local anesthesia Flashcards
case
1) 7 year old mike for first time restoration
2) he is anxious but can manage vaccines
local anesthesia is similar
1) except for different craniofacial anatomy
superior dental plexus
1) posterior, middle, anterior superior branches of maxillary nerve
maxilla
1) thinner
mandible
1) IA nerve
2) thicker
3) bony structure smaller than adults
mandibular foramen location
1) <6 years
- below occlusal plane
2) 6-9
- at the level
2) >9 years
- slightly above
clinical significance of bone density vs maxilla vs mandible
1) infiltration is more successful in maxilla
mandibular ramus is
shorter and narrower anterior-posteriorly
- avoid facial nerve
- you can use 21 mm short needle
armamentatium
1) eye protection
2) molt mouth prop
3) cotton 2x2 gauze
4) needle
5) benzocaine
never bend needle
1) needles can break
2) kids move
3) incorrect administration technique
N2O
1) anxiolytic
2) distorts time passage
3) raises pain threshold
4) 100% oxygen for 5 minutes to prevent diffusion hypoxia
N2O contraindications
1) combative
2) emphysema
3) otitis media
4) nasal obstruction
5) URIs
6) cardiomyopathy
7) severe asthma
8) pregnant women in first trimester
rapid induction
1) deliver 30-50% N2O immediately
2) 100% O2 post op
N2O indications
1) for anxious but cooperative patients
2) long appointments
3) emergency appointments
4) gag reflex
N2O effects
1) tingling
2) floating
3) relaxation, happiness
