Early postoperative outcomes of coronary artery bypass grafting patients on-pump versus off-pump

Abstract EN

Coronary artery bypass grafting (CABG) is defined as “open-heart surgery in which a section of a blood vessel is grafted from the aorta to the coronary artery to bypass the blocked section of the coronary artery.

Cardiac surgery became more feasible in the late 1930s with the development of the heart-lung machine by Dr.

John Gibbon which enabled cardiopulmonary bypass (CPB).

This study aimed at comparing early postoperative outcomes between patients undergone CABG on-pump versus off-pump.

The study was done on 40 patients, 20 of them was done by on-pump technique and the other 20 was done by off-pump technique.

All the patients were transferred to intensive care unit and were observed for the following criteria: Early postoperative bleeding, Cardiac support (Medical or Mechanical), Different types of Arrythmias, Renal function and Hospital stay.

Early postoperative bleeding: appears to be more with On-pump technique in the first 3 post operative days.

Cardiac support (Medical or Mechanical) : No significant difference with both techniques.

Different types of Arrythmias : No significant difference with both techniques.

Renal function: No significant difference with both techniques except of only one patient needed renal dialysis was done by on-pump technique.

Hospital stay : No significant difference with both techniques with mean days of hospital stay for all patients of 8 days.

In conclusion, our trial did not show any overall advantage to the use of the off-pump as compared with the on-pump cardiac surgical approach for coronary bypass grafting.
