Dear student,

● Answer -

(b) halothane

◆ Halothane -

• Halothane is a highly volatile general anesthetic.
• It is administered by inhalational route.
• It is used for induction & maintainance of anesthesia.
• Total hepatic blood flow is decreased because of decreased cardiac output.
• Halothane decreases both portal blood flow & hepatic artery blood flow.
• It stops the autoregulatory mechanism of liver.
