Operative Risk Factors of Markmann et al for Poor Outcome After Liver Transplantation

 

Parameters:

(1) bile output during surgery

(2) urine output during surgery

(3) number of platelet concentrates transfused

Parameter	Finding	Points
bile output during surgery	good to fair	0
	poor	1
urine output during surgery	>= 2.0 mL per kg per hour	0
	< 2.0 mL per kg per hour	1
platelet concentrates	< 20 concentrates transfused	0
	>= 20 concentrates transfused	1

 

where:

• A plateletpheresis product may contain the equivalent of 6 to 8 platelet concentrates.

 

number of risk factors for poor outcome =

= SUM(points for the 3 intraoperative parameters)

 

Interpretation:

• minimum number of risk factors: 0

• maximum number of risk factors: 3

• The presence of one or more of the risk factors was associated with a prolonged ICU stay and longer hospitalization.

• The absence of all risk factors was associated with good graft survival.
