The optimal management of recurrent painful episodes in individuals living with sickle cell disease (SCD) remains unclear. Currently, the primary treatment for these episodes remains supportive, using fluids and intravenous opioid and anti-inflammatory medications. Few reports have described the use of adjunct subanesthetic doses of ketamine to opioids for treatment of refractory pain in SCD. This article reports a retrospective case series of five patients admitted to the intensive care unit (ICU) with prolonged vaso-occlusive episodes (VOEs). Patients were treated with a continuous-infusion of low-dose ketamine (up to 5 µg/kg/min) after insufficient pain control with opioid analgesic therapy. Outcomes studied included impact on opioid analgesic use, a description of ketamine dosing strategy, and an analysis of adverse events due to opioid or ketamine analgesia. Descriptive statistics are provided. During ketamine infusion, patients experienced a lower reported pain score (mean numeric rating scale [NRS] score 7.2 vs. 6.4), reduced opioid-induced adverse effects, and decreased opioid dosing requirements (median reduction of 90 mg morphine equivalents per patient). The average duration of severe pain during admission prior to ketamine therapy was 8 days. Only one of five patients reported an adverse effect (vivid dreams) secondary to ketamine infusion. The Richmond Agitation Sedation Scale (RASS) was assessed throughout therapy, with only one patient experiencing light drowsiness. Low-dose ketamine infusion may be considered as an adjunct analgesic agent in patients with vaso-occlusive episodes who report continued severe pain despite high-dose opioid therapy, particularly those experiencing opioid-induced adverse effects.

Introduction Acute liver failure (ALF) is an ideal condition for use of a checklist. Our aims were to develop a checklist for the management of ALF in the intensive care unit (ICU) and assess the usability of the checklist among multiple providers. Methods The initial checklist was developed from published guidelines and expert opinion. The checklist underwent pilot testing at 11 academic liver transplant centers in the US and Canada. An anonymous, written survey was used to assess the usability and quality of the checklist. Written comments were used to improve the checklist following the pilot testing period. Results We received 81 surveys involving the management of 116 patients during the pilot testing period. The overall quality of the checklist was judged to be above average to excellent by 94% of users. On a 5-point Likert scale, the majority of survey respondents agreed or agreed strongly with the following checklist characteristics: the checklist was easy to read (99% agreed/agreed strongly), easy to use (97%), items are categorized logically (98%), time to complete the checklist did not interfere with delivery of appropriate and safe patient care (94%) and was not excessively burdensome (92%), the checklist allowed the user the freedom to use his or her clinical judgment (80%), it is a useful tool in the management of acute liver failure (98%). Web-based and mobile apps were developed for use of the checklist at the point of care. Conclusion The checklist for the management of ALF in the ICU was shown in this pilot study to be easy to use, helpful and accepted by a wide variety of practitioners at multiple sites in the US and Canada.
