I was lucky enough to team up with Simon Laing from the RCEM FOAMed network to podcast on the top 10. We are jointly publishing this on both sites so please have a listen, follow the references and if you agree or disagree with my opinions please let me know in the comments section, on twitter or on facebook. So with that in mind, in no particular order and with a selection process entirely based on ‘stuff I like’ here’s the top 10.

Number 1. PROPPR trial

We’ve talked about this on the St.Emlyn’s site already. This is an RCT of 1:1:1 vs. 1:1:2 (platelets/FFP/blood). It’s a well conducted trial relevant to our trauma patients who need blood. The bottom line? Use 1:1:1 it’s statistically just as good, and there is a suggestion that this trial is under-powered to demonstrate superiority of 1:1:1. Read more from Salim at REBEL EM and listen to Ken and Salim discuss it at SGEM.

 Number 2. Progesterone in major head injury

Again a paper we’ve reviewed here at St.Emlyn’s. A well designed RCT that promised much on the management of patients with GCS 4-12 significant head injury. The bottom line? No benefit to progesterone infusions in these patients. So it’s a no to progesterone in the real world despite promising animal data.

Number 3. Fixed dilated pupils in head injury – What’s the prognosis?

Arguably better than you thought! A small systematic review that gives us the real world outcome data for head injured patients with fixed dilated pupils. The headline here is that those with an extradural and fixed dilated pupils have a >50% chance of a good neurological recovery. Please, please, please aggressively manage these patients and avoid any nihilism as a result of this pupilary sign. Don’t forget to sign up to one of the authors, Mark Wilson’s,GoodSAMApp too.

Number 4. How good is REBOA?

There’s lots of interest in REBOA at the moment and I get that. It’s exciting and pathophysiologically it makes sense for patients with exsanguinating lower body bleeding. It’s fairly new to the UK and centres such as London HEMS are instituting it carefully and systematically with good training and audit processes. What of the rest of the world though? Well others, such as the Japanese, have been doing this for some time and in a registry based paper they compared patients receiving REBOA with matched controls who did not. They found a much higher mortality (75%)in those receiving REBOA. There are many reasons why this may be and it’s not reason to NOBOA (get it ?!?)but it does mean we need to carefully evaluate how we impliment it, who gets it and what happens to them. If 99% were going to die anyway but by using REBOA the Japanese managed to improve it to 75% that’s a positive result. We just don’t know yet, but we may do soon as the AORTA trial is ongoing in the US. More on REBOA at LITFL,  EMCRIT and RCEMFOAMed.

Number 5. The HIRT trial. An RCT of Physician PHEM for head injured patients.

This trial is worth a read as it’s big, expensive, ambitious and controversial. An RCT of physician staffed helicopter vs. ground paramedics for the treatment of head injured patients in Sydney. The trial reports an improved outcome for GCS<10 patients, no difference for GCS <14. However, lots of controversy and worth reading comments on this from luminaries such as Karel Habig in Sydney, with some real concerns about intention to treat vs. delivered therapies and interventions. You should also read the authors own reflections on prehospital research here. Whatever you make of this study if you are interested in prehospital trauma research it’s well worth reading the paper and all the controversies that surround it.

Number 6. DSI for the hypoxic patient

A bit of a cheeky one this as an observational study on the use of Delayed Sequence Intubation. Sadly only 2 trauma patients in the study so arguably should not be here. However, as a proof of concept for combative, hypoxic patients it may be helpful. More on DSI here. Arguably we’ve been doing it for years but previously never had a name for it…….

Number 7. Gestalt in predicting major bleeding in trauma patients.

When I’m in the resus room as a trauma team leader I often wonder whether or not to activate the major haemorrhage protocol. Sure, for those patients who are hosing blood out of every orifice (new and traditional) then sure it’s easy. Similarly for those patient who are completely fine with no apparent on going bleeding it’s easy (don’t do it). However, there are a number of patients that I see where it’s a tough call. I’ve often thought that I’m just not very good at this, I’ve flirted with objective scores and worried that others are better than I. The bottom line is that despite many years of trauma management I still struggle, so I was interested to see this paper on clinician ‘Gestalt’ in the resus room with reference to whether patients need MHPs. The bottom line is that clinicians are poor at deciding which patients are going to require major haemorrhage and so are the objective scores. Gestalt may not be that great. As a Trauma Team Leader this tells me that I must be vigilant and constantly reassess the need for 1:1:1 resuscitation.

