To assess if brake response times are altered pre and post CT-guided cervical spine nerve root injections.
Brake response times were assessed before and after CT-guided cervical spine 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.
Forty patients were included in this study. The mean age was 55 years. There were 17 male and 23 female patients. There was no significant difference in the mean pre and post CT-guided cervical spine nerve root injection brake response times; 0.94 s (range 0.4-1.2 s) and 0.93 s (range 0.5-1.25 s), respectively (P = .77).
Brake response time did not significantly differ pre and 30 min post CT-guided cervical spine nerve root injections.
To the authors' best knowledge, there are no current studies assessing brake response times post CT-guided cervical spine nerve root injections. While driving safety cannot be proven by a single metric, it is a useful study in demonstrating that this is not inhibited in a cohort of patients.
评估 CT 引导下颈椎神经根注射前后刹车反应时间是否改变。
对一组患者在 CT 引导下颈椎神经根注射前后进行刹车反应时间评估。记录注射前和注射后 3 次刹车反应时间的平均值。使用 GraphPad 进行统计分析。采用配对学生 t 检验比较注射前后的时间。
本研究共纳入 40 例患者。平均年龄为 55 岁。男性 17 例，女性 23 例。CT 引导下颈椎神经根注射前后平均刹车反应时间无显著差异；分别为 0.94s（范围 0.4-1.2s）和 0.93s（范围 0.5-1.25s）（P=0.77）。
CT 引导下颈椎神经根注射前后刹车反应时间无显著差异。
据作者所知，目前尚无研究评估 CT 引导下颈椎神经根注射后刹车反应时间。虽然单次测量无法证明驾驶安全性，但该研究有助于证明在一组患者中，颈椎神经根注射并未抑制这一反应。
