Is intraoperative transit-time flow measurement altered in venous bypass grafts covered by the eSVS mesh?
The eSVS Mesh does not interfere with Doppler flow measurement in covered coronary vein grafts.
Applying suction to the underwater seal drains following lung surgery makes no difference in terms of air leak duration. In the light of this finding we have adopted a uniform policy of no suction being applied to the underwater seal, from the time of surgery, unless a specific clinical judgment is made to use it. The anticipated gains are that this will reduce work and cost and aid mobilization.
