Mechanical Power and Pulmonary Complications in CABG Surgery

Condition(s) studied

Investigational drug(s) / intervention(s)

Intraoperative Mechanical Ventilation Monitoring: Intraoperative ventilatory parameters (tidal volume, respiratory rate, plateau pressure, PEEP) are routinely recorded during CABG surgery. Mechanical power and driving pressure are calculated from these parameters. No additional intervention is applied beyond standard clinical care.

Study summary

This prospective observational study evaluates the association between intraoperative mechanical power (MP) - a composite measure of the total energy delivered to the lungs during mechanical ventilation - and postoperative pulmonary complications (PPCs) and prolonged mechanical ventilation in adult patients undergoing elective coronary artery bypass graft (CABG) surgery with cardiopulmonary bypass (CPB). Intraoperative ventilatory parameters including tidal volume, respiratory rate, airway pressures, and PEEP will be recorded and used to calculate MP and driving pressure (DP). No additional interventions will be applied beyond standard clinical care.

Eligibility

Primary outcome measure(s)

• Postoperative Pulmonary Complication — Within the first 48 hours postoperatively
  Occurrence of at least one of the following within the first 48 hours postoperatively: atelectasis, pleural effusion, pneumonia, prolonged oxygen requirement, need for non-invasive ventilation (NIV), or re-intubation
