Abstract

<p>SB Leak Checker® is a newly developed device to quantitatively measure air leakage after thoracic surgery. SB Leak Checker® is connected to the conventional drainage system, which enables visual evaluation of air leakage. We conducted a clinical trial to evaluate the effectiveness of SB Leak Checker®.</p><p>SB Leak Checker® was used in thoracic surgeries performed at our hospital for 12 patients. SB Leak Checker® values and visual air leakage were observed. Drains were removed as before by the clamp test.</p><p>The amount of air leakage measured by SB Leak Checker® was −76~9 mL/min for no air leakage, −7~84 mL/min for air leakage on coughing, 91~540 mL/min for air leakage on expiration, and 326~1327 mL/min for air leakage on both expiration and inspiration. There was no clear discrepancy between the visual confirmation of air leakage and SB Leak Checker® value. No adverse events were observed.</p><p>SB Leak Checker® can be used safely and is considered useful for judging whether a drain can be removed.</p>
