Erector Spinae Plane Block vs. Usual Care for ED Patients With Mechanical Back Pain
- Conditions
- Back Pain
- Interventions
- Procedure: Erector Spinae plane block using 20 ml of bupivicaine 0.25%Drug: Usual care
- Registration Number
- NCT05982483
- Lead Sponsor
- Island Health
- Brief Summary
The goal of this clinical trial is to compare the Erector Spinae plane (ESP) block, a nerve block, to usual care in emergency department patients with back pain. The main question it aims to answer:
Is the ESP block superior to usual care in the treatment of back pain in the emergency department? Participants will be randomly assigned to the ESP or the usual care group. Pain improvement at the time of emergency department discharge will be compared.

- Primary Outcome Measures
Name Time Method Numeric Verbal Pain Score (NVPS) reduction at emergency department discharge Numeric verbal pain score (NVPS) at time of randomization compared with NVPS at time of discharge from the emergency department up to 24 hours after randomization. The NVPS is an 11-point verbal pain scale from 0 to 10 with 0 representing no pain and 10 the worst pain imaginable.
- Secondary Outcome Measures
Name Time Method Number of patients requiring post randomization Emergency department (ED) opiate analgesia analgesia use Time of randomization to time of ED discharge up to 24 hours after randomization. Opiate medication dose and route of administration was recorded
Emergency department (ED) length of stay. Time of ED triage to time of ED discharge up to 24 hours after triage. Time spent in the emergency department.
Brief Pain Inventory (BPI) score reduction from baseline Time of randomization compared to 1 day, 1 week, 1 month, and 3 months post Emergency department visit The Brief Pain Inventory (BPI) is widely used to measure a patients' pain intensity and interference the pain has on daily function measured in 7 categories: mood, work, general activity, walking, relationships, enjoyment of life, and sleep. The patient rates each of these on a scale from 0-10with 0 representing no interference and 10 complete interference in that aspect of life. The initial BPI was recorded at time of randomization and subsequent BPI's recorded by telephone follow-up at predetermined time intervals
Number of patients requiring post Emergency department discharge opiate analgesia use Date of randomization to 1 day after randomization, 1 day after randomization to 1 week after randomization, 1week after randomization to 1 month after randomization, 1 month after randomization to 3 months after randomization. During telephone follow up, patients were asked if there was any opiate analgesia used during the pre-determined time period.
Post Emergency department (ED) discharge Numeric Verbal Pain Score (NVPS) 1 day after randomization, 1 week after randomization, 1 month after randomization, 3 months after randomization. At telephone follow up at predetermined time intervals, patients were asked what their most severe level of pain they were currently experiencing as measured by the NVPS
Number of patients able to ambulate post ED treatment if unable to on ED admission Time of ED triage compared to time of ED discharge up to 24 hours after triage. If patient was unable to ambulate on ED admission, did ED treatment allow ambulation without assistance: yes or no
Number of patients requiring Emergency department (ED) return visits for back pain Date of randomization to 1 day after randomization, 1 day after randomization to 1 week after randomization, 1week after randomization to 1 month after randomization, 1 month after randomization to 3 months after randomization. At telephone follow up at predetermined intervals, patients were asked if they had to return subsequently to the emergency department due to their back pain
