We hypothesized that in critically-ill patients with SCD receiving cefotaxime during acute chest syndrome, the continuous infusion may outperform the intermittent administration in achieving pharmacokinetic/pharmacodynamic targets. DesignProspective before-after study. SettingsIntensive-care unit of a French teaching hospital and sickle cell disease referral center. PatientsSixty consecutive episodes of severe acute chest syndrome in 58 adult patients with sickle cell disease. InterventionsPatients were treated with intermittent administration during the first period (April 2016 –April 2018) and with continuous infusion during the second period (May 2018 –August 2019). Measurements and main resultsWe included 60 episodes of acute chest syndrome in 58 patients (29 [25 –34] years, 37/58 (64%) males). Daily dose of cefotaxime was similar between groups (59 [48–88]vs. 61 [57 –64] mg/kg/day, p = 0.84). Most patients (>75%) presented a glomerular hyperfiltration with no difference between groups (p = 0.25). More patients had a cefotaxime trough level ≥2 mg/L with continuous infusion than intermittent administration: 28 (93%)vs. 5 (16%), p
