局部疼痛的按需缓解将允许患者以安全和非侵入性的方式控制神经阻滞的时间、强度和持续时间。超声波将是这种系统的合适触发器,因为它是常见的临床使用,并且可以深入到身体中。在这里,我们证明了超声触发的脂质体麻醉剂的输送允许神经阻滞的时间,强度和持续时间由超声参数控制。在超声作用下,包封的声致敏剂原卟啉IX产生与脂质体膜反应的活性氧,导致释放强效局部麻醉剂河豚毒素。我们还显示了可重复的超声波触发的神经阻滞在体内,神经阻滞的持续时间取决于程度和强度的insonation。我们没有检测到任何全身毒性,所有组的组织反应均为良性。按需,个性化的局部麻醉可能有利于管理相对局部的疼痛状态,并可能最大限度地减少阿片类药物的使用。
On-demand relief of local pain would allow patients to control the timing, intensity and duration of nerve block in a safe and non-invasive manner. Ultrasound would be a suitable trigger for such a system, as it is in common clinical use and can penetrate deeply into the body. Here, we demonstrate that ultrasound-triggered delivery of an anaesthetic from liposomes allows the timing, intensity and duration of nerve block to be controlled by ultrasound parameters. On insonation, the encapsulated sonosensitizer protoporphyrin IX produces reactive oxygen species that react with the liposomal membrane, leading to the release of the potent local anaesthetic tetrodotoxin. We also show repeatable ultrasound-triggered nerve blocks in vivo, with nerve-block duration depending on the extent and intensity of insonation. We did not detect any systemic toxicity, and tissue reaction was benign in all groups. On-demand, personalized local anaesthesia could be beneficial for the managing of relatively localized pain states, and potentially minimize opioid use.
