Evaluation of bronchoscopic direct vision glottis anesthesia method in bronchoscopy

Area of Science:

• Anesthesiology
• Pulmonology
• Thoracic Surgery

Background:

• Fibrobronchoscopy is a common diagnostic and therapeutic tool for respiratory diseases, requiring anesthesia.
• Existing anesthesia methods like nebulized inhalation have limitations.
• Bronchoscopic direct-vision glottis anesthesia is a novel, simple, and cost-effective technique.

Purpose of the Study:

• To evaluate the effectiveness and safety of bronchoscopic direct-vision glottis anesthesia.
• To compare this method against traditional nebulized inhalation anesthesia for bronchoscopy.

Main Methods:

• A randomized controlled study involving 100 patients undergoing bronchoscopy during thoracic surgery.
• Patients were divided into two groups: nebulized inhalation anesthesia (control) and bronchoscopic direct-vision glottis anesthesia (observation).
• Hemodynamic indices (SBP, DBP, HR, SpO2) and serum stress hormones (NE, E, ACTH, Cortisol) were measured and compared.

Main Results:

• The observation group exhibited significantly lower SBP, DBP, and HR, and higher SpO2 compared to the control group.
• Stress hormone levels (NE, E, ACTH, Cortisol) were significantly lower in the observation group post-treatment.
• The incidence of adverse reactions was lower in the observation group (6%) versus the control group (12%).

Conclusions:

• Bronchoscopic direct-vision glottis anesthesia effectively stabilizes hemodynamic parameters during bronchoscopy.
• This anesthesia method significantly reduces patient stress levels.
• The technique demonstrates good safety and practicality for clinical application.
