Background: The use of intravenous lidocaine for analgesia in patients presenting to the emergency department (ED) with renal colic has gained recent traction and interest, and was previously explored on the REBEL EM blog. Literature has been mixed, with one trial (Soleimanpour 2012) demonstrating analgesic benefit, but two smaller trials (Firouzian 2016) (Motamed 2017) finding no such role for IV lidocaine. Nonetheless, uptake has been brisk (Fitzpatrick 2016). The authors of this study (The LIDOKET Trial) sought to better define the utility of IV lidocaine for the treatment of renal colic.
