Intradermal Sterile Water Injection: Safe and Effective Alternative for Relief of Acute Renal Colic in the Emergency Department.

The optimal pain relief method for acute renal colic in the emergency department remains controversial. We compared the safety and efficacy of intradermal sterile water injection (ISWI) to treatment with intramuscular (IM) diclofenac, intravenous (IV) opioids, and IV paracetamol in patients with acute renal colic. This randomized, single-blind study included 320 patients with renal colic to one of four treatment groups. The first group received ISWI at four different points around the most painful flank area. Patients in the DI, PARA, and TRAM groups received 75 mg IM diclofenac, 1 g IV paracetamol, and 100 mg IV tramadol, respectively. Pain intensity was measured using a visual analog scale (VAS) before treatment and 15, 30, and 60 min after treatment. VAS scores 15 and 30 min after treatment were significantly lower in group ISWI than in groups DI, PARA, and TRAM. However, there were no significant differences in the decrease in the pain score at baseline and at 60 min after treatment. In addition, fewer patients required rescue analgesia in group ISWI than in group TRAM. However, no significant differences were observed between group ISWI and group DI or PARA in terms of the need for rescue analgesia. Finally, there were significantly fewer adverse events in group ISWI than in groups DI and TRAM. ISWI had similar efficacy, faster pain relief, and lower need for rescue analgesia compared with diclofenac, paracetamol, and tramadol for the management of acute renal colic. In addition, ISWI was well-tolerated and had no adverse effects. Copyright © 2023 Elsevier Inc. All rights reserved.
