Brief Summary

Acute pain episodes associated with sickle cell disease (SCD) are very difficult to manage effectively. Opioid tolerance and side effects have been major roadblocks in our ability to provide these patients with adequate pain relief. This pilot study is designed to examine the safety and feasibility of using ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, in the inpatient seeing with children and adolescents who have sickle cell vasoocclusive pain. Previous research suggests that in subanesthetic doses, ketamine may be able to prevent the development of opiate tolerance and facilitate better pain relief with lower opiate doses, allowing for less respiratory depression, less sedation, easier ambulation, less deconditioning, shorter hospital stays, and better quality of life. The goal of this pilot study is to evaluate the safety and feasibility of using a continuous infusion of ketamine, in conjunction with opiates, in the inpatient setting for sickle cell vasoocclusive pain. It is hypothesized that using a low dose ketamine infusion in conjunction with opiates will be a safe and feasible practice for the treatment of sickle cell pain.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Improvement in Pain Scores of >2 Points on the Pain Scale

    Determine if there is an apparent improvement in pain control with the ketamine infusion based on the investigator's discretion and comparison to past pain scores. Pain was scored on a scale from 0 to 10. Zero equaled no pain and 10 equaled a lot of pain.

    Baseline then daily while inpatient, up to 72 hours

Secondary Outcomes (1)

  • Number of Participants Who Showed a Reduction of Opioid Utilization While on IV Ketamine

    Baseline then daily while inpatient, up to 72 hours

Study Arms (1)

Ketamine

EXPERIMENTAL

This group will receive ketamine

Drug: ketamine

Interventions

Medication administered via IV. This study will utilize 4 doses of ketamine: 0.05 mg/kg/hr, 0.1 mg/kg/hr, 0.15 mg/kg/hr, and 0.2 mg/kg/hr. Dosing Regimen: * Patients begin the ketamine infusion at 0.05 mg/kg/hr. * 4 or more hrs after infusion is started, the dose may be increased to 0.1 mg/kg/hr if: 1. patient's pain has not improved to an acceptable level 2. side effects remain acceptable * 4 hrs or more after the previous increase, the dose may be adjusted to 0.15 mg/kg/hr * 4 hrs or more after the previous increase, the dose may be adjusted to 0.2 mg/kg/hour * Maximum dose of ketamine is limited to 300 mg per 24 hrs Patient may receive ketamine up to 72 hrs after initiation.
