What is #Pre-Hospital #CriticalCare? A short 🧵:

Also referred to as Pre Hospital Emergency Medicine (PHEM), #PHEM is “that area of medical care required for seriously ill or injured patients before they reach hospital (on-scene) or during emergency transfer to hospital” 1/11 Image
PHEM in Ireland is practiced by a small number of doctors who respond voluntarily to taskings from @AmbulanceNAS to serious illness or injury.

These doctors are supported by charities like @WicklowRR.

Other groups include: @WestCorkRR @EastCorkRR and @CRITICALcharity 2/11 Image
PHEM doctors complement the work of @PHECC practitioners in @AmbulanceNAS @DubFireBrigade and many other emergency agencies.

PHEM doctors can provide additional interventions, medications and decision-making, or simply be the closest resource to a time critical emergency. 3/11 Image

ICU pictorials: A patient was admitted for "weakness". Unimpressive vitals / phys exam / labs. A few days later because of temp 101 F, a fever w/u was initiated. Due to "SOB", a CT chest angio was done:

1/n: Thread of interesting ED #POCUS case. F/70+, known epigastric hernia (relapsed post repair years ago). Repeated vomiting since 1 week. Labs and plain x-rays - ImageImage
2/n Distended stomach noted on #POCUS -
3/n Clinically the hernia appeared to be reducible. However, #POCUS demonstrated obstruction of gastric outflow due to incarcerated portion of gastric antrum.

Deresuscitation has become more and more ubiquitous within ICU practice. But what tools can we use to do it? Over the next 2 Tweetorials, i’ll explain some pharmacological methods. Focussing on the JICS mix!

My talk from #ACCS2023

#FOAMed #POCUS #FOAMcc #medtwitter
The brilliant paper in question is well worth a good read through. For both its novel description of combination diuretic therapy, and its golden descriptions of simple and complex fluid/renal physiology.

Here’s the infamous JICS mix:… Image
We know, universally, oedema on the ICU is contentious. Early goal directed therapy trials after Shoemaker, all demonstrated worse outcomes. Why?🤔

There were signals towards positive fluid balance and probably states of venous congestion in the treatment arms.

A summary thread from the great Emergency Medicine Australasia issue I finally read on the plane; @EMAJournal #foamed

Thom study in EMA: patients with unstable cervical #fractures can sit (29%), walk (63%), lack midline tenderness (27%), and have delayed presentation (20%).
@EMAJournal #emergencymedicine

surf injuries were mostly lower c-spine

NEXUS underperformed compared to Canadian C-spine.

#drowning and cervical CTs are not inextricably linked: don't automatically image unless signs of axial loading/very specific concerns
@EMAJournal [my $0.02 on immobilising (virtually) anyone prehospitally: cervical immobilisation is a myth: collars don't actually immobilise, and 'immobilisation' doesn't actually prevent neurological *does* however harm (eg aspiration and other harms)]

M mode in echo is a bliss
Gives a grt temporal resolution
ie.,Relation of structures with respect to time.
At times it's difficult to follow motion of valves in 2D
In this thread let's see about Mitral valve M MODE
A normal mitral valve M mode
#echofirst #pocus @pocus_today Image
E &A are two positive waves due to opening of mitral leaflet
E - Early diastole due to LA LV gradient
A - Late diastole due to atrial contraction
C- closure of Mitral valve
D-End systole / Begining of diastole
B-Due to Elevated LVEDP in late diastole ImageImage
Mitral stenosis:
The EF slope is reduced
In earlier times Mitral stenosis severity was assessed with shallowness of the slope. More flatter the slope is , more severe the MS
This semiquantitative method of assessing severity is not used nowadays
A wave is lost in MS with AF Image

Also, good to be aware while performing #POCUS
Other relevant illustration: Left ventricular circulatory support devices

Reason # 76587 why lung #pocus is important: it can often give more information than CXR or CT Chest can. Case in point:

Elderly female on methotrexate and prednisone presenting with fever and cough.

Initial CXR:
Read as "Bibasilar atelectasis." She was started on antibiotics. The following morning had abdominal pain and CT chest abdomen and pelvis ordered. CT chest seen here:
Grossly does not look too impressive. Radiologist read it as "no consolidations, scattered linear opacities." That afternoon seen by a physician skilled in lung #pocus. Left lung lateral lung seen here

Patient came to the ICU intubated, sedated, on pressors & antibiotics for PNA. Next step: POCUS. PLAX looked "weird", so Doppler and "zoomed" views were recorded:

#POCUS question of the day?
1. What does this image show, and what mode of ultrasound was used to obtain it?
2. What is the E-point?
3. What is the A- point?
4. What is EPSS, and why do we use it?

Scroll down to learn how to interpret the image.
Answer 1: The image above shows the mitral valve in M mode taken during the PLAX view at the MV leaflet tips.

Answer 2: During early diastole, the leaflets separate widely with the maximum early diastolic motion of the anterior leaflet termed the E-point
Answer 3: During atrial contraction, the leaflets move towards each other in mid-diastole (F-point =diastasis) and then separate again with atrial systole, thus resulting in the late diastolic peak or the A point.

Guideline summary for #ED docs on early pregnancy loss/miscarriage:…
10% of all #pregnancies end in #miscarriage, though the rate approaches 80% by maternal age 45yrs.
Half of early pregnancy loss (AKA miscarriages) are due to chromosomal abnormalities. 🧵
Crown-rump length (CRL) 7mm or greater and no heartbeat. Mean sac diameter (MSD) 25mm and no embryo.
Each one is an #ultrasound feature diagnostic of early pregnancy loss.
80% of patients with early pregnancy loss can be safely managed with an expectant management (watch and wait) approach.
Relatively few miscarriages will require ED care; most of these will involve significant and symptomatic haemorrhage or infection.
