In the past decade, the implantable Doppler probe has been studied widely as a blood flow-monitoring device in reconstructive and transplant surgical specialities. Its utility as an effective postoperative monitoring technique is still debatable, with no clear guidelines in clinical practice. Here, we mapped the current evidence on the usefulness of the implantable Doppler probe as a blood flow-monitoring device. The objective was to present an up-to-date assessment of the benefits and limitations of using implantable Doppler probes in clinical and experimental clinical settings.
We conducted a literature search using the Cochrane Library and Healthcare Databases Advanced Search and using implantable Doppler probe, transplant, graft, and flap as key words. The search yielded 184 studies, with 73 studies included after exclusions. We evaluated, synthesized, and summarized the evidence from the studies in tabular form.
There is clinical equipoise regarding the effectiveness of implantable Doppler probe as a flow sensing technique. The main reason is the lack of information and gaps in the evidence regarding the benefits and limitations of using implantable Doppler probes in clinical practice.
The implantable Doppler probe has the potentialto be used as an adjunctpostoperativeblood flow-monitoring device. However, keeping in view of technical limitations, its signals should be interpreted alongside traditional clinical assessment techniques to determine the patency of microvascular anastomosis. Although evidence in this review will inform clinical practice in transplant and reconstructive surgical specialties, a prospective randomized controlled study with a larger patient cohort is required to evaluate the effectiveness of this probe in clinical settings.
在过去十年中，植入式多普勒探头作为一种血流监测设备，在重建和移植外科专业中得到了广泛研究。其作为一种有效的术后监测技术的效用仍存在争议，临床实践中也没有明确的指南。在此，我们对植入式多普勒探头作为血流监测设备的有用性进行了现有证据的评估。目的是对在临床和实验临床环境中使用植入式多普勒探头的益处和局限性进行最新评估。
我们使用 Cochrane 图书馆和医疗保健数据库高级搜索进行文献检索，并使用植入式多普勒探头、移植、移植物和皮瓣作为关键词。搜索共得到 184 项研究，排除后纳入 73 项研究。我们以表格形式评估、综合和总结研究中的证据。
在植入式多普勒探头作为流量感应技术的有效性方面存在临床均衡。主要原因是缺乏关于在临床实践中使用植入式多普勒探头的益处和局限性的信息和证据差距。
植入式多普勒探头有可能作为一种辅助术后血流监测设备使用。然而，鉴于技术限制，其信号应与传统的临床评估技术结合使用，以确定微血管吻合术的通畅性。虽然本综述中的证据将为移植和重建外科专业的临床实践提供信息，但需要一项前瞻性随机对照研究，纳入更大的患者队列，以评估该探头在临床环境中的有效性。
