Aim: The aim of the present study was to compare oxiport laryngoscope blade and miller laryngoscope blade for neonatal and infant intubations. Material & Methods: This controlled interventional study conducted in the Department of Anaesthesiology for one year in which 100 neonates/infants in groups of 50 each posted for surgery in paediatric operation theatre over a period of 6 months were included in the study. Results: A total of 100 patientswere included in the study, with 50 patients in the Miller group and 50 patients in the Oxiport group. Both groups were similar in terms of age, sex, weight, average time to intubation, and the anaesthesiologist doing the laryngoscopy. In the Miller group, the occurrence of mild desaturation (SpO2 levels up to 90%) was 84%, whereas in the Oxiport group it was 92%. In the Miller group, the occurrence of moderate desaturation, defined as SpO2 levels between 85% and 89%, was 4%. In contrast, the Oxiport group had a higher incidence of 8%. The Miller group had an incidence of severe desaturation (SpO2 <85%) of 12%, whereas the Oxiport group had an incidence of 0%. Conclusion: Apneic laryngeal oxygen insufflation with the Oxiport laryngoscope blade reduces the occurrence and speed of oxygen desaturation, while providing improved hemodynamic stability, in comparison to the Miller blade, during intubation of neonates and infants.
