Thermal diffusion flowmetry is a continuous quantitative technique of measuring regional cerebral blood flow utilizing a silastic strip probe placed through a craniotomy or craniectomy in the operating room. A new bolt like application of this technology is now available for commercial use and is especially designed for bedside placement in trauma patients. This new trauma bolt is tested in juvenile pigs who are subjected to episodes of hypercapnea to increase cerebral blood flow, and records significant changes in blood flow. Another feature of the trauma bolt is a second port for the placement of an intracranial pressure (ICP) monitor. Placement of the probe and ICP monitor were easier than with the silastic probe and had relatively little complication.
热扩散血流测定法是一种连续定量测量局部脑血流量的技术，它利用一个硅橡胶条探头，通过在手术室进行的开颅术或颅骨切除术放置。这项技术的一种新型螺栓状应用现已可供商业使用，并且是专门为创伤患者床边放置而设计的。这种新型创伤螺栓在幼年猪身上进行了测试，这些猪经历了高碳酸血症发作以增加脑血流量，并记录到血流量的显著变化。创伤螺栓的另一个特点是有第二个端口用于放置颅内压（ICP）监测器。探头和ICP监测器的放置比硅橡胶探头更容易，且并发症相对较少。
