3. Half-Day Hospitalist POCUS: Learn absolutely necessary skills for the day-to-day management of your hospitalized patients. It doesn’t matter how good a clinician you are, with ultrasound you will be a better one. Learn from a world-class clinician faculty how to assess the IVC for a number of clinical scenarios, how to assess lungs, do basic cardiac views, diagnose or rule out hydronephrosis, and safely tap ascites or pleural effusions.

Cutting edge today, standard of care tomorrow…

Faculty: Rola, Ajmo, Haycock, Baker, Olusanya

Practice on state-of-the-art simulators, normal volunteers and volunteer patients with true pathology.

Your patients need you to know this.

Limited to 30 participants so that your hands on and faculty experience is maximized. 300$CAN/250$USD

 

4. Half-Day Critical Care Procedures: If you are not already familiar with these key procedures any resuscitationist should have in their pocket, don’t miss this course. We’ll go over thoracic pigtail insertion, bedside percutaneous tracheostomy and emergency surgical airway, using manikins and natural simulators. Plenty of practice, until you’re comfortable with the techniques. By the end of this activity, participants should be able to independently insert pigtail catheters and perform an emergency surgical airway, and be able to perform a percutaneous tracheostomy with the backup and supervision of an experienced operator.

Faculty:  Ajmo, Farkas, Tremblay

Limited to only 20 participants, so don’t wait too long! 300$CAN / 250$USD

 

 

 

5. Brazilian Jiu-Jitsu for MDs: Nope, you didn’t accidentally click on a link. This is part of the pre-conference day. What does it have to do with medicine? A lot. With life? Everything. If you’re already got mad mat skills, come join us for a couple hours of fun. If not, treat yourself to an introduction into a martial art, a sport and even a lifestyle that cultivates physical and mental health like no others. The rest of the conference will change your practice, but this workshop might change your life.

Faculty: Spiegel, Rola, and some guest stars!

No experience necessary, only interest and enthusiasm.

It’s a bit too early to be sure who, but expect to have some interesting surprises as to who your instructors might be…

…oh, and acute care docs should find something in the words of Rickson Gracie, one of the legends of jiu-jitsu:

Limited to 30 participants, registration fee TBA, and will open on november 1st. You can reserve your spot in the meantime by emailing hospresusconference@gmail.com.

 

So we are really looking forward to these courses. It’s a great opportunity to pick up some important skills and have plenty of time with some awesome instructors, all of whom are hoping to share as much clinical knowledge as possible.

Mark your calendars! Please email hospresusconference@gmail.com with any questions!

A Primer on Pigtail insertion. #FOAMed, #FOAMcc

So I recorded this for our incoming residents to Santa Cabrini ICU, whom we expect to become well versed in this procedure by the end of their rotation with us. The difference between a smooth and simple insertion – best for both patient and operator, is in the little details.

Figured I might as well put it up on #FOAMed in case anyone else may benefit!

Here is the podcast:

 

And here is a video displaying the technique.

The Right Stuff: A Nutrition Discussion with UFC Pro Aiemann Zahabi (@aiemannzahabi), #FOAMed

 

So had a chance to catch up with my friend Aiemann last week to finally re-record our lost conversation, which was even better since, in the interim, he has taken up intermittent fasting (IF), and has some follow-up on his experience with it!

More to come on this, slowly but surely!

Love to hear others’ thoughts and ideas!

 

cheers

The Resus Tracks 06: Farkas (@Pulmcrit) on Shock Perfusion and Infrared Tech! #FOAMed, #FOAMcc

So I had the chance to catch my friend Josh today, and, as always, he had some unique insights to contribute.

 

I really like the IR idea from the standpoint of objectivity and reproducibility. At first it sounded like a fancy (and fun, of course) way to check skin temperature as I routinely do, but the ability to objectify from doc to doc could be really interesting. Will get on that with my colleagues in my unit. We’ll see what we can come up with in the next months!

 

Love to hear from some others trying to tweak and optimize their resus!

