What does a higher percentage of anesthesia strength indicate?

• A. Higherdose of active drug per 100 units
• B. Longer duration of action
• C. Less risk of side effects
• D. Faster onset of action

Answer: (A)

A higher percentage of anesthesia strength indicates a higher dose of the active drug per 100 units. This is because the percentage strength of an anesthetic solution reflects the concentration of the active drug in that solution. For instance, a higher percentage means that there is a greater proportion of the anesthetic agent, which corresponds to a higher total dose being administered when calculated in terms of volume. Consequently, this can lead to a more potent effect for the patient, as a stronger concentration of active drug typically produces a more pronounced anesthetic outcome.

While other factors such as duration of action, side effects, and onset of action can be influenced by various properties of the anesthetic, they are not directly indicated by the percentage strength alone. Understanding the implications of the concentration is crucial for administering anesthesia effectively and safely, particularly in phlebology and other medical fields where precise dosing is essential.
