Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will be rendomised pre sinus surgery to receive either a single spray of modified Moffat’s (adrenaline + cocaine) or dilute adrenaline as nasal preparation (active control).

Modified moffats solution contains 100mg cocaine, 1mg adrenaline and normal saline made to a 10ml solution. This is administered 5ml either side into the nose pre-surgry

Adrenaline contains 10 ml 1:10,000 (1mg) sprayed 5ml either side into the nose pre-surgery

Surgery will be carried out as normal
Intervention code [1] 297212 0
Treatment: Drugs
Comparator / control treatment
Active control group will be patients receiving adrenaline containining 10 ml 1:10,000 (1mg) sprayed 5ml either side into the nose pre-surgery
Control group
Active

Outcomes
Primary outcome [1] 301138 0
To determine the amount and duration of systemic cocaine absorption administered by intranasal atomised modified Moffat’s solution during ESS (composite primary outcome)

Blood samples will be taken to assess cocaine plasma levels
Timepoint [1] 301138 0
Blood samples will be taken at: baseline (pre administration of Moffats solution), 10mins, 20mins, 30mins, 60mins, 120mins, 6hrs, 12hrs
Secondary outcome [1] 331815 0
To determine whether this systemically absorbed cocaine has an effect on depth of anaesthesia during ESS by comparing this with patients receiving only a dilute adrenaline spray.

This will be assessed using a a BIS Registered Trademark sensor to determine depth of anaesthesia. BIS Registered Trademark sensors monitor a patient's electroencephalogram (EEG) and using a proprietary algorithm give a number to represent the depth of anaesthesia. The BIS Registered Trademark monitor used for this study will be a bilateral sensor that will provide a spectral array of EEG.
Timepoint [1] 331815 0
The BIS Registered Trademark monitoring will be carried out during induction and entire anaesthetic given for the operation.
