Sedação profunda com intubação endotraqueal preventiva para procedimentos avançados de broncoscopia
Um estudo prospectivo observacional sobre a segurança e viabilidade da sedação profunda sob a direção processualista com intubação endotraqueal preventiva para procedimentos avançados de broncoscopia
Bronchoscopy is crucial for diagnosing and treating respiratory diseases and is recommended under sedation. Deep sedation improves patient comfort and procedural efficiency, especially in complex cases, by reducing movement and coughing. However, it carries risks of respiratory depression and airway obstruction, potentially requiring premature termination or urgent intubation. Determining the optimal timing for intubation can be challenging despite proper monitoring. To enhance safety, the investigator has performed bronchoscopy under deep sedation with preemptive intubation for years, sharing this experience with other hospitals. This study aims to evaluate its safety and feasibility through a multicenter prospective observational approach.

Descrição detalhada
Bronchoscopy is a crucial procedure for diagnosing and treating respiratory diseases. It is recommended to be performed under sedation whenever possible, with sedation levels ranging from minimal to moderate and deep sedation. Deep sedation enhances patient comfort and facilitates the procedure, making it particularly useful for lengthy or complex bronchoscopic examinations. Additionally, deep sedation reduces involuntary patient movements and coughing, allowing the proceduralist to perform bronchoscopy more effectively when the patient is deeply sedated.
Despite its benefits, deep sedation carries the risk of respiratory depression and impaired airway maintenance, which may necessitate early termination of the bronchoscopy. If respiratory suppression or inadequate airway maintenance occurs during deep sedation, the procedure may need to be interrupted for endotracheal intubation using the bronchoscope. However, even with appropriate monitoring during bronchoscopy, determining the optimal timing for endotracheal intubation can be challenging, potentially disrupting procedural continuity and reducing the likelihood of a successful examination.
To enhance patient comfort and procedural safety, the investigator has been performing bronchoscopy under deep sedation with preemptive endotracheal intubation for several years. This clinical experience has been shared with other university hospitals in the region, and cases of deep sedation with preemptive intubation under the supervision of bronchoscopists have been reported. This study aims to evaluate the safety and feasibility of deep sedation with preemptive endotracheal intubation during bronchoscopy through a multicenter prospective observational approach.

If an eligible subject consents to participate in the study, deep sedation and preemptive endotracheal intubation will be performed, followed by bronchoscopy. Deep sedation will be administered according to the study protocol, with final approval of sedative administration given by the proceduralist. Oxygen will be supplied at a flow rate of 4-6 L/min via a nasal cannula before sedative administration. To achieve a deep sedation state (Modified Observer's Assessment of Alertness/Sedation [MOAA/S] score ≤ 2, defined as the patient not opening their eyes despite repeated verbal stimuli), an initial dose of 50 mcg fentanyl will be administered, followed by 2.5-5 mg of remimazolam. The sedation depth will be assessed every two minutes using the MOAA/S score. If the patient has not reached deep sedation, an additional 2.5 mg of remimazolam will be administered. Once deep sedation is achieved, lidocaine will be sprayed onto the trachea and bronchi using a bronchoscope for local anesthe |

Medidas de resultados primários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
The incidence of hypoxia during deep sedation under proceduralist guidance with endotracheal intubation
Prazo: On the day of the bronchoscopy procedure, from the initiation of sedation therapy to the completion of the bronchoscopy procedure.
|
This study investigates the incidence of hypoxia during deep sedation under the proceduralist's guidance with endotracheal intubation. Hypoxia is defined as an oxygen saturation of less than 94% sustained for more than 10 seconds during the procedure. |
On the day of the bronchoscopy procedure, from the initiation of sedation therapy to the completion of the bronchoscopy procedure.

The incidence of severe hypoxia during deep sedation under proceduralist guidance with endotracheal intubation
Prazo: On the day of the bronchoscopy procedure, from the initiation of sedation therapy to the completion of the bronchoscopy procedure.
|
This study investigates the incidence of hypoxia during deep sedation under the proceduralist's guidance with endotracheal intubation. Hypoxia is defined as an oxygen saturation of less than 90% sustained for more than 60 seconds during the procedure. |
On the day of the bronchoscopy procedure, from the initiation of sedation therapy to the completion of the bronchoscopy procedure.
|
|
The incidence of complications
Prazo: From the day of the bronchoscopy procedure to the outpatient visit one week after the procedure.
|
early termination or delay of the procedure, complications from endotracheal intubation, complications from bronchoscopy |
From the day of the bronchoscopy procedure to the outpatient visit one week after the procedure.
|
|
The rate of patient satisfaction
Prazo: From the completion of the bronchoscopy procedure to the point when the patient has fully recovered from sedation.
|
Patient satisfaction immediately after the procedure is assessed by two items: distress during fiberoptic bronchoscopy (distress/ tolerable/ no distress or satisfied) and willingness to be reexamined (accept/ never again). |
From the completion of the bronchoscopy procedure to the point when the patient has fully recovered from sedation.
