Fig. 3. Prevention of succinylcholine-related fasciculation. For each intervention that was tested in at least three trials, a meta-analysis was performed (# = number of analyzed trials). Symbol sizes are proportional to the number of analyzed patients. CI = confidence interval; NNT = number needed to treat; NSAID = nonsteroidal antiinflammatory drug (aspirin, diclofenac, ketorolac); benzodiazepine (diazepam, midazolam); sodium channel blocker (lidocaine, phenytoin); RB = relative benefit.
