A thyroidectomy is a procedure used to treat patients with hyperthyroidism that has not responded to conservative medical treatment. Procedure can involve the removal of the entire thyroid gland (total thyroidectomy), removal of 1 lobe (thyroid lobectomy, or hemithyroidectomy), or some variation. The procedure is usually done as an open thyroidectomy, though a minimally invasive transoral thyroidectomy can also be performed.
Preoperative management
Patient evaluation
| System | Considerations |
|---|---|
| Airway | Large goiter can compress airway or cause vocal cord paralysis |
| Neurologic | |
| Cardiovascular | Tachycardia, tachyarrhythmias |
| Pulmonary | |
| Gastrointestinal | |
| Hematologic | |
| Renal | |
| Endocrine | Thyroid storm |
| Other |
Labs and studies
- Thyroid studies
- BMP
Operating room setup
Patient preparation and premedication
N/A
Regional and neuraxial techniques
- Surgeon may be able to infiltrate the site with local
Intraoperative management
Monitoring and access
- Standard ASA monitors
- IONM (intra operative nerve monitoring) for recurrent laryngeal nerve
Induction and airway management
- NIMS endotracheal tube (for neuro monitoring)
- Video laryngoscope for surgeons to ensure proper electrode placement
Positioning
- Supine
- Some rotate the bed 180 degrees
Maintenance and surgical considerations
- Avoid paralysis
- Consider remifentanil instead of paralytic agents, (0.05-0.2mcg/kg/min typically throughout the case)
Emergence
- Avoid bucking/coughing
- Consider deep extubation
- Consider leaving remi on
Postoperative management
Disposition
- PACU, stay in hospital
Pain management
- Pain is worse with minimally invasive transoral approach.
- Usually can be managed with tylenol and oral opioids in PACU, can consider IV opioids as backup
Potential complications
- Neck hematoma is rare but can develop rapidly, resulting airway compromise. Thus it is a surgical emergency requiring prompt takeback.
- Recurrent laryngeal nerve injury, if unilateral, results in a hoarse voice, but if bilateral, can result in obstructed airway requiring emergent tracheostomy
- Hypocalcemia
Procedure variants
