AbstractBackground: Nasotracheal intubation consists of blind nasal passage and external manipulation of the endotracheal tube through the glottis (‘conventional technique’), a technique associated with a high incidence of nasal trauma, bleeding and tube cuff damage.
Aims: Aim of our technique to compare old blind technique with new tech niques for ease of intubation using bougie and nasal airway with bougie techniques which facilitate ease of intubation and reduce nasopharyngeal trauma, pain and bleeding.
Settings and Design: These techniques including routine post-induction nasotracheal intubation by blindly passing a nasotracheal tube vs. passing a bougie blindly (‘bougie technique’) verses using a nasopharyngeal airway to guide bougie for nasotracheal for tracheal intubation.
Methods and Material: One hundred fifty adult patients were randomly assigned to three groups A, B and C50 each for the blind techquine, bougie technique and combined nasal airway bougie technique.
Statistical analysis used: social science statistical analysis.
Results: Significant intergroup difference was observed with intubation timings with groups A to B&C (p = 0.0027). The groups B and C showed no significant (p =0.1699) and bleeding during intubation. Differences were observed in bleeding 5 min after intubation or postoperative epistaxis in groups. No inter-group differences were observed in complications related to nasal intubation and nasal pain.
Conclusion: Nasal intubation over a bougie or passing bougie through nasal airwayis as successful as the conventional technique; it also significantly decreases both the incidence and severity of nasopharyngeal trauma and complications
