Hypoglycemia is common in elderly acute critical care medicine is one of acceptance of insulin and oral sulfonylureas in the treatment of diabetes is especially common. In severe cases, cause death is often impossible to save her. The duration of low blood sugar is too long, even if the life saved may also leave irreversible damage to brain tissue. Therefore, timely diagnosis and prompt and effective rescue severe hypoglycemia, related to the patient’s life, and prognosis.
Often have family members asked why hypoglycemia occurs, similar to such a serious low blood sugar coma more common in elderly patients with unstable diabetes or newly diagnosed diabetes.
Since start using hypoglycemic drugs, drugs are not familiar with the characteristics and maintenance of time, drug dosage and blood glucose, eating the relationship between the law not to work out, are particularly vulnerable to hypoglycemia coma, convulsions. Also, because coma, convulsions symptoms, needs and cerebrovascular disease, intracranial infections, epilepsy, mental illness and other diseases, phase identification, short-term diagnosis is often difficult. Then, if there is no time to consider hypoglycemia, it is easy to save time delay, leading to serious consequences. Therefore, authors believe that a coma patient should be routine testing blood sugar, for the timely rescue of patients with low blood sugar coma.
Rescue hypoglycemia should be quick to add high concentrations of glucose, quickly correcting the low blood sugar. General intravenous injection of 50% or 25% glucose solution 20 ~ 40ml, depending on condition can be used repeatedly until the patient turned clear consciousness, sweating stops, heart rate slowed up. Need to be reminded is the need for excessive insulin or oral sulfonylureas and acarbose combined due to low blood sugar, the consumption of starch and sugar are not promptly and effectively, because at this time intestinal α-glucosidase enzyme has been acarbose competition inhibition, but must be injected high concentrations of glucose, so as not to delay the time to save. Glucagon is also able to correct the low blood sugar, general use 1mg veins, muscles, subcutaneous injection can be. Intravenous injection of 1 minute onset, can be maintained for 30 minutes. Drug on insulin-induced hypoglycemia, effect of excessive particularly good, but the sulfonylureas and insulin-induced hypoglycemia tumor efficacy difference. Intravenous injection of 50% or 25% glucose solution very easy to suffer from high blood sugar, while glucagon is not accompanied by reversal of hypoglycemia, high blood sugar reaction, which is one of the advantages of the drug.
Low blood sugar in the rescue, while attention should be paid to prevent low blood sugar caused by secondary damage, especially to brain tissue damage. The latest study confirmed: some calcium antagonists, such as nimodipine reduce the insulin-induced hypoglycemia on brain injury, should be on time. Must also ensure that adequate oxygen supply and maintain adequate cerebral blood flow.
