Trauma Flashcards
subcutaneous emphysema = ?
trapped air or gas in layer under the skin
trapped air or gas in layer under the skin =?
subcutaneous emphysema
pt unconscious is what on GCS?
GCS of 8 or less
airway should be secured when (5)?
- pt is unconscious (GCS 8 or less)
- breathing is noisy or gurgly
- severe inhalation injury
- if pt needs a respirator
- B4 it becomes critical
pt w/ cervical spine injury + noisy breathing – what do you do first?
Secure airway first, then deal w/ cervical spine injury
Can orotracheal tube be inserted if pt has cervical spine injury?
Yes as long as can be done w/ head secured and not moved.
Another option is nasotracheal tube over a fiber optic bronchoscope
When do you use a nasotracheal tube over a fiber optic bronchoscope?
MANDATORY: when securing airway if there is subQ emphysema in the neck
Can be done for pts w/ cervical spine injury as well
what is a sign of major traumatic disruption of the tracheobronchial tree?
SubQ emphysema
SubQ emphysema is a sign of what?
major traumatic disruption of the tracheobronchial tree
Need airway but intubation not possible?! what next?
cricothyroidotomy!
why reluctant to do cricothyroidotomy before age 12?
bc of potential need for future laryngeal reconstruction
Satisfactory breathing or airway =?
Breathing: breath sounds bilaterally + good pulse ox
Airway: conscious, speaking w/ normal tone of voice
Clinical signs of shock
- low BP (
Main 3 causes of shock in trauma setting?
1) Bleeding (hypovolemic-hemorrhagic shock most common)
2) pericardial tamponade
3) tension pneumothorax
maj separator b/t shock caused by bleeding vs pericardial tamponade or tension pneumo?
Bleeding: Central venous pressure low –> veins flat
Peri/pneumo: CVP high (big distended head and neck veins)
shock caused by pericardial tamponade –> what signs?
- chest trauma
- CVP high (big distended head and neck veins)
- NO resp distress (diff from tension pneumo)
shock caused by tension pneumo –> what signs?
- chest trauma
- CVP high (big distended head and neck veins)
- Resp distress (diff from pericardial tamponade) –> one side of chest has no breath sounds and is hyperresonant to percussion
- mediastinum displaced to opp side of pneumo (tracheal deviation)
maj separator b/t shock caused by pericardial tamponade vs tension pneumo?
Pericardial tamp: NO RESP DISTRESS
Pneumo: resp distress w/ dec breath sounds 1 side + hyperresonant to percusion + tracheal deviation
Initial treatment for hemorrhagic shock w/ penetrating injuries ?
Surgical intervention to stop bleeding - since they are going to need surgery anyway, THEN volume replace
Hemorrhagic shock initial treatment usually?
Volume replace!!!!
VR w/ about 2L of Ringer lactate w/o sugar THEN PRBC until urinary output reaches 0.5 to 2mL/kg/h - while not exceeding CVP of 15mmHg
Hemorrhagic shock, what do you volume replace w/ first fluids or PRBC?
FLUIDS! about 2L of Ringer lactate w/o sugar then PBRC
In hemorrhagic shock volume replace w/ fluids and blood until what?
until urinary output reaches 0.5 - 2mL/kg/h – w/o exceeding CP of 15mmHg
In hemorrhagic shock volume replace w/ fluids and blood conscious not to exceed what?
CVP of 15mmHg
What is the preferred route of fluid resuscitation in the trauma setting?
2 peripheral IV lines - 16 gauge
