A comparison of alcoholic and aqueous formulations of local anaesthetic as a spray for the relief of post-episiotomy pain.

A comparison of pain relief after a single perineal application of alcoholic and aqueous formulations of lignocaine (5%) spray with an aqueous formulation of cinchocaine (2%) spray was made in 72 primiparous patients complaining of moderate or severe post-episiotomy pain. All three formulations were similar in efficacy, the aqueous lignocaine preparation appearing slightly more effective than the others.