 

cheers

Shock Macro and Micro-circulation: Piecing things together. (Part 1) #FOAMed, #FOAMcc

 

So I have really, really enjoyed the discussions I had with these bright people on shock circulation:

Segun Olusanya (@iceman_ex) Resus Track 2

Rory Spiegel (@EMnerd) Resus Track 3

Korbin Haycock (tell him to get on twitter) Resus Track 4

Jon Emile (@heart-lung)  Resus Track 5

 

Some take home points so far:

I think that more questions than answers truthfully came out of this, and that is really the best part. But lets see what the common agreed upon thoughts were:

a. the relationship between the MAP and tissue perfusion it quite complex, and definitely not linear. So scrap that idea that more MAP is more perfusion. Could be more, same, or less…

b. you can definitely over-vasoconstrict with vasopressors such that a increasing MAP, at some point, can decrease tissue perfusion. Clinically, we have all seen this.

c. no matter what you are doing theorizing about physiology and resuscitation, THE MOST IMPORTANT IS TO CONTROL THE SOURCE!

 

Some of the interesting possibilities:

a. Korbin sometimes sees decreasing renal resistive indices with resuscitation, particularly with the addition of vasopressin.

b. the Pmsa – can this be used to assess our stressed volume and affect our fluid/vasopressor balance?

c. trending the end-diastolic velocity as a surrogate for the Pcc and trending the effect of hemodynamic interventions on tissue perfusion.

This stuff is fascinating, as we have essentially no bedside ability to track and measure perfusion at the tissue level. This is definitely a space to watch, and we’ll be digging further into this topic.

 

Jon-Emile added a really good clinical breakdown:

I think one way to think of it is by an example. Imagine 3 patient’s MAPs are 55 mmHg. You start or increase the norepi dose. You could have three different responses as you interrogate the renal artery with quantitative Doppler:

patient 1: MAP increases to 65 mmHg, and renal artery end-diastolic velocity drops from 30 cm/s to 15 cm/s
patient 2: MAP increases to 65 mmHg and renal artery end-diastolic velocity remains unchanged.
patient 3: MAP increases to 65 mmHg and renal artery EDV rises from 10 cm/s to 25 cm/s

in the first situation, you are probably raising the critical closing pressure [i know i kept saying collapse in the recording] relative to the MAP. the pressure gradient falls and therefore velocity falls at end diastole. one would also expect flow to fall in this case, if you did VTI and calculated area of renal artery. in this situation you are raising arteriolar pressure, but primarily by constriction of downstream vessels and perfusion may be impaired. ***the effects on GFR are complicated and would depend on relative afferent versus efferent constriction***

in the second situation, you have raised MAP, and probably not changed the closing pressure because the velocity at the end of diastole is the same. if you look at figure 2 in the paper linked to above, you can see that increasing *flow* to the arterioles will increase MAP relative to the Pcc [closing pressure]. the increase in flow raises the volume of the arteriole which [as a function of arteriolar compliance] increases the pressure without changing the downstream resistance. increasing flow could be from beta-effects on the heart, or increased venous return from NE effects on the venous side activating the starling mechanism. another mechanism to increase flow and therefore arteriolar pressure relative to the closing pressure is the provision of IV fluids.

in the third situation, MAP rises, and EDV rises which suggests that the closing pressure has also fallen – thus the gradient from MAP to closing pressure rises throughout the cycle. how might this happen? its possible that raising the MAP decreases stimulus for renin release in afferent arteriole, less renin leads to less angiotensin and less efferent constriction. thus, paradoxically, the closing pressure falls with NE! another possibility is opening shunts between afferent and efferent arterioles [per Bellomo]. as above ***the effects on GFR are complicated and would depend on relative afferent versus efferent resistance changes***

 

This is really, really interesting stuff. So in theory, the MAP-Pcc gradient would be proportional to flow, so if we can estimate the direction of this gradient in response to our interventions, we may be able to decrease iatrogenism. I’ll have to discuss with Jon and Korbin which arterial level we should be ideally interrogating…

More to come, and next up will be Josh Farkas (@Pulmcrit), and I’m sure anyone following this discussion is looking forward to what he has to say. I know I am.

cheers!
