LIGNOROS-AD INJ 30ML
LIGNOCAINE + ADRENELIN INJ
LIGNOROS-AD INJ 30ML is a 30 ml vial of lignocaine with adrenaline injection, a local anaesthetic combined with a vasoconstrictor. It is used for infiltration anaesthesia and nerve block in minor surgery and dental procedures, where the adrenaline prolongs the block and reduces bleeding at the site.
01
Benefits
- Adrenaline constricts local blood vessels, slowing absorption of the lignocaine and roughly doubling the duration of anaesthesia.
- Slower absorption also lowers peak blood levels, allowing a larger safe dose than plain lignocaine.
- Vasoconstriction reduces bleeding into the operative field, which improves visibility in minor surgery and dentistry.
- The longer block avoids the need for repeat injection during a longer procedure.
- The multi-dose vial suits dental surgeries and minor procedure rooms.

Side effects
Not everyone gets these. Most are mild and settle as the course finishes.

Stop and get medical help if any of these occur

- Persistent pallor, coldness or blackening of a digit or the tissue around the injection site
03
Precautions
- Never use adrenaline-containing local anaesthetic in the fingers, toes, nose, ears or penis. Vasoconstriction in an end-artery territory can cause tissue necrosis.
- For administration by a qualified healthcare professional, with resuscitation equipment and lipid emulsion available.
- Always aspirate before injecting; inadvertent intravascular injection of adrenaline can cause severe hypertension and arrhythmia.
- Use with caution or avoid in ischaemic heart disease, uncontrolled hypertension, significant arrhythmia and hyperthyroidism.
- Use with caution in patients on tricyclic antidepressants, monoamine oxidase inhibitors or non-selective beta-blockers, where the adrenaline effect is exaggerated.
- Contraindicated in known hypersensitivity to amide local anaesthetics, and in complete heart block.
- Observe the maximum dose by body weight, and warn the patient not to eat or handle hot objects until sensation returns.
- Multi-dose vial: strict aseptic technique at every withdrawal; discard after the stated in-use period.
