The shortage of a safe and adequate blood supply for open heart surgery has prompted the development and institution of numerous blood conservation and autotransfusion techniques. A survey was conducted of 60 hospitals in the Northeastern United States to determine the frequency of application as well as the resultant effect on banked blood usage.
A total of 37 surveys were returned for a response rate of 62%. This represents an annual caseload of 23449 open heart procedures which is more than 10% of the total number performed annually in the U.S.
The following techniques were used during adult cases to conserve blood:
No blood in prime 95%
Membrane oxygenator 67%
Chest drainage autotransfusion 40%
Autotransfusion of suction blood 40%
Pre-bypass volume removal 18%
Hemoconcentrator 8%
Post bypass techniques for recovery of residual pump volume were also surveyed. The following techniques were employed:
Centrifugation 54%
Blood bag collection 31%
Discarded 11%
Hemoconcentration 4%
Kendall's Tau-b correlation coefficients showed a significant association between autotransfusion of suctioned blood (p<.05) and decreasing reported blood use, as well as priming volume and blood use (p<.05), although correlations were of small magnitude. When usage was compared across units of packed red cells, for several blood conservation techniques greater usage was reported in the groups that used the smallest amount of blood.
