Effect of Regulated Pleural Pressure on Air Leak and Fluid Drainage Following Pulmonary Resections: A Multicenter Randomized Trial

Not Applicable

Withdrawn

• Conditions: Lung Cancer
• Interventions: Procedure: Switching level of suction

• Registration Number: NCT02002273
• Lead Sponsor: Ospedali Riuniti Ancona

Brief Summary

The objective of this randomized study is to compare the effect of two controlled chest tube protocols on the duration of air leak and fluid drainage following pulmonary lobectomy or segmentectomy by using an electronic regulated chest drainage system (Thopaz). Previous studies have suggested that the amount of negative pressure used at the level of the chest drainage device may affect the duration of air leak, but the results have been inconsistent, however as revealed in more recent studies understanding of the physics of chest drainage devices may have been confounded by lack of regulation of the pleural pressure.

In addition, experimental studies have shown that fluid drainage may be affected by the degree of negative pleural pressure applied.

Arm && Interventions

Group	Intervention	Description
regulated seal mode (-8 cmH2O).	Switching level of suction	On the morning of each postoperative day (starting with POD#1) patients of group 1 are switched for 4 hours to -8 cm H2O and patients of group 2 are switched to -20 cm H2O. After this period of 4 hours both groups are switched back to their original pressure levels, with the effect on air leak and fluid leak measured. Pts are then left on their original pressure level until the next day, when the switch to -8 or - 20 cm H2O is again made.
Patients with regulated suction mode	Switching level of suction	On the morning of each postoperative day (starting with POD#1) patients of group 1 are switched for 4 hours to -8 cm H2O After this period of 4 hours both groups are switched back to their original pressure levels, with the effect on air leak and fluid leak measured. Pts are then left on their original pressure level until the next day, when the switch to -8 or - 20 cm H2O is again made.
