摘要

Background

Fluoroscopically guided caudal epidural injections are commonly used to treat lumbar back pain with radiculopathy. Whilst hospitals internationally advise against driving for 12–24 h post injection, there are currently no standardised guidelines on when it is safe to resume driving post injection.

Aims

To assess if brake response times are altered pre and post fluoroscopic-guided caudal epidural nerve root injections.

Methods

Brake response times were assessed before and after fluoroscopic-guided caudal epidural nerve root injections in a cohort of patients. The average of 3 brake response times was recorded before and 30 min after injection. Statistical analysis was performed using GraphPad. A paired Student t-test was used to compare the times before and after the injections.

Results

Fifty two patients were included in this study. The mean age was 60 years. There were 25 male and 27 female patients. Mean pre-injection brake response time was 0.91 s (range 0.6–1.3), compared with 0.96 s (range 0.6–1.4) post-injection. The difference was not statistically significant (p = 0.41) in mean brake response times.

Conclusions

Brake response time did not significantly differ pre and 30 min post fluoroscopic-guided caudal epidural nerve root injections. These findings demonstrate similar response times under simulated conditions but do not establish definitive driving safety.
