Lidocaine-loaded nanoparticles are versatile nanomaterials that may be used in pain treatment due to their wound healing properties. The current study describes a wound dressing formulation focused on lidocaine-loaded dextran/ethylene glycol nanoparticles (an anesthetic drug). The lidocaine-loaded dextran/ethylene glycol membranes were fabricated using lidocaine solutions inside the dextran/ethylene glycol medium. The influence of various experimental conditions on dextran/ethylene glycol nanoparticle formations were examined. The sizes of dextran/ethylene glycol and lidocaine-loaded dextran/glycol nanoparticles were examined through the HR-SEM. Moreover, the efficacy antibacterial activity of dextran/glycol and lidocaine-loaded dextran/ethylene glycol nanoparticles was evaluated against the microorganisms grampositive and negative. Furthermore, we observed the wound healing of wounds in skin using a mice model over a 16 days period. In this difference to the wounds of untreated mouse, quick healing was observed in the lidocaine-loaded dextran/glycol nanoparticles-treated wounds with fewer injury. These results specify that lidocaine-loaded dextran/ethylene glycol nanoparticles-based dressing material could be a ground-breaking nanomaterial having wound repair and implantations potential required for wound injury in pain management, which was proven using an animal model.
载利多卡因纳米颗粒是一种多功能纳米材料,由于其具有伤口愈合特性,可用于疼痛治疗。本研究描述了一种载利多卡因的葡聚糖/乙二醇纳米颗粒(一种麻醉药物)的伤口敷料配方。载利多卡因的葡聚糖/乙二醇膜是通过在葡聚糖/乙二醇介质内的利多卡因溶液制备的。研究了各种实验条件对葡聚糖/乙二醇纳米颗粒形成的影响。通过高分辨率扫描电子显微镜(HR-SEM)检查了葡聚糖/乙二醇和载利多卡因的葡聚糖/乙二醇纳米颗粒的大小。此外,评估了葡聚糖/乙二醇和载利多卡因的葡聚糖/乙二醇纳米颗粒对革兰氏阳性和阴性微生物的抗菌活性。此外,我们观察了载利多卡因的葡聚糖/乙二醇纳米颗粒处理的皮肤伤口在 16 天内的愈合情况。与未治疗的小鼠的伤口相比,在利多卡因载药的葡聚糖/乙二醇纳米颗粒处理的伤口中,观察到了更快的愈合,并且伤口的损伤更少。这些结果表明,载利多卡因的葡聚糖/乙二醇纳米颗粒基敷料材料可能是一种具有开创性的纳米材料,具有伤口修复和植入的潜力,可用于疼痛管理中的伤口损伤,这已通过动物模型得到证实。
