Management of acute pain in adults with sickle cell disease: the experience of the Clinical Hematology Department of the University of Dakar.

BACKGROUND/AIM: The evolution of sickle cell disease (SCD) is marked by the occurrence of painful episodes linked to the obstruction of microvessels by sickle cells, known as vaso-occlusive crisis (VOC). The aim of this work was to report the practical aspects of the management of acute pain in adults with SCD. Recommendations based on these practices are also provided.

MATERIALS AND METHODS

This prospective, cross-sectional, descriptive, and analytical study was conducted over a four-month period of all sickle cell patients admitted to emergency departments for VOC. The parameters studied were sociodemographic, clinicobiological, therapeutic, and evolutionary.

RESULTS

There were 118 cases of VOC identified, representing a prevalence of 78.14% of sickle cell emergencies. The mean age of the patients was 28.41 years. The SS sickle cell phenotype accounted for 86.61% of the cases. Osteoarticular pain was the reason for admission for 88.39% of the patients; it was located in the lower limbs in 39.08% and in the spine in 27.1%. Pain intensity was moderate in 6.25% of the patients, intense in 31.25%, and unbearable in 55.55%. Multimodal analgesia was the most commonly used treatment method, combining those of levels one and two (74.31%) and levels one and three (8.25%). The mean dose of morphine administered was 17.14 mg when morphine alone was prescribed for titration, 13.57 mg when paracetamol and morphine were combined, and 15.83 mg when nefopam and morphine were combined. Clinical outcome was favorable in 68.87% of the cases.

CONCLUSION

Wide variability was observed in the modalities of analgesic treatment of sickle cell VOC. These variations reflect different views on the appropriateness of opioids. This study highlights the efficacy of multimodal analgesia in the management of acute pain in patients with SCD, particularly in regard to morphine sparing. Context-specific recommendations will be needed to harmonize practices.
