Tracheal intubation practices and adverse events in trauma victims on arrival to trauma triage: A single centre prospective observational study

Background and Aims: Trauma is one of the leading causes of global disease burden. Data on airway management in trauma patients from developing countries, particularly India is sparse. Hence, we planned a prospective observational study to assess the airway management practice patterns and associated complications. Methods: The study was conducted in trauma triage of a tertiary care hospital. Data was collected on all tracheal intubations occurring in trauma victims requiring definitive airway control, a detailed proforma including patient details, mode of injury, drugs used, intubation procedure, and complications were filled out for each patient. Results: We observed that the airway in trauma patients was primarily managed by non-anaesthesia speciality residents (426 patients); anaesthesia residents were primarily called for deferred or difficult intubations. The first attempt success rate of intubation by anaesthesia residents was significantly higher than speciality residents (P = 0.0001; 95% CI 9.02-24.66). Non-anaesthesia residents used midazolam in varying doses (3-12 mg) for intubation, whereas, rapid sequence intubation was the most common technique used by anaesthesia residents. Airway injuries were the most frequent complication observed in 32.8% of patients intubated by specialty residents compared to 5.9% of patients intubated by anaesthesia residents. Conclusion: The trauma triage is a high-volume area for frequent tracheal intubations which are manned by non-anaesthesia speciality teams. A number of factors related to the patient, staff, availability of airway equipment and unfavourable surroundings impact airway management and may explain the high incidence of airway complications, such as airway injuries in these trauma victims.
