This document provides information about a tuberculin syringe, Mantoux test procedure, BCG vaccination, and a scalp vein needle. It describes the uses of a tuberculin syringe as administering the PPD for Mantoux testing, BCG vaccine, test doses of drugs, and insulin injections. It outlines the procedure for Mantoux testing, including interpretation of induration size and appropriate actions. Details are given on BCG vaccination dosage, administration route, effects, and adverse reactions. Finally, it describes the components and uses of a scalp vein needle for blood collection, intravenous infusions and fluids, and arterial blood gas analysis.

1. TUBERCULIN SYRINGE
It is 1cc syringe with a plastic piston (plastic
syringe), or a metal piston ( glass syringe)

3. USES :
• To administer PPD for Mantoux test.
• To administer BCG vaccine.
• To adminiter test doses of drugs such as
penicillin.
• Provocative Testing – to test for allergens in
Bronchial asthma , atopy.
• Insulin injections in Diabetes Mellitus.
• Giving small doses of drugs. Eg. Gentamicin,
Phenobarbitone , Digoxin.

4. MANTOUX TEST
Tuberculin PPD 2 T.U./0.1 ml, solution for
injection:
1 dose = 0.1 ml contains 0.04 microgram
Tuberculin PPD.
– Store at 2°C - 8°C, protected from light

5. PROCEDURE OF MANTOUX TEST

6. Diameter of induration Interpretation Action
Less than 6mm Negative Previously unvaccinated
individuals may be given
BCG provided there are no
contraindications.
6mm or greater but less Hypersensitive to tuberculin Should not be given BCG
than 15mm protein. May be due to
previous TB infection, BCG
or
exposure to atypical
mycobacteria
>= 15mm Strongly hypersensitive to Should not be given BCG.
tuberculin protein Refer for further
Suggestive of TB infection investigation
or and supervision which may
disease include chemotherapy.

7. BCG Vaccination
• It induces primarily cell mediated immunity.
• Administered at or soon after birth
• Supplied in the form of lypophilised or freeze
dried powder, in a vaccum sealed dark colored
multidose vial.
Reconstituted with normal saline.
• Extremely sensitive to light and heat. Thus,
cold chain should be maintained.
• In lypophilised form, it remains potent for
upto a year at 2-8 ˚C.

8. • Dose – 0.1ml
• Site- convex aspect of left shoulder at the insertion
of deltoid to allow for easy identification of scar.
• Route of administration – intradermal
• Multiplication of BCG bacilli papule at 2-3
weeks 4-8 mm in size at 5-6 weeks
ulceration heals by scarring around 6-12
weeks
• Adverse effects – persistent ulcer with delayed
healing ipsilateral axillary or cervical
lymphadenopathy, and rarely abscess and sinus
formation.
• Positive reaction to tuberculin test 4-12 weeks
after immunisation.

9. SCALP VEIN NEEDLE
• It consists of a metallic needle attached to a plastic tubing.
• At the junction of the needle and the tubing, there is butterfly
shaped plastic holder which facilitates easy insertion of the
scalp needle into the vein.
• The plastic holder is flexible and colour coded .eg . Black is no
22.
• The commonly used needles are from no 22 to no 24.
• There is an inverse relation between the guage number and
the internal diameter.
• Higher the guage number , small is the diameter of needle.
Thus 24G needle is smaller in diameter than 22G needle.

11. USES
• Collection of blood
• Infusion of iv fluids, drugs, blood etc.
• ABG analysis
