研究目的:

主要目的:本研究旨在探索一种药物最佳剂量,其结果可能为儿科麻醉学提供新的思路,有助于降低术后低氧风险,提高患儿安全及围术期舒适度。探讨Dixon法青春期小儿隐匿阴茎手术中最佳罗哌卡因剂量。次要目的:观察小剂量腰麻对患儿血流动力学的影响,分析小剂量腰麻的术后镇痛效果及不良反应  

Objectives of Study:

The aim of this study is to explore the optimal dose of a drug, the results of which may provide new ideas for pediatric anesthesiology, help reduce the risk of postoperative hypoxia, and improve the safety and perioperative comfort of children. To investigate the optimal dose of ropivacaine in adolescent children undergoing penile occult operation with Dixon method. Secondary objective: To observe the effect of low-dose lumbar anesthesia on hemodynamics in children, and to analyze the postoperative analgesic effect and adverse reactions of low-dose lumbar anesthesia

干预措施:

Dixon法:采用改良的Dixon序贯法进行试验,。果蛛网膜阻滞失败,则增加后续受试者的罗哌卡因剂量,反之(即阴性反应),则减少剂量。患儿间固定增量或递减剂量为0.01 mg/kg。正式测试从第一个交叉波开始,一直持续到第八个交叉波出现。

干预措施代码:

None

Intervention:

Dixon method: The modified Dixon sequential method was used for the experiment. If the caudal epidural block fails, the ropivacaine dose for subsequent subjects is increased; conversely (i.e., negative response), the dose is decreased. The fixed incremental or decremental dose between children is 0.01 mg/kg. The formal test starts from the first crossover wave and continues until the eighth crossover wave appears.
