My review of Lidayn Lidocaine Topical Aerosol (Surface Anaesthetic)
Use of topical anaesthesia in the form of spray, gel or ointment to reduce pain and anxiety for patients before administration of local anaesthetic injection has been highly recommended. As is it’s use in extraction of deciduous and mobile tooth.
Topical local anaesthetics are available as Ligocaine or Benzoncaine. Studies have shown that Lignocaine has a faster onset of action with better efficacy in reducing pain.
Using a spray local anaesthetic instead of a gel gives you not much of an advantage, other than the cost factor. On the other hand, patient discomfort is greater with spray, as the spray tends to enter the throat inducing a gagging reaction. Even the taste of the spray is disliked by many patients.
To reduce the effect of spray, you may spray onto a pellet of cotton and then apply the cotton to the area of interest, rather than directly spraying the area. This though can reduce the efficacy of the anaesthetic agent.
A better alternative is use a local anaesthetic gel which has similar efficacy and does no discomfort to the patient.
So any reason that you want to use a spray LA? Just that it is a cost-effective topical anaesthesia.
In my opinion, as you are using a topical LA to provide patient comfort, LA gel should be a preferred option.
