ICU, OR, and Cardiac Trauma Flashcards
____ is a condition in which the body’s organs and tissues don’t get adequate oxygen supply.
Hypoxia
____ is inadequate perfusion of vital organs.
Shock
Hypotension is a systolic BP od < ____mmHg.
90mmHg
The biggest reason for hypotension in critically ill patients is due to ____ and ____.
Hemorrhage and hypovolemia
Hypotension is seen on the echo as a small LV with ____ motion.
Hyperdynamic
The most obvious cause of hypoxia is a ____.
Pulmonary embolus
What should you do before and after MV repair?
- Preop: assess severity of valve problem & check if other valves need repaired.
- Post op: determine if any MR is present and how much.
- Make sure that the repair didn’t cause MS.
- Trace the waveform for a mean pressure gradient.
- When a MV replacement is done, check for obstruction in the LVOT from the struts.
What should you do before and after AV repair?
- Pre-op: measure the LVOT diameter (to determine size of valve)
- Post-op: look for AI, AS and SAM which can be more of an issue with AV repair.
If ____ is present in the LV it could go into the coronaries and cause an embolic event and possibly an MI.
Air
They get rid of the air while the pt is still partially on ____.
Bypass
An ____ is when a probe/catheter is placed into the heart during a cath procedure.
Intracardiac echo (ICE)
____ chest injuries are more common than ____ injuries.
Blunt; penetrating
2 major life-threatening consequences of cardiac trauma:
- Hemorrhage
- Cardiac Tamponade
Most common cause of blunt chest injury:
Steering wheel contusion from high speed MVA
Injuries from blunt chest trauma will include those of the:
Myocardium, pericardium, endocardial structures, and coronary arteries
____ often follows blunt chest trauma and is indicative of cardiac injury.
Pericardial effusion
Effusions due to trauma are frequently ____
Bloody
Cardiac contusion is a bruise to the ____.
Myocardium
Cardiac contusion is most commonly caused by:
High speed MVA
____ may look similar to an MI, except damage is usually “patchy”.
Cardiac contusion
Aortic ____ is usually fatal.
Laceration
Approximately ____% of patients with aortic rupture survived for more than an hour after trauma
