Dextrose blood pressure

Monitor electrocardiogram continuously in patients with cardiac abnormalities until serum potassium levels drop below 5 mEq/L (5 mmol/L) or cardiac abnormalities resolve. Evaluate serum potassium and glucose levels within 1 hour in patients who receive insulin and dextrose therapy. Evaluate serum potassium levels within 2 to 4 hours after treatment with SPS or diuretics. Repeat doses of diuretics or SPS if necessary until serum potassium levels fall below 5 mEq/L (5 mmol/L). Monitor blood pressure and serum potassium levels in 1 week in patients who receive fludrocortisone. 

Fluid replacement often is required and can be accomplished with IV dextrose 5% in normal saline solution at a rate to support blood pressure. 

Because patient tolerance varies greatly, a test dose may be preferred 1 mg in 20 ml of 5% Dextrose delivered IV over 20 to 30 minutes. Record patient s temperature, pulse, respiration, and blood pressure every 30 minutes for 2 to 4 hours. 

A 48-year-old hypertensive physician, who had optimal blood pressure control after taking oral amlodipine 5 mg/day for 3 months, developed a slight frontal headache and fever, thought that he had malaria, and took four tablets of chloroquine sulfate (total 600 mg base). Two hours later he became nauseated and dizzy and collapsed his systolic blood pressure was 80 mmHg and his diastolic pressure was unrecordable, suggesting vasovagal syncope, which was corrected by dextrose-sahne infusion. 

The effect of baricity on the hemodynamic effects of intrathecal 0.5% bupivacaine has been measured by recording invasive systolic blood pressure and central venous pressure in 36 men given plain bupivacaine 0.5%, heavy bupivacaine 0.5% (in dextrose 8%), or a mixture of the two (in dextrose 4%) (186). Heavy bupivacaine caused more rapid falls in central venous pressure and systolic blood pressure than plain bupivacaine. However, it was subsequently remarked that both 4 and 8% dextrose are significantly hyperbaric relative to adult cerebrospinal fluid, implying that the 4% solution should have behaved more like the 8% solution (187). 

An insulin infusion should be considered for severe cases of calcium channel blocker toxicity." Case reports suggest that an intravenous bolus of regular insulin (0.5-1 units/kg) with 50 mL dextrose 50% (0.25 mg/kg for children) followed with a continuous infusion of regular insulin (0.5-1 units/kg per hour) may improve myocardial contractility. The effect of insulin is presently unclear, but it may improve myocardial metabolism that is adversely affected by calcium channel blocker overdoses, such as decreased cellular uptake of glucose and free fatty acids and a shift from fatty acid oxidation to carbohydrate metabolism. This insulin regimen is titrated to improvement in systolic blood pressure over 100 mm Hg and heart rate... 

For hypotension in adults, administer norepinephrine, 32 mcg/min (use 8 mg in 500 mL dextrose 5%) with the rate adjusted to maintain low-normal blood pressure. Alternatively, administer dopamine at 2-10 mcg/kg/min intravenously.

Continuous infusion. Dilute 250 U of regular human insulin in 250 ml 0.9% saline. Follow bolus with 0.5-1 U/kg/h insulin infusion titrated above 100 as needed to increase blood pressure. Begin 10% dextrose infusion (at a rate of 1 g/kg/h) simultaneously to maintain glucose mg/dL. 

In another case, an elderly man treated with quinapril 20 mg daily for essential hypertension was found to have hyperkalaemia (serum potassium 7 to 7.4 mmol/L) and azotaemia after 20 days of treatment with co-tri-moxazole for mild acute pyelonephritis. Co-trimoxazole and quinapril were stopped, and nifedipine was given to control blood pressure. After treatment with dextrose, insulin, sodium polystyrene sulfonate and calcium gluconate, the azotaemia and hyperkalaemia resolved over 36 hours. ... 

A 26-year-old woman with a fever (38.9 °C) was given an intravenous infusion of Reduning injection 20 ml in 250 ml of 0.9% saUne and after about 20 minutes developed gum itchiness, lip numbness, chest distress, and red papules on the neck and face her blood pressure was 90/60 mmHg. The infusion was stopped immediately and she was given intravenous dexamethasone 10 mg and calcium gluconate 20 ml in 50% dextrose. The symptoms disappeared within 1 hour. 

A 62-year-old man was given Xing nao jing injection 30 ml in 5% dextrose 250 mL About 10 minutes into the infusion, he developed chest distension, shortness of breath, a flushed complexion, a tachycardia, and a raised blood pressure. The infusion was stopped immediately. After receiving oxygen, dexamethasone, and promethazine he made an uneventful recovery. 

The energy substrates are contraindicated in patients with hypersensitivity to any component of the solution. Dextrose solutions are contraindicated in patients with diabetic coma with excessively high blood sugar. Concentrated dextrose solutions are contraindicated in patients with increased intracranial pressure, delirium tremens (if patient is dehydrated), hepatic coma, or glucose-galactose malabsorption syndrome Alcohol dextrose solutions are contraindicated in patients with epilepsy, urinary tract infections, alcoholism, and diabetic coma... 

It is important that injectable solutions that are to be given intravenously are isotonic, or nearly so. Because of osmotic pressure changes and the resultant exchange of ionic species across red blood cell membranes, nonisotonic solutions, particularly if given in quantities larger than 100 mL, can cause hemolysis or cre-nation of red blood cells (owing to hypotonic or hypertonic solutions, respectively). Dextrose, sodium chloride, or potassium chloride is commonly used to achieve isotonicity in a parenteral formula. 

IV) solutions into an individual. Normally, any fluids infused intravenously must have the correct osmolarity they must be isotonic with the blood cells and the blood plasma. Such infusions are frequently either 5.5% dextrose (glucose) or "normal saline." The first solution is composed of 5.5 g of glucose per 100 mL of solution (0.30 M), and the latter of 9.0 g of NaCl per 100 mL of solution (0.15 M). In either case they have the same osmotic pressure and osmolarity as the plasma and blood cells and can therefore be safely administered without upsetting the osmotic balance between the blood and the blood cells.
