研究目的:

主要目的:本研究拟进行瑞芬太尼应用于学龄期儿童人工耳蜗植入术,确定瑞芬太尼的半数有效浓度(EC50)、半数有效剂量(ED50)与95%有效剂量(ED95),为临床应用优化麻醉方案提供参考。 次要目的:降低或消除学龄期儿童人工耳蜗植入术气管拔管过程中的呛咳、血流动力学波动、躁动,减少术后并发症的发生,提供临床措施和理论证据。  

Objectives of Study:

Main objective: This study aims to apply remifentanil in cochlear implantation surgery for school-age children, determine the half effective concentration (EC50), half effective dose (ED50), and 95% effective dose (ED95) of remifentanil, and provide reference for optimizing anesthesia regimens in clinical applications. Secondary objective: To reduce or eliminate coughing, hemodynamic fluctuations, and agitation during tracheal extubation in school aged children undergoing cochlear implantation surgery, reduce the occurrence of postoperative complications, and provide clinical measures and theoretical evidence.

干预措施:

瑞芬太尼初始靶控输注浓度2.0 ng/mL,根据序贯法,预设以0.2 ng/mL梯度调整。在文献基础上,对咳嗽进行分级:[0:无咳嗽;1:轻度咳嗽,仅1次,无躁动;2:中度咳嗽,>1次,但持续<5s,有躁动但不影响拔管;3:持续咳嗽>5s,伴有抬头、屏气、发绀等。一旦MAP或HR超过基础值的20%和/或出现中、重度咳嗽意味着拔管反应的发生,下一位患者使用瑞芬太尼的目标靶控浓度增加0.2ng/mL。相反,如果拔管成功,瑞芬太尼的目标靶控浓度降低0.2ng/mL。进行气管拔管并评估“成功”或“失败”的麻醉师不知道瑞芬太尼靶控浓度。

干预措施代码:

Intervention:

The initial target controlled infusion concentration of remifentanil is 2.0 ng/mL, and according to the sequential method, it is preset to be adjusted in a gradient of 0.2 ng/mL. Based on the literature, cough is classified as follows: [0: no cough; 1: mild cough, only once, no agitation; 2: moderate cough,>once, but lasting<5s, with agitation but not affecting extubation; 3: Persistent cough for more than 5 seconds, accompanied by head lifting, breath holding, cyanosis, etc. Once the MAP or HR exceeds 20% of the baseline value and/or moderate to severe coughing occurs, indicating the occurrence of extubation reaction, the target controlled concentration of remifentanil for the next patient will increase by 0.2ng/mL. On the contrary, if extubation is successful, the target controlled concentration of remifentanil decreases by 0.2ng/mL. The anesthesiologist who performed tracheal extubation and evaluated whether it was "successful" or "failed" did not know the target controlled concentration of remifentanil.

干预措施:

瑞芬太尼初始输注速率为0.06μg/kg/min,相邻两组输注速率差异为0.01μg/kg/min。在文献基础上,对咳嗽进行分级:[0:无咳嗽;1:轻度咳嗽,仅1次,无躁动;2:中度咳嗽,>1次,但持续<5s,有躁动但不影响拔管;3:持续咳嗽>5s,伴有抬头、屏气、发绀等。一旦MAP或HR超过基础值的20%和/或出现中、重度咳嗽意味着拔管反应的发生,下一位患者使用瑞芬太尼的输注速率增加0.01μg/kg/min。相反,如果拔管成功,瑞芬太尼的输注速率减少0.01μg/kg/min。进行气管拔管并评估“成功”或“失败”的麻醉师不知道瑞芬太尼输注速率。

干预措施代码:

Intervention:

The initial infusion rate of remifentanil is 0.06 μ g/kg/min, and the difference in infusion rate between adjacent groups is 0.01 μ g/kg/min. Based on the literature, cough is classified as follows: [0: no cough; 1: mild cough, only once, no agitation; 2: moderate cough,>once, but lasting<5s, with agitation but not affecting extubation; 3: Persistent cough for more than 5 seconds, accompanied by head lifting, breath holding, cyanosis, etc. Once the MAP or HR exceeds 20% of the baseline value and/or moderate to severe coughing occurs, indicating the occurrence of extubation reaction, the infusion rate of remifentanil for the next patient will increase by 0.01 μ g/kg/min. On the contrary, if extubation is successful, the infusion rate of remifentanil decreases by 0.01 μ g/kg/min. The anesthesiologist who performed tracheal extubation and evaluated whether it was "successful" or "failed" did not know the infusion rate of remifentanil.
