Pulmonary Embolism Guidelines 2019

These are the 2019 European Society of Cardiology and European Respiratory Society Guidelines for the Diagnosis and Management of Acute Pulmonary Embolism. I must say, these are my favorite guidelines for PE and they came out just a few weeks ago on August 31st. It seems as if PE is just on every differential, as it respectfully should be, on anyone who is hypotensive with chest pain and short of breath. You definitely have to think about it, but that doesn't mean that everyone needs a CTA of the chest to rule it out. Many times a good history and physical can rule it out.

The images in this article is where much of the value is. The flowcharts simplify the thought process. I encourage those of you who have the ability to learn how to do some simple echocardiography to learn the skills of at least finding the windows. You'll be able to gain a TON of information just by laying the probe on the chest. This is one of those PDFs that you should definitely have accessible and refer to it often until you basically have these guidelines memorized.

A big hat tip to the authors. Again, I LOVE this paper.

NPO after Midnight: What do the guidelines say?

Is your shop still using strict NPO after midnight for its surgical patients? It’s time to talk to the powers that be to have this changed, supported by evidence, of course.

The controversy of “Strict NPO After Midnight” has been ongoing for many years now as the data has suggested it’s silly but still performed. Well, the American Society of Anesthesiologists put together a task force in 2017 to put an end to the silliness. Let’s try to make the horrible experience of being hospitalized a little less horrible for our patients. #endthenpo

A 🎩 tip to the authors. Happy Sunday!

Thiamine and Renal Failure in Septic Shock Patients

Every possible option to decreased morbidity, mortality, and costs are worth looking at in my book. The study that I am reviewing at this moment was published in 2017. I am ashamed that I had not run into it until today. It's challenging to stay up to date in everything. I digress.

Some would quickly bash this study for it being small (n=70) and a post-hoc secondary analysis of a pilot study. I am not going to do that. Why not? Well first of all, I do not participate in research myself. Just reading and enjoying these studies. Also, thiamine has no side effects described in the literature. Third, it is an inexpensive medication. Fourth, if it does turn out to decrease the incidence of acute kidney injury and the need for renal replacement therapy, aren't you going to feel guilty for not adopting these strategies for your patients? I hate resorting to that but my responsibility is for patients. What happens if this data is wrong? Nothing. What happens if this data is right and no one does anything for several years? Many patients may suffer.

This article is completely free and I encourage you to download it and read it for yourself. Amongst the points illustrated by the authors, they mention that it's not only perfusion that injures the kidneys during sepsis. There are other factors listed in the article. The way that it is postulated that thiamine works for these patients is by assisting in the mitochondrial dysfunction. Data that I have found not listed in this article shows that thiamine deficiency could have an incidence between 20-70% of critically ill patients. 

What they found was 21% of the patients in the placebo arm of the trial went on to need dialysis. Just one patient, or 3% in the thiamine group went on to require this. The authors note that acidosis was the primary indication for dialysis in 66% of the patients who required it. I personally would like to dig deeper into these numbers as there is some data that thiamine administration helps decrease lactic acidosis. 

This data should make you wonder if the strategy that many clinicians take of providing more IV fluids to patients whose renal function deteriorates is the correct strategy. Are we going to look in the mirror in a decade and want to punch our past selves in the face?

Thiamine, Ascorbic Acid and Corticosteroids: The Mechanisms by which they should help in Sepsis

Want some nerdy stuff? Well this is some nerdy stuff! I'm taking a nice deep look at this figure. I am not going to lie to you at this moment, October 19th, and tell you I know what all this means, because I don't. But people who are more intelligent that I am have suggested that these are the mechanisms by which thiamine, ascorbic acid, and corticosteroids should help in the treatment of septic patients. I have a lot to learn.

I hope I don't get dinged for copyright stuff but honestly if this offends you, let me know. I will take it down. I will likely go deeper into this article at a later time. Wanted to share this image with you right now, though.

Delirium in Mechanically Ventilated Patients: Let the Natural Light in!

I have great disdain for delirium. Natural light brings me great joy. Today, for example, the sun isn't shining bright. The day is cloudy and gloomy. I am, in turn, a little grouchy. Daylight savings is coming and I'm already upset about it. I can turn on the light but it won't be the same. This study was published today. How's that for so fresh and so clean?

