Question

A young woman is brought to the emergency department by ambulance after a severe motor vehicle accident. She is unconscious. Her blood pressure is 64/40 mm Hg; heart rate is 150 bpm. She is intubated and is being hand-ventilated. There is no evidence of head trauma. The pupils are 2 mm and reactive. She withdraws to pain. Cardiac examination reveals no murmurs, gallops, or rubs. The lungs are clear to auscultation. The abdomen is tense, with decreased bowel sounds. The extremities are cool and clammy, with thready pulses. Despite aggressive blood and fluid resuscitation, the patient dies. Questions: A. What is the likely diagnosis? Why? B. What are the major pathophysiologic causes of this condition? Which was likely in this patient? C. What pathogenetic mechanism accounts for this patient's unresponsiveness? For the cool, pale extremities?

Step 1

- The patient presents with extremely low blood pressure (64/40 mm Hg) and a high heart rate (150 bpm), which are indicative of shock. The fact that she is unconscious and has cool, clammy extremities with thready pulses further supports this diagnosis. The tense Show more…

Transcript

00:01 The question that is given over here, it is a kind of case study.

00:04 The question says that a young woman is brought to the emergency department by ambulance after a severe motor vehicle accident.

00:21 She is unconscious.

00:23 Also her blood pressure is 64 per 40 mm of mercury and her heart rate is 1 .4 .4 .40 m.

00:34 Of mercury and her heart rate is 1 .5.

00:40 Is t bpm beats per minute and she is intubated and is being handled ventilated.

00:48 There is no evidence of head trauma.

00:51 The pupils are two m .m and they are reactive.

00:55 She withdraws to pain.

00:57 Cardiac examination reveals no monomers, gallops or ruffs.

01:01 So the lungs are clear to us.

01:03 Asculation, the abdomen stands with decreased war sounds.

01:07 The extremities are cool and clammy with the 3d pulses.

01:10 Despite the aggressive blood and fluid resuscitation, the patient dies.

01:15 So we have to diagnose what may be the diagnosis.

01:29 So the diagnosis may be we have to access the heart rate, blood pressure, the central venous pressure, the catheterize the bladder to assess the urine output.

01:46 The renal function test rft should be taken.

01:48 1, creatine, each and every test should be taken.

01:56 The liver function test should also be taken...
