Not just a Patient that Snores. Obstructive Sleep Apnoea: The Perioperative Concerns through the Eye of the Anaesthetist

Obstructive sleep apnoea (OSA) has life threatening perioperative cardiorespiratory implications. As patients present to hospital for incidental surgery unaware of their condition, perioperative practitioners need a thorough knowledge of OSA to allow optimisation before theatre. Elective cases should be delayed for investigation and treatment if OSA is suspected. In theatre cardiorespiratory problems should be managed by a senior anaesthetist and a perioperative team alert to the risk of post-operative hypoxia.
