Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: ESP Nerve Block for Renal colic<br>On top of receiving standard of care, At T8 nerve level, with ultrasound guidance to bathe the nerve | Drug: Ropivacaine injection<br>* Local anesthesia injected under ultrasound guidance<br>|
| Active Comparator: Standard of care<br>Whatever medications the clinician normally treats renal colic with | Other: Standard of care medications<br>* Whatever the ED clinicians normally give for renal colic pain<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Baseline Pain before intervention | Using the Visual Analog Scale for Pain Assessment Tool with 0 meaning No pain and 10 meaning Unbearable Pain | Before the ESP Block | 
| Pain score at 10 minutes | Using the Visual Analog Scale for Pain Assessment Tool with 0 meaning No pain and 10 meaning Unbearable Pain | 10 minutes after the ESP Block | 
| Pain score at 20 minutes | Using the Visual Analog Scale for Pain Assessment Tool with 0 meaning No pain and 10 meaning Unbearable Pain | 20 minutes after ESP Block | 
| Pain score at 40 minutes | Using the Visual Analog Scale for Pain Assessment Tool with 0 meaning No pain and 10 meaning Unbearable Pain | 40 minutes after ESP Block | 
| Pain score at 60 minutes | Using the Visual Analog Scale for Pain Assessment Tool with 0 meaning No pain and 10 meaning Unbearable Pain | 60 minutes after ESP Block | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Need for extra opiates | Record how much opioids patients receives starting after the ESP Block for both the standard of care patients and the ESP Block group | Starting from time 0 after the ESP Block intervention completed till discharge or urology intervention |
