DESFLURANE vs PROPOFOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Desflurane is a volatile general anesthetic that potentiates inhibitory GABA and glycine neurotransmission and inhibits excitatory NMDA glutamate receptors, leading to neuronal hyperpolarization and reduced neuronal excitability.
Propofol enhances the activity of gamma-aminobutyric acid (GABA) at GABA-A receptors, leading to increased chloride conductance, neuronal hyperpolarization, and anesthetic effects. It also inhibits N-methyl-D-aspartate (NMDA) receptors and modulates calcium influx via L-type calcium channels.
Induction: 3-12% inhaled, titrated to effect; maintenance: 2-6% inhaled, adjusted to maintain adequate anesthetic depth with up to 1 MAC (6.0% at 37°C, 1 atm).
Induction: 2-2.5 mg/kg IV bolus. Maintenance: 25-75 mcg/kg/min IV infusion. For sedation: 25-100 mcg/kg/min IV.

Clinical Note

Terminal elimination half-life is 3.5–4.5 minutes (context-sensitive half-life after prolonged anesthesia can be longer due to distribution, but true elimination is rapid due to low blood/gas partition coefficient).
Terminal elimination half-life: 4-7 hours (after prolonged infusion, context-sensitive half-life increases up to 60 minutes after 8-hour infusion).
Primarily eliminated via exhalation; minimal hepatic metabolism (<0.02%). Renal excretion of metabolites negligible. >99% excreted unchanged by lungs.
Renal: <1% unchanged; hepatic metabolism to inactive glucuronide and sulfate conjugates, excreted renally (≈88%) and fecally (≈1-2%).
