An endobronchial cuff indicator for use in thoracic surgery.

Area of Science:

• Anesthesiology
• Respiratory Medicine
• Medical Device Engineering

Background:

• Double-lumen endotracheal tubes (DLTs) are crucial for lung isolation during thoracic surgery.
• Accurate inflation of the bronchial cuff is essential for effective lung separation and to prevent airway injury.
• Inadequate cuff inflation or accidental deflation can lead to complications such as hypoxemia or endobronchial intubation.

Purpose of the Study:

• To describe a simple apparatus for precise bronchial cuff inflation of DLTs.
• To present a method for detecting accidental bronchial cuff collapse.
• To enhance the safety and efficacy of DLT use in clinical practice.

Main Methods:

• Development of a straightforward apparatus for monitoring DLT bronchial cuff pressure.
• Implementation of a method to ascertain the exact end-point during cuff inflation.
• Integration of a detection mechanism for spontaneous cuff deflation.

Main Results:

• The described method allows for the attainment of an exact end-point during bronchial cuff inflation.
• The apparatus successfully detects accidental collapse of the bronchial cuff.
• This provides a reliable means to ensure proper DLT function.

Conclusions:

• The developed apparatus and method offer a simple yet effective solution for managing DLT bronchial cuffs.
• This innovation can improve the reliability of lung isolation and reduce the risk of associated complications.
• It represents a practical advancement in airway management technology.
