Correlation between spinal anesthetic EC50 of the four emulsified volatile anesthetics and their MAC × olive oil/gas partition coefficients
| λ | MAC in rats (% ) | MAC × λ | Spinal EC50 (mol/L) | |
|---|---|---|---|---|
| Halothane | 224.0 ± 9.0 | 1.24 | 277.76 | 0.35 |
| Isoflurane | 88.2 ± 1.3 | 1.45 | 127.89 | 0.27 |
| Enflurane | 103.0 ± 4.0 | 2.20 | 226.6 | 0.33 |
| Sevoflurane | 47.5 ± 0.8 | 2.80 | 133.0 | 0.26 |
λ: olive oil/gas partition coefficient; All the data of inhaled MAC and olive oil/gas partition coefficients in this table were from the study by Taheri S et al. [12].
