Clinical Trial Summary

The purpose of this study is to investigate whether the use of inhaled anesthetics, compared to intravenous anesthetics, can affect the amount of lung inflammation and postoperative respiratory complications seen after cardiac surgery.


Description:

Randomized, controlled trial involving 45 adult patients undergoing cardiac surgery with cardiopulmonary bypass. Patients will be randomized to receive either inhaled anesthesia with sevoflurane or total intravenous anesthesia (TIVA) with propofol for the maintenance phase of their cardiac anesthetic. Assessment of lung inflammation will take place using fiberoptic bronchoscopic sampling of lung fluid as well as serum collection before and after exposure to cardiopulmonary bypass, and the incidence of compositive postoperative pulmonary complications will take place in the postoperative period.

Outcome

Type Measure Description Time frame Safety issue
Primary Bronchoalveolar Lavage (BAL) Concentration of TNF Alpha (pg/mL) Inflammatory mediator found in BAL fluid during lung inflammation Change from baseline and 2-4 hours after exposure to cardiopulmonary bypass
Secondary Number of Patients With Postoperative Pulmonary Complications Composite endpoint of clinically relevant pulmonary complications Assessed daily, beginning on the first day after surgery, until hospital discharge or death. On average at our institution, most patients are discharged within 7 days so this is the expected time frame for follow up.
Secondary BAL Concentration of IL1b (pg/mL) Inflammatory mediator found in BAL fluid during lung inflammation Change from baseline and 2-4 hours after exposure to cardiopulmonary bypass
Secondary BAL Concentration of IL6 (pg/mL) Inflammatory mediator found in BAL fluid during lung inflammation Change from baseline and 2-4 hours after exposure to cardiopulmonary bypass
Secondary BAL Concentration of IL8 (pg/mL) Inflammatory mediator found in BAL fluid during lung inflammation Change from baseline and 2-4 hours after exposure to cardiopulmonary bypass
Secondary BAL Concentration of MCP1 (pg/mL) Inflammatory mediator found in BAL fluid during lung inflammation Change from baseline and 2-4 hours after exposure to cardiopulmonary bypass
Secondary BAL Concentration of sRAGE (pg/mL) Biomarker of lung injury (RAGE - receptor for advance glycosylation end products) Change from baseline and 2-4 hours after exposure to cardiopulmonary bypass
