Dental Management of Patients with Obstructive sleep apnoea (OSA)
Important — second opinion only. DentiCision provides an evidence-based second opinion to assist the dentist.

Obstructive sleep apnoea — avoid sedative & opioid stacking
OSA increases the risk of airway obstruction and respiratory depression with benzodiazepines, opioids and gabapentinoids.
Emergency vs routine management
If EMERGENCY — what to do
- • Do not delay emergency treatment — proceed with urgent care while applying the modifications listed above.Ref: American Society of Anesthesiologists — Practice Guidelines for the Perioperative Management of Patients with Obstructive Sleep Apnea. Anesthesiology 2014;120:268–286
If ROUTINE — what to do
- • Proceed with routine care once the listed precautions, labs or timing checks are satisfied.Ref: American Society of Anesthesiologists — Practice Guidelines for the Perioperative Management of Patients with Obstructive Sleep Apnea. Anesthesiology 2014;120:268–286
- • Book at the most suitable time and keep appointments short where advised.Ref: American Society of Anesthesiologists — Practice Guidelines for the Perioperative Management of Patients with Obstructive Sleep Apnea. Anesthesiology 2014;120:268–286
Clinical precautions
- • Prefer local anaesthesia alone; nitrous oxide inhalation sedation is the safest option if needed
- • No oral/IV benzodiazepine sedation in practice for severe or untreated OSA unless capnography, airway equipment and trained staff are available
- • Ask the patient to bring their CPAP/mandibular advancement device for any sedation; semi-upright position
- • Screen undiagnosed snorers with STOP-Bang; refer for sleep study if high risk
Medications to avoid → safer alternative
- Benzodiazepine sedation — oral or IV midazolam, diazepam, triazolam (unless with capnography & airway support)Local anaesthesia with behavioural anxiety management; nitrous oxide inhalation sedation
Upper-airway collapse and respiratory depression in OSA.
- Opioid analgesics — codeine, tramadol, dihydrocodeineParacetamol ± ibuprofen (if no NSAID contraindication)
Opioid-induced respiratory depression is increased in OSA.
