BET 2: Usefulness of IV lidocaine in the treatment of renal colic.

A shortcut review was carried out to establish whether intravenous lidocaine is effective in the management of renal colic. Two studies were directly relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these studies are tabulated. The clinical bottom line is that intravenous lidocaine may be of some benefit in renal colic. However, there are other maybe more effective drugs available.
