Abstract
Patients with large thyroid mass may present in stridor requiring emergency tracheostomy. Securing the airway frst with endotracheal tube
before surgical tracheostomy is the preferred modality in these patients which may be challenging, especially in an emergency. We report the
airway management of a 74-year-old female with thyroid malignancy presented with stridor and was unable to lie supine.
Keywords: Stridor; Sitting position; Fibre optic intubation
Introduction
Airway management of the patients who present with huge thyroid
mass with stridor is challenging for anesthesiologist because of a
potential difcult airway [1]. Prolonged compression over the trachea
can lead to the sudden loss of airway under any kind of anaesthesia
[2]. Awake fbre optic nasal intubation has been reported successful
in patients with enlarged thyroids in a difcult airway situation [3].
However, this can be more challenging when the patient is unable to
lie supine. We present a case of successful awake FOB guided nasal
intubation in sitting position who presented in stridor with a large
thyroid mass with retrosternal extension for emergency tracheostomy.
Case Presentation
A 74-year-old, 45 kg female presented in stridor with a large
swelling predominantly on the right side and front of the neck for
the past 30 years. Tere was a progressive increase in the size of
swelling since last 3 months with difculty in breathing. Tere was
no history suggestive of hypothyroidism or hyperthyroidism and
thyroid function tests were within normal limits. She had a history of
change in voice, stridor and difculty in breathing which aggravated
on lying down for last one and half months. On examination, the
swelling was a multilobulated frm nodular mass on the anterior
and right side of the neck measuring 15 cm × 8 cm in size. Mass
was immobile and extending from the lower jaw to the sternal notch
(Figure 1). Te lower limit of the swelling was neither visualized
nor palpable. Tere were engorged veins visible on the chest and
neck. On airway examination mouth opening was more than two
fngers, Mallampati grade 2 with limited neck extension and severely
restricted neck fexion. Te trachea was deviated to the lef side.
Indirect laryngoscopy revealed restricted mobility of lef vocal cord.
USG neck showed a large multilobulated, heterogeneous, hypoechoic
lesion in the thyroid region with a heterogeneous hypoechoic lesion
at level 1b on the right side and level 2 supraclavicular location. CT
scan chest and neck showed grossly enlarged thyroid gland with
retrosternal extension and marked compression of the trachea (Figure
2). FNAC showed anaplastic carcinoma thyroid. Te patient was in
active stridor and because of huge size and long history of the thyroid
mass, we anticipated difculty in mask ventilation, laryngoscopy and
intubation. Terefore, awake fbreoptic intubation was planned. Tere
was an increase in respiratory distress in the supine position, hence
we planned the intubation in sitting position only. Difcult airway
cart was kept ready. Te procedure was explained to the patient and
written informed consent was taken. Te patient was shifed to the
operation theatre and ASA standard monitors were attached, baseline
vitals included HR 120/min and NIBP 160/90 mmHg and ECG
showed sinus tachycardia. Injection glycopyrrolate 0.2 mg IV was
administered to minimize the secretions. Xylometazoline drops were
instilled in both the nostrils for nasal decongestion to facilitate the
smooth passage of FOB without mucosal injury. Te patient's airway
was anaesthetized with 4% lignocaine nebulization and 10% lignocaine
spray. Oxygen was administered via nasopharyngeal airway in the
other nostril at a rate of 2 L/min. Te fbreoptic bronchoscope was
loaded with a 6.5 mm cufed fexo metallic endotracheal tube and the
patient was made to sit on the operation table. Te anaesthesiologist
was standing on the lef side of the patient-facing the FOB monitor.
Te FOB was inserted nasally and advanced towards the laryngeal
inlet. Te patient was asked to inhale deep and the laryngeal opening
was visualized with great difculty due to distortion of the airway and
2 ml 2% lignocaine was sprayed using the spray as u go technique
to block the superior laryngeal nerve. Te FOB was then advanced
and positioned just above the carina and endotracheal tube was
threaded down the bronchoscope under the vision and the FOB was
removed. Te anaesthesia breathing circuit was attached and the tube
placement was confrmed with capnography. Te patient was made to
lie in the supine position and induction of anaesthesia was done with
fentanyl, propofol and atracurium. Afer securing the airway, ETT
was withdrawn slightly under visual guidance just below the level of
vocal cords and tracheostomy tube was placed. Afer confrmation
of the position of tracheostomy tube through capnography, ETT
was withdrawn out completely. Te tracheostomy tube was frmly
