Transcranial Doppler ultrasonography has been used to detect microemboli in the middle cerebral artery during orthopedic surgery. We conducted a comprehensive systematic literature review of transcranial Doppler ultrasonography in orthopedic surgery to evaluate its status in this setting. Fourteen studies were selected for qualitative analysis. The highest number of patients studied was 45; emboli were detected in all studies, occurring in 20%-100% of patients. Most embolic counts were below 10, but some high counts were noted. No study reported all the technical parameters of the transcranial Doppler ultrasonography. All studies assessed neurologic status, and 6 studies evaluated cognitive function postoperatively. No study identified an association between postoperative cognitive function and embolic count. Six studies sought the presence of right-to-left shunts.
经颅多普勒超声已被用于在骨科手术期间检测大脑中动脉的微栓子。我们对经颅多普勒超声在骨科手术中的应用进行了全面的系统文献综述，以评估其在这种情况下的地位。选择了14项研究进行定性分析。研究的患者数量最多为45例；所有研究均检测到栓子，发生率为20%-100%。大多数栓子计数低于10，但也有一些高计数情况。没有研究报告经颅多普勒超声的所有技术参数。所有研究均评估了神经状态，6项研究评估了术后认知功能。没有研究发现术后认知功能与栓子计数之间存在关联。6项研究探寻了右向左分流的存在情况。
