A new device for evacuating air from the cardiac chambers

Area of Science:

• Cardiovascular Surgery
• Medical Device Innovation
• Anesthesiology

Background:

• Air embolism is a significant risk following cardiopulmonary bypass.
• Current de-airing methods can be time-consuming and less effective.
• Ensuring complete air removal is critical for preventing complications.

Purpose of the Study:

• To introduce and evaluate a new device for complete cardiac de-airing.
• To assess the efficacy of active suction in air removal from the heart.
• To provide a visually verifiable method for confirming successful de-airing.

Main Methods:

• Development of a device with an aspiration needle, transparent bulb, and flutter valve.
• Application of the device for de-airing in adult and pediatric patients.
• Utilizing the device's vacuum-creation mechanism for active air suction.

Main Results:

• The device demonstrated effective removal of air from cardiac chambers.
• Visual confirmation of complete de-airing was possible due to the transparent bulb.
• Successful application in patients with both congenital and acquired heart disease.

Conclusions:

• The new device offers an effective method for complete cardiac de-airing post-cardiopulmonary bypass.
• Active suction and visual assessment enhance the safety and reliability of the de-airing procedure.
• This innovation holds promise for reducing air embolism complications in cardiac surgery.
