Alternative toothless mask position
An alternative position for holding the facemask when bag-mask ventilating edentulous patients is described and evaluated. 49 patients with inadequate seal and air leak during two-hand positive-pressure ventilation had significantly improved ventilation as measured by reduced air leak and increased … Continue reading
Taming the Ketamine Tiger
A paper of great interest for those of us who spend a lot of time teaching the use of ketamine describes its history from initial synthesis in the early 1960s. Ketamine pioneer Edward F. Domino, M.D describes how it was … Continue reading
Unexpected survivors after pre-hospital intubation
Data on patients with moderate to severe traumatic brain injury from the San Diego Trauma Registry were analysed using modified TRISS methodology to determine predicted survival, from which an observed-predicted survival differential (OPSD) was calculated. The mean OPSD was calculated … Continue reading
Weight formula for kids
The traditional ‘APLS formula’ for weight estimation in children based on age (wt in kg = [age+4] x 2) is recognised as underestimating weight in ‘developed’ countries, with the degree of underestimation increasing with increasing age. Several authors have attempted … Continue reading
ETCO2 and ROSC
One for the ‘hardly surprising’ category…. A study of end-tidal CO2 during out-of-hospital adult and child cardiac arrest resuscitation showed a sudden rise in CO2 was associated with return of spontaneous circulation (ROSC), suggesting that witnessing this would be a … Continue reading
Etomidate in RSI – systematic review
A systematic review of 20 included studies comparing a bolus dose of etomidate for rapid sequence induction with other induction agents resulted in the following conclusion: “The available evidence suggests that etomidate suppresses adrenal function transiently without demonstrating a significant … Continue reading
Tracheal tube cuff pressure in flight
Tracheal tube cuff pressures increased from a mean 28.7 cm H2O pre-flight to 62.6 cm H2O in flight (mean altitude increase 2260 feet) in a Swiss helicopter-based study. At cruising altitude, 98% of patients had intracuff pressure >30 cm H2O, 72% had … Continue reading
Tactical Combat Casualty Care
The brave men and women of the military not only risk their lives for us – they also provide a wealth of trauma experience and publish interesting stuff. This month’s Journal of Trauma contains a military trauma supplement. One of … Continue reading
Less RSI desaturation with Roc
Some of my pre-hospital critical care colleagues in the UK exclusively use rocuronium in preference to suxamethonium for rapid sequence induction (RSI) of anaesthesia in critically ill patients. I couldn’t see a good reason to switch although now there’s some … Continue reading
Pre-hospital RSI successes
A couple of papers in Prehospital Emergency Care this month contribute to the pre-hospital airway management / rapid sequence intubation (RSI) literature. Intensive physician oversight of a pre-hospital RSI program increased the prescription of post-intubation morphine and midazolam, and decreased … Continue reading
