1. The document discusses the procedure for intravenous catheterization and taping. It describes selecting an appropriate catheter, preparing the skin, inserting the catheter into a vein, securing it, and caring for the catheter site. 2. Key steps in the procedure include shaving and disinfecting the skin, inserting the needle at a 30-40 degree angle to access the vein, securing the catheter with tape to prevent dislodgement, and flushing it with saline to maintain patency. 3. The catheter should be secured carefully and the site inspected regularly for signs of phlebitis. Peripheral catheters should be resited every 48-72 hours to reduce risks of infection and phlebit

2. Intravenous cannulation is a technique in which a cannula is
placed inside a vein to provide venous access
Introduction :
Venous valves
encourage
unidirectional flow of
blood and prevent
pooling of blood in the
dependent portions of
the extremities; they
also can impede the
passage of a catheter
through and into a
vein
Venous valves
are more
numerous just
distal to the
points were
tributaries join
larger veins and
in the lower
extremities

3. INDICATIONS:
Repeated blood sampling
Intravenous fluid administration
Intravenous medication administration
Intravenous chemotherapy administration
Intravenous nutritional support
Intravenous blood or blood products administration
Intravenous administration of radiological contrast agents
(eg, computed tomography, magnetic resonance imaging,
nuclear imaging)

4. CATHETER SELECTION
COLOR SIZE (guage) mm Max. flow / min (length)
Orange 14 2.0 265 ml/min (1=44mm)
Grey 16 1.7 170 ml/min (1=42mm)
Green 18 1.2 90 ml/min (1=40mm)
Pink 20 1.0 55 ml/min (1=32mm)
Blue 22 0.8 25 ml/min (1=25mm)
Yellow 24 0.6 20 ml/min (1=20mm)
Silicon and polyurethane are minimally reactive, making these materials ideal for use in long-term catheters

5. EQUIPMENT REQUIRED:
I.V Canula (according to b.wt)
I.V Canula Fixator / Alcohol
Wipe / Sterile Gauge Pieces
Thin strips of Adhesive
tape (for securing further)
Tourniquet / Shaving Blades
/ Shaving Razor / Savlon
10-12 ml syringe filled
saline / heparinized saline

6. STEP WISE
PROCEDURE

7. CATHETERIZATION TECHNIQUE
Step-I
The catheter placement site should be widely shaved and
the skin scrubbed with antiseptic solutions

8. STEP-II
Apply a tourniquet / thumb dorsal to the most proximal
aspect of the limb to restrict blood flow returning from
the distal limb --- > vein engorge

9. STEP-III
cleanse skin / disinfect
the skin area with
alcohol wipe

10. STEP-IV
Place cannula needle in
line with direction of
the vein at an angle of
30-40 degree, and a
few mm below proposed
entry site, with bevel
pointing upwards

11. STEP-V
Advance the catheter
into the place where you
visualized or palpated
the vein
Once you receive blood
back into the hub of the
catheter, slowly feed
the catheter off the
stylet and into the vein

12. STEP-VI
Withdraw the needle stylet (holding the
cannula steady) about 5mm to avoid
piercing the posterior vein wall, there
should be a further flashback of blood
along the shaft of the cannula and now
advance the cannula into the vein

13. STEP-VII
Catheter in place. Attach the fluid line
immediately after removing the stylet and
driven the i.v cannula fixator underneath
the fluid line over the catheter hub

14. STEP—VIII
Proper fixing of the cannula fixator with
the help of adhesive tape in a double row
i.e just cranial and caudal to injectionport
cap

15. STEP-IX
After proper taping, the
fluid administration set is
looped and taped to the
leg
This reduces the chance of
accidental removal of the
catheter if the
administration set is pulled

16. STEP-X
After completion, flush the cannula with
heparinised saline to ensure cannula
patency and after this, attach the
“luer lock plug” to prevent the blood
outflow

17. STEP-XI
Cover the
insertion
site and
immobilise
the
cannula by
applying a
sterile
non-
occlusive
dressing

21. SECURING THE CANNULA
 It is important to secure the cannula to prevent
mechanical phlebitis. This can be done with
clean tape or a special adhesive dressing
 Care should be taken to avoid the insertion site. If
the device is located over a joint, the joint should be
immobilised and splinted to prevent movement and
dislodgement of the cannula

22. CARE OF THE CANNULA
 Once sited the cannula should be flushed with
either normal saline or heparinised saline. The
site should be regularly inspected for signs of
phlebitis
 Peripheral cannula should be re-sited every 48-
72 hours to reduce the risk of phlebitis, but this
may be difficult in patients with difficult veins

23.  Cannula should not remain in situ for any
longer than necessary to reduce the risks of
infection. Consideration should be given to
resiting them after 48-72 hours
 When removing the cannula, pressure should
be applied to the site for at least a minute and
the site should be occluded with a sterile
dressing
