Brief Summary

Acute vaso-occlusive episodes (VOEs) in sickle cell disease (SCD) are primarily managed with opioids. Tolerance and hyperalgesia to opioids develops due to N-methyl-D-aspartate (NMDA)-receptor mediated activation of the nociceptive system, and as a receptor antagonist, ketamine mitigates this. Intravenous (IV) ketamine has demonstrated efficacy in reducing post-operative, chronic, and cancer-related pain in pediatrics, as well as in reducing time to pain control in the emergency department (ED) in adults. Limited studies suggest efficacy in adult opioid-refractory SCD patients. This study is investigating the safety and tolerability of adjuvant low-dose IV ketamine bolus for pediatric SCD VOE in the ED, as well as its efficacy in improving pain control and reducing hospitalization.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Treatment-Emergent Adverse Events [Safety and Tolerability]

    The number of serious and minor adverse events was measured via patient-completed survey as well as by nurse and medical providers on presentation to the emergency department (ED). Serious adverse events are defined as cardiorespiratory events requiring intervention. Minor adverse events are defined as nausea/vomiting, emergence reaction (dysphoria; hallucinations; frightening dreams), and a sense of de-realization or "dreamy" sensation. Both study providers and patients themselves, via a survey that the parent and/or patient (based on age) fills out post receipt of ketamine, reported serious and minor adverse events.

    18 months

Secondary Outcomes (7)

  • Effect of Low-dose Ketamine (LDK) on Opioid Usage in the ED

    Up to one year prior and after LDK administration on day 1 of the study in the ED

  • Effect of Low-dose Ketamine on Pain Scores on Presentation to the ED

    Up to one year prior and on presentation to the ED after LDK administration

  • Effect of Low-dose Ketamine on Discharge Rates From the ED

    Up to one year prior to receipt of ketamine for the historical control arm/group and up to 18 months for the intervention arm/group

  • Subjective Effect of Low Dose Ketamine on Pain Relief Assessed Via a Patient Survey

    after LDK administration on day 1 of the study in the ED

  • Effect of Low-dose Ketamine on Patient Pain Scores on Discharge From the ED/Admission to the Hospital

    At time of discharge from the ED/admission to the hospital (up to one year prior and after LDK administration)

  • +2 more secondary outcomes

Study Arms (2)

Intervention

ACTIVE COMPARATOR

Prior to the second dose of IV opiates, the experiment was to give patients a single IV bolus of ketamine at the dose of 0.2 mg/kg. Pain scores were collected using the FACES scale currently in place. In consenting patients, chart review was performed with the following data collected: mg/kg/hour of morphine equivalents, pain scores on admission, during the encounter, and at discharge, the time to 50% pain reduction, and whether or not the patient was discharged. In addition, a survey, which is attached, was given to patients/families at the time of drug administration to determine if they experienced a subjective improvement in their pain and if they suffered any undue side effects due to drug administration.

Drug: Ketamine

Historical Control

NO INTERVENTION

Patient data from at least one but up three patient encounters within the prior year were compared to their visit in which they were given adjuvant ketamine, using the outcome measures in the "Intervention" arm. Since this a historical control study, patients acted as their own controls in the above manner. Patients were allowed to re-enroll 4 weeks after presentation, which is typically considered a separate vaso-occlusive episode in the literature.

Interventions

The intervention is IV low-dose bolus ketamine as an adjuvant to standard therapy (IV opiates and NSAIDs).

Eligibility Criteria

Age10 Years - 25 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • All English-speaking, sickle cell patients who receive their care at UCSFBCHO in the Department of Hematology who are 8-to-25-years-old presenting to the emergency department for VOC were asked to enroll.

You may not qualify if:

  • Prior adverse reaction to ketamine
  • Patients were asked during the consent process if they have ever received ketamine, and if so, if they had any serious adverse reaction, such as difficulty breathing, dysphoria, hallucinations, or allergic reaction. If they have, ketamine was not given to these patients.
  • Patients who have received ketamine and experienced nausea or vomiting will be asked if they wish to receive the medication. If they do not, they did not receive ketamine.

Limitations and Caveats

Given the study design (non-blinded, non-randomized), the effect of LDK on opioid usage and other secondary outcomes cannot be definitively associated with LDK itself given the possibility of a placebo effect.
