What anesthetic techniques are commonly used for CABG surgery?
Historically, the popularity of several anesthetic techniques for CABG has varied on the basis of their known or potential adverse cardiovascular effects (eg, cardiovascular depression with high doses of volatile anesthesia, lack of such depression with high-dose opioids, or coronary vasodilation and concern for a steal phenomenon with isoflurane) as well as concerns about interactions with preoperative medications (eg, cardiovascular depression with beta blockers or hypotension with angiotensin- converting enzyme [ACE] inhibitors and angiotensin-receptor blockers [ARBs]28 30).
