    Abstract:
    The aim of this study was to describe the characteristics of vaso-occlusive crises (VOC) in children with sickle cell disease and to identify factors associated with greater severity. We performed a prospective observational study from August 2012 to January 2014. The study population comprised patients with sickle cell disease who consulted at the emergency department (ED) for VOC. We recorded demographic variables, history of complications related to the disease, and data on usual treatment. We also assessed pain, analgesia at home, need for admission, length of stay, and analgesia during admission. Analytical parameters were collected. A total of 29 patients with VOC were included. The patient's usual treatment was hydroxyurea (HU) in 69.0%, and 7.0% required chronic transfusions. In the ED, 90.0% had moderate or severe pain, even though 86.0% had received analgesia at home (41.4% minor opioids). Overall, 27 of the 29 patients were admitted, and 56.0% needed major opioids. Higher lactate dehydrogenase (LDH) levels were related to the use of major opioids during admission (p = 0.038). A significant difference was recorded between the median number of days of admission for patients receiving non-steroidal anti-inflammatory drugs and for those requiring intravenous opioids (p = 0.005). Most patients with VOC were admitted to hospital. Lactate dehydrogenase level in the ED was a predictor of severity and was associated with the need for major opioids during admission and more days of admission.
