A Comparative Study of diagnostic fibreoptic bronchoscopy under airway blocks and bronchoscopy under sedation

Dr Mohammed N Ali, Dr Pradeep Pendyala

Abstract :

Introduction Bronchoscopy allows to examine and visualize the inside of a person‘s airway and lungs for any abnormality such as foreign bodies, bleeding tumours, or inflammation. Present study was underatken to study if diagnostic fieoptic onchoscopy can be done under airway blocks and to compare the results with airway blocks for conducting diagnostic fieoptic onchoscopy under sedation and to find out the ideal way of doing diagnostic fieoptic onchoscopy

Material and Methods: This study was undertaken at Yashoda Super speciality Hospital, Malakpet, Hyderabad in the year 2013–2015 after obtaining the scientific and ethical committee approval. A total of 100 subjects coming for diagnostic fieoptic onchoscopy were randomly allocated into two groups of 50 member each.

Group No. 1: Received sedation for onchoscopy with Inj. Zofer 4mg + Inj. Fentanyl 2mcg per Kg + Inj. Propofol 1mg per kg bolus and then intermittent doses of 0.25 to 0.5 mg per kg.

Group No. 2: Received Inj. Zofer 4mg + Airway Blocks of Superior Laryngeal and Recurrent Laryngeal Nerves with 1% and 4% lignocaine respectively.

Results :

The groups were examined for ease of procedure, haemodynamic stability and incidence of side effects.

Conclusion :

Airway Blocks of Superior Laryngeal and Recurrent Laryngeal Nerves with 1% and 4% lignocaine respectively was found to be much superior and much safer with minimal haemodynamic instability and negligible side effects compared to onchoscopy with Inj. Zofer 4mg + Inj. Fentanyl 2mcg per Kg + Inj. Propofol 1mg per kg bolus and then intermittent doses of 0.25 to 0.5 mg per kg.
