Abstract
- Background: The ultrasound-guided erector spinae plane block (ESPB), traditionally utilized for thoracic regional pain control, has been reported as an effective analgesic option for mechanical back pain, renal colic, and rib fractures in the emergency department (ED). This pilot study aims to compare the effectiveness of the ESPB to usual analgesic treatment for patients presenting to the ED with mechanical back pain.<br />Methods: A prospective, single-blind randomized controlled trial was conducted at a Canadian community hospital from March 2020 to December 2022. Adult patients presenting to the ED with mechanical back pain of at least 7 out of 10 on the Numeric Pain Rating Scale (NPRS) were randomized to receive either the ESPB or usual care. The primary outcome was the difference in NPRS score reduction at ED discharge. Secondary outcomes included ED length of stay, ED opiate use, follow-up NPRS and Brief Pain Inventory (BPI) scores, back pain-related return ED visits, and ongoing opiate use.<br />Results: A total of 30 patients were enrolled, with 19 randomized to the ESPB cohort and 11 to the usual care cohort. The mean NPRS reduction at ED discharge was significantly higher in the ESPB group compared to the usual care group (5.4 vs. 2.2), with a difference of 3.2 (95% confidence interval 1.4-5.1). ED opiate use was lower in the ESPB group. The ESPB also resulted in a significant reduction in ED length of stay (160 min vs. 235 min). There were no reported adverse effects related to the research interventions.<br />Conclusion: This pilot study suggests that the ESPB may be an effective opioid-sparing analgesic option for patients presenting to the ED with mechanical back pain.<br />Gov Identifier: NCT05982483.<br /> (© 2024.
