Clinical Trial 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.

Intervention

Procedure:
Erector Spinae plane block using 20 ml of bupivicaine 0.25%
Utilizing the in line approach, a 22 gauge 3.5" spinal needle was guided the the tip of the transverse process corresponding to the area of maximal tenderness or central to the reported area of spasm. 1% lidocaine with epinephrine was used for skin anaesthesia and for hydro-localization of the needle tip on approach to the tip of the transverse process. Once the needle tip made contact with the transverse process, 2-3 ml of 1% lidocaine with epinephrine was injected to open the ESP plane. If there was no reported tachycardia after approximately 45 seconds, 20 ml of 0.25% bupivicaine was injected into the ESP plane.
Drug:
Usual care
Analgesia as dictated by the treating emergency physician

Outcome

Type Measure Description Time frame Safety issue
Primary Numeric Verbal Pain Score (NVPS) reduction at emergency department discharge The NVPS is an 11-point verbal pain scale from 0 to 10 with 0 representing no pain and 10 the worst pain imaginable. 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.
Secondary Number of patients requiring post randomization Emergency department (ED) opiate analgesia analgesia use Opiate medication dose and route of administration was recorded Time of randomization to time of ED discharge up to 24 hours after randomization.
Secondary Emergency department (ED) length of stay. Time spent in the emergency department. Time of ED triage to time of ED discharge up to 24 hours after triage.
Secondary Brief Pain Inventory (BPI) score reduction from baseline 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 Time of randomization compared to 1 day, 1 week, 1 month, and 3 months post Emergency department visit
Secondary Number of patients requiring post Emergency department discharge opiate analgesia use During telephone follow up, patients were asked if there was any opiate analgesia used during the pre-determined time period. 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.
Secondary Post Emergency department (ED) discharge Numeric Verbal Pain Score (NVPS) 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 1 day after randomization, 1 week after randomization, 1 month after randomization, 3 months after randomization.
Secondary Number of patients able to ambulate post ED treatment if unable to on ED admission If patient was unable to ambulate on ED admission, did ED treatment allow ambulation without assistance: yes or no Time of ED triage compared to time of ED discharge up to 24 hours after triage.
Secondary Number of patients requiring Emergency department (ED) return visits for back pain 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 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.
