Awake Fiberoptic Intubation in Patients with a Difficult Airway: Comparison of Ivory North Pole and PVC Portex Tubes

Susmitha B | Sneha Telange | Rajendra D Patel

Abstract: Awake fibreoptic intubation (AFOI) is one of the recent advances in the field of airway management. Various types of endotracheal tubes have been used for the fibreoptic technique. We have compared ivory North Pole (NP) and portexpvc tubes with regard to ease of intubation in terms of intubation time, number of attempts, haemodynamic parameters and incidence of complications, in 34 patients of anticipated difficult intubation posted for elective surgeries. Incidence of successful intubation in first attempt was 47% with NP and 29% with PVC tube. Mean duration of intubation was 7.12min and 7.53min in NP and PVC group respectively. Complications like bleeding and secretions were significantly more in PVC group. We conclude that the ivory North Pole tube is better than the PVC portex tube, probably due to its texture and increased flexibility.
