Nursing Practical Guideline Procedure : Intravenous fluid

The introduction of large amount of fluid into body via veins is termed as I.V. infusions.

Intravenous fluid :


The introduction of large amount of fluid into body via veins is termed as I.V. infusions.


It has the following purpose :


1.     To restore the fluid volume that is lost from the body due to hemorrhage, vomiting, diarrhoea, drainage etc.


2.     To meet the patient's basic requirements for calories, water, minerals and vitamins.


3.     To prevent and treat shock and collapse.


4.     To supply the body with adequate amounts of fluids, electrolytes, and other nutrients when the patient is unable to take in adequate amounts by mouth or oral intake is contraindicated or impracticable.


5.     To administer medicines.


Indications of intravenous infusions:


Intravenous  infusions are indicated in the following situations :


1.     To save the patients in life threatening situations e.g., patients having hemorrhage, shock, extensive burns etc.

2.     To supply fluids and nutrients to the patients who may have nothing by mouth or who are unable to ingest oral liquids to prolonged nausea, vomiting, diarrhoea, peritonitis, paralytic ileus, fistulas etc.

3.     Supply fluids and nutrients to the patients who are unable to digest or absorb a diet administered by mouth or through the nasal tube; e.g., patients who do not have an anatomically intact intestinal tract or the patients with septicaemia etc

4.     To dilute toxins in case of toxaemia or septcaemia.


5.     To administer medications that are destroyed by the gastric juices or that will not be absorbed by the gastro-intestinal tract, if administered orally.


Solutions used:


1.     Nutrient solutions e.g.. dextrose 5%, 10%. 20%, 25%. 50%. etc.


2.     Electrolyte solutions available in isotonic, hypotonic and hypertonic concentration, e.g., normal saline, dextrose saline, lactated ringer's solution. 1/6 molar sodium lactate solutions etc.


3.     Alkalinizing and acidifying solutions, e.g.. sodium lactate solution, sodium bicarbonate, potassium chloride etc.


4.     Blood volume expanders. These are plasma substitutes and contain large molecular substances which will not escape through the vessel walls and tend to prevent the circulating fluid from leaking into the tissues, e.g.. dextran, lomodex. haemocoele etc.

Venipuncture sites:


a.     When selecting a site for administration of I.V. fluids, it is essential to consider the following factors :


2.     The condition of veins (collapsed or too small).


3.     The characteristics of tissues over the vein (oedematous, injured, diseased, inflammed etc.)


4.     Purpose and the duration of infusions.


5.     The type and the amount of I.V fluid ordered.


6.     The diagnosis and the general conditions of the patient.


7.     The most convenient veins for venipuncture in the adult are the basilic and the median cubital vein in the antecubital fossa because these veins are large and superficial. However, for prolonged infusions, these veins cannot be used without limiting the movements at the elbow joints by the use of splints.


8.     If the person is right handed, use of the left arm allows more independence and vice versa.


9.     The most commonly used veins in the order of their frequency of use are as follows:

a.     Veins of the forearm (basilic and cephalic veins).


b.     Veins in the antecubital fossa (median cubital, cephalic and basilic vein).


c.      Veins in the radial area (radial vein).


d.     Veins in the hand (dorsal metacarpel veins).


e.      Veins in the foot.


f.       Veins in the thigh (femoral and saphenous veins)


g.     Veins in the scalp (for infants).


Nurse's responsibility in the administration


a)     Check the patients' name, bed number and other identifications


b)    Check the diagnosis and the age of the patient.


c)     Check the purpose of infusion.


d)    Check the physician's orders for the type of infusion fluid, the strength, the amount and the duration of infusion.


e)     Check the consciousness of the patient and his ability to follow the instructions.

f)      Check the general condition of the patient, whether overhydrated or dehydrated.


g)     Check the site of infusion - note the condition of the veins and tissue at the infusion site.

h)    Check the abilities and limitations of the patient.


i)       Check the need for additional restraints.


j)       Check the patient's previous experience with infusions.


k)    Check the articles available in the patient's unit.


l)       Check the articles for their working order, the sterility of drip sets and the fluid. Check the expiry date of the fluid. Check the fluid fix discolouration, suspended particles etc.

28.                        When the prescribed volume of fluid has been infused, it is discontinued. To discontinue it :

a.     Clamp the infusion tubing. Loosen all the adhesive tapes that have been used to fix the needle and the


29.                        Withdraw the needle by pulling on the needle hub in line with the vein. At the same time hold a dry sterile swab over the needle site.

30.      When the needle is out, apply firm pressure to the site for 2 or 3 minutes, to prevent bleeding


31.      Apply a small sterile dressing over the needle site, which can be removed on the following day.


32.      Discard the bottle and tubing as desired.


33.      Record the total amount of fluid infused, the amount of fluid discarded if any, and the time at which the infusion is stopped.


34.      Watch for the general condition of the patient after the fluids have been discontinued. If the condition deteriorates, inform the doctor and restart the infusion.


Subcutaneous infusions (hypodermoclysis)


In medical practice, the term subcutaneous infusion or hypodermoclysis is used to designate an injection of a large amount of fluid into the subcutaneous tissues, by means of a needle for the purpose of supplying the body with fluids.


In this method, the fluid is absorbed principally by the lymphatics. It is given in a part where the tissue is loose. The purpose of subcutaneous infusions are same as that of intravenous infusions. This route is seldom used now-a-days due to increased facilities available for the intravenous infusions.


However, this route may be useful under emergency conditions. The Sites used for subcutaneous infusions are:


1.     Anterior and outer aspect of the thigh, midway between the knee and the hip.


2.     Under and outer margins of the breast.


3.     Abdominal wall halfway between the umbilicus and the flank.


4.     Back, just below the scapula.


5.     The equipment used for the subcutaneous infusion is same which is used for intravenous infusions.


6.     The subcutaneous infusions may be given in two places, using a T- connection to help in the maximum absorption of the fluid.

7.     To start the subcutaneous infusions, pick up a fold of subcutaneous tissue with the left hand and with the right hand insert the needle at an angle into the subcutaneous tissue in the direction of venous blood flow.


8.     The rate of flow is determined by the individual's rate of absorption.


9.     In all cases, the rate at which the fluid is given, should be such that the tissue around the needle stay nearly normal in tension and appearance.


10.                        Hyaluronidase injected into the tissues at the site of infusion or added to the infusion fluid, will increase absorption.


11.                        When swelling occurs, the infusion should be stopped completely.


12.                        The solutions used for the subcutaneous infusion should be isotonic.


13.                        Sugar solutions that are electrolyte free are contraindicated, as it may produce oedema at the injection site.


14.                        Hypertonic solutions are not absorbed. On the contrary, they may attract body fluids into the injection site.
