Failed Conscious Sedation During Procedure
Conditions
Keywords
Pediatric intensive care unit, Sedation, Dexmedetomidine, mechanical ventilation
Brief summary
To observe the efficacy and safety of dexmedetomidine sedation on the patients admitted to the pediatric intensive care unit after surgery.
Interventions
midazolam 3~5μg/kg•min for maintenance of sedation.
Dexmedetomidine 0.5μg/kg intravenous bump for 15 min,then 0.2~1.4μg/(kg.h) for maintenance of sedation;
Fentanyl 0.5~4 μg/(kg.h) for maintenance of analgesia
Ramsay score for sedation assessment, Facial expression, leg movement, activity, cry, and consolability score (FLACC) for analgesia assessment.
