Pharmacokinetics of continuous infusion ceftolozane/tazobactam in two patients with extensive total body surface area burns.
Article in Pharmacotherapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionTreatment of infections in patients with burn injuries is challenging due to altered antimicrobial pharmacokinetics. Continuous infusion β-lactam therapy may be a useful antimicrobial stewardship strategy to improve pharmacodynamic target attainment in this population. CASE SUMMARIES: This report highlights the use of continuous infusion ceftolozane/tazobactam (C/T) in two patients with extensive total body surface area (TBSA) burns, suspected augmented renal clearance (ARC), and bloodstream infections caused by Pseudomonas aeruginosa with difficult-to-treat resistance (DTR P. aeruginosa). Both patients received C/T 9 g/day via continuous infusion. Minimum inhibitory concentrations (MIC) of C/T were 8/4 and 4/4 μg/mL in Cases 1 and 2, respectively. DISCUSSION: Despite similar patient characteristics, average free plasma ceftolozane concentrations were 41.6 mg/L in Case 1 and 22.8 mg/L in Case 2. Measured free concentrations exceeded 4 times the MIC for 100% of each 24-h infusion (fT > 4xMIC), and bacteremia was successfully cleared in each case.
conclusionThese cases highlight the variability of drug exposure in patients with extensive TBSA burn injuries and support continuous infusion β-lactam therapy as a proactive strategy to optimize pharmacodynamic target attainment when pharmacokinetics are unpredictable.
