Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Extubation to nasal prong oxygen at 6L/min versus facemask oxygen at 6 L/min. From extubation until discharge from recovery ward (approximately for 1 hour).
Intervention code [1] 286920 0
Treatment: Devices
Comparator / control treatment
Active control being facemask oxygen at 6L/minute (normal practise). From extubation until discharge from recovery ward (approximately 1 hour).
Control group
Active

Outcomes
Primary outcome [1] 289300 0
Comfort/ tolerance rated as a cumulative score by patient/ theatre nurse/ recovery ward nurse. Rated on 100mm Visual Analogue Scale (VAS).
Timepoint [1] 289300 0
Patient will assess comfort/ tolerance at discharge from recovery ward (for their conscious time post anaesthetic). Approximately at 1 hour post extubation.
Theatre nurse will assess comfort/ tolearnce at 1 minute post extubation.
Recovery ward nurse will rate comfort/ tolerance for the duration of time in recovery at the time of dischrge from recovery ward. Approximately 1 hour post extubation.
Secondary outcome [1] 302188 0
Number of attempted or actual removal of oxygen delivery device by the patient.
Timepoint [1] 302188 0
Cummulatively from extubation until discharge from recovery ward. 1 minute post extubation until approximately 1 hour post.
Secondary outcome [2] 302189 0
Time from extubation until discharge criteria from recovery ward met
Timepoint [2] 302189 0
This would be expected to be 30 minutes until 1 hour post extubation.
Secondary outcome [3] 302190 0
Need for intervention:
Anaesthetic circuit and mask
Application of PEEP
Additional oxygen
Timepoint [3] 302190 0
Time is recorded if any of these outcomes occur. These could occur at any time from time of extubation until approximately one hour post extubation. They are most likely to occur in the first 20 minutes post extubation.
Secondary outcome [4] 302191 0
Minimum recorded haemoglobin oxygen saturation as recorded using a digital pulse oximeter.
Timepoint [4] 302191 0
Pulse oximetry will be recorded for the duration of the study. This is expected to be from extubation until approximately 1 hour post.
