Continuous Infusion Versus Intermittent IV Bolus of Cefazolin: Prevention of Surgical Site Infection During CABG Surgeries in Egyptian Patients.

A randomozed control trial on adults who underwent CABG surgery. To evaluate the effectiveness of intraoperative continuous infusion (CI) of cefazolin compared with intermittent (INT) cefazolin administration in preventing SSIs in a CABG (coronary artery bypass grafting) population. Eligible patients will be randomized using block randomization into 2 groups: intervention group and control group. The intervention group will use continuous infusion of cefazolin (CI), while the control group will follow the traditional presurgical prophylaxis protocol of intermittent cefazolin doses (INT).

Exclusion Criteria: * Patients who require reoperation within 30 days. * Immunosuppressant patients. * Patients who are not adherent to the protocol time or dosing, either preoperatively, during, or postoperatively. * Pregnancy or breastfeeding. * Patients who refused to sign the informed consent.
