Prehospital emergency anesthesia with intubation saves lives of trauma patients

A new study suggests that trauma patients have a significantly higher chance of survival if a breathing tube is inserted before they reach the hospital, rather than waiting until they are admitted. Researchers at University College London (UCL) and the Severn Major Trauma Network conducted the analysis, which provides the strongest evidence to date supporting prehospital emergency anesthesia with intubation for high-risk trauma patients.

The Power of Early Intervention

The research, published in The Lancet Respiratory Medicine, found that prehospital emergency intubation could improve 30-day survival rates by 10.3%. Extrapolating these findings to the UK, researchers estimate that approximately 170 lives could be saved each year if all trauma patients requiring prehospital intubation received it.

AI and Machine Learning

The study utilized a new machine learning model, called ‘Intub-8’, which predicted patient outcomes based on eight routinely collected prehospital measurements. This AI-assisted modelling allowed researchers to isolate the impact of intubation from other factors, such as the severity of the injury. Researchers analysed data from 6,467 trauma patients treated at Southmead Hospital Major Trauma Centre in Bristol.

Dr. Amy Nelson, joint first author from UCL Queen Square Institute of Neurology and King’s College London, explained that determining the best timing for intubation has been challenging due to ethical constraints preventing randomized trials. “Emergency care decisions made before hospital admission depend on the combination of many measurements taken under pressure,” she said. “We used these measurements to answer the question…which showed us that prehospital intubation saves lives.”

Cost-Effectiveness and Future Implications

Beyond the potential to save lives, the study also highlighted the cost-effectiveness of prehospital intubation. Researchers estimate annual cost savings of around £101 million for the UK, stemming from reduced costs associated with further care and the lives saved.

Professor Parashkev Nachev, joint senior author from UCL Queen Square Institute of Neurology, emphasized the importance of using causal inference and artificial intelligence when randomized controlled trials are not feasible. Associate Professor Julian Thompson, joint senior author and Clinical Director of the Severn Major Trauma Network, noted the study’s potential to reshape how healthcare services care for severely injured patients.

Frequently Asked Questions

What did the study find regarding survival rates?

The study found that prehospital emergency intubation of high-risk trauma patients could improve 30-day survival by 10.3%.

Who currently provides prehospital intubation in the UK?

In the UK, prehospital intubation is currently provided only by air ambulance services.

How was the impact of intubation isolated from other factors?

Researchers used AI-assisted modelling and a new machine learning model, called ‘Intub-8’, to predict both who would need intubation and who would likely survive, isolating the impact of intubation from other factors like injury severity.

Could wider access to prehospital intubation services, potentially through increased funding for air ambulances or training for ground ambulance teams, significantly alter trauma care protocols in the future?
