Inhaled Anesthetics VS Intravenous Anesthetics
Aspect | Inhaled Anesthetics | Intravenous Anesthetics |
Administration | Inhaled through the respiratory system | Administered directly into the bloodstream via IV |
Onset of Action | Slower onset | Rapid |
Control of Depth of Anesthesia | Easier to titrate and adjust | May require continuous monitoring and adjustment |
Elimination | Primarily eliminated via the lungs | Metabolized by the liver and excreted by kidneys |
Reversibility | Reversal agents are limited | Reversal agents are available for some drugs |
Respiratory Effects | May depress respiration | Generally has less impact on respiration |
Cardiovascular Effects | Can cause vasodilation and hypotension | May have variable cardiovascular effects |
Patient Cooperation | Requires patient cooperation | Suitable for patients who may not tolerate inhalation induction |
Advantages | · Precise control of anesthesia depth · Suitable for prolonged procedures · Lower risk of drug accumulation | · Rapid onset and offset of anesthesia · Can be used in patients with respiratory issues |
Disadvantages | · Longer recovery times · May require specialized equipment · Expensive equipment and gases | · Limited control over depth of anesthesia · Risk of drug accumulation and prolonged effects · Possibility of hemodynamic instability · Allergic reactions |
Examples
| · Isoflurane · Sevoflurane · Desflurane | · Propofol · Etomidate · Barbiturates · Ketamine |
