Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Propofol and ketamine for sedation for Tranoesophageal Echocardiography followed by Cardioversion (TOE cardioversion).
1/ propofol 200mg and ketamine 40mg will be combined in the same syringe (propofol 10mg/ml, ketamine 2mg/ml). After 25mcg of fentanyl intravenously (IV) 2-4mL boluses of the drug combination will be administered intravenously (IV) every 15-30 seconds according to clinical response. Treatment in this method will be continued until sucessful cardioversion or abandoning of the procedure as decided by the treating cardiologist.
2/ Cardioversion will be external with pads placed by the cardiologist, usually antero-posterior (AP) positioning is used. A single episode of care (with number of attempts at cardioversion determined by patient response) will be studied.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Recruitment in day of surgery area of patients scheduled to undergo TOE+cardioversion. Randomisation to treatment or control based on recruitment order. (list held in anaesthetic dept.)
Allocation will not be concealed from the treating anaesthetist but from the observing cardiologist and data collector (one of 4 medical students participating in project)
Sealed opaque envelopes indicating allocation will be viewed by the treating anaesthetist only.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
random sequence generator (web-based computerised)
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Summary
Brief summary
I am aiming to minimise the low blood pressure and worsening of heart function caused by anaesthetic drugs during this procedure (TOE Cardioversion) by combining 2 different anaesthetic drugs.
