Anesthesia is maintained with propofol by infusion (5-10 mg/kg/hr). The TEE probe is passed as the patient loses consciousness and is protected by a bite block next to which O 2 (8 l/min) flows. Jaw thrust is used to maintain the airway as needed. Any patient movement is treated with further propofol (0.25mg/kg).
The Test. The TEE is done by a cardiology doctor who specializes in the care of patients with heart problems. It is done under sedation because your child needs to be very calm for it. Although not fully asleep, your child will not feel any pain during the test or remember it afterwards.
Doctors may recommend transesophageal echocardiography (TEE) to help diagnose a heart or blood vessel disease or condition. TEE can be used for adults and children. Doctors also may use TEE to guide cardiac catheterization, help prepare for surgery, or assess a patient’s status during or after surgery.
Your doctor may suggest an echocardiogram to: Check for problems with the valves or chambers of your heart. Check if heart problems are the cause of symptoms such as shortness of breath or chest pain. Detect congenital heart defects before birth (fetal echocardiogram)Mar 30, 2021
Current guidelines recommend that patients receive anticoagulants for 3-4 weeks before and 4 weeks after cardioversion. With the development of transesophageal echocardiography (TEE), the risk of thromboembolism and alternative anticoagulation strategies have been evaluated in patients with atrial fibrillation.
The procedure usually lasts about 10 to 15 minutes. When they are finished taking pictures, the tube will be removed. there are no clots, the team can move forward with the cardioversion. If the images show you have one or more clots in your heart, you will NOT have cardioversion until the clots are treated.
What to Expect After Your TEE. After your test, you’ll rest in a recovery area. Staff will watch your heart rate, blood pressure, and oxygen levels. Once those vital signs are stable, you can swallow normally, and you feel alert, your nurses will take off your chest electrodes, cuff, and clips, and remove your IV…
In the non-invasive cardiac diagnostic settings worldwide, a transesophageal echocardiography (TEE) can be performed with or without conscious sedation. According to the guidelines for performing a TEE, the procedure is well tolerated by an unsedated patient who is adequately given oral anaesthesia  .
A TEE is done when your doctor needs a closer look at your heart or does not get the information needed from a regular echo. You may need a combination of a TEE, Doppler ultrasound and color Doppler to get information about how blood flows across your heart’s valves.Jul 16, 2019
Because of the sedative, you may not be entirely awake for the test. Your heart rate, blood pressure and oxygen level of your blood will be closely monitored during and immediately after the exam. The TEE takes approximately 90 minutes for preparation and procedure.
