Research Summary:

Title: Digital air leak monitoring for patients undergoing anatomical lung resection: a randomized controlled clinical trial

Air leak is the most significant complication following lung resection resulting in delayed discharge from hospital. The incidence of prolonged air leaks is 5-25%. Multiple trials have shown favorable outcomes with the use of digital air leak recording. The majority of previous trials are limited by small sample sizes, heterogeneity in the type of lung resections and lack of follow-up. The study is a single centre randomized controlled trial at the Victoria General Hospital of the NSHA in Halifax, NS. A comparison of the use of digital and analog chest tube devices in patients undergoing anatomical lung resection was completed. 215 patients underwent randomization immediately after surgery.

Results: There was no significant difference in outcomes for length of hospital stay (p=0.211), chest tube duration (p=0.141) and number of CXR performed (p=0.299). There was also no difference in post-chest tube removal pneumothorax (p=0.279) or need for chest tube re-insertion (p=0.294). The only significant finding was that of a higher number of patients having their chest tube clamped prior to removal, 47% in the non-digital group and 18% in the digital group (p<0.001).

Conclusions: Digital devices did not result in reduced chest tube duration or hospital length of stay.
