Vasoconstrictor preservatives
- Sodium bisulfite
- Metabisulfite
- Acetone sodium bisulfite
Purposes of acetone sodium bisulfite
provides a prolonged shelf life via antioxidant properties.
Disadvantages of acetone sodium bisulfite
- Increased acidity of pH of anesthetic solution
- Potential for allergic reactions
Which anesthetic Agents are metabolized in the plasma by plasma cholinesterase?
Esters
Which anesthetic Agents is metabolized in the liver?
Amides
Short-acting anesthetics
- Approximately 30-minute duration
- Pulpal anesthesia
- No vasoconstrictor
Intermediate-acting Anesthetics
- Approximately 60-minute duration
- Pulpal anesthesia
- Does contain a vasoconstrictor
Long-acting anesthetics
- Approximately 90-minute duration
- Pulpal anesthesia
- Does contain a vasoconstrictor
When hemostasis control is needed
adrenergic vasoconstrictors offer considerable value to the selection of the anesthetic.
Higher doses of epinephrine are needed to produce
the vasoconstriction action of alpha receptors.
Procaine
- Ester of para-aminobenzoic acid (PABA)
- No longer used in dentistry
- Used in medicine as an antiarrhythmic agent
