Efficacy and Safety of Continuous Versus Intermittent Linezolid Infusion in Critically Ill Patients With Septic Shock

Ain Shams University140 enrolled

Overview

The aim of study is this to evaluate the efficacy and safety of continuous linezolid infusion versus the standard regimen in treating critically ill patients with septic shock in the ICU

it is Prospective randomized controlled study on One hundred forty patients to evaluate the efficacy and safety of continuous linezolid infusion versus the standard regimen in treating critically ill patients with septic shock in the ICU, Initially, each patient will be evaluated for septic shock based on the clinical criteria. Baseline microbiologic specimens will be obtained for all recruited patients through the day of diagnosis including blood C\&S. Then, empirical treatment with antibiotics according to expected source of sepsis. Patients with Gram-positive cultures sensitive to Linezolid will be randomly allocated to receive Linezolid in the continuous infusion group (Group A) or conventional intermittent infusion group (Group B) in a 1:1 ratio. Group A: seventy Patients in the continuous infusion group will receive an intravenous loading dose of 600 mg for 60 min, followed by a continuous infusion of 1200 mg/day (50 mg/h). Group B: seventy patients in the intermittent infusion group will administrate 600 mg of linezolid IV every 12 h for 60 min. The treatment period will be 8-10 days in both groups but might decrease or increase based on the patients' clinical response. At the beginning of the study, simple randomization will be used to assign patients using the random numbers set offered by the ICU coordinator. Each patient will be assigned a randomized code consisting of two letters that indicate the intensive care unit and two digits indicating the randomization sequence. The end point of the study is occurrence of thrombocytopenia (decrease in platelet count ≥ 50% from baseline or a decrease in platelet count ≤ 100 × 103/mm3).
