This trial is active, not recruiting.

Conditions pulmonary air leak, lobectomy, wedge resection, segmentectomy
Treatments thopaz (digital drainage), pleur evac (analogue drainage)
Sponsor Ottawa Hospital Research Institute
Start date January 2013
End date May 2014
Trial size 176 participants
Trial identifier NCT01775657, 20120228-01H


This study will evaluate the impact of continuous, digital pulmonary air leak monitoring on the duration of pleural drainage after lung resection in patients with and without a pulmonary air leak on postoperative day 1.

Patients undergoing pulmonary resection who fit the inclusion criteria will be identified pre-operatively. Patients within two groups (air leak and no air leak) will be randomized to receive either the analogue system or the digital system. Both systems are approved for use in hospitals by Health Canada. There will be 88 patients in each air leak group.

Hypothesis: Continuous, quantitative monitoring of PAL following lung resection leads to an improvement in primary outcomes.
