4. Contraindication
• Sites close to infection .
• Veins of fractured limbs .
• Where there is an AV fistula present .

• Side of Mastectom
Extra care to be taken on patients with bleeding, clotting disorders & on

6. Site Of Vein Selection
• Where:
- Back of hand
- Forearm
- Antecubital fossa
• What:
- Patent - Palpable
- Distal - Straight
- Avoid bifurcations

7. Areas To Be Avoided
• Areas of joint flexion
• Hardened / sclerosed veins
• Major veins near arteries
• Veins in lower extremities
• Areas of surgery
• Small veins
• Previously cannulated veins

8. Location Of Veins
In Arm & Forearm
Veins of the Hand
1. Digital Dorsal veins
2. Dorsal Metacarpal veins
3. Dorsal venous network
4. Cephalic vein
5. Basilic vein
Veins of the Forearm
1. Cephalic vein

16. Procedure

17. Explain procedure to the patient.
Wear personal protection equipment's, i.e. gloves, apron (if required)
Select the location according to the procedure
Apply tourniquet
Make the selected vein prominent & clean the area with betadine solution.
Clean the area with alcohol swab
Stretch the skin and fix the vein
Insert the cannula at 45 degree to the vein.
Once cannula is inserted check the patency by using an IV flush.
Fix the cannula by using butterfly sticking.
Dispose the biological and plastic waste

20. New Methods
• AccuVein’s Illumination is the new infra-red device used
for venepuncture in the patients with difficult venous access
that include Elderly, Dark-skinned and Obese individuals.

21. Complications
• Hematoma
• Haemorrhage
• Infection
• Phlebitis
• Thrombophlebitis

23. Ampule

24. Preparing Medication From Ampule
• Lightly tap the top of the ampule with finger until fluid moves down from
the neck of the ampule.
• Rub the ampule filter on the neck of the ampule.
• Place swab around the neck of the ampule.
• Snap the neck of the ampule quickly & firmly.
• Insert the needle attached to the syringe into the centre of the ampule
opening . Do not allow the needle tip or shaft to touch the rim of the
ampule.
• Liquid fill into syringe by gently pulling back & tilting the ampule .
• Put empty ampule in kidney tray.

25. • Expel the excess air bubbles , remove needle from the ampule , hold
syringe with tip of barrel upwards , tap the side of the syringe to raise
the bubbles towards the tip of the barrel .
• Draw up slightly on the plunger & then push the plunger upward to
eject air.
• Attach the covered needle to the syringe & put it in the tray.

26. Vial

27. Preparing Medication From Vial
• Remove the cap covering of the vial to expose sterile rubber seal
, keeping the rubber seal sterile
• Hold the syringe & remove the needle cap.
• Pull back the plunger to draw the amount of air into the syringe
equivalent to volume of medication to be aspirated from the vial.

28. • Insert tip of the needle with bevelled tip entering through centre
of the rubber seal.
• Apply pressure to tip of the needle during insertion.
• Inject air into the vial’s air space.
• Invert vial while keeping firm hold on barrel & plunger.
• Fill syringe with the required medication & put the empty vial in
the kidney tray.
• Follow same expelling air step as ampule & needle capping step.
