Do I need to eat before getting an IV?

Autumn and winter are common seasons for colds. Many people go to the hospital for intravenous drips because of a cold, but soon after the drip, they begin to feel dizzy, sweating, nausea and vomiting. After a check-up in the hospital, they find that this is basically caused by the drip on an empty stomach. So people begin to pay more attention to the issue of whether they need to eat before the drip.

When fasting, the body is in a state of weak metabolism. External stimuli (such as intravenous puncture on the back of the hand) make the body "wake up", followed by a series of physiological reactions, such as increased adrenaline secretion, faster heart rate, higher blood pressure, and increased body sensitivity.

If the fasting time is too long, the resulting hypoglycemia will further cause sympathetic nerve excitement and increased adrenaline secretion, aggravating the above symptoms.

In addition to its own adverse reactions, fasting infusion may sometimes induce adverse drug reactions or aggravate existing adverse drug reaction symptoms. Therefore, the elderly and infirm, especially those suffering from diabetes, coronary heart disease, hypertension, and stroke, must not forget to eat something before infusion.

definition

Infusion solution is a large dose (more than 100 ml at a time) of injection solution that is introduced into the body by intravenous drip. Usually packaged in glass or plastic infusion bottles or bags, without preservatives or antibacterial agents. When in use, the drip rate is adjusted through the infusion set to continuously and steadily enter the vein to replenish body fluids, electrolytes or provide nutrients. Because of its large dosage and the fact that it enters the blood directly, it has high quality requirements and its production process is also somewhat different from small-needle injections.

Classification

1. Electrolyte infusion is used to replenish the body's water and electrolytes, correct the body's acid-base balance, etc. Such as sodium chloride injection, compound sodium chloride injection, sodium lactate injection, etc.

2. Nutritional infusion is used for patients who cannot absorb nutrition orally. Nutritional infusions include carbohydrate infusion, amino acid infusion, fat emulsion infusion, etc. The most commonly used carbohydrate infusion is glucose injection.

3.Colloid infusion is used to regulate the osmotic pressure in the body. Colloidal infusions include polysaccharides, gelatins, and high molecular polymers, such as dextran, starch derivatives, gelatin, and polyvinyl pyrrolidone (PVP).
