complications

Question 1

a line complications

Answer 1

distal ischemia 2/2 thrombosis, proximal emboli, prolonged shock
pseudoaneurysm
av fistula
hemorrhage
hematoma
infection
skin necrosis
peripheral neuropathy and damage to adjacent nerves
misinterpretation of data
cerebral air embolism 2/2 retrograde flow with flushing

Question 2

central line complications

Answer 2

mechanical injury: arterial, venous, nerve injury, cardiac tamponade

respiratory compromise: airway compression by a hematoma and pneumothorax

arrhythmias

thromboembolic events: venous or arterial thrombosis, PE, catheter/guidewire embolism

Infectious: infection at site, catheter infection, blood stream infection, endocarditis

Misinterpretation of data

Question 3

PAC complications

Answer 3

venous access/PAC placement: arterial puncture, arrhythmias (RBBB, CHB, vfib/tach), postop neuropathy,, pneumo, air embolism

catheter residence: catheter knots, infection, thrombophlebitis, thromboembolism, pulmonary infarct, endocarditis, valvular injury, PA rupture, PA pseudoaneurysm

death

misinterpretation of data

Question 4

hyperglycemia complications

Answer 4

increased short term and long term morb and mort
wound infections
poor wound healing
worsened neurologic outcome

Question 5

severe HTN can cause

Answer 5

MI (2/2 increased afterload)

cerebral infarction

Question 6

autonomic neruopathy concerns/risks

Answer 6

• aspiration risk (gastroparesis)
• hypotension (Esp post induction 2/2 impaired peripheral vasoconstriction and baroreceptor function
• silent ischemia
• intraop hypothermia 2/2 impaired periph vasoconstriction
• impaired resp response to hypercapnia and hypoxia (Esp concerning in recovery)
• potential for sudden cardiac/pulm arrest possible 2/2 anesthetic induced interference with sinus or respiratory automaticity
• note: one sign is resting tachycardia
