Placebo-controlled randomized double-blind comparison of the analgesic efficacy of lidocaine spray and etofenamate spray in pain control of rib fractures.

Background: As far as we could detect, we could not find any study in literature on the analgesic efficacy of spray forms of lidocaine and etofenamate in rib fractures. In this study, our aim is to empirically compare the analgesic efficacy of etofenamate spray, lidocaine 10% spray and placebo spray in the management of pain secondary to trauma secondary to isolated rib fractures.

Methods: The study was designed according to a single-center, prospective, randomized, placebo-controlled double-blind study model. About 30 sealed envelopes were prepared for each of the 3 groups and 30 patients were included in each group. A total of 84 cases were included in the study (three groups: 27, 28, 29).

Results: Numeric rating scale (NRS) grades at admission and at 15-30-60-120 min were similar between the three groups (P>0.05). Analysis findings of NRS perception differences between the initial NRS level and the 15-30-60-120th min NRS difference at the 0-120th min showed more lidocaine spray organs, and it was not clearly perceived that these four parameters went between the 3 groups for the outline.

Conclusion: The analgesic efficacy of lidocaine 10% spray, etofenamate spray, and placebo spray used together with standard dexketoprofen 50 mg intravenous treatment in the pain management of rib fractures were similar to each other and although there was a difference at the 120th min, this difference was not statistically significant.
