Abstract
Introduction: Mechanical ventilation (MV) is a common and often live-saving intervention on the Intensive Care Unit (ICU). The optimisation of sedation to mechanical ventilation is fundamental, and inappropriate sedation has been associated with worse outcomes. This scoping review has been designed to answer the question 'What is known about the use of ketamine as a continuous infusion to provide sedation in mechanically ventilated adults in the intensive care unit, and what are the gaps in the evidence?'
Methods: The protocol was designed using the PRISMA-ScR checklist and the JBI manual for evidence synthesis. Data were extracted and reviewed by a minimum of two reviewers.
Results: Searches of electronic databases (PubMed, OVID, Scopus, Web of Science) produced 726 results; 45 citations were identified for further eligibility assessment, an additional five studies were identified through keyword searches, and 12 through searching reference lists. Of these 62 studies, 27 studies were included in the final review: 6 case reports/case series, 11 retrospective cohort/observational studies, 1 prospective cohort study, 9 prospective randomised studies.
Conclusion: We found a lack of high-quality well-designed studies investigating the use of continuous ketamine sedation on ICU. The available data suggests this intervention is safe and well tolerated, however this is of very low certainty given the poor quality of evidence.
