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

Abstract

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 (i.v.) non-steroid anti-inflammatory drugs as first line treatment. Then, “i.v. fentanyl” and “i.v. tramadol” were administered to the patients whose pain did not relieve. The outcomes of the analgesic efficacy in our study were the difference between VAS 0-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 was completed with 143 patients. The difference between VAS 0 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±2.40 in tramadol group. While 16 patients responded to the treatment in the fentanyl group, 18 patients responded to the treatment in the tramadol group.Conclusion: Our study concluded that both drugs are effective on renal colic pain and they do not have a significant advantage over each other.
