Study Notes
Inhalation Sedation
- Definition: A technique using drugs that depress the central nervous system to allow for treatment while maintaining verbal contact with the patient. Aims to avoid loss of consciousness.
-
History:
- 1771-72: Joseph Priestley discovered oxygen and nitrous oxide (N2O).
- 1778: Humphrey Davy relieved his pericoronitis pain using N2O.
- 1799: Public demonstrations of N2O effects.
- 1844: Horace Wells used N2O in dentistry.
- 1845: Public demonstrations of N2O use in dentistry.
-
Evidence of Success:
- Useful alternative to general anesthesia (GA), but patient selection is crucial.
- Can improve cooperation and confidence when used with behavioral management/semi-hypnotic suggestion.
- Cost-effective alternative to GA, but more expensive than local anesthesia (LA) alone.
- Successful treatment of 221 out of 265 children needing extractions (Blain & Hill 1998).
- Success rates quoted between 83-97% (Blain & Lyrazopoulos 2003).
- Preferred to GA for anxious children needing elective orthodontic extractions (BSPD Guidelines 2002, Shepherd & Hill 2000).
- Less post-operative distress in children undergoing extraction with inhalation sedation compared to GA (Arch et al 2001).
- Cochrane Review showed positive behavioral changes with N2O use.
- Assume all patients have fear and anxiety.
-
Indications:
- Mild to moderate anxiety.
- Needle phobia.
- When profound LA can't be achieved (e.g., acute pulpitis).
- Prominent gag reflex.
- Prolonged or unpleasant procedures (e.g., surgical extractions).
- Hypoplastic teeth to reduce sensitivity.
- Alternative to GA for specific needs/medically compromised patients.
- Emergency treatment (dental trauma, but not maxillofacial injuries).
-
Contraindications:
- Balance the risks of sedation against the risks of GA.
- Consult the patient's doctor or specialist if unsure.
- Inability to communicate effectively.
-
Terminology:
- Relative Analgesia: A term used to describe inhalation sedation.
- Conscious Sedation: The current preferred terminology by the European Federation for the Advancement of Anaesthesia in Dentistry ( EFAAD).
