Trauma & Burn Management in Anesthesiology
Which aspect of the Nurse Anesthesiology Resident (NAR)’ background will play an important role for managing patients with trauma and burn injuries?
The critical-care background of the Nurse Anesthesiology Resident (NAR) will play an important role for managing patients with trauma and burn injuries
Trauma & Burn Management in Anesthesiology
Trauma and burn patients require thorough assessment and immediate interventions due to
Pathophysiologic changes arising from traumatic injury
Trauma & Burn Management in Anesthesiology
The bodies response to trauma and shock has been described as a
Complex series of neural and hormonal reflexes that are induced by injury
Trauma & Burn Management in Anesthesiology
Why shoould a great deal of effort be utilized to stabilize Trauma and burn patients in the operating room suite?
Trauma and burn patients are some of the most challenging patients to take care of in the operating room suite
Trauma & Burn Management in Anesthesiology
The Nurse Anesthesiology Resident (NAR) must be aware that cell injury can occur from
Alteration of normal homeostasis
Trauma & Burn Management in Anesthesiology
There needs to be emphasis on providing adequate ventilation, oxygenation, and perfusion to these patients. Why?
Trauma patients suffer from shock and hypoxic states.
Trauma & Burn Management in Anesthesiology
Proper fluid resuscitation and blood administration is vital for survival in these patients. Why?
Trauma results in hemorrhagic blood loss or sequestration of extracellular fluid in the injured tissues
Loss of circulating volume triggers a response by low-pressure baroreceptors in the carotid arteries and aorta
Understanding the Trauma Patient
Trauma is classified at which type of medical situation?
Medical emergency
The trauma patient is considered a medical emergency and these patients may present totally obtunded. The NAR may not have any background information when caring for these patients
Understanding the Trauma Patient
Rapid sequence induction should always be utilized in this population. Why?
Full-stomach
All trauma patients are treated as a full-stomach and are high risk for aspiration.
Understanding the Trauma Patient
Compromised attempts to place an ETT - why?
Head injuries - cervical spine fractures - c-spine stabilization
These patients can also suffer from head injuries etc., which can compromise any attempts to place an ETT. Also, these patients may present with cervical spine fractures and require c-spine stabilization which could also impede ETT placement.
Understanding the Trauma Patient
How would the NAR go about intubating a patient with multiple facial fractures or the patient that has a completely deviated anatomy structure from injury?
Establishing an airway is essential for these patients
The NAR should consider utilizing a GlideScope or fiberoptic measures (if needed) to establish an airway
Understanding the Trauma Patient
Most patients come to the OR suite intubated. Whose responsibility is it to verify placement? How is this done?
Is the responsibility of the CRNA to verify placement by c_hecking breath sounds_ etc.
Understanding the Trauma Patient
In the case that a patient cannot be intubated by the primary anesthesia team, the surgery team should be on standby for
Tracheostomy
Understanding the Trauma Patient
Are there certain drugs to avoid in the trauma patient?

Understanding the Trauma Patient
Due to the emergency nature of these patients, many things are often overlooked which leads to
Life-threatening outcomes
Understanding the Trauma Patient
Due to the emergency nature of these patients, many things are often overlooked which leads to life-threatening outcomes. Some of the common overlooked diagnosis include
Pneumothorax
Cardiac tamponade
Cardiac contusion
Cervical spine injury
Open/closed head injury
Major blood vessel injury
Understanding the Trauma Patient
Resuscitation efforts should be prompt! Which time frome after traumatic injury often determines if a patient will survive?
The first 60 minutes after traumatic injury
Understanding the Trauma Patient
Resuscitation efforts should be prompt! The first 60 minutes after traumatic injury often determines if a patient will survive. This is known as:
The “golden hour”
Understanding the Trauma Patient
The chances of survival during the The “golden hour” are decreased in patients in
Hemorrhagic shock
Understanding the Trauma Patient
To provide some genuine advice I would advise all NARs to do what prior to intubating these patients?
Stabilize the cervical spine
Understanding the Trauma Patient
if no c-collar is in place
Stabilize and document
Have another provider to hold the neck
Have another provider to hold the neck if no c-collar is in place
Document this thoroughly in the chart to protect your license
Unfortunately, everything is blamed on “ANESTHESIA” in the OR suite and no NAR would like to be blamed from exacerbating a c-spine injury that was present in the first place
Please stabilize and document that intervention! ALWAYS!
