OXYGEN DESATURATION FOLLOWING SEDATION FOR REGIONAL ANALGESIA
Instituut voor Anesthesiologie, Sint Radboud Ziekenhuis Postbus 9101, 6500 HB Nijmegen, The Netherlands
Moderate to severe arterial oxygen desaturation (SaO2 7588%) occurred in three of four patients who were given sedation during regional conduction block without the administration of oxygen. No desaturation occurred in six patients given oxygen 2 litre min1 via a nasal catheter during similar procedures. It is concluded that patients undergoing regional conduction block with concurrent sedation should receive additional oxygen routinely unless a pulse oximeter is available for monitoring.
