what are the types of intravenous fluids and when are they used?

Answer 1

Please see the web pages for more details on Saline, Pentastarch, Lactated Ringer's solution and Intravenous therapy.
Three principles of fluid therapy:
(1) Replace fluid lost. In practice the problem is usually whether to give saline or dextrose. Most body fluids contain salt but less than plasma.
Features indicating that water (5% dextrose) is needed.
Thirst, Low urine output with high ratio of urine: plasma osmolarity, Dry axilla and groin, Raised plasma sodium.
Features indicating that saline is needed:
Fluid lost (excess diuretic, vomit, burns, diarrhoea, sweat), Decrease tissue tugor, Postural hypotension, Tachycardia, Low JVP, Low urine output, ratio of urine: plasma osmolarity around unity, Raised haematocrit.
Features indicating need for another fluid:
If acute blood loss give blood.
If patient 'shocked' a 'plasma expander' or 'colloid' is normally given.
(2) Allow for future abnormal loss. Moderate continuous sweating requires an extra 500 ml of 0.9% saline and 500 ml 5% dextrose per 24 h as does a fever above 39.5 degree C.
(3) Maintain normal daily requirements. About 2500 ml fluid containing 100 mmol sodium and 70 mmol potassium per 24 h are required. A good regimen is 2500 ml dextrose-saline with 30 mmol potassium per litre.
Postoperative patients usually need more fluid and more saline.
Patients with heart failure should not have saline. If fluids IV must be given use 5% dextrose and proceed cautiously.

An intravenous drip is the continuous infusion of fluids, with or without medications, through an IV access device. This may be to correct dehydration or an electrolyte imbalance, to deliver medications, or for blood transfusion. IV fluids There are two types of fluids that are used for intravenous drips: crystalloids and colloids. Crystalloids are aqueous solutions of mineral salts or other water-soluble molecules. Colloids contain larger insoluble molecules, such as gelatin; blood itself is a colloid. The most commonly used crystalloid fluid is normal saline, a solution of sodium chloride at 0.9% concentration, which is close to the concentration in the blood (isotonic). Ringer's lactate or Ringer's solution is another isotonic solution often used for large-volume fluid replacement. A solution of 5% dextrose in water, sometimes called D5W, is often used instead if the patient is at risk for having low blood sugar or high sodium. The choice of fluids may also depend on the chemical properties of the medications being given.

Types Of Iv Fluid

Answer 4

Long answers, easy questions.

The most common fluid in an IV is called 0/9% normal saline. This is as close as we can get to replicating the fluid which already exists in your body. Everyone who gets an IV gets this initially.

Another common one is called lactated ringer's. This contains more "stuff" that may be needed by your body. This is more useful for dehydration or other systemic illnesses.

There are several other less common types of fluids, including D5W (or variations thereof) and KCl. But again, these are all additives to the basic normal saline, as mentioned above.

Answer 5

there are so many intravenous fluids used for so many different reasons. That is why professionals go to school for years to learn, in part, about these things. Suggest if you want to know all that, you go to college yourself and learn. It would take a book's worth of writing to answer your question.

Answer 6

There are too many to name. Some are antibiotics, regular fluids a dehydrated person needs, some keep blood pressure down, some keep it up, some are for keeping the heart regular, some put you to sleep, some give you a little extra vitamins and on and on ......................
