Difficult tracheal intubation: a retrospective study

Area of Science:

• Anesthesiology
• Critical Care Medicine
• Otolaryngology

Background:

• Failed endotracheal intubation presents a significant risk, potentially leading to fatal outcomes.
• Oropharyngeal anatomy is implicated in the difficulty of tracheal intubation.
• Previous studies focused on obstetric patients, necessitating broader investigation.

Purpose of the Study:

• To investigate the correlation between oropharyngeal anatomy and difficult tracheal intubation.
• To extend the analysis of failed intubation cases to nonobstetric surgical patients.
• To identify predictors for challenging endotracheal intubation procedures.

Main Methods:

• Retrospective analysis of patients with a history of failed endotracheal intubation.
• Inclusion of both obstetric and nonobstetric surgical patient cohorts.
• Examination of oropharyngeal anatomical features in relation to intubation success.

Main Results:

• A correlation was observed between oropharyngeal anatomy and the degree of intubation difficulty.
• The incidence of failed intubation in obstetric patients was 7/1980 over 3 years.
• In surgical patients, the incidence of failed intubation was 6/13,380.

Conclusions:

• Oropharyngeal anatomy is a significant factor in predicting difficult tracheal intubation.
• Expanding the study to surgical patients provides a larger dataset for analysis.
• Screening tests for predicting intubation difficulty are essential for improving patient safety.
