Anaesthetic considerations for tracheal resection in oncological thyroid surgeries

Abstract

Patients were monitored with electrocardiogram, SpO 2 , end-tidal carbon dioxide monitoring, non-invasive blood pressure, temperature, neuromuscular monitoring and urine output. Seven patients in planned tracheal resection group underwent additional specific investigations namely contrast-enhanced computed tomography (CT) scan of neck and thorax, bronchoscopic evaluation and pulmonary function test (PFT). [3],[4] Pre-operative evaluation should be comprehensive; history and progression of exertional dyspnoea suggest narrowing of tracheal diameter to 50% or 8 mm. Inspiratory stridor at rest indicates a further reduction of tracheal diameter to 5-6 mm. [5] A few specific investigations contribute significantly to pre-operative assessment in patients for tracheal resection.
