Shock Flashcards
In a trauma patient, what do we use for fluid resus?
Blood
What is the aim of fluid resus in a septic patient?
Help to maintain volume in intravascular space
Flush out toxins
Do you do fluid resus in a cardiac arrest?
Depends on the cause e.g hypovalaemia
What is meant by a non responder patient in relation to trauma shock?
Patients who have persistent state of shock despite resuscitative efforts. These are the sickest patients
What is meant by a transient responder patient in relation to trauma shock?
Patients who initially improve following resuscitative efforts but then subsequently deteriorate. They often have intracavity blood that will require operative management.
What is meant by a
responder patient in relation to trauma shock?
A patient who rapidly correct their shocked state with minimal intravascular replacement. These patients do not have ongoing bleeding, or bleeding that has been tamponaded.
What are the 3 distinct groups that trauma shock patients are categorised by dependent on their response to resuscitative manoeuvres?
Responders, transient responders and non responders
How might a patient with advance stages of shock present?
Unconscious and lack the ability to protect their airway
High RR as the respiratory system attempts to correct the metabolic acidosis associated with tissue hypoperfusion
Cool clammy skin
Altered sensorium
Tachycardia
Hypotension
What are the initial events that lead to shock?
Loss of circulating blood volume
Tissue trauma
Pain
Hypoxemia
Hypercarbia
Hypoglycaemia
What is traumatic shock?
Body’s response to trauma, think hateful 8
What is obstructive shock?
A physical obstruction reducing blood flow, causing a reduced cardiac output e.g PE, tamponade
What is inflammatory (septic)
shock?
Infection causing problems in how cells work leading to a drop in BP
What is neurogenic shock?
Damage to the nervous system after spinal cord injury that causes the nervous system to have trouble keeping HR, BP and temp stable
Doesn’t occur in injuries below T6
What is cardiogenic shock?
The heart suddenly can’t pump enough blood to meet the body’s needs
What is hypovolaemic shock?
Sever blood or fluid loos that causes the heart to be unable to pump enough volume around the body
