Supply of Infusion Fluids – IV fluids an educational review

Transfusion of infusion fluids is one of the basic therapies used in the hospital. The nurse has their share because as a person performing a medical order, he not only performs intravenous punctures but also transfuses infusion fluids and keeps their balance and IV Supplies Solution.

Fluid infusion is carried out on patients who cannot take them by mouth, i.e. all those with swallowing disorders, the unconscious in whom accurate fluid balance is important, and all patients before and after surgery.

IV fluids:

IV fluids are liquids that are injected into a vein to prevent or cure dehydration. They are given to persons of all ages who are unwell, injured, dehydrated from activity or heat, or who are undergoing surgery. Intravenous rehydration is a straightforward, risk-free technique with little side effects.

What are the types of IV fluids?

Types of IV Fluids

IV fluids come in a variety of forms. Depending on why you need them, your healthcare professional will determine which type is best for you.

1. Crystalloid solutions:

These are the most prevalent IV fluid kinds. They contain small dissolved chemicals that easily move into tissues and cells from the bloodstream. Normal saline, which is salt in water, and D5W, which is dextrose (sugar) in water, are two examples.

Lactated Ringer’s is another example, as it contains salt, chloride, potassium, calcium, and lactate. It’s used to refill a lot of fluid quickly.

2. Colloids:

These are big molecules that have a difficult time passing through cell membranes and are therefore more likely to remain in blood vessels. Albumin hetastarch are two examples.

IV fluids for dehydration

Normal saline, 5 percent dextrose solutions dissolved in water, and Lactated Ringer’s solutions are all isotonic IV fluids. Dehydration induced by electrolyte imbalances, as well as fluid loss through diarrhea and vomiting, are treated with these.

Supply of infusion fluids an educational review:

The primary purpose of the infusion is hydration with supplements of micronutrients and vitamins. Thanks to this, the patient is provided with proper tissue perfusion and excretion of waste products.

Intravenous infusion is a procedure used in cases where fluids or diluted drugs must be applied to the vein in a calibrated, slow manner for hours or days.

Supply of Infusion Fluids kit

The human body needs 2 to 3 liters of fluid per day This demand may be greater in a situation of high temperature (body or environment) and intense physical effort. Dehydrated patients deserve special attention.

Dehydration can be caused by a number of factors such as diarrhea, vomiting, fever, burns and swallowing disorders, and consciousness. In addition, two groups of patients are at risk of dehydration: the elderly and children.

Symptoms of dehydration include apathy, consciousness disorders, oliguria, drying of mucous membranes and skin, tachycardia.

To control fluid supply, to avoid overhydration and dehydration, a fluid balance is maintained. It involves counting the intake and excretion of fluids.

Their sum should be similar as for drinking fluids, both drinking and food as well as infusion fluids are included. Fluids excreted include urine, stool, exhaled water vapor, and sweat.
The hourly requirement should be considered when choosing the infusion fluids and the amount to be transfused:

  •  1-10kg – 100ml / kg bw / 24h
  • 11-20- 50ml / kg / 24h > 20kg 20ml / kg bw 24h

Preoperative deficit (how long the patient has been drinking) and intra-operative (blood loss), fluid loss through drains, evaporation, fever.

Division of liquids (Infusion fluids):

Crystalloids are electrolyte solutions that easily diffuse through the capillary membranes. They are used to cover fluid losses and prevent water management disturbances.

Available fluids differ in the content of molecules such as Na, K, Mg, as well as os-molarity and pH. Among the disadvantages of crystalloids is their passage into the extra-vascular space which can cause swelling, poorer wound healing, and leaching of drugs.

These are intervention fluids, however, they should be supplemented with colloids for longer periods of treatment. The advantage of crystalloids is their availability and low price. They do not cause allergic reactions.

Colloids are multi-particulates, their task is to replace plasma and compensate for intravascular volume loss, increase cardiac ejection volume, also stabilize the circulatory system and improve oxygen transport.

We divide them into natural (albumin, fresh frozen plasma) and artificial (dextrans, gelatin).
Colloids create oncotic pressure, bind water molecules so that it does not get out of the vessel. However, they are more expensive and can cause allergic reactions.

The first 20 ml should be administered slowly because of the possibility of an anaphylactoid reaction.

The basic parameters that assess hydration are heart rate, pressure, diuresis. Too fast transfusions or too much fluid can lead to circulatory disorders and pulmonary edema.

Gravity infusion fluids:

The most common form of infusion fluids is gravity, it consists of a fluid and a transfusion set attached to it, which can regulate its flow over time (20 drops is 1 ml).

Plasma and albumin should be transfused using blood transfusion sets, they are additionally equipped with a filter. Pumps are another form of supply. Thanks to them, the fluid is dosed more precisely than by gravity.

The fluid temperature should be close to the patient’s body temperature of 36 C. When rolling large amounts of fluids at a low temperature, the patient may become cold and have associated complications.

The infusion supply related complications are the transfusion process itself, i.e. the use of the preparation after its expiration date, fluid contamination (the fluids are originally sterile), and intravenous administration.

General FAQs:

What are the requirement for fluid infusion?

25–30 ml/kg/d water is the normal daily fluid and electrolyte needs. sodium, potassium, and chloride 1 mmol/kg/day 50–100 g glucose per day (for example, glucose 5% comprises 5 g/100ml). When IV fluids are no longer required, they should be stopped. When maintenance is required for more than three days, nasogastric fluids or enteral feeds are preferred.

What supplies are needed for IV?

A tourniquet, antiseptic (to clean the patient’s skin before starting the IV), gauzes, tape, tegaderm, and a sticker to label the IV with your initials, date, time, and IV needle gauge are all included in the IV kit.

What IV fluid is best for dehydration?

Half-normal saline, which comprises 0.45 percent sodium chloride and 5% glucose, is the most frequent form of hypotonic IV fluid. Dehydration caused by hypernatremia, metabolic acidosis, and diabetic ketoacidosis are commonly treated with this type.
