Intravenous Fluid Type - NS, RL, DNS, D5

Intravenous Fluid 


The intravenous (IV) is the fastest way to deliver fluid replacement throughout the body as they are introduced directly into the circulatory system and thus quickly distributed.

 

Intravenous fluid drip used to administer electrolytes to correct electrolytes imbalance administered directly into the venous circulation.


The Intravenous (IV) route of administration is commonly used for rehydration or to provide nutrition for those who are unable to consume food or water by mouth. It helps restore salt and electrolyte levels in the body.

 

Classification of Intravenous Fluid/Solution

 

Intravenous solutions are classified into two types:


1. Crystalloids solution

2. Colloids solution: plasma expander

 

1. Crystalloids Solution


Crystalloid is a solution in which crystals may form but are able to diffuse across cellular membrane.


Example of crystalloids solution:


a. Normal saline

b. Ringer lactate

c. Dextrose5%

 

2. Colloids Solution


Colloids are a glue-like substance, such as protein or starch or a substance used as plasma expander in place of blood.


Example of Colloids solution:


a. Dextran

b. Albumin

c. Hetastarch

 

Types of Intravenous Solution


Intravenous solutions are three types:


1. Hypertonic solutions: water will move from extracellular space into cells. The result, Cell to expand size and burst.


2. Isotonic solutions: no movement of water between them. Cell neither swells nor shrinks.


3. Hypertonic solutions: movement of water from cells into extracellular space. The result, Cell shrinks.

 

Osmolarity of Body: 285-295 mosm/kg

 

 

 

Fluids Given Intravenously- IV Fluid (Bottles)


Intravenous fluids are given through a drip into the direct to a vein. It is used to correct electrolyte or acid-base balance in the body. These are:


1. NS- Normal saline water

NS 0.9% :0.9g Nacl in each 100ml of NS


Uses:


a. Used in dehydration

b. Used for wound washing

c. Used to given injection

d. Used in an accident and in Diabetic patient

 

2. RL- Ringer Lactate Solution, Hartmann’s Solution, Ringer Solution,  Sodium Lactate Solution

Ringer lactate solution consists of:


1. Sodium lactate

2. Nacl - sodium chloride

3. Kcl - potassium chloride and

4. Cacl2 - calcium chloride present in RL.

 

Uses:


a. Used in Diarrhea

b. Used in dehydration

 c. Used in burn, accident

 d. Used in dizziness, hypotension

 

3. DNS- Dextrose Sodium Chloride Solution (D – Dextrose: Glucose)

5g Dextrose in each 100ml of NS


Uses:


a. Used in Dehydration

b. Used in Hypoglycemia

c. Used in insulin shock


Caution: It is not used in Diabetic Patients


Types of DNS solution - D5, D10, D25, D50, D5NS, D5LR,

 

4. Mannitol Solution (Osmotic Diuretic)

20 gm mannitol in 100ml of solution


Uses:


a. Used in Diuretics

b. Used in Oligourea

 c. Used in Oedema

 d. Used in intraocular pressure


IV Fluid


Intravenous bottles



Every healthcare profession need to how at which angle of injection intravenously is given.
