Local Anaesthesia – Buffering Lignocaine

If you would like to make your patients more comfortable during surgical procedures, please watch the below short video with Dr Hamilton Ayres about buffering lignocaine. The experienced skin cancer doctor explains how you can buffer the local anaesthetic (i.e. raise the pH and alkalinise the solution) to make the injection less painful for your patient. This is especially useful for procedures on sensitive areas such as the nose tip or the toes.

For more information you can read the 2016 local anaesthetic guidelines here: http://www.jaad.org/article/S0190-9622(16)00074-8/fulltext#sec7.6

  1. Thanks!!
    How long is the sodium bicarb good for once you have opened it up and dated it????

    1. Thank you for your question, Dr. Johnston. On behalf of Dr. Hamilton Ayres: There is no firm guideline regarding how long the bicarb is good for once opened and dated. But given that the MIXTURE of bicarb with local anaesthetic is OK for up to one week (as per 2016 local anaesthetic guidelines which are readable here http://www.jaad.org/article/S0190-9622(16)00074-8/fulltext#sec7.6), 1 week should be reasonable.

      But there’s really no reason you can’t just make up the mixture of buffered LA for the day/week (maybe label and store it in a central fridge / local anaesthetic drawer in your treatment room) and then immediately throw away the half-used bicarb. That’s what Dr. Hamilton Ayres recommends. The 10mL vials only cost $5 (about $55 for 10 vials, including shipping, in Australia).
