DESFLURANE vs KETALAR
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.
Noncompetitive NMDA receptor antagonist; inhibits glutamate activity, modulates opioid receptors, and interacts with other neurotransmitter systems.
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).
1-4.5 mg/kg IV or 6.5-13 mg/kg IM for induction of anesthesia; 0.1-0.5 mg/kg/min IV infusion for maintenance.

Clinical Note
moderateDesflurane + Bumetanide
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: 2.5-3 hours (ketamine); norketamine: 12 hours. Clinical context: Short half-life facilitates rapid recovery, but context-sensitive half-life increases with infusion duration.
Primarily eliminated via exhalation; minimal hepatic metabolism (<0.02%). Renal excretion of metabolites negligible. >99% excreted unchanged by lungs.
Renal: 90% as metabolites (norketamine, dehydronorketamine); unchanged: 2-4%. Fecal: <3%.
