AbstractAim: Airway management in patients with thyroid swelling undergoing thyroid surgery.
Methodology: After approval from Institutional ethics committee, we conducted a prospective observational study including 60 consenting patients with thyroid swelling undergoing thyroidectomy. A standard OT protocol for routine pre anaesthetic check up was followed. The usual airway parameters such as mouth opening, MPC, slux, thyromental distance (TMD), neck movement were assessed. The euthyroid status of the patient was confirmed.
Results: In 54 (88.3%) patients propofol was used as induction agent. In 3 (5%) patients combination of dexmedetomidine & propofol was used as induction agent. In 2 (3.3%) patients sevoflurane and propofol was used as induction agent. In 1 (1.4%) patient etomidate was used as induction agent. 16 (26.7%) of patients required external laryngeal manoeuvre whereas 44 (73.3%) didn’t require external laryngeal manoeuvre. Highest percentage of patients 48.3% (29) were intubated in 15-30sec, 13 (21.6%). patients required 30-45 sec, 12 (20%) required less than 15 sec, while 6 (10%) patients required more than 45 sec. Maximum time required for intubation was 58 sec. 1 (1.7%) patient had complaint of hoarseness of voice post-operatively. 1 (1.7%) patient had tracheomalacia for which tracheostomy was done. 1 (1.7%) patient was not extubated due to prolonged surgery. no patient had post-extubation desaturation.
Conclusion: From this study we concluded that thyroid swelling accompanied with airway deformity is a risk factor for difficult intubation. A thorough preoperative history in all patients with thyroid swelling is mandatory and should include duration of thyroid swelling, pressure symptoms and radiological investigations of the neck and thorax.
