Abstract

OBJECTIVE

To determine which of four methods of spinal immobilization causes the least ischemic pain.

METHODS

A prospective, nonblinded comparative trial was conducted at a statewide emergency medical services training facility using a convenience sample of emergency medical technician students. After lying motionless for 10 minutes, students evaluated each device using a 10-centimeter visual analog scale. Subjective comfort was used as a measure of ischemia.

RESULTS

Comfort scores were significantly different for all methods (F = 101, p < 0.001). A backboard padded with a gurney mattress and eggcrate foam (the equivalent of a spinal rehabilitation bed) caused the least ischemic pain (9.6 cm, 95% CI, 8.9 to 9.8 cm). A backboard padded with a gurney mattress was the second most comfortable device (7.0 cm, 95%/CI, 6.4 to 7.4 cm). A backboard padded with a folded blanket was the third most comfortable (3.3 cm, 95% CI, 2.6 to 4.9 cm). The backboard alone caused the most pain (0.8 cm, 95% CI, 0.7 to 2.1 cm).

CONCLUSION

Increasing the amount of padding on a backboard decreased the amount of ischemic pain caused by immobilization.

摘要

目的

确定四种脊柱固定方法中哪种引起的缺血性疼痛最少。

方法

在一个全州范围的紧急医疗服务培训设施中，对急救医疗技术员学生的便利样本进行了一项前瞻性、非盲法比较试验。学生们静止躺卧10分钟后，使用10厘米视觉模拟量表对每种设备进行评估。主观舒适度被用作缺血的衡量指标。

结果

所有方法的舒适度得分有显著差异（F = 101，p < 0.001）。铺有轮床床垫和泡沫蛋托（相当于脊柱康复床）的背板引起的缺血性疼痛最少（9.6厘米，95%可信区间，8.9至9.8厘米）。铺有轮床床垫的背板是第二舒适的设备（7.0厘米，95%可信区间，6.4至7.4厘米）。铺有折叠毛毯的背板是第三舒适的（3.3厘米，95%可信区间，2.6至4.9厘米）。单独的背板引起的疼痛最多（0.8厘米，95%可信区间，0.7至2.1厘米）。
