The study compared induction choices while maintaining the same volatile anesthetic afterward, in patients who continued their angiotensin-receptor blocker.
Study findings
The randomized prostatectomy study included 112 hypertensive patients taking ARBs. Remimazolam or propofol was used for induction, followed by sevoflurane maintenance in both groups. Hypotension across anesthesia occurred in approximately 89.3% and 87.5%, respectively, without a clear difference. Severity measures, vasopressor use and the initial fifteen-minute analysis also did not show a clear advantage.
What limits the conclusion
The induction doses and delivery methods were specific, including bolus remimazolam and a relatively low propofol dose. This was not a comparison of remimazolam-only versus propofol-only maintenance. Nor did it randomize patients to continue or withhold an ARB, so it cannot determine the best preoperative ARB policy.
Implications for case review
For an anesthesia-related blood-pressure opinion, separate chronic medication management, induction, maintenance and operative conditions. A general statement that one sedative preserves pressure should not replace the result in this population. The trial does not establish that either induction agent prevents hypotension when an ARB is continued. Actual baseline pressure, measurement frequency, positioning, fluid treatment and vasopressor response are needed to interpret an individual episode.
