Randomized Controlled TrialDelayed versus immediate urethral catheterization following instillation of local anaesthetic gel in men: a randomized, controlled clinical trial.
The product information for local anaesthetic (lignocaine) gel recommends a delay of 'several minutes' between gel instillation and urethral catheterization in men. However, pilot data indicate that approximately half of physicians omit this delay. We aimed to compare the discomfort of urethral catheterization performed immediately or after a 2 min delay following instillation of local anaesthetic gel. ⋯ A 2 min delay following instillation of local anaesthetic gel before urethral catheterization in men does not decrease the pain of the procedure.
