General Anesthesia With and Without Remifentanil for Flexible and Rigid Bronchoscopy: A Retrospective Case-Matched Study.

Prior research suggests general anesthesia (GA) with remifentanil is superior to GA without remifentanil regarding perioperative outcomes, including the postanesthesia care unit (PACU) length of stay (LOS). The objective of this study was to compare the intraoperative management and PACU LOS in patients who underwent GA with or without remifentanil for bronchoscopy. The study included 5,763 adult patients who underwent flexible bronchoscopy and received GA with or without remifentanil or who underwent rigid bronchoscopy and received GA with or without remifentanil.
