Study Notes
Trauma Patient Care
- The most common cause of death in the long term for trauma patients is multi-organ failure.
Blunt Trauma
- The spleen is commonly injured in blunt trauma.
- The LD50 for falls is approximately 25-30 ft (7.5-9 meters).
Vascular Access
- The preferred alternative route for intra-osseous cannulation in children under 6 is the anterior tibia.
Hemorrhagic Shock
- The initial fluid resuscitation for a patient in hemorrhagic shock is 1-2 liters of crystalloid.
Hemostatic Resuscitation
- The approximate ratio of RBCs:FFP:platelets in hemostatic resuscitation is 1:1:1.
- The indication for initiating hemostatic resuscitation is approximately 1-2 blood volumes or 4-6 units of blood products.
- Tranexamic acid is the medication that decreases fibrinolysis and reduces bleeding.
Damage Control Surgery
- "Damage control surgery" involves controlling hemorrhage, contaminant elimination, and temporary closure.
Diagnostic Peritoneal Lavage (DPL)
- An indication for performing a DPL is suspected intra-abdominal injury.
Abdominal Imaging
- FAST scan (focused abdominal sonography for trauma) can miss hollow viscous injuries.
- An abdominal CT scan should be performed following blunt trauma when the patient is hemodynamically stable.
- A CT scan can miss diaphragmatic injuries following blunt trauma.
Upper Airway Obstruction
- The most common cause of upper airway obstruction is facial trauma.
Fibrinolysis
- Tranexamic acid should be administered to a patient with evidence of hyperfibrinolysis.
Cutdown
- The preferred site for cutdown for venous access if large bore IV and central access are not possible is the groin.
Note: LD50 stands for Lethal Dose 50%, which is the dose required to kill 50% of the test subjects. In this case, it represents the height from which a fall would be fatal for 50% of individuals.
