Sedation Management for Critically Ill Children with Pre-Existing Cognitive Impairment

Objective To compare current analgesia and sedation management practices between critically ill children with pre-existing cognitive impairment and critically ill neurotypicalchildren, including possible indicators of therapeutic efficacy. Study design This study used secondary analysis of prospective data from the RESTORE clinical trial, with 2449 children admitted to the pediatric intensive care unitand receiving mechanical ventilation for acute respiratory failure. Subjects with a baseline Pediatric Cerebral Performance Category ≥3 were defined as subjects with cognitive impairment, and differences between groups were explored using regression methods accounting for pediatric intensive care unitas a cluster variable. Results This study identified 412 subjects (17%) with cognitive impairment. Compared with neurotypicalsubjects, subjects with cognitive impairment were older (median, years, 6.2 vs 1.4; P P  = .009). They received significantly lower cumulative dosesof opioids (median, mg/kg, 14.2 vs 16.2; P P Conclusions Subjects with cognitive impairment in this study received less medication, but it is unclear whether they have authentically lower analgesic and/or sedative requirements or are vulnerable to inadequate assessment of discomfort because of the lack of validated assessment tools. We recommend the development of pain and sedation assessment tools specific to this patient population.
