Arms Assigned Interventions
Experimental: Ertapenem

Free tissue kinetics of ertapenem in fatty tissue and intraperitoneal fluid in mg/L

Free and bound plasma concentration of ertapenem or meropenem in mg/L

Procedure: microdialysis catheter
Placing of microdialysis catheter in fatty tissue and in the peritoneal cavity
Experimental: Meropenem
Free tissue kinetics of meropenem in fatty tissue and intraperitoneal fluid in mg/L up to 24 hours after administration. Free and bound plasma concentration of meropenem in mg/L.
Procedure: microdialysis catheter
Placing of microdialysis catheter in fatty tissue and in the peritoneal cavity

Detailed Description:
The purpose of this study is to determine the free tissue kinetics of ertapenem and meropenem in fatty tissue and intraperitoneal fluid up to 24 hours after administration of the IMP.
