Pharmacokinetics of Bolus Versus Continuous Cefazolin Infusion in Patients Undergoing Major Surgery

• Status: Completed
• Trial end date: 2016-06-01
• Target enrollment: 0
• Participant gender: All

Summary

Abstract The administration of an antibiotic preoperatively is an important intervention that helps to reduce the risk of post-operative health-care associated infections (HCAI). These include urinary tract, surgical site and blood stream infection. Based on the current Surgical Infection Prevention Project, (SCIP) recommendations, the choice of the antibiotic is based on the nature and site of the surgery and the presence of a β-lactam allergy (Table 1).

Currently, the antibiotic treatment for preventing surgical infections is administered as a single bolus an hour before surgery, and every four hours after the initial dose. This presents a concentration profile that has a high concentration after the bolus, but decays as the kidneys remove the antibiotics. In this present study, investigators would like to compare this traditional method of delivery to a constant infusion model that would sustain a constant level of antibiotics that is defined by the difference between the rate of infusion and rate of clearance.
