TEE Probe — Insertion Technique + Complications
TEXTEquipment & Safety · 6 min read
TEE is the eye into the heart for cardiac surgery + unexplained periop instability. The probe is also a 30-mm dilator that can perforate the esophagus.
After this lesson you can
2 min read5 sections- Decide whether TEE is appropriate for the patient.
- Insert the probe without injury.
- Recognize esophageal perforation early.
- Avoid pressure injury during long cases.
Indications + contraindications
- cardiac surgery (valve repair, CABG, transplant, congenital)
- unexplained periop instability (RV failure, ischemia, embolism, hypovolemia vs vasoplegia differential)
- VAE detection in sitting cases
- monitoring during high-risk non-cardiac surgery
- esophageal stricture
- recent esophageal surgery
- active esophageal varices with recent bleeding
- perforation
- hiatal hernia (large)
- Barrett's
- recent UGI bleed
- severe coagulopathy
- cervical spine instability (positioning concerns)
Insertion technique — anesthetized patient
Insert orogastric tube first if available to decompress stomach.
Lubricate the probe generously.
Place head in neutral or slightly flexed position.
Open the laryngoscope-free jaw — or use a laryngoscope to lift the tongue + visualize the upper esophageal sphincter.
Pass the probe along the patient's midline, applying gentle continuous pressure as it crosses the cricopharyngeus (most common point of difficulty + injury).
NEVER force.
If resistance is felt, withdraw + reposition.
The mid-esophageal level is ~30-35 cm from incisors in an average adult.
Complications — major
- forced insertion
- pre-existing pathology
- prolonged probe presence during long cases
- repeated probe manipulation
- subcutaneous emphysema
- pneumomediastinum on chest X-ray
- sepsis
- pleural effusion
- NPO
- broad-spectrum antibiotics
- surgical consult — most require operative repair
- dental injury during insertion
- vocal cord injury
- tracheal tube dislodgment from torquing
Complications — minor + transient
Lip + tooth bruising.
Transient mucosal abrasion.
Pressure necrosis if probe left in same position too long — REMOVE probe between TEE views in long cases, don't park it; or rotate position.
Hypopharyngeal pressure can cause cranial nerve palsy (recurrent laryngeal nerve, hypoglossal) — rare but documented.
Cardiovascular: brief HR/BP changes from manipulation are normal; significant arrhythmias rare.
Special-population caveats
Care with esophageal compression of the heart — can cause hypotension in small infants.
Geriatric: increased risk of esophageal pathology + brittle bones; consider TTE as alternative when adequate windows.
Post-radiation neck: fibrosis can make insertion impossible — abort early, don't force.
⚠ Common pitfalls
- Forcing the probe past resistance — esophageal perforation risk.
- Leaving the probe parked in one position for hours — pressure necrosis.
- TEE in active variceal bleeding or recent esophageal surgery — absolute contraindication.
- Missing subcutaneous emphysema post-case — first sign of perforation.
💎 Clinical pearls
- Decompress the stomach with an OG tube before probe insertion.
- Mid-esophageal level ~30-35 cm from incisors in an average adult.
- Withdraw the probe between TEE views in long cases — don't park.
- ME 4-chamber + TG short-axis are the two highest-yield views for periop hemodynamics.
