Impact of Ketamine in the Management of Painful Sickle Cell Disease Vaso-Occlusive Crisis

Abstract

The aim of the study is to determine if ketamine infusions in combination with opioid therapy for the management of sickle cell disease (SCD) presenting with vaso-occlusive crisis (VOC) resulted in a length-of-stay difference compared to when ketamine was not utilized. This single center, retrospective, observational study performed at an academic medical center evaluated 12 adult patients with SCD-VOC who received a ketamine infusion with standard opioid therapy between 2014 and 2017. Patients were excluded if the primary diagnosis was not VOC or they did not survive to discharge. Additionally, safety and oral morphine equivalents at various time points were compared. Patients were used as their own control using the previous SCD-VOC hospitalization to evaluate the relative impact of ketamine. Wilcoxon signed-rank and rank sum were used in statistical analysis. When comparing opioid doses during the ketamine infusion, a P-value
