Decline of Halogenated Anesthetics
Decline of Halogenated Anesthetics
Halogenated ethers and hydrocarbons fell out of favor due to the risk of hepatic injury and liver failure.
Anesthetic Enantiomers
Anesthetic Enantiomers
Newer anesthetics have been modified as enantiomers to enhance safety.
Advantage of Enantiomers
Advantage of Enantiomers
Enantiomers can reduce risks by lowering the necessary dose of potent drugs.
