This multicenter, randomized controlled trial compared two intrathoracic pressure settings (−8 cmH₂O vs. −15 cmH₂O) in digital pleural drainage for patients with moderate air leaks after lung resection. No significant differences were found in prolonged air leak rates, air leak duration, chest tube duration, or hospital stay between groups. The…

This randomized study compared standard suction (−20 cmH₂O) and low suction (−8 cmH₂O) using digital drainage after minimally invasive lung resection. Both approaches, with a single 24 Fr Blake drain and a removal threshold of 450 mL/24 h, were safe and effective. However, low suction did not shorten air leak…
