Local anesthesia > Topical anesthesia(表面麻醉) > Local Infiltration(局部浸润麻醉) small area anesthetized (one or two teeth) solution deposited near terminal nerve endings ○ 2 extractions > Nerve block(阻滞麻醉) REVIEW deposited near large nerve trucks 2021/221
2021/2/21 Local Anesthesia REVIEW ➢ Topical Anesthesia(表面麻醉) ➢ Local Infiltration( 局部浸润麻醉) • small area anesthetized (one or two teeth) • solution deposited near terminal nerve endings • 8 8 , 2 2 extractions ➢ Nerve Block ( 阻滞麻醉) • deposited near large nerve trucks
Advantages of nerve block Larger analgesia area avoid several injections Less dosage long-lasting Away from the lesion --avoid spreading of infection tumor seeding Less tissue deformity post-injection-- plastic surgery Better Anesthetic Effectiveness 2021/221
2021/2/21 Advantages of nerve block ➢ Larger analgesia area & avoid several injections ➢ Less dosage & long--lasting ➢ Away from the lesion -- avoid spreading of infection & tumor seeding ➢ Less tissue deformity post-injection -- plastic surgery ➢ Better Anesthetic Effectiveness
