ALiEM brings us a great overview of maternal cardiac arrest. This article also comes with a link to ALiEM Cards on the same material. If you have never browsed the ALiEM Cards before – they are amazing and definitely worth your time. Articles such as this are always appreciated – any lesson on resuscitation that goes beyond the typical AHA ACLS course is worth a mention. Some really great takeaways here include:
- A great list of common causes of maternal cardiac arrest.
- How to anticipate potential magnesium and calcium based pharmacological treatment of arresting maternal patients.
- Recommendations of IO access above the diaphragm!
- Knowing to expect immediate C-section if ROSC is not within only 2 rounds of CPR.
- Intralipid use guidelines for patients with arrest after potential anesthetic toxicity.
A couple of very good FOAM sites have write ups on Morphine use in acute heart failure. Dr James Fletcher guest writes for R.E.B.E.L. EM on this post. The post references this article, a multicenter, observational, propensity matched cohort study, that compares mortality rates among two groups of acute heart failure patients – those that received Morphine and those that did not. There are some issues with the study, all of which are thoroughly discussed within the article written by Dr. Fletcher. There are also a few other studies mentioned that link Morphine with increased mortality in patients who present with acute heart failure.
One of the best takeaways from this review is this small segment: “The European Society of Cardiology guidelines on the treatment of heart failure recommend against the routine use of opiates, while the American Heart Association recommends opiate use in heart failure be limited to the palliative care of patients with end-stage HF and severe respiratory distress.” As a nurse, we sometimes find ourselves turning to Morphine for AHF patients, and sometimes not. This article can help us understand what our physicians are thinking.
emDocs did a similar article, but with a bit wider scope. Entitled Myths in Heart Failure: Part II – ED Management, this article is less of a single article review, and more of a case study about patients presenting to an emergency department with acute heart failure with concurrent hypertension. This emDocs article reiterates the lesson from R.E.B.E.L. EM about Morphine potentially increasing mortality for AHF patients, but there is also an incredibly thorough list of clinical pearls for AHF with hypertension such as: guidelines for diuresis, use of nitroglycerine, the aforementioned consideration of opioids, and a very cool bit on ultrafiltration for patients refractory to front line diuresis treatment. (This is the second part of a series from emDocs, the first in the series, an article called Myths in Heart Failure: Part I – ED Evaluation was published in late July and is definitely worth a look.)
A very prescient article concerning pain management from Annuls Of Emergency Medicine has sparked some chatter on emDOCS.net. Anyone who still works in an ED that is handing out Dilaudid like candy knows that we are contributing in our own way to the opioid epidemic. emDOCS.net shares a great article by Doctor Casey Wilson on nerve blocks on their use in emergency departments for the control of pain. (If you don’t have access to Annuls of Emergency Medicine there is a great podcast that gives you a quite thorough roundup here.) According to Dr. Wilson nerve blocks can be used for “fractures, joint reductions, complex laceration repairs, chest tube placements and paraphimosis” and have been shown to be even better than opioids for some older patients with femur fractures. Not that I wish any nurse to be flooded with paraphimosis cases – but the article is pretty cool in that it explains the simplicity of ultrasound guided nerve block procedures while providing readers with some great PDFs. Another really interesting point, especially for those wanting to increase throughput in the ED, references (small) study done in 2008 in the American Journal of Emergency Medicine which showed ultrasound guided nerve blocks for upper extremity injury actually reduced the average length of stay in the ED by 3 hours! A very cool share and worth a link to your Sono Fellowship director.
CoreEM brings us a great review on Acetaminophen overdose written by Dr. Magda Robak. This is a simple but effective teaching module for anyone who wants to review the most common single cause of acute liver failure in the US. The article reviews the Acetaminophen nomogram and also shares a simple but fantastic spreadsheet that I think can be very useful, especially for nursing triage and early nursing care:
Justin Morgenstern writes for First10EM and shares with us a case study on post tonsillectomy hemorrhage. This is one of those great FOAM articles that really packs a huge punch. First10EM takes a patient that seems simple enough – a potentially severe oropharyngeal bleed – and takes a quick, but incredibly thorough dive, into treatment considerations in the ED. There is a lot here for the ED nurse to unpack. Some highlights from this article include:
- Simple positioning of the patient makes a huge difference in management in the first minutes of patient care.
- This patient may need a blood transfusion! IV Tranexamic acid may be called for, but surprisingly DDAVP can also be empirically used, as undiagnosed Von Willebrand disease is apparently somewhat common in these patients.
- To use an NG tube or not to use an NG tube – a great discussion between two ED docs.
