Continuous v Bolus Infusion of Cefazolin During Whipple Procedure

2016-01-28 16:53:24 | BioPortfolio


Patients undergoing an elective whipple procedure 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.


Patients who will be undergoing elective Whipple procedures 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 Whipple 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.

Medical and Biotech [MESH] Definitions

Use of any infusion therapy on an ambulatory, outpatient, or other non-institutionalized basis.

An intravenous anesthetic agent which has the advantage of a very rapid onset after infusion or bolus injection plus a very short recovery period of a couple of minutes. (From Smith and Reynard, Textbook of Pharmacology, 1992, 1st ed, p206). Propofol has been used as ANTICONVULSANTS and ANTIEMETICS.

A semisynthetic cephalosporin analog with broad-spectrum antibiotic action due to inhibition of bacterial cell wall synthesis. It attains high serum levels and is excreted quickly via the urine.

Fluid propulsion systems driven mechanically, electrically, or osmotically that are used to inject (or infuse) over time agents into a patient or experimental animal; used routinely in hospitals to maintain a patent intravenous line, to administer antineoplastic agents and other drugs in thromboembolism, heart disease, diabetes mellitus (INSULIN INFUSION SYSTEMS is also available), and other disorders.

Adverse reactions that occur initially at the site of injection or infusion. Milder type is confined to a local allergic flare reaction. A more severe reaction is caused by extravasation of VESICANTS from the blood vessel at the site of injection and can cause damage to the surrounding tissue. In tumor flare reaction symptoms involve well beyond the injection site such as an increase in the tumor size and tumor markers levels, bone pain, and HYPERCALCEMIA.
