This study investigated the incidence of bronchial blocker malposition in the lateral versus supine position and evaluated the effectiveness of lateral placement.
Routine thoracic surgery anesthesia requires that endotracheal intubation be performed with the patient in the supine position; the patient subsequently needs to be placed in a lateral position through the cooperation of the anesthetist, theatre nurse, and surgeon. Achieving this change in position is time-consuming and likely to result in adverse events, such as loss of the anesthetic airway and arteriovenous catheter, hemodynamic fluctuations, and malposition of the BB which adversely affect anesthesia management and postoperative recovery. For patients with hypertensive heart disease, the risk of cardiovascular and cerebrovascular accidents increases during the perioperative period .
Therefore, we conducted a prospective, randomized, controlled, multi-center study to evaluate the ease, efficacy, and safety of video laryngoscopy-guided intubation and bronchial blocker placement performed in lateral position.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intubation and bronchial blocker placement performed in lateral position | Experimental | In the lateral position group, patients were positioned laterally (as required for surgery) before anesthesia induction. After anesthesia induction, both endotracheal intubation and bronchial blocker placement were performed while the patient remained in the lateral position. |
|
| Intubation and bronchial blocker placement performed in supine position | No Intervention | Intubation and the placement of a bronchial blocker are typically carried out with the patient in the supine position, which is a standard procedure in thoracic surgery. |
