Randomized Controlled Trial Clinical Trial[Usefulness of gel lidocaine in esophageal manometry].
Esophageal manometry (EM) is a functional study performed without sedation. The insertion of a catheter through nasal passages provokes the greatest discomfort as it is being performed. ⋯ Lidocaine jelly at 2% neither diminishes the discomfort provoked by the insertion of an EM catheter, nor does it make the procedure any easier.
