TEE Async. Flashcards
What kind of procedure is TEE?
Invasive
What does TEE require in terms of skill?
Expertise, Non-invasive cardiologists are trained in this
What does TEE need from the patient?
- Cooperation
- Preparation
Where is the Ultrasound traducer on the TEE?
Gastroscope
Images are from where in the chest cavity?
Behind/ under the heart
What are some advantages of TEE?
- Proximity to heart
- No lung and ribs
- Somewhat non-invasive compared to OHS
- Somewhat portable
- Improves imaging for technically difficult patients
- Visualization of posterior structures
What are some disadvantages of TEE?
- Somewhat invasive
- Expertise required
- Patient discomfort
- Complications
- Operator dependent
What is TEE patient preparation?
- Procedure explained
- Patient history taken
- Ensure fasting (patient may vomit during gag reflux)
- Physical
What is the physical portion of TEE patient prep?
- IV started - easier administrations of medications
- Removal of dentures
- Set up ECG
- Set up blood pressure and pulse oximeters
What should be done for patient care during TEE?
- Vitals (O2 and BP)
- Instruction to patient (breathing and swallowing)
- Post examination process
What is included in the patient post examination care?
- Looking for esophageal damage
- Tooth damage
- Blood pressure dropping
What are some indications for TEE?
- Source of embolus
- Valvular disease
- Abnormal LV
- Masses
- Prosthetic devices
- Interoperative
- Aortic disease
- Non-diagnostic TTE
- CHD
What are 4 absolute contraindications for TEE?
- Esophageal strictures, masses, perforations
- Recent bleed or surgery
- Poorly cooperative patient
- Severe respiratory depression
What are some relative contraindications (with caution)?
- Coagulopathy issues
- Restricted cervical mobility
- Recent esophageal trauma/ radiation
- Esophageal varices
- Dysphagia (trouble swallowing)
- Sleep apnea
What are some TEE complications?
- Dental trauma
- Esophageal truama/ bleeding/ perforation
- Laryngospasm or bronchospasm
- **Aspiration
- Dislodgement of endotracheal/ nasogastric tubes
- Sore throat, hoarseness
What are some complications of TEE with the technologist?
- Combative patient under sedation
- Bites
- cleaning
- Vomit
- Equipment damage
What are 5 TEE probe manipulations?
- Advance/ withdraw
- Flexion
- Extension
- Rotation
- Side to side
What are three TEE probe positions?
- Transgastric
- Mid esophageal
- Upper esophageal
Label
What is the most superior TEE view?
Upper esophageal
What are some structures seen with UE view?
- Aorta
- Ao valve
- Superior IAS
- LA appendage
Where is most of the TEE exam done?
Mid esophageal because it is similar to AP4 in TTE
What is seen with ME TEE?
- The MV/TV valves
- IAS
- IVS
- LA appendage
- Almost all structures except LV apex
What is seen with transgastric view?
- Apical structures up to the AV valves
- Especially LV apex
- Apical IVS
