Study Notes
General Anesthetics and Cardiovascular System
- The primary effect of general anesthetics on the cardiovascular system is a decrease in blood pressure.
- One exception is ketamine, which can increase blood pressure due to increased plasma noradrenaline concentration.
General Anesthetics and Respiration
- Most general anesthetics depress respiration, leading to a decrease in respiratory rate.
- One exception is ketamine, which does not depress respiration.
General Anesthetics and Central Nervous System
- The pharmacological action of general anesthetics on the central nervous system is to depress the nervous system.
Characteristics of General Anesthetics
- Barbiturates are known for causing rapid induction with little or no excitement.
- Halothane is commercially synthesized from a compound.
- Halothane is synthesized from trichloroethylene and bromine.
Effects of Specific General Anesthetics
- Ketamine is an exception in terms of its effect on respiration, as it does not depress respiration.
- Ketamine can increase plasma noradrenaline concentration, leading to an increase in blood pressure.
- Most general anesthetics, except for ketamine, decrease blood pressure.
