How does the addition of Ketamine to propofol for sedation for Transoesophageal Echocardiography followed by cardioversion influence haemodynamics, anaesthesia and patient satisfaction? A randomised controlled trial versus propofol

Do patients undergoing transoesophageal echocardiography followed by cardioversion randomised to a combination of ketamine and propofol, versus propofol alone, have less impairment of left ventricular function?

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.

Interventions

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 pr

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.
