Shock and Bleeding in the Trauma Patient

April Morgenroth RN, MN

Shock Defined

Shock: A state where the body’s organs are not sufficiently perfused with oxygenated blood.

Key Points

Pressure = amount of stuff in a given space

Remember: Hypoperfusion= oxygenated blood not getting where it needs to go

Blood is driven by pressures

Battlefield Awareness: Recognizing Shock

Types of Shock:Distributive:

NeurogenicSepticAnaphilactic

Cardiogenic:MI, Cardiomyopathy, tampenade

HypovolemicRelative vs. Absolute

Distributive Shock

Insult

Vasodilation

Same Stuff/ More Space

Hypotension

Causes of Distributive Shock

• Neurogenic: – Head injuries– Spinal Cord injuries– Pain and drugs

• Septic:– UTI– SIRS – Bacteremia

• Anaphylactic– Bee stings– Drugs– Foods

The Circulatory SystemReview

The circulatory system facilitates the transportation and exchange of oxygen, carbon dioxide, and nutrients.

Blood

Red blood cells: Carry oxygen to cell and carbon dioxide away from cells

White blood cells: Play a role in fighting infection and protecting the body against pathogens

Platelets: Help the body form clots to repair damage done to the blood vessels.
