Hyperleukocytosis is the hallmark of malignant pertussis and necessitates urgent and aggressive interventions. Among the therapeutic options, leukoreduction via whole blood exchange (BE) transfusion has been associated with significant procedural risks and potential clinical deterioration.

Among the 27 infants admitted for severe pertussis, 12 exhibited features of malignant pertussis. Of these, seven were treated with hydroxyurea and five with BE. The majority of infants were term and under 3 months old. All patients required ventilatory support, with eight on invasive mechanical ventilation and three receiving extracorporeal membrane oxygenation therapy. Overall mortality was three of 12 (25%).

In the protocolized sedation arm, patients with obesity received significantly higher median opiate doses compared with the nonobesity protocolized sedation group. IWS rates did not differ; however, protocolized sedation obesity patients experienced more instances of inadequate sedation, longer time to extubation readiness, longer duration of mechanical ventilation and PICU stay, and higher 28-day in-hospital mortality than the protocolized sedation nonobesity group.
