Clinical Trial Summary

This is a prospective interventional study examining the effect of ketorolac at doses of 15mg versus 30 mg for duration of analgesia in emergency department patients with suspected renal colic.


Description:

Pain is a common emergency department complaint. With various types of analgesics available, the optimal drug is one that provides adequate pain management with minimal side effects. The goal is to effectively treat the patient while maintaining adequate flow in the emergency department. In cases of moderate to severe pain in emergency departments, opioids have been the gold standard.1 Opiates, such as morphine, are associated with side effects that can be distressing to the patient, as well as, costly to the department. Prescribing opiates includes a reluctance in administering sufficient opioid dosing due to fear of tolerance and dependency.2 It has been demonstrated in other studies that the standard dosing of ketorolac is higher than needed to achieve analgesia but have failed to show to what duration of time analgesia is maintained between the dosages. The study will compare the analgesic efficacy of two doses of intravenous ketorolac (15mg and 30mg) for acute flank pain in the Emergency Department (ED), such as renal colic, and how efficacious the pain was controlled at 120 minutes or upon discharge. Motov et al evaluated the effectiveness of ketorolac in moderate to severe pain with a primary endpoint of 30 minutes, however the peak onset of ketorolac is 120 to 180 minutes. Our study may further investigate the ceiling dose of intravenous ketorolac. The primary outcome of both Motov et al and Eidinejad et al was pain reduction 30 minutes after ketorolac administration.3,4 These studies differed in the aspect that Eidinejad et al study examined pain reduction up to 60 minutes, while Motov et al observed up to 120 minutes after administration of ketorolac.3,4 Ketorolac has a peak time of onset at 2 to 4 hours. These studies are not observing ketorolac at its optimal analgesic potency. Therefore, a study is proposed to compare 15 mg vs 30 mg intravenous ketorolac with the primary outcome being pain reduction in renal colic at 120 minutes. Nephrolithiasis and ureterolithiasis are the most common diagnoses in the emergency department for which ketorolac is prescribed.5 This study may further evaluate optimal intravenous ketorolac dosing in pathology it is known to be the most advantageous.

Outcome

Type Measure Description Time frame Safety issue
Primary Change in pain scale post ketorolac administration This study may prospectively compare the mean Numerical Rating Scale (NRS) pain score reduction of 15 mg versus 30 mg of intravenous (IV) ketorolac at 120 minutes after administration to treat renal colic in the emergency department. The scale ranges from 0 to 10 with 0 being "no pain" and 10 being "very much pain". At 120 minutes from medication administration
Secondary Change in pain scale post ketorolac administration at different time points This study may also determine the mean NRS pain score reduction at different time points (90 minutes, 150 minutes, and 180 minutes) after IV ketorolac administration. The scale ranges from 0 to 10 with 0 being "no pain" and 10 being "very much pain". At 90 minutes from medication administration
Secondary Change in pain scale post ketorolac administration at different time points This study may also determine the mean NRS pain score reduction at different time points (90 minutes, 150 minutes, and 180 minutes) after IV ketorolac administration. The scale ranges from 0 to 10 with 0 being "no pain" and 10 being "very much pain". At 150 minutes from medication administration
Secondary Change in pain scale post ketorolac administration at different time points This study may also determine the mean NRS pain score reduction at different time points (90 minutes, 150 minutes, and 180 minutes) after IV ketorolac administration. The scale ranges from 0 to 10 with 0 being "no pain" and 10 being "very much pain". At 180 minutes from medication administration
Secondary Need for additional rescue analgesia Study may also examine the number of patients requesting rescue analgesia within two hours of ketorolac administration (yes vs. no) At 120 minutes from medication administration
Secondary Type of additional rescue analgesia needed For the patients who need additional pain medication, we will collect the type of medication provided. At 120 minutes from medication administration
Secondary Dose of additional rescue analgesia needed For the patients who need additional pain medication, we will collect the dose of medication provided. At 120 minutes from medication administration