- Stop the bleeding is the name of the game – but what to do first? Try direct pressure with McGill’s forceps, or stick your fingers in the mouth and try to apply direct pressure with some gauze soaked in tranexamic acid and DDAVP? If none of those options work, or if they are not plausible, should we try to apply pressure to the carotid?
- Intubation considerations, and which drugs might need to be prepped for induction.
- Simple recommendations are sometimes the most amazing – while we are all running around focusing on stopping the bleed, make sure you don’t forget to recommend antiemetics! The patient has probably swallowed a lot of blood and an episode of violent emesis can destroy any clot that is beginning to form, so make sure to remember that the patient needs a hefty dose of antiemetics.
The Bottom Line writes a critical review of the PAMPer paper that was published in late July by NEJM. This trial aimed to find a difference in survivability between air transported trauma patients that received either fluid crystalloid boluses, or plasma. This Bottom Line post outlines the strengths and weaknesses of the PAMPer trial, as well as a short review of other similar trials, and why PAMPer is potentially so impactful. The paper showed a significant increase in survivability in the plasma group, as compared to severe trauma patients who received fluid crystalloids only. The study shows a 10% drop in mortality with an intervention of 600cc of thawed plasma. This mortality drop is so dramatic for such a slight intervention change, that there is a portion in The Bottom Line review that states the “biological plausibility” is questionable, which seems to be a nice way of saying that there are probably biases within the study that partially explain the survivability differences.
Either way, the PAMPer trial in NEJM, and The Bottom Line’s review of the article, are great reads for anyone who works air emergency treatment and/or Level 1 trauma medicine. We’ve known for some time that flooding patients suffering from hemorrhagic shock with NS increases our coagulopathy, acidosis (NS has a pH of approx. 5.5) and (unless the fluid is warmed) the likelihood of hypothermia. Treatment for traumatic hypovolemia that shoves the patient into the “trauma triad” should probably be avoided – so expect more trials like PAMPer and, hopefully, a change in paradigm in pre-hospital treatment for hemorrhagic shock patients.
Kristina Kipp writes for EMCrit to bring us a short review on an article that discusses the efficacy differences between Propanolol v Metoprolol in electrical storm arrests. This article from the Journal of American College of Cardiology is another piece of literature we can add to our arsenal of emerging information concerning electrical storm arrest patients. If you haven’t worked an electrical storm arrest resuscitation, this is a great article to get a glimpse at what may be different than a typical ACLS code. If you have worked an electrical storm resuscitation, read this article to see if your resuscitation team is following the newest recommendations in this emerging sub-class of VF or VT arrest. There is a great list of references at the end of the EMCrit article that is worth a review as well.
The first time I’d ever read about beta blockers during cardiac arrest was in CanadiEM almost a year ago. The infographics in the CanadiEM article are really fantastic and outline the basics of the pathophysiological logic that is applied to electrical storm arrests and why these particular resuscitations are so much different than our typical AHA ACLS boilerplate codes.
Not that this is typical FOAM sharing but – just wanted to link an incredible article from MSF on America’s attempt to ignore evidence-based practice and obliterate global women’s health access. The “Global Gag Rule” will link the funding of HIV treatment, tuberculosis programs, mother and child care, and other global health initiatives to regressive and morally bankrupt dogma. Read here to learn more about the view from the ground. https://www.doctorswithoutborders.org/new-global-gag-rule-more-dangerous-ever
AHA Every Two Years
I have been an AHA instructor for about 4 years now. I can honestly say that most days I love to teach, but like most people, I have certain groups that I prefer. My favorite classes tend to be heavy with advanced practitioners and doctors – oh, and I love teaching residents. AHA material can get dry after a while, but a great practitioner can be a walking and talking reference manual for my recertification courses; full of facts, able to cite pertinent studies from memory and, at least in my experience, most are willing to drop some awesome pearls for the benefit of the other members of the class.
But not all classes are a pleasure to teach. Recently I taught a PALS class that didn’t go so well. One of my favorite EM docs had a group of 3rd year residents that required a short notice recertification. A multitude of factors made this class less than ideal, but the attending and the training center both bent over backwards to accommodate the graduating residents. Let’s just say that it was a less than positive experience. The only question during the class was “how long is this going to take?”. The students chatted through the video material, generally tried their hardest to not pay attention, and engaged in such loud side conversations during lecture that I had to ask them to stop multiple times. It was, to say the least, a very disappointing class.
