b) The doses of these medications where given at the discretion of the proceduralist up to a maximum of 100ug and 5mg respectively.
c) Medications were administered intravenously.

Outcomes
Primary outcome [1] 296869 0
Comfort score by visual analogue scale.
Timepoint [1] 296869 0
Day following procedure via telephone interview.
Primary outcome [2] 326671 0
Willingness to repeat procedure if required.
Timepoint [2] 326671 0
Day following procedure via telephone interview.
Secondary outcome [1] 319559 0
Staff resource use - this will be assessed by the procedural log. The number and period of time staff are required during the procedure and during pre and post procedural periods will be measured.
Timepoint [1] 319559 0
Staff will log time and staff numbers throughout the procedure.
Secondary outcome [2] 319560 0
Staff comfort score by visual analogue scale
Timepoint [2] 319560 0
Measured at the completion of the procedure, however, representing an overall score for the procedure.
Secondary outcome [3] 319561 0
Level of sedation as defined by BIS monitoring
Timepoint [3] 319561 0
This is a second to second score which is reported in the anaesthetic log. At the completion of the procedure we will have a BIS score vs time plot for the entirety of the procedure.
Secondary outcome [4] 319813 0
Complications during procedure or recovery period. Complications included hypotension, bronchospasm, haemoptysis (small and large volume) and cardiovascular event. These were assessed either visually with haemoptysis, or with bedside cardiorespiratory monitoring equipment, as is standard during the procedure and during the post procedure recovery phase.
Timepoint [4] 319813 0
Complication events were recorded during the procedure log and assessed following the procedure in the anaesthetic recovery room.

Type of endpoint/s
Safety/efficacy
Statistical methods / analysis
Comparisons will be performed with the Student t test, chi-square or Fisher exact test, as appropriate,
Sample size has been determined with power calculation using a significance level 5% (alpha = 0.05) and powered to 90% (beta = 0.1). The non-inferiority limit, d, of 15% was used. This is on the basis that a previous similar study (Clark G, Licker M, Younossian AB, et al. Eur Respir J 2009; 34: 1277–1283) that was able to show significance with a non inferiority limit of 35%.
Our primary end point data will look at a continuous variable (sample size =22) as well as a binary dichotomous variable (sample size = 98).
