3. Types of Cannula
• IV Cannula Pen Type Model
• IV Cannula with Wings Model
• IV Cannula with Injection Part Model
• IV Cannula Y Type Model
• Scalp Vein Cannula
9. Why Veins are Suitable for Insertion
• Superficial
• Palpabe
• Visible
• Blood at Low Pressure
• Relatively Large internal Diameter
• Tough Vasuclar Wall - Able to form a seal
around the cannula
• Offer a Rapid Route - Circulatory system
10. Signs of Good Vein
1. Bouncy
2. Soft
3. Above Previous Vein
4. Refills when Depressed
5. Visible
6. Has a Large Lumen
7. Well Supported
8. Staright
9. Easily Palpable
11. Tips
No. Features Rational
1 Smallest size of catheter
2 EMR situation use a large
gauge catheter
3 Upper Extremities
4 Lower extremities
5 Peripheral venous access
interfere less with pt's
6 Recommended to choose a
straight portion of a vein
7 Use the patient's non-dominant
arm
8 For prolonged courses of
therapy it is recommended to
start distally & move
proximally as distal catheters
are replaced.
12. Tips
No. Features Rational
1 Smallest size of catheter To prevent damage to the vessel intima
2 EMR situation use a large
gauge catheter
To allow administration of large volumes
of fluid quickly
3 Upper Extremities The superficial veins
4 Lower extremities Peripheral venous access
5 Peripheral venous access
interfere less with pt's
Mobility & pose a lower risk for
phlebitis
6 Recommended to choose a
straight portion of a vein
To minimize the chance of hitting valves
7 Use the patient's non-dominant
arm
Convenience, Further damage is been
prevented
8 For prolonged courses of
therapy it is recommended to
start distally & move
proximally as distal catheters
are replaced.
Distal Damage - Proximal is available
for the further line
Proximal As first Line - Distal u cant
get the line for the therapy
13. Indications
• Repeated blood sampling
• IV fluids
• Medications
• Chemotherapy
• Nutritional Support
• Blood or Blood products administration
• Radiological contrast agents for CT, MRI or
nuclear imaging
23. Topical Anesthesia for IV Insertion
• Lidocaine
• Buffered lidocaine
• Bacteriostatic normal saline
24. Before The Procedure
• Introduce yourself to the patient.
• Explain the procedure to the patient & gain informed
consent to continue
• Make sure there is adequate light & that the room is
warm enough to encourage vasodilation
• Make sure the patient is in a comfortable position
• The patients skin should be kept clean for the procedure
33. IV Cannulation in Fragile Veins
• Say no to tourniquet as much as possible
• Use the smallest catheter as much as
possible - 20 to 22g
• Use Bevel Up, Low Angle & Slowly but
surey approach
• Secure the catherter with Micropore or
Transparent dressing
• Provide Health Education
34. IV Cannulation for the Geriatrics
• Extremely Challenging
• Avoid applying too much friction when
preparing the skin
• use the smallest catheter
• Know the veins depth
• If possible do not use tourniquet,
Incase use a soft material ones
• stabilise the vein & insert the
catheter on top of the vein
• Hypoallergic Tape tape to be used
35. Documentation
• Date & Time
• Site & Size of the Cannula
• Any Problems Encountered
• Notes Eaxmple:
• 22/8/19 @ 3pm: Inserted 16G Needle under
Clean Techique in a single prick in Rt
Metacarpel region by S/N XX,Pt cooperated,
Back Flow Present, Flushed with 5ml Poshi
flush or NS,Line Intact & Patent,Line
Secured with dynaplast & labelled with
date & time. Score: I 0/4 & P 0/5
36. • 22/8/19 @ 3pm:Inserted 20G Needle under Clean
Techique in Lt anaesthetist vein. First prick
failed since there was no back flow or
infiltration present in Lft Cephalic Vein by
S/N xyz.
• By 2nd prick line was secured by Anaesthetist
XXXX. Pt was irritable.
• Back Flow Present, Flushed with 5ml Poshi flush
or NS,Line Intact & Patent
• Line Secured with Tegaderm & labelled with date
& time.
• Score: I 0/4 & P 0/5
42. Purpose
To administer the appropriate amount of
fluid to the patient
To prevent fluid overload & fluid
deficiency
To prevent, treat & support the
patient’s condition with the help of
correct administration of fluid.
