And which anesthesia effect is good?

• Local anesthetic. Local anesthetic intensity: tetracaine>tetracaine hcl>lidocaine>lidocaine hcl> benzocaine > procaine>procaine hcl 
   
• Tetracaine hcl local anesthetic intensity is 10 times that of procaine, the effect can be maintained for 2 to 3 hours, with strong penetrating power
   
• The local anesthetic effect of benzocaine is weaker than procaine, and it cannot be infiltrated, and the local absorption is slow and long-lasting.
   
• Lidocaine is a local anesthetic, also known as lidocaine, which has replaced procaine in recent years and is widely used in cosmetic plastic surgery for local infiltration anesthesia.
   
• Procaine hydrochloride is a local anesthetic that temporarily blocks the conduction of nerve fibers and has an anesthetic effect. It has a strong effect and low toxicity.
