Condition(s) targeted: Amputation

Intervention: ertapenem (Drug)

Phase: N/A

Status: Withdrawn

Sponsored by: HaEmek Medical Center, Israel

Official(s) and/or principal investigator(s):
Ruth Kitzes, Study Director, Affiliation: Clinical Pharmacology Unit, Carmel Medical Center, Haifa


The aim of the study is to determine the penetration levels of ertapenem into bone tissues in patients with Diabetes Mellitus (D. M) or Peripheral Vascular Diseases (P. V.D) undergoing amputation, and to correlate theme to the concentration of the drug in blood and other soft tissues

Clinical Details

Official title: Penetration of Ertapenem Into Bone in Patients With Diabetes Mellitus or Peripheral Vascular Diseases Who Underwent Bellow Knee Amputation

Study design: Allocation: Non-Randomized, Endpoint Classification: Pharmacokinetics Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: blood,tissue and bone drug levels

Detailed description: Twelve patients with D. M or P. V.D who are undergoing bellow knee amputation with or without gangrene. Within four weeks prior the amputation a vascular profile will be determined by Doppler and skin perfusion will be determined by transcutaneous oxygen pressure measurements (TcPO2) on the dorsal side of the mid foot of the affected limb.

Each patient will receive 1 g of Ertapenem in 100 ml of normal saline by IV infusion - during

30 minutes through IVAC:

- -2 days prior the amputation

- -1 day prior the amputation

- 1 hour before amputation The infusions will be started approximately at the same time

of the 3rd infusion, prior the planned amputation. Blood samples (approximately 6ml each) will be collected before Ertapenem administration, simultaneously with bone and soft tissue samples at the time of amputation and at the end of the surgery


Minimum age: 18 Years. Maximum age: 75 Years. Gender(s): Both.
