- Informed consent
- Benefits + risks
- Treatment to be performed
- Practitioner’s experience
What pharmacological agents are available for behavioural management?
- LA
- Nitrous
- Oral sedation
- IV sedation
- GA
Can sedation substitute for LA for pain management?
No
What is the most important management objective?
- Removal of pain, if can not manage pain then can not do treatment
- Remember if child can not handle local likely can’t handle drill
What should be considred in treatment planning LA?
- No medical contraindications
- Maximum allowable dose
- Previous pt history with LA
- Pros and cons of most affected vs least affected first
- Pros and cons of block vs infiltration first appointment
- Need for pharmacological behaviour
T or F? Infiltrations are less traumatising than blocks for children?
F
Children normally can’t tell the difference between the two, generally fine with both or freak out with both
What is the maximum dose of LA recommended for kids?
4.4mg/kg
How much should a 5-6 year old weigh on average?
How many carpules can you use on them?
20kg
4.4mg * 20 = 88 mg maximum dose
One cartridge contains 44mg of LA
Hence 88/44=2 carpules maximum
If 0.1g of topical applied, this adds another 5mg of dosage, thus 88-5=83; 83/44= 1.8 carpules
If you have given one carpule of lignocaine, and your tutor has given the second and neither has worked, what can you do?
Top up with articaine, using different agents can avoid overdose of a single agent
What are some complications involved with using LA?
- Lip and cheek biting
- Overdose (via intravascular injection or excessive dose)
What are some signs of overdose?
CNS depression
Seizures
Disorientation
Loss of consciousness
Decreased CO, CV collapse
What is the maximum dosage of articane?
7mg/kg
How many carpules can be adminstered in a 5-6 year old?
5-6 year old=20kg
Max dose = 7 * 20 = 140mg
Max carpules= 1.5 (for some reason)
What is a contra-indication of articaine for use in children?
Can not use in children under 4 years
