25
Analgesics used in paediatric dentistry
Paracetamol | Ibuprofen
26
Calculating dose of analgesics
Dose by age | Consider weight/height of patient - if lower/higher than ideal for age then consider different dose
27
Contraindications for ibuprofen in children
Asthma, liver disease, renal failure and bleeding disorder
28
What do you have to consider when calculating dose of LA
- Age, weight and height | - Type of LA (2% of 4%)
29
Correct use of topical LA
Apply to dry mucosa in a localised area | Leave for 5 mins until mucosa wrinkled
30
What is an intrapupillary injection
Anaesthesia of the papilla used to prevent painful palatal infiltration
31
What is the "chasing technique"
After buccal infiltration, pass needle to papilla and follow into palatal tissue
32
When are intraligamental infiltrations required
- To supplement infiltrations (or blocks) - Eliminates need for a block - In permanent teeth only
33
Where to approach for an ID blocks in children
From contralateral primary molars
34
Where to approach for a mental block in children
Advance needle in buccal sulcus between apices of 1st and 2nd primary molars
35
What are the COMMON complications of LA
- Failure, bleeding, pain - Psychogenic (syncope, hyperventilation, nausea, palpitations, mimicking allergy) - Lip biting and soft tissue trauma - Toxicity from overdose
36
What are the RARE complications of LA
Allergy Drug interactions Methomoglobineamia Paraesthesia
37
What are the signs of toxicity from LA overdose
- Pt initially appears sedated - slurred speech, altered mood, diplopia and disorientated - High blood pressure can cause tremor, respiratory depression and seizure
38
What are the severe effects of toxicity from LA overdose
Coma, respiratory arrest and cardiovascular collapse
39
What is methemoglobinemia and what LA is usually associated?
- (congenital or acquired) blood condition where RBC contain >1% methemoglobin - Prilocaine, articaine and benzocaine
40
What LA is paraesthesia associated with
Articaine and prilocaine
41
What are the categories of anxiety management in dentistry
Behaviour management Behaviour therapy Conscious sedation General anaesthesia
42
Define conscious sedation
Technique that produces a state of central nervous system depression to enable treatment to be delivered where verbal contact is maintained with the pt throughout.
43
What features are retained in a consciously sedated patient
Verbal communication | Protective reflexes allowing a stable patent airway
44
Aims of conscious sedation
Prevent/reduce dental fear, anxiety or pain Facilitate pt cooperation Promote positive attitude Safe provision and completion of care with minimal disruptive behaviour
45
List examples of conscious sedation
- Inhalation sedation - Oral sedation - Transmucosal (nasal) - Intravenous sedation
46
Indications for conscious sedation (in peadiatrics specifically - so we are thinking of IHS)
- Dental phobia or anxiety - Manage gag reflex - Special care requirements e.g. medically compromised or behavioural conditions - Traumatic or prolonged tx
47
Contraindications for conscious sedation in children
- URT issues - Blocked nose/nasal obstruction - Pre-cooperative children - Medical contraindications - Pt unable to communicate well e.g. some behavioural conditions
48
MH contraindications for inhalation sedation
- Nasal obstruction or congestion - Severe respiratory disease - Middle ear infections - Neuromuscular disorders - Methotrexate - Porphyria - Chemo
49
What is used in inhalation sedation
Titrated dose of nitrous oxide in oxygen
50
Pharmacology of nitrous oxide
- Colourless and almost odourless - Relatively insoluble - Excreted rapidly by lungs
51
Effects of nitrous oxide on the body
- Eurphoria and CNS depressant (sedative) - Mild analgesic - Minimal effect on respiratory system - Minor decr in cardiac output - Slight increase in peripheral resistance
52
Nitrous oxide mode of action
- Analgesic - acting on opiod receptors - Anxiolytic - acts on GABAA receptors - Anaesthetic effect - acts on GABA receptors
53
What is required at the pre-operative assessment for IHS
- Full asessment to confirm the need for sedation - Written consent from parent/pt - Pre and post op instructions - Height and weight
54
What are the pre-op checks before IHS is administered
- Check pt ate or if they need glucose - Check for nasal obstruction - Confirm MH - If consent not taken, achieve now - Record any pre-op analgesia
55
What are the increments nitrous oxide is increased by
5-10%
56
What gas is used at the end of the session
100% oxygen for 3-5 mins
57
Why is 100% oxygen used at the end of the session
Prevent diffusion hypoxia
58
What is recorded post-operatively
- Mask size - Flow rate - % of N2O and oxygen - Time started and finished - Type/amount LA given - Dental treatment provided - Recovery, post op medication and discharge
59
What are the signs of ideal sedation
- Slightly incr bp and heart rate (initially) - Normal, smooth respirations - Flushing of extremities and face - Muscle relaxation
60
Symptoms of ideal sedation
- Lightheadedness - Tingling/numbing of hands and feet - Warm wave or vibrations - Numb oral soft tissues - Euphoric feeling
61
Why may IHS fail?
- Pt not breathing through nose - Ineffective seal around nosepiece - Pt too anxious and cannot cooperate - Fault in machine
62
What are the advantages of INHS
- Non-invasive - good for needle phobic - Titrated dose that can be altered - Rapidly absorbed and excreted - Reflexes maintained - Some analgesic effect - Cost effective and safer than GA
63
What is the onset of IHS
2-3 mins
64
How long does it take for recovery after IHS
Complete recovery within 5 mins
65
Disadvantages of IHS
- Lack of potency - Requires psychological reassurance - Nasal mask may impeded access of upper anteriors - Nitrous oxide pollution - LA still required - Potential adverse effects
66
What are the adverse effects of IHS
- headache, nausea and vomiting | - Loss of consciousness
67
What are the occupational adverse effects due to chronic exposure
- Impaired RBC production and pernicious anaemia | - Avoid in first trimester and preg staff should opt out
68
What is the maximum conc of N2O exposure in 8 hours
100ppm
69
How to minimise N2O pollution
- Active scavenging systems - Good ventilation - Floor level extractor fans - Good technique with pt - Check equipment regularly
