A Randomized Double-Blind Study; Evulation of Comparing Intravenous Fentanyl with Intravenous Tramadol Administered to Patients with Pain Control Due to Urinary Stone Disease

Aim
The aim of our study is to compare the efficiency of fentanyl and tramadol as analgesics in renal colic patients.
Materials and Methods
Our research is a prospective, randomized, double-blind study. We administered intravenous(iv) non-steroid anti-inflammatory drugs as first line treatment. Then, “iv Fentanyl” and “iv Tramadol” were administered to the patients whose pain did not relieve. The outcomes of the analgesic efficacy in our study are the difference between VAS0-VAS 60 values and the score less than 4 in VAS 60.
Results
A total of 912 renal colic patients were admitted during the study period. When the exclusion criteria were applied, the study is completed with 143 patients. The difference between VAS0 and VAS 60 values-which is the primary outcome in the evaluation of analgesic efficiency in our study is 6,11±2,49 in Fentanyl and 5,94±2,40i n Tramadol group. In the fentanyl group, 16 patients responded to the treatment and in the tramadol group 18 patients responded to the treatment.
Conclusions
Our study is concluded that both drugs are effective on renal colic pain and they do not have a significant advantage over each other.
