🚨New #OpenAccess Article 🚨

New review article highlighting key points in fluid resuscitation for septic patients, on the wards or perhaps on the verge of needing ICU.

I admit, not without agenda (⬇️fluid overload)

Freely available through Sept 2: sciencedirect.com/science/articl…
A few editorial points:

Most of the evidence presented involves critically ill patients, but the lessons shouldn’t much differ if you have a hypotensive/malperfused patient on the wards.

Without the benefit of vasopressors, it’s difficult to determine how to safely resuscitate
We advocate for a hemodynamically-targeted approach to fluid resuscitation. It’s difficult to assess fluid responsiveness in the ICU, moreso on the wards.

(Proposed approach, not prospectively validated)
Given potential harms of fluid overload, this is a situation to consider early ICU transfer rather than continued boluses that the patient “seems” to respond to briefly.

As intensivists, we need to be better advocates for patients in this situation, as well as their team
Once upon a time (or currently in some places), a patient needed to “prove” their need for ICU by having received extensive fluid loading.

Hopefully we are moving out of this paradigm
To this point, maintenance fluids in wards patients without ongoing fluid losses ought to be avoided.
I’m sure this work will generate some strong opinions, but overall we feel this is a good starting point for reconsideration of fluid management in septic patients on the wards.

Tempted to tag many hospitalist friends, but I’d rather you discover it on your own!
Here’s hopefully a better permanent link:

Phenomenally lucky to have @AndreMansoor speak at our Critical Care Conference today on Diagnostic Reasoning. Image
A few take aways that resonated:

1) A thorough diagnostician doesn’t ask every question/ROS or perform every exam maneuver

2) Order tests/labs in anticipation of a finding (rather than a shotgun “see what comes up” approach)
3) “Everybody knows how to order a cardiac MRI but not how to examine neck veins” 🔥

4) Of course, the frameworks: amazon.com/gp/product/149…

Reflections on a cricothyrotomy:

I wanted to share my personal first experience performing this high-acuity and rare procedure, in the hopes that others will learn from it.

Consider this part reflection, part tweetorial

A team member called me to say “We need you at the bedside NOW”, without further details, but with a higher sense of urgency than I’m used to from this person, so I ran to the bedside.

In fact, shortly after arriving my watch asked me if I was starting to exercise
Intentionally obfuscating details about the patient, suffice it to say there was a major arterial bleed into the oropharynx which developed without warning and lead to prompt cardiac arrest.

🚨 Multi-part case #Tweetorial
24y man no PMH. 3-4 days myalgias, freq diarrhea. 2L saline given on med floor -> hypox/tachypnea. COVID pend.
A 👍
B RR30-34, SpO2 92% 5L NC
❤️ MAP 90, HR 110s ->150s over 12 hrs
D Avpu
E Anxious
L CRP 58 (ULN 0.9), Cr 1.4 (no baseline), Lact 4.8 Image
WOB is moderately elevated.

What diagnostic manuever do you think is most important at this point?
Unlike most MC questions, you also get to choose a therapeutic maneuver while dx is happening. What's your first choice?

More case details to follow tomorrow!

🚨Crashing Patient Case🚨

72 yo ♀️ to ED with syncope, hypotension. Intubated for hypercap/hypox resp failure. Hypotensive post, tx to ICU.

A Tubed
B FiO2 1.0, 10 ml/kg Vt
❤️ MAP 70 -> 50 -> 30 in mins
D sedate, +cough
E Leaky 22g PIV
U n/a
L WBC 35k, lact 1.7, UA+CXR shown
First step?
My team is very adept at CVCs, but we go for the IO (1 min to insert vs 10, and much higher first past success doi.org/10.1097/ccm.00…)

More on IOs from LITFL litfl.com/intraosseous-a…

Also, the vent is alarming for high peak pressures (45 cm H2O consistently). What next?

On arrival to the ICU he develops shock requiring vasopressors. Abx staretd. Mottling on knees. What's the next step?

Case details to follow tomorrow!
ABG in ED 7.38 / 34 / 70 / 21 on 5L NC in ED, I did not repeat on HFNC.

IL-6 level 120 (normal: <6)

Interesting issue in mechanical ventilation of #COVID19 patients, each one here after >10 days of mechanical ventilation.

How might we monitor for development of this? Time to pay attention to resistance, oft neglected in the age of COVID #ARDS...

First step is to examine the flow waveform. In this case a patient in volume control, to observe how passive expiration is changed by changing time constant.

More on time constants here: derangedphysiology.com/main/cicm-prim…
A faster time constant is associated with decreased compliance (increased elastic recoil). The opposite is seen with airway resistance.

In these cases we often see the expiratory phase on the flow diagram *not* return to baseline before the next inspiration is initiated
