Purpose:
To verify the direct average cost of the material used in the Coronary Artery Bypass Graft (CABG) Surgery and to compare the average cost according to the number of bypasses perfomed (arterial and veins grafts).
Methods:
This is a descriptive study conducted in a Cardiac Surgery Center in S o Paulo city. The sample includes 104 procedures for CABG surgery with extracorporeal circulation. The information was collected by a standard printed torn containing the material.
Results:
The analyses of the information showed that the direct mean cost of the material used in the surgery was R$2.718,78.
Conclusions:
A variation of material costs was observed proportional to the increase in number of bypasses performance, showing a statistical significant difference among surgerical interventions with 1, 2 and 3 cal bypasses which was not observed in surgeries with 3, 4 and 5 bypases. The direct mean cost was: CABG with 1 bypass (R$2.207,71), 2 (R$2.554,61), 3 (R$2.768,94), 4 (R$2.848,65) and 5 (R$2.884,13). The items of the perfusion material (R$1.051,24), surgical threads (R$829,98) and consumption material (R$442,40), represented those with a higher mean cost.
