Thromboelastogram (TEG)

Question 1

R time =

Answer 1

• Time to begin forming the clot formation
• 6-8 minutes
• Determined by coagulation factors
  
  • Treat with FFP

Question 2

K time

Answer 2

• Time until the clot has achieved fixed strength.
• 3-7 minutes
• Fibrinogen
• Give Cryo

Question 3

Alpha angle=

Answer 3

• Speed of fibrin accumulation
• 50- 60 degrees
• Fibrinogen problem area
• Give cryo

Question 4

Maximum amplitude (MA)

Answer 4

• Measurement of clot strength
• Highest vertical amplitude
• 50-60mm
• Platelet problem area
• Give platelets +/- DDAVP

Question 5

Amplitude at minutes after maximum amplitude (A60) =

Answer 5

• Height of vertical amplitude 60 minutes after the maximum amplitude.
• MA -5
• Excess fibrinolysis
• Give TXA
