Comparison of automated and manual control methods in minimal flow anesthesia
Authors' conclusion
The ACA mode was more advantageous than the MCA mode, reaching target AA concentrations faster and requiring fewer adjustments to achieve a constant depth of anesthesia.
Study context
- Population
- Patients undergoing gynecological surgery
- Participants
- 76 patients
- Comparison
- Automatically controlled anesthesia (ACA) vs MCA
Primary result
As reported in the abstract
Depth of anesthesia, anesthetic agent (AA) consumption, time to target, awakening times, ventilator adjustments
- No statistically significant difference in depth of anesthesia
- No primary endpoint named in the abstract
Further findings
Time to achieve MAC target of 1
| Outcome | ACA | MCA | P value |
|---|---|---|---|
| Anesthetic agent consumptionNo statistically significant difference | 19.1 ± 4.9 ml | 17.2 ± 4.5 | P = 0.076 |
| Number of vaporizer adjustments | 15 | 217 |
Time to achieve minimum alveolar concentration (MAC) target of 1
- ACA mode achieved the MAC target significantly faster
