研究目的: |
本项目旨在评估布比卡因脂质体经外周神经阻滞在儿童下肢大手术后的镇痛效果与安全性。小儿骨科下肢矫形术创伤性大、术后疼痛剧烈而持久,即使采用多模式镇痛,患儿对急性疼痛管理的满意度仍然较低,且在术后可能面临阿片类药物过量的风险,因此,寻找更为安全有效的镇痛方案至关重要。布比卡因脂质体作为一种新型长效局麻药,其缓释特性能够显著延长镇痛持续时间,提供更持久的镇痛效果。本研究采用随机对照试验设计,通过临床研究对比布比卡因脂质体与盐酸布比卡因,经外周神经阻滞对儿童下肢矫形术术后疼痛的影响,从而为这类手术寻找更好的术后镇痛方案和药物。 |

Objectives of Study: |
This project aims to evaluate the analgesic effect and safety of bupivacaine liposomes after major surgery for lower limbs in children. Pediatric orthopedic lower limb orthopedics is traumatic and has severe and long-lasting postoperative pain. Even with multimodal analgesia, children's satisfaction with acute pain management is still low and they may face the risk of opioid overdose after the operation. Therefore, it is crucial to find safer and more effective analgesic options. As a new long-acting local anesthetic, bupivacaine liposomes have a sustained release property that can significantly prolong the duration of analgesia and provide a more lasting analgesic effect. This study adopts a randomized controlled trial design, and through clinical studies, the effects of bupivacaine liposomes and bupivacaine hydrochloride, transsurface nerve block on postoperative pain in children's lower limb orthopedic surgery were compared, thereby finding better postoperative analgesia plans and drugs for this type of surgery. |