Number 8. Standardising drugs for trauma RSI.

I chose this paper as it’s an issue in Virchester. We do a lot of RSI in our resus and it’s noticeable that there is much variation in drug use. In contrast those I really respect as resuscitationists in PHEM have adopted standardised approaches to drug use. KSS looked this and compared an old regime (etomidate plus sux) vs Ket/Fent/Roc and found the latter to give better views and cardiac stability. Although a before/after historical trial it fits with my belief that that Fent/Ket/Roc is a good regime to use as a baseline protocol for trauma (ED) RSI.

Number 9. TXA in severely injured patients.

If you follow St.Emlyn’s you will know that we are big fans of TXA. However, the world (mostly US/Aus) don’t always agree. CRASH-2 was a multicentre, multinational study that involved different types of trauma systems. Some in what they perceive to be ‘advanced’ trauma systems claim that TXA would not work for them. I recently experienced this in the US where this trial (observational crap) was used to refute CRASH-2. Honestly? I don’t get it, but the bottom line is that patients may be losing out across the world as a result of the lac of adoption of TXA.

Number 10. Lastly Thoracotomy in blunt trauma.

I have been taught for many years that there is no role for thoracotomy in blunt trauma. I can remember waiting to receive a patient with pre-alerted traumatic cardiac arrest in Virchester, I’d briefed the team and we were prepped when just before the patient arrived the consultant surgeon burst through the door and immediately shouted to all present ‘The one thing we are not ******** doing is a thoracotomy’. It was an interesting moment…….., and some education took place….. Anyway, it reflects the dogma that there is no role for thoracotomy in blunt trauma, but is that right? Well perhaps not. In this systematic review there are some survivors, albeit just 1.5% neurologically intact. Is that a futile therapy? Perhaps not and if your patient has a potentially survivable injury and arrests in front of you it may be worth a go. The authors outline an algorithm for patient selection. Read more at EMLitofNote.

So there you go. Ten papers in a fairly lean year for high quality science, but much to think about and a few that may really change practice in the resus room. As with everything on St.Emlyn’s don’t take my word for it. Follow the links, listen to the podcast, read the papers and make up your own mind :-) .

Hands-On Defibrillation: If the Glove Fits…You Must Acquit!

Hands-On DefibrillationWe’ve had some heated debates on the topic of hands-on defibrillation (HOD) for the past few years. We all know the most important time to avoid a pause during CPR is the perishock pause ([1]). We also know that despite lots of safety data ([2][3]) and safe experience doing HOD ([4], Johnson) there are still concerns over the potential electrical leak using common exam gloves ([5], [6][7], [8][9]). For those who don’t enjoy a little electrical spice in your resuscitations, some recent articles have shown ways in which the safety of HOD can be mitigated using inexpensive tools.

Protective Equipment Makes Hands-On Defibrillation Safe


Resus BlanketYu and colleagues [10]
 used a resuscitation blanket in an animal model of 15 pigs to demonstrate the protection from electrical current during the HOD time. The resuscitation blanket is made from light weight insulating materials which have stable physical characteristics, such as high dielectric strength and outstanding resistance to flame. Even at levels of 360J (well beyond what most use) it was deemed to protect providers against dangerous levels of electricity.

Class 1 electrical insulating glovesJust recently, Deakin and colleagues [11] did a study, taking patients requiring elective cardioversion and performed 82 hands on cardioversions wearing Class I electrical gloves similar to that worn by professional electricians. They used a scale to ensure 20kg of pressure on the chest and had the pads placed in an anterior posterior placement. They placed electrodes on the chest near the pads and then attached them to the provider with a resistor to measure the possible scenario of a patient/provider contact during cardioversion. The peak levels of energy transfer fell well below the industry safety standard of 1 milliamp.   The conclusion of the author and this reviewer is that there should be no reason we should need to pause compressions for defibrillation when wearing the proper protective equipment. Go get your gloves on!

