Treatment of Renal Colic by Nerve Blockade with Lidocaine Versus Intravenous Dexketoprofen

Abstract

Objective: To compare non-steroidal anti-inflammatory drugs (NSAIDs) with spinal nerve blockade of related dermatomes using lidocaine for pain palliation of patients admitted to the Emergency Department (ED) with an episode of renal colic.

Study design: Randomised controlled-trial.

Place and duration of study: Department of Emergency Medicine, Kartal Dr. Lütfi Kırdar City Hospital, İstanbul, Turkey from May to July 2019.

Methodology: The study included patients admitted to the ED with renal colic randomised into two groups: first group received 2% lidocaine for nerve blockage and the second group received intravenous injection of 50 mg dexketoprofen. All patients were asked to rate the intensity of their pain and on a 0 to 10 point visual analogue scale before and at 5, 15, 30, 45, and 60 minutes after intervention.

Results: A total of 126 patients, 56 women and 70 men, were inducted. There were statistically significant differences in the median VAS scores for pain from the 5th minute to the 60th minute in favour of lidocaine.

Conclusion: Spinal nerve blocks with 2% lidocaine resulted in greater short-term pain relief than intravenous dexketoprofen in ED patients with renal colic. Key Words: Renal colic, NSAID, lidocaine, Nerve blockade.
