Perioperative pain and addiction interdisciplinary network (PAIN): protocol for the perioperative management of cannabis and cannabinoid-based medicines using a modified Delphi process.

Introduction: At the conception of this study (January 2019), a literature search by the authors found no evidence-based or consensus perioperative guidelines for patients consuming cannabis products, or for those patients in whom a cannabinoid medication could be considered for perioperative treatment. Currently, there is a large global population that consumes cannabis. The availability of cannabis has also increased this decade with greater legal access to cannabis products in some countries such as USA, Canada, Uruguay, Israel, Australia and Germany.

Effect of aortic pericardial valve choice on outcomes and left ventricular mass regression in patients with left ventricular hypertrophy.

Objectives: We sought to assess the effect of 2 contemporary pericardial valves on left ventricular mass regression and clinical outcomes after aortic valve replacement (AVR) in patients with aortic stenosis (AS).

Methods: Patients were followed postoperatively in a dedicated valve clinic. A propensity score was derived for each patient and used to adjust all analyses.

Clinical and mechanical factors associated with the removal of temporary epicardial pacemaker wires after cardiac surgery.

Background: Temporary pacemaker wires are placed in the majority of patients after cardiac surgery. There is no information on mechanical factors related to wire removal.

Methods: Clinical information related to temporary wire use and removal was prospectively collected from a large cardiac surgical unit over one year.

Clinical Correlation of Early Atelectasis after Bilateral Internal Thoracic Artery Harvest for Coronary Artery Bypass Grafting.

Background: Atelectasis is a significant complication after cardiac surgery. The current study was designed to assess the significance of atelectasis after bilateral internal thoracic artery (BITA) harvest.

Methods: The ICU admission chest x-ray of 565 patients undergoing BITA was reviewed.
