Agitated Saline, Albumin, or Propofol-albumin Mixture for Enhanced Contrast in TEE Examinations

• Status: Completed
• Trial end date: 2017-09-01
• Target enrollment: 0
• Participant gender: All

Summary

This is a prospective, randomized, controlled study to determine if albumin and propofol or albumin only will provide superior qualitative contrast enhancement during TEE bubble studies compared to agitated saline. Each patient will receive three randomized bubble studies (agitated saline, albumin, and albumin and propofol) using 10 ml of agitated contrast agent. The albumin and propofol mixture will consist of 7 mL of 5% albumin plus 3 mL of propofol (10 mg/mL). Each patient will undergo qualitative review of all 3 bubble studies by 10 different anesthesiologists and/or cardiologists credentialed to read echocardiographic studies at the time of the surgical procedure, and also with retrospective review of the echo video (~200 studies). A bicaval view will be obtained to record a 20 beat loop for each bubble study. Hemodynamic variables prior to injection of contrast agent; and 30 seconds, 1 minute and 2 minutes after injection will be monitored and recorded.
