Outcomes of interest were sedation depth, ED length of stay (EDLOS), adverse events, procedural success and clinician\/carer satisfaction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 114 patients were recruited. Median age was 3\u2009years (IQR 2\u20135), 55.3% were male and 31.6% were Aboriginal and\/or Torres Strait Islander children. Median IN DEX dose was 3.11\u2009mcg\/kg (IQR 2.81\u20133.93). Common indications included peripheral intravenous cannulation (35.1%), laceration repair (21.1%), burns care (13.2%), foreign body removal (11.4%) and medical imaging (8.8%). Median EDLOS was 395\u2009min (IQR 255\u2013579). Sedation depth was moderate (mean University Michigan Sedation Scale score 2.1 (SD 0.9), a 0\u20134 scale on which higher scores indicate deeper sedation; documented for 90 of 114 sedations). IN DEX was successful as a sole sedative agent in 78.1% (95% CI 69.6%\u201384.7%) patients, ranging from 90.0% (9\/10) for medical imaging to 53.8% (7\/13) for foreign body removal. Adverse events occurred in 13.2% of patients (95% CI 8.1%\u201320.6%), predominantly mild bradycardia. Younger age was associated with higher success rates (aOR 0.86 per year, 95% CI 0.74\u20130.998). No dose\u2013response relationship was identified. Clinicians (mean 4.3\/5) and parents (mean 4.5\/5) reported high satisfaction, although satisfaction was documented for fewer than half of sedations and significantly more often when sedation succeeded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In our single\u2010centre study IN DEX is a well\u2010tolerated, moderately effective and safe agent for ED paediatric procedural sedation with higher success rates in younger patients.
