Abstract

BACKGROUND

During drilling of bone, which is common in clinical surgeries, heat generation increases local temperature in the drilling site. Transmission of excessive heat to the surrounding bone tissue can cause thermal osteonecrosis. Consequently, it may lead to failure of implants and fixation screws or delay in healing process. Using cooling is a method for limiting temperature elevation.

MATERIALS AND METHODS

In this study, through comparing three conditions of drilling without cooling, external cooling with normal saline, and external cooling with OpSite spray, the efficiency of OpSite as coolant is studied. In this regard, 2 drill bit diameters, 3 drilling speeds, and 3 drilling feed-rates are considered as drilling variables in the experiments.

RESULTS

For the whole experiments, while cooling with normal saline resulted in lower maximum temperatures than without cooling condition, OpSite had even better results and limited the temperature elevation during drilling of bone efficiently.

CONCLUSION

OpSite spray, which has lower infection risks than normal saline on one hand and lower maximum temperature rise with all combinations of drilling parameters on the other hand, can be considered in clinical surgeries for cooling applications.

摘要

背景

在临床手术中常见的骨钻过程中,会产生热量从而使钻孔部位的局部温度升高。过多的热量传递到周围的骨组织会导致热骨坏死。因此,这可能会导致植入物和固定螺钉的失效,或愈合过程的延迟。使用冷却方法是限制温度升高的一种方法。

材料与方法

在这项研究中,通过比较不冷却、用生理盐水外部冷却和使用 Opsite 喷雾外部冷却三种情况,研究了 Opsite 作为冷却剂的效率。在实验中,考虑了 2 种钻头直径、3 种钻孔速度和 3 种钻孔进给速度作为钻孔变量。

结果

对于整个实验,生理盐水冷却的最高温度低于不冷却的情况,但 Opsite 的效果更好,有效地限制了骨钻过程中的温度升高。

结论

OpSite 喷雾一方面比生理盐水感染风险低,另一方面在所有钻孔参数组合下最高温度上升都较低,可在临床手术中考虑用于冷却应用。
