我们开发了一种利用光声效应改善针尖可见性的新技术。我们评估了在身体模型中进行深部周围神经阻滞时，这项技术是否改善了针尖的可见性。利用传统的腔内光纤回声针研制了一种光声针。脉冲激光将来自光源的光通过光纤发送，利用光声效应在针尖将其转换为超声波。神经阻滞专家使用光声针和记录的超声切面，在针尖有或没有光声超声的情况下进行深层神经阻滞。通过由麻醉师评估记录图像完成的问卷(Likert评分1：很差，5：很好)来评估针尖的可见性。得分以中位数[第一四分位数，第三四分位数]表示。统计分析采用Wilcoxon配对符号等级检验。使用光声超声的患者针尖可见度评分(4.3[4.0，4.5])显著高于不使用光声超声的患者(3.5[3.2，3.8])(p <； 0.0 1)。利用光声效应在针尖发射的超声波在深部周围神经阻滞期间改善了针尖的可见性。临床试验编号大学医院医学信息网络中心临床试验登记系统(UMIN000036974)。
We developed a novel technology using the photoacoustic effect that improve needle tip visibility. We evaluated whether this technology improves needle tip visibility when performing a deep peripheral nerve block in a cadaver model. A photoacoustic needle was developed using a conventional echogenic needle with an intraluminal optical fiber. A pulsed laser sends light from a source through the fiber, which is converted to ultrasound at the needle tip using the photoacoustic effect. A nerve block expert performed deep nerve blocks using the photoacoustic needle and the ultrasound views recorded, with or without photoacoustic ultrasound at the needle tip. Needle tip visibility was evaluated by questionnaire (Likert scale 1: very poor, 5: very good) completed by anesthesiologists evaluating recorded images. The score was presented as median [first quartile, third quartile]. Statistical analysis was performed using the Wilcoxon matched-pairs signed rank test. The scores of needle tip visibility with photoacoustic ultrasound from the needle tip (4.3 [4.0, 4.5]) was significantly higher than that without photoacoustic ultrasound (3.5 [3.2, 3.8]) (p < 0.01). Ultrasound emitted at the needle tip using the photoacoustic effect improves needle tip visibility during deep peripheral nerve blocks.