Preventing and treating delirium is something we haven't quite figured out just yet. But studies like this one help us chip away at that giant piece of rock to eventually present a great sculpture. Bad analogy? Yep! In this study, the authors were curious to see whether patients having natural light would affect the incidence of delirium in patients who are on the ventilator (primary outcome). The secondary outcomes included the "duration of delirium, duration of coma, use of antipsychotics to treat agitation, the incidence of hallucinations, the incidence of self-extubation, duration of mechanical ventilation, ICU and hospital length of stay, ICU and hospital mortality."

This was a single centered trial with 195 patients. Out of their measured outcomes, they noted that the patients exposed to natural light had a reduced incidence of severe agitation (p=0.04). In addition, the patients exposed to natural light also had fewer hallucinations (p=0.04). Fortunately, this study is free and you can download it and read it yourself. I like natural light. It's free. It may not ameliorate delirium, but it is another tool in our tool belt to make these patients better.

Fluid Resuscitation of Trauma Patients: 0.9%NaCl (saline) or Plasma-lyte?

I am not a trauma surgeon. I am not a trauma physician. I do not take care of trauma patients in my current practice. I did several rotations in the trauma intensive care unit during my fellowship training but by know means am I going to pretend to have the knowledge that my colleagues who do that every day have. The study I am going to be discussing today is a pilot study.

The authors were concerned about the metabolic acidosis that occurs from the elevated chloride concentrations in 0.9% NaCl which is 154mmol/L. Remember, reference values in the lab for chloride levels are between 98 and 109mmol/L. Also, there is data suggesting that an increase in chloride levels by just 5mmol/L could have deleterious effects on our patients. This hyperchloremic metabolic acidosis is not something new, we've known about its effects on the kidneys for decades now. I guess we've just been ignoring it.

I am a fan of whole blood to resuscitate trauma patients, but I my knowledge on the matter is weak. At the time being, patients receive a significant amount of crystalloids for resuscitation. The authors chose to use NS and plasma-lyte due to the fact that lactated ringers is contraindicated with blood products as it allows the blood to coagulate as it goes in due to the calciums effect on citrate.

Surgeons are trained, from my experience, to focus on base excess. When a patient you're taking care of them is sick, and you're giving them a call to give them the heads up of what's going on, one of the first questions you need to be prepared to answer is "what is the base deficit"? Plasma-lyte is a balanced salt solution that I have reviewed numerous times on instagram, my website, and youtube. Plenty of resources out there from me explaining this fluid. This focus on base excess is why they made this

They ended up with 46 patients enrolled in the study.

Plasma-lyte corrected the base deficit faster than 0.9% NaCl. Primary outcome achieved. Patients reached and remained in their normal acid-base physiology longer.

They also found that 0.9% NaCl leads to hyperchloremic metabolic acidosis, decreased serum bicarb levels, and worse base deficit.

Patients also had increased urine output with plasma-lyte compared to saline solution. There is some concern about whether gluconate causes some sort of increased urine production but this is not specified in this paper.

Some institutions worry about the added cost of plasma-lyte, which is approximately $1 on top of the cost of NS or LR depending on the institution and their contract. This study showed that providing plasma-lyte kept serum magnesium levels closer to normal (p=0.007). If you are a bean counter, you could potentially save some money by using plasma-lyte due to less cost of magnesium replacement. I may be stretching a bit but at least I am admitting that I'm stretching. The patients needed about 4gm of Mg in the NS group and no replacement in the PL group. I take back the part of me stretching. The authors state that the difference at their institution of cost between NS and PL is $0.76. 2gm of magnesium is $5.19. That means that PL may end up saving money and additional testing.

All in all, this is a pilot study. I have not personally seen the actual study. If you all have, feel free to correct me. This is not a full free article, unfortunately.

BiPAP should not be used in Immunocompromised patients

This was a post-hoc analysis of the FLORALI trial that I have reviewed before on this medium. In that study they compared patients who had hypoxemic respiratory failure by putting them on 1:1:1 on high flow nasal cannula (HFNC), standard oxygen therapy, and non-invasive ventilation (NIV aka BiPAP).

My interest was piqued in trying to find out what they defined as immunocompromised patients. They looked at patient with hematologic and solid malignancies, AIDS, drug induced, and steroid related. The etiology for the respiratory failure in these patients was mostly for pneumonia, whether opportunistic etiology or not.

To make it simple, they found that patients treated wit HFNC did better than patients who received NIV regarding rates of intubation as well as mortality.