But here is the thing: I get it. Doctors spend residency being grilled and challenged and tested and pushed. These particular residents have studied under incredible doctors and have done rotations at one of nation’s leading children’s hospitals. They are eager to move on to new attending jobs, they are exhausted from years of outrageous study, and have (nearly) completed the almost super-human task of becoming a licensed physician in the US. Beyond their level of training and preparedness, there is also the fact that AHA courses are, unfortunately, just another merit badge class. Hospitals use these courses to create the convenient situation where the hospital can outsource provider training and therefore all liability and responsibility. Why spend time and money investing in staff education and training when the AHA gives out these fancy cards? I get it – it can really feel silly taking
So why in HELL do my outrageously overqualified doctors need to take ACLS and PALS? Who thinks this is a good use of time?I’ve created a checklist. It isn’t exhaustive and it’s just my opinion, but if you are a graduating resident, or even an attending, and you can only be dragged kicking and screaming in order to recertify PALS or ACLS, perhaps this list might help put these AHA classes in a different perspective.
#4 – You Know What They Say About Assumptions…
I love my residents. They are smart. They are incredibly motivated. And most of all they tend to have a sincere passion for medicine. But not every doctor I’ve ever recertified has been well rounded. I wish I could say that docs don’t need this stuff, but unfortunately there are some attendings out there that haven’t really studied this material in years. I’ve been in codes with docs who do some downright goofy stuff. I’ve had residents shoot me incredulous looks while we try to pace asystole or take 5 minutes to sono a coding patients heart – all under the orders of an attending. So no, we can’t assume doctors are proficient in AHA standards and you can’t skip the class – even doctors should be reminded of the ECC standard every two years.
#3 – Sharing Is Caring
This is especially important if you are one of the few, or the only, doctor in the classroom. Not everyone has your education, knowledge and experience. Please be a positive resource to the rest of the class! As mentioned earlier, the AHA material can get pretty dry. If you have a good story that pertains to the information being taught, please chime in. Some of the best and most memorable teaching moments have come from doctors telling the class how something works, or doesn’t work. Assist the instructors with some of the material – for crying out loud help make this stuff interesting! You have better stories than us. Please share and make this a great educational experience for everyone.
#2 – Times They Are a-Changin’
The AHA guidelines are updated every 5 years. But our field changes daily. This is a fantastic opportunity to sit down with your fellow doctors and review basic guidelines. If the guidelines are similar to your practice than great! Let’s discuss the evidence in support of the AHA benchmarks, and even better, lets discuss why we don’t do what we may have done in the past. But sometimes things change faster than the AHA can keep up with. Pediatric therapeutic hypothermia anyone? Why or why not? Antibiotics for pediatric sepsis? But of course – but what cocktail are you using? How much, at what point, and what are the other options? These classes are an incredible opportunity to hone your skills. The resident class I taught argued with the PALS recommendation for fluid resuscitation for pediatric cardiogenic shock. One of the students went so far as to say that fluid was stupid and that dopamine was the only serious option. Maybe that is true, but maybe there are other opinions in the room. Is there controversy right now about dopamine versus norepinephrine in shock patients?* If you are too busy proving you are too smart for the AHA course material, we won’t ever get to opportunity to have some pretty important discussions.
#1 – It’s Not All About You
This is the most important thing to remember: the standards set forth by the AHA may seem simple, pedantic, or even incorrect to your well-educated medical mind, but this is what all of your nurses, NPs, and PAs know as gospel! Your education and experience doesn’t mean you’re beyond AHA standard – it actually means you are responsible for the entire resuscitation team’s grasp on the AHA standards. Stop recertifying AHA courses with the idea that the instructor is only here to test you out on your skills. You’re an attending. You think I’m impressed that you know that ventricular fibrillation needs defibrillation? Of course not. Take this recertification course as an opportunity to sit down and think about your team. This isn’t an 8-hour recertification class for you – this is a course where you get to familiarize yourself with your staff’s training standards. I know these classes may seem pedantic to you, but this might be the most cutting edge resuscitation science your nursing staff has ever been exposed to. Don’t like what you see? Fantastic! Ask me why the AHA isn’t talking about dual sequential defibrillation for VF electrical storm. Ask me about ECPR. Let us discuss where the AHA gets it right and where you think it might get it wrong. These classes offer you the opportunity to see how your staff is being trained. Don’t like what you see? Fine – take the class and then go talk to your nurse educator and come up with a plan on how to expand the curriculum. But you have to take the class. I get that the videos are boring, and I know you’ll pass the test and breeze through the mega codes. But you have an opportunity here to be a great healthcare leader so take it – you owe it to your patients, and you owe it to your team.
