Inclusion criteria

In this study, patients diagnosed with diabetic foot debridement and drainage, toe amputation or foot amputation in Hainan Provincial People's Hospital were selected, and the patients agreed to the anesthesia method of lumbo-epidural anesthesia. All patients signed informed consent, regardless of gender or age, BMI<35kg/m2, and ASA grade I-III.

干预措施:

使用罗哌卡因9mg的初始剂量,在蛛网膜下隙注射后15分钟内达到T12节段的双侧感觉阻滞,手术完成或在蛛网膜下隙注射后至少6分钟内不进行硬膜外补充,则记录为成功。罗哌卡因的剂量根据先前受试者的反应来确定,按照偏置硬币方法,上下间隔剂量为1mg。如果一个受试者没有反应成功,下一个受试者的剂量增加1mg。相比之下,如果受试者反应成功,则罗哌卡因剂量以10%的概率减少1mg,并以90%的概率保持当前剂量。

干预措施代码:

Intervention:

Bilateral sensory block at T12 level was achieved within 15 minutes after subarachnoid injection using an initial dose of 9mg ropivacaine, and success was recorded when surgery was completed or no epidural supplementation was performed for at least 6 minutes after subarachnoid injection. The dose of ropivacaine was determined based on the response of previous subjects, with an upper and lower interval dose of 1mg following the offset coin method. If one subject does not respond successfully, the dose of the next subject is increased by 1mg. In contrast, if the subject responded successfully, the ropivacaine dose was reduced by 1mg with a 10% probability and the current dose was maintained with a 90% probability.
