According to some data from the literature, it would seem that oxycodone and tramadol are equivalent in terms of analgesia. We have tried to prove that oxycodone (Oxynorm® instant) is not less effective than tramadol (Tradonal® odis) in an emergency unit. This is a prospective, monocentric, randomized study carried out amongst ambulatory patients. Those included in the study were given 1 g of paracetamol and a weight-ajusted dose of either tramadol or oxycodone. Every 30 minutes, a simple numerical scale (NS) was established and the clinical parameters were checked. We studied a total of 121 patients divided into 2 groups. There is an average difference of -1.47 between the average ?NS of the oxycodone group and the average ?NS of the tramadol group, with a confidence interval of 95 % (-9.42 – 6.48). The confidence interval does not cross the -10 line considered as the acceptable loss of efficiency, which allows us to conclude that oxycodone is not inferior to tramadol. As far as the adverse effects studied are concerned, there is no significant link between the treatment and the appearance of any side effect.
