W12: Spectrum of Pain Control Flashcards
List all methods of the Spectrum of Pain and Anxiety Control. Point out which method should be involved every procedure.
Define/compare Anxiolysis, Sedation and Hypnosis
- Anxiolysis – “dissolving anxiety” - Anxiety affects pain perception therefore anxiolytics may be avaluable adjunct to pain control
- Sedation – “state of relaxation or sleepiness”
- Hypnosis – inducing sleep
These drugs are all CNS depressants and also cause muscle relaxation. Action is dose dependent
What is a ‘Phobia’, more specifically the symptoms/signs
Mental health diagnosis criteria
Describe a tool that can be used to measure a patients anxiety. What score indicates a possible phobia?
Questionnaire
ach item scored as follows:
Not anxious = 1
Slightly anxious = 2
Fairly anxious = 3
Very anxious = 4
Extremely anxious = 5
Total score is a sum of all five items, range 5 to 25: Cut off is 19 or above which indicates a highly dentally anxious patient, possibly dentally phobic
List some Basic Patient Psychological/Behavioural management techniques
- Relaxation
- Cognitive rehearsal
- Distraction
- Modelling (watch other person go through process)
- De-sensitization (one step at a time/appt.)
- Hypnosis
Describe the risks of Local Anaesthesia
- Overdose (CNS effect that usually manifests as seizures)
- Trauma (during the procedure (facial nerve palsy) or post-op (lip biting ect.))
- Psychogenic (syncope) - faint
- Incorrect technique (ex, trismus)
- Equipment failure (needle fracture)
List some common pre-medication options
Describe the top 3 pre medication Pharmacokinetics - include dosage
Describe the 4 levels of Sedation
What is Nitrous oxide?
Characteristics
Sweet smelling, non-irritant colourless gasm, Naturally occuring, Weak anaesthetic, Low blood gas solubility, Drug of Abuse,
List the 4 Effects of Inhalation Sedation
- Sedation (side effect)
- Anxiolysis (GOAL)
- Mood alteration
- Analgesia
Describe the MOA/Pharmacodynamics of N2O
Potency of a drug is measured by ‘Minimum Alveolar Concentration (MAC)’. Define.
Potency: Alveolar concentration needed to prevent movement in 50% of patients in response to pain
Example: Low potency (High MAC = low potency) - MAC Inversly proportinate to potency
N2O: Weak anaesthetic MAC = 104 (%)
List the indications for Nitrous Oxide sedation
List the contraindications of Nitrous Oxide sedation
How do you minimise N2O pollution
