研究目的:

1. 主要目的:评估在经喉罩置入支气管封堵器进行左侧肺隔离时,辅助使用头偏转法(头转向左侧)是否能显著缩短单肺通气的建立时间。 2. 次要目的:比较头偏转法与标准方法在首次尝试成功率、总尝试次数、技术失败率、术中低氧血症发生率及术后咽喉并发症发生率方面的差异。  

Objectives of Study:

1. Main objective: To evaluate whether the use of head deviation method (turning the head to the left) as an auxiliary measure can significantly shorten the establishment time of single-lung ventilation when performing left lung isolation with the insertion of bronchial occluder through laryngeal mask. 2. Secondary objective: To compare the differences between the head deviation method and the standard method in terms of the success rate of the first attempt, the total number of attempts, the failure rate of the technique, the incidence of intraoperative hypoxemia, and the incidence of postoperative throat complications.

Group:

Head Rotation Group

Sample size:

干预措施:

经喉罩置入封堵器时,助手将患者头部轻柔向左旋转约 60° ,操作者在纤支镜直视下直接推送封堵器。

干预措施代码:

Intervention:

During insertion of the bronchial blocker through the laryngeal mask airway, an assistant gently rotated the patient's head leftward by approximately 60°, while the operator advanced the blocker directly under direct visualization with a fiberoptic bronchoscope.

Sample size:

干预措施:

头部正中位。操作者在纤支镜直视下,于隆突上调整封堵 器方向后推送。

干预措施代码:

Intervention:

The head is in the neutral position. The operator, under the direct vision of the bronchoscope, adjusts the direction of the occluder on the hilum and then pushes it forward.

随机方法(请说明由何人用什么方法产生随机序列):

由不参与本研究的一名研究人员(统计学负责人)使用计算机生成的随机数字表,采用区组随机法(区组大小为4)产生随机序列。随机序列以密封不透明信封保存,由麻醉诱导前的巡回护士开启并告知操作医生分组结果。

Randomization Procedure (please state who generates the random number sequence and by what method):

The randomization sequence was generated by an independent statistician who was not involved in patient enrollment or outcome assessment, using a computer-generated random number table with a block design (block size of 4). The allocation sequence was concealed in sealed opaque envelopes. A circulating nurse opened the envelope and revealed the group assignment to the operating anesthesiologist just before induction of anesthesia.
