GroupA

干预措施:

采用此法时,麻醉医师在给套囊充气的同时,用指尖按压指示气囊,调节套囊压力,直至指示气囊的触感张力与鼻翼相仿。

干预措施代码:

Intervention:

When using this method, the anesthesiologist inflates the cuff while pressing the pilot balloon with a fingertip to adjust cuff pressure, until the tension of the pilot balloon feels comparable to that of the nasal ala.

Group:

GroupB

Sample size:

干预措施:

通过麻醉机闭合回路监测屏实时观察流量-容积环形态变化。采用分次注气法对套囊进行充气,每次注入0.5 mL气体:若流量-容积环未闭合,则继续注气直至呼气支回归零点并与吸气支交汇形成闭合环,此时测得首次套囊压(P1)。随后以0.2 mL/次梯度回抽套囊气体,直至流量-容积环再次开放(出现漏气),继而以0.2 mL/次梯度重新注气至流量-容积环闭合,测得二次套囊压(P2)。最终两组气管导管套囊压力均由第二位对套囊充气方法采用盲法的研究者使用套囊压力计进行评估。若术中受试者头颈部需重新摆放体位,则根据分组对应方法以0.2 mL气体增量重复套囊充气操作,最终以末次测量值替代P2纳入分析。

干预措施代码:

Intervention:

Observe real-time changes in the flow-volume loop on the monitor of the anesthetic machine’s closed circuit. Inflate the cuff using the fractional air injection method with 0.5 mL of air injected each time. If the flow-volume loop remains open, continue inflation until the expiratory limb returns to the zero point and converges with the inspiratory limb to form a closed loop; record the initial cuff pressure (P?) at this moment. Next, withdraw air from the cuff incrementally at 0.2 mL per time until the flow-volume loop opens again (air leakage occurs). Then reinflate the cuff at the same 0.2 mL increment until the loop is closed once more, and record the secondary cuff pressure (P?). All cuff pressures of the endotracheal tubes were finally measured with a cuff pressure manometer by a second researcher who was blinded to the cuff inflation protocols. If repositioning of the subject’s head and neck was required intraoperatively, repeat the cuff inflation procedure in 0.2 mL increments according to the assigned group method. The last measured value was used to replace P? for statistical analysis.
