Nitrous Oxide for Analgesia in Sickle Cell Vaso-occlusive Crisis

Columbia University·interventional·Posted Jul 3, 2013·Updated Jan 28, 2026

In Brief

A Phase 2 clinical trial evaluating Nitrous oxide 50% for Sickle Cell Disease and Vaso-occlusive Crisis. Completed, enrolled 5 participants across 1 site.

Detailed Summary

Patients who have sickle cell VOC are usually treated with opioids, such as morphine. However, this current way of treating them has not improved the health, medical outcomes, or rates of hospitalizations. In addition, since VOC can happen very frequently over a long period of time, giving opioids over and over again can cause both short-term and long-term problems. Nitrous oxide (N2O) is a way of treating pain that may provide a better alternative to repeatedly giving opioids over long periods of time. N2O has been shown to provide up to 3 hours of pain relief in inpatient patients with VOC whose pain did not improve with morphine infusions, and is used extensively in France, where almost half of 85 pediatric emergency departments use nitrous oxide to treat children with VOC whose pain did not get better with standard treatment with morphine. However, pain relief which N2O provides in the acute setting has not been well described. Therefore, the purpose of our study is to describe how well N2O can relieve the pain in patients with SCD who present to the emergency department and are experiencing a VOC.
