thoracotomy is indicated when output exceeds 1500 mL within 24 hours, THE
INDICATIONS for thoracotomy after traumatic injury typically include shock, arrest
at presentation, diagnosis of specific injuries (such as blunt aortic injury), or
ongoing thoracic hemorrhage. - correct-answer - Indications for thoracotomy
sx can be slow and gradual and silent. hypotension, tachycardia, arrhythmias and
dysrhythmias, visible trauma, distended neck veins, muffled heart sounds, and
other signs of shock.
Note: rapid deceleration - correct-answer - blunt cardiac injury s and sx
1.Metabolic acidosis is corrected by control of hemorrhage and admin of fluids
and blood

2.The degree of metabolic acidosis is measured by the base deficit from the abg's.
The base deficit helps estimate level of perfusion and pt's response to
resuscitation - correct-answer - Acid base balance, base deficit and shock
1. Normal -2 to 2
2. Mild -5 to -3
3. Moderate -9 to -6*** (-6 or more indicates severe injury and significant
mortality)
4. Severe -10 or more - correct-answer - Base deficit chart 1. normal 2. mild 3.
moderate 4. severe
Lactate levels help determine organ perfusion. Obtain lactate levels and correct to
less than 2 - correct-answer - Lactate levels and shock
an abnormality of the circulatory system that results in inadequate organ
perfusion and tissue oxygenation. Reduced tissue perfusion causes cellular

hypoxia-> cellular conversion from aerobic to anaerobic metabolism ->leads to
accumulation of lactic acid -> metabolic acidosis - correct-answer - define shock
Urine output measures organ perfusion and adequate resuscitation
Adults- 0.5 ml/kg/hr
Peds- 1 ml/kg/hr
baby- 2 ml/kg/hr - correct-answer - Urine output and hypovolemic shock
- correct-answer - epidural hematoma
the airway with cervical spine control - correct-answer - When multiple victims
are present at the scene of a major motor vehicle crash, the highest priority is
given to
