Clinical Trial Summary

Patients undergoing an elective ventral hernia repair will be randomly assigned to receive either bolus infusion or continuous infusion of the cefazolin as the prophylactic antibiotic. The blood concentrations of unbound cefazolin would be measured in their blood samples and the levels compared within the two groups with respect to their minimal inhibitory concentration (MIC) value.

Description:

Patients who will be undergoing elective ventral hernia repair will be potential candidates for this study. Once identified, the surgical team will approach the participant for consent and inclusion in the study. On the day of surgery, the subjects will be assigned to either the Bolus Group (CB) or Continuous Infusion Group (CI) according to a randomly generated assignment procedure. During the procedure, the dose of prophylactic Cefazolin will be given an hour before surgery and will be administered in accordance to group assignment. Subjects in the CB will receive bolus infusions of Cefazolin every 4 hours till the end of surgery. Subjects in the CI group will receive an initial bolus injection of Cefazolin followed by a continuous infusion till the closure of skin incision. Blood samples will be taken during surgery at t=0, 15, 30 and 60 minutes and every hour following till the end of surgery or 6 hours (whichever comes sooner)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Difference in Area Under Curve (AUC) of Cefazolin plasma concentration and minimum inhibitory concentration (MIC) in both treatment arms	After blood sample collection is completed samples will be analyzed for plasma concentrations of cefazolin. This concentration will be compared with the standard minimum inhibitory concentration of Cefazolin. It is expected that the difference between AUC and MIC in the continuous infusion group will be higher than the bolus infusion group during the first four hours of surgery.	First four hours
Secondary	Difference in AUC of plasma concentration between the two regimens for the entire duration of surgery	After blood sample collection is completed samples will be analyzed for plasma concentrations of cefazolin. This concentration will be compared with the standard minimum inhibitory concentration of Cefazolin. It is expected that the difference between AUC and MIC in the continuous infusion group will be higher than the bolus infusion group for the entire duration of surgery.	Duration of surgery
