Conditions
Brief summary
The purpose of this study is to determine the tissue kinetics of ertapenem in colonic tissue from three hours up to six hours (25% of dosing interval) after administration of ertapenem.
Detailed description
The purpose of this study is to determine the tissue kinetics of ertapenem in colorectal tissue from three hours up to six hours (25% of dosing interval) after administration of ertapenem before an elective surgical intervention (open or laparoscopic surgery) at the colon/rectum. Subjects are patients. Hospitalized patients 18 years or older requiring elective surgical intervention (open or laparoscopic surgery) at the colon will be eligible for this study.
Interventions
powder for infusion, 1 gram I.V., single dose over 30 min.
