Thank you for tuning into the MaineCrit podcast and checking out the show notes!

Cardiac Arrest... When to Transport.

First, Transporting a patient in cardiac arrest is NOT beneficial unless the receiving facility is prepared and equipped to continue the resuscitation by treating reversible causes that EMS cannot. This is for EMS and ED providers.

The Case:

A 42 year old man awoke in the middle of the night with sudden, sharp chest pain and shortness of breath. He had no previous cardiac history and appeared very fit. His wife called 911. EMS arrived to find their patient in severe extremis and poorly perfused. He progressed to PEA arrest and the crew performed high quality CPR immediately. Advanced airway Obtained IV access. Several rounds of epinephrine. They worked the code for 20 minutes per protocol but did not get ROSC in the field so they called it.

The patient had minor surgery within the last week...

The hospital was half a mile away...

Take Home Points:

Most patients who suffer an OHCA will not survive intact unless ROSC occurs in the field.
There are reversible causes that most EMS systems cannot treat but an Emergency Department can.
There will be a small subset of viable patients that may be saved if transported expeditiously.
It is possible to transport patients in cardiac arrest safely with manual CPR and, perhaps someday, mechanical chest compressions and ventilation will open up additional options for longer transports to tertiary hospitals.
We must give every patient a chance for a successful outcome if such a chance exists. That is what Resuscitationist do! We must not give up unless there is nothing else that can be done.

Shock Essentials in 8 Minutes

2015-03-26T16:23:00.000-07:00

Shock: Inadequate perfusion at the cellular level.

“The rude unhinging of the machinery of life” ~ Samuel D. Gross

Adequate Perfusion requires:

The Pump (heart)
The Fluid (blood)
The Container (vasculature)
Air Exchange (oxygenation / ventilation)

The Pump

Adequate Cardiac Output
Stroke Volume X Heart Rate (4-8L/minute)
Affected by Preload, Contractile Force, and Afterload

The Fluid

Volume of blood must fill container

The Container

Vasculature is properly sized
Pre and post capillary sphincters at local level

Air Exchange

O2 into lungs and circulation
Elimination of CO2 and waste products

REQUIRES:
Adequate FiO2 and ventilation
Diffusion across alveoli / capillary membrane
Adequate number of RBCs
Efficient offloading to target cells

Stages of Shock

Compensated
Decompensated
Irreversible

Types of Shock

Hypovolemic
Cardiogenic
Distributive
Obstructive

Managing Shock

Primary Survey / ABCs
O2
BVM
C spine
Major bleeding
Supine / Keep warm
IV, monitor

Specific Treatments

Fluid challenge
Epi / Benadryl (anaphylaxis)
Chest decompression (tension pneumothorax)
Pericardiocentesis (cardiac tamponade)
Dysrhythmias (ACLS)
Pressors (fluids first)
Narcan (opiod OD)

Take Home Points

Shock: Inadequate perfusion at the cellular level.
If you think shock, your patient is already there.
Know and treat the root causes.
Set a target MAP.
Be aggressive!