Clinical Bottom Line: The resuscitation blanket or Class I electrical gloves are potentially safe and useful tools which protect the rescuer from hands-on defibrillation shocks, allowing for uninterrupted chest compressions, and therefore improving defibrillation success.

Always look at the bright side of life, by Meritxell Tapia

My alarm-clock sounds and I weak up plenty of satisfaction, happiness, and full of life. This is priceless.

The day of Saint Jordi there was an inflection point in the ICU of the Broggi Hospital.

But to reach it, sometimes we have to go through situations in life that make us think and rethink many aspects of both personal and professional life.

In my case, my turning point was on 11 April, 2014. As many people who have suffered a traffic accident usually say, that day I was born again. Life took me to be admitted during a week in the ICU and that personal experience made me rethink many aspects in my professional life as a nurse in intensive care.

At that time I meet the IC-HU Project. In my long times of recovery, I started to read about this great project and something inside has changed.

This year we organize at Hospital Sant Joan Despí Moisès Broggi the annual Conference of Catalan society of Intensive Care and Critical Medicine (SOCMIC), and we thought that we had to share the project and ideas for awakening that change we all need.

We did it. And that small revolution motivated us in such a way that the first result was the concert that we organise within the ICU, in occasion of the Diada de Saint Jordi.




I had the pleasure of seeing in the ICU of the Broggi, how my coworkers, family, and patients are touched, they sang, danced and clapped with the music of "The Broggi´s Band" concert. We deliver roses for each patient and their families.





Sincerely, the best gift of Sant Jordi, there were not a rose or a book, they were those tears in the eyes of all those who were there. Patients, families, physicians, nurses, aides, and the rest of the Hospital staff.





I would like to congratulate all my coworkers for believing in this project and make it reality and all the members of "The Broggi´s Band", without you this wouldn't be possible...



Let the music keep sounding!


Airway Courses Galore!

Everyone who looks after critically ill patients needs to be able to manage airway crises. We all want to be better at it. We all can get better at it. Fortunately, there are plenty of courses around to help us become ‘expert enough‘. Fortunately, you can’t do too many airway courses 😉

Here are the courses I’m teaching on this year:

  • I’ve designed a simulation-based course called the Critically Ill Airway course run by The Alfred ICU and Monash University. It focusses on cross-specialty team-based management of airway crises in the critically ill, beyond the operating theatre. It fulfils CICM requirements for difficult airway management training requirements and  is strictly for those with prior airway experience. The next course in May is sold out, however dates have just been released for the next one: December 8th and 9th 2015. Get in quick, as this is likely to rapidly sell out again.
  • If you can’t wait that long, I’m also teaching on Adriano Cocciante’s ACE course on Saturday July 18th 2015. I had a great time on this course last year – it is ideally suited to emergency medicine trainees. Joe Rotella wrote a review on LITFL from a trainee’s persective here: Are your airway skills ACE? Learn more about the ACE course, and how to register, at the ACE website.
  • Just before SMACC Chicago, I’ll be teaching on Rich Levitan’s Yellowstone Airway course. This sold out long ago, but you should keep an eye out for future events.
  • Finally, if you’re planning to head to EuSEM in Torino, Italy in October 2015, anticipate a satellite workshop involving Rich Levitan, Reuben Strayer and myself (among others)…

Hope to see you on the handle end of a laryngoscope soon!

Dog Bite/ Rabies: Things what you need to know

This week, I have a podcast for you. 

We are going to talk about Dog Bite/Rabies. The reason I chose this topic is because this is something which is still fairly common in India (Dog Bite) and the incidence of rabies in India has now been constant for about a decade. One of the reasons for this is poor knowledge of post exposure prophylaxis among medical professionals. I take you through the national guidelines for treating dog bites (Indian Guidelines).  I hope this will help to change the scenario:

Listen to the podcast.

Thanks!
