Patient-controlled sedation improved selected outcomes under spinal anesthesia, but both groups received remimazolam.
What the source reports
One hundred twenty adults aged at least sixty-five undergoing lower-limb surgery were randomized to patient-controlled or conventional sedation. The patient-controlled arm used a low background infusion with demand boluses. Optimal sedation was reported in 100% versus 88.3%, with lower total consumption and faster recovery in that arm. Comfort and satisfaction also favored patient control.
Limits and uncertainty
Patients and clinicians could not be blinded to the delivery system, although assessors were blinded. Loading and maintenance strategies differed, so patient agency cannot be isolated from the dosing architecture. The single-center population and supervised surgical environment limit broader conclusions.
Implications for forensic review
When evaluating sedation quality, identify whether a study changes the drug, the delivery method or both. These results do not compare remimazolam with another sedative and do not validate unsupervised self-administration. The practical question is how the complete monitored titration system influenced depth, exposure and recovery in the studied setting.
