Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Ceftazidime-avibactam is used for treatment of invasive Gram-negative bacterial infections among critically ill patients, including those on continuous venovenous hemodiafiltration . However, dosing of ceftazidime-avibactam for these patients remains undefined. The purpose of this study was to evaluate the pharmacokinetics of ceftazidime and avibactam among critically-ill patients, including those receiving CVVHD. This is a registration of Dr. Shields' exempt project under IRB approved research study STUDY19040363

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients who received ceftazidime-avibactam as part of their clinical care were consented. EMR data was collected as well as PK sampling around their dosing to include the following samples immediately pre-dose, then at the following times thereafter: 1, 2, 4, 6, and 8 hours. Blood samples were collected in lithium-heparin tubes from a central venous catheter that is not being used for the continuous venovenous hemodiafiltration. The tubes were centrifuged at 2500 rpm for 10 minutes within 1 hour from collection and the samples will be frozen at 80°C. The total concentrations of ceftazidime and avibactam were determined simultaneously from plasma by using a validated HPLC-tandem MS assay. Noncompartmental pharmacokinetics were calculated using the linear-up and logarithmic-down trapezoidal method, based on the assumption of first-order elimination.
