Junior pre-hospital doctors spend a bit longer on scene

More junior pre-hospital doctors took longer on scene than their senior colleagues according to a German study, although patient clinical factors were the main determinant of scene time. The majority of cases were non-trauma presentations

Pre-hospital intubation experience and outcomes

Hospitals and medical personnel performing high volumes of procedures demonstrate better patient outcomes and fewer adverse events. The relationship between rescuer experience and patient survival for out-of-hospital endotracheal intubation is unknown.

An American study analysing 3 statewide databases with 26,000 records aimed to determine the association between endotracheal intubation experience and patient survival.

In-the-field intubators were EMS paramedics, nurses, and physicians, although paramedics performed more than 94% of out-of-hospital tracheal intubations. Although all air medical rescuers may use neuromuscular- blockade-assisted (rapid sequence) tracheal intubation, select ground EMS units are allowed to use tracheal intubation facilitated by sedatives only; the rest are done ‘cold’.

Patients in cardiac arrest and medical nonarrest experienced increased odds of survival when intubated by rescuers with high procedural experience. In trauma patients, survival was not associated with rescuer experience.

The odds of survival for air medical trauma patients were almost twice that of other patients, which may be related to the use of neuromuscular- blocking agents by air medical crews, or due to more specialised critical care training. The authors suggest that rescuers should perform at least 4 to 12 annual tracheal intubations.

Win with the chin

Medical students and junior doctors were successfully taught correct airway management positioning for intubation on a manikin when told to position the manikin in the best position to win a running race, where the chin wins the race. (The so-called ‘win with the chin’ position). This was superior to the traditional ‘sniff the morning air’ position.

Ad hoc resus teams less effective

During simulated cardiac arrest resuscitations, a comparision was made between those run by teams that had had time to form before the arrest, and those that had to be assembled ad hoc after the arrest occurred. 99 teams of three doctors, including GPs and hospital physicians were studied. ACLS algorithms were less closely followed in the ad hoc formed teams, with more delays to therapies such as defibrillation. Analysis of voice recordings revealed the ad hoc teams to make fewer leadership utterances (eg. ‘we should defibrillate’ or ‘the next countershock will be 360J’) and more reflective utterances (eg. ‘what should we do next?’). The authors suggest that team building is therefore to be regarded as an additional task imposed on teams formed ad hoc during CPR that may substantially impact on outcome. No surprise to those of us who banned ‘cardiac arrest teams’ from our emergency department resuscitation rooms many years ago!