Understanding the Trauma Patient
T/F: Trauma patients require both invasive and non-invasive monitoring
True
Understanding the Trauma Patient
Access required to assist with resuscitative efforts by the CRNA
Cordis (central venous sheath)
These patients usually require a cordis (central venous sheath) to assist with resuscitative efforts by the CRNA
Two large bore peripheral IVs
Although a cordis is frequently placed in these patients, a good rule of thumb is to place two large bore peripheral IVs
Understanding the Trauma Patient
Trauma patients require frequent monitoring of:
Urinary output
Chest tube output (if applicable)
ETCO2 monitoring
Temperature
Blood pressure via arterial line and NIBP
SPO2
EKG
Many trauma centers monitor CVP, CO etc. during the trauma process
Understanding the Trauma Patient
Advanced hemodynamic monitoring is used for:
To guide fluid/blood resuscitation
Understanding the Trauma Patient
There also needs to be frequent lab work completed to
Guide blood administration and
Guide usage of electrolyte replacement such as calcium, etc
In the OR; we usually do serial I-STATs every 30 minutes until patient is stabilized
Understanding the Trauma Patient
In the OR; we usually do serial I-STATs how frequently until patient is stabilized?
every 30 minutes
Most Common Problems in Trauma
- Hypotension
- Desaturation
- Hypertension
- Tachyarrhythmias and Brady-arrhythmias
- Sudden Cardiac Arrest
Most Common Problems in Trauma
Hypotension is u sually caused by
Hypovolemia
It is imperative that the CRNA or NAR initiate fluid resuscitation to combat hypotension
Vasoactive medications are usually utilized to help maintain adequate acceptable MAP goals
Be certain to rule out major vessel tears that can be the primary cause of hypotension
In rare situations, trauma patients are transported to the Interventional Radiology (IR) suite to both located and eliminate a major vessel tear
Most Common Problems in Trauma
In rare situations, where are trauma patients transported to both located and eliminate a major vessel tear?
Interventional Radiology (IR) suite
Most Common Problems in Trauma
Desaturation - When desaturation occurs check for
Adequate FIO2, ventilation, and perfusion
Look for signs of a pneumothorax (distended neck veins, tracheal deviation)
Rule out pulmonary contusions, mucous plugs etc.
Patient may require a STAT chest x-ray to rule out more pertinent issues
Most Common Problems in Trauma
Hypertension - When do Trauma Patients frequently become hyperdynamic?
After resuscitation
Most Common Problems in Trauma
How is Hypertension is mostly treated?
By deepening the anesthetic or offering opioid therapy
Most Common Problems in Trauma
What should be considered first when these issues Tachyarrhythmias and Brady-arrhythmias arise?
Hypoxemia and hypercarbia
Monitoring lab work for electrolyte imbalances should also be utilized for prompt correction
Most Common Problems in Trauma
Sudden cardiac arrest is often a strong indication for
Open thoracotomy
To inspect the heart for pericardial tamponade
Surgeons often have to open the chest and perform a cardiac massage
Most Common Problems in Trauma
In addition to monitoring lab work for trauma patients; the CRNA must pay close attention to blood glucose levels - why?
Trauma patients may need insulin to bring glucose levels to an acceptable level in the OR
On the other hand, trauma patients rapidly consume their gluconeogenic substrate which causes significant hypoglycemia to occur
However, these patients are more likely to experience hyperglycemia than hypoglycemia
Data has shown that preexisting hyperglycemia increases damage of ischemic/hypoxic events
Most Common Problems in Trauma
What are the most common causes of coagulopathy in the trauma patients?
Dilutional thrombocytopenia
Hypofibrinogenemia
Most Common Problems in Trauma
Dilutional thrombocytopenia is the most common cause of coagulopathy in the trauma patient, followed by hypofibrinogenemia. These conditions are treated with
Platelets, FFP, and cryo as indicated
In the OR we use the level one infuser via massive transfusion protocol (MTP) [1:1 PRBCs/FFP] until the patient is stabilized
Most Common Problems in Trauma
T/F: Remember when giving platelets to never run them through the warmer
True
Never run them through the warmer!!!
