Alhamdulillah! A Very Special Milestone in My Anaesthesia Journey ❤️

Today was a very special and memorable day for me. I successfully performed my first fibre-optic intubation in a 5-year-old child with bilateral TMJ ankylosis.

A small patient, a challenging airway, and a huge responsibility. With severely restricted mouth opening, securing the airway in a child with bilateral TMJ ankylosis is a demanding task that requires careful planning, patience, precision, and teamwork.

Alhamdulillah, everything went smoothly, and we were able to successfully secure the airway with fibre-optic intubation.

I would like to express my sincere gratitude and special thanks to Prof. Dr. Selim Sarker Sir and Prof. Dr. Anwar Sadat Sir for their invaluable guidance, support, and encouragement. Their experience and mentorship have always been a source of learning and inspiration for me.

A heartfelt thanks to my entire OT team and everyone involved in making this challenging case successful.

🤲 All praise and success belong to Almighty Allah.

Every difficult airway teaches us something new.
Every successful case makes us more humble.
And every safe outcome is ultimately a blessing from Allah. ❤️

Alhamdulillah for this experience and for another step forward in my journey as an anaesthesiologist.

Last night’s case was my 4th in the past year where tube thoracostomy under local anesthesia preceded induction of general anesthesia in a maxillofacial trauma patient with pneumothorax. Every case reinforces the value of careful planning and adapting the anesthetic approach to ensure patient safety.

Lidocaine helps blunt the intubation reflex by acting at multiple levels—mainly through its local anesthetic and systemic effects:

⸻

🫁 1. Suppression of Airway Reflexes (Local Effect)

Lidocaine blocks voltage-gated sodium channels in sensory nerves of the airway (pharynx, larynx, trachea).

👉 This leads to:
• Reduced transmission of afferent impulses via the vagus nerve
• Decreased coughing, gagging, and laryngospasm

⸻

🧠 2. Central Suppression of Reflex Pathways

When given IV, lidocaine has a mild central depressant effect.

👉 It:
• Reduces reflex activity in the brainstem
• Blunts airway responsiveness during laryngoscopy

⸻

❤️ 3. Attenuation of Sympathetic Response

Laryngoscopy and intubation cause a sympathetic surge → tachycardia, hypertension.

Lidocaine helps by:
• Stabilizing myocardial membranes
• Reducing catecholamine response

👉 Result:
• Less rise in HR and BP

⸻

⏱️ Clinical Use
• IV dose: 1–1.5 mg/kg
• Given ~90 seconds before intubation

⸻

🎯 Summary

Lidocaine reduces intubation reflex by:
• Blocking airway sensory nerves
• Dampening central reflexes
• Blunting sympathetic response

👉 Overall: smoother intubation with less coughing, bucking, and hemodynamic stress.
