Opioid Use in Patients With Sickle Cell Disease During a Vaso-Occlusive Crisis: A Systematic Review.

Sickle cell disease (SCD) affects the red blood cells, which become sickle-shaped, leading to their adhesion to vascular walls, impeding blood flow and causing the unpredictable, abrupt onset of intense pain episodes in the form of vaso-occlusive crises (VOC) as well as affecting multiple organ systems. The primary aim of this review is to assess the effectiveness of opioid analgesic intervention for pain management in sickle cell disease during an acute painful crisis. A literature search was done electronically on PubMed Central (PMC), PubMed, and Google Scholar databases. The reports included in the study were from 2010 to 2021, and the bibliographies of retrieved studies are included in the references. This systematic review was undertaken as per the Preferred Reporting Items for Systematic Review and Meta-Analysis. This study included reports discussing opioid analgesics in SCD patients during VOC in different settings. After extensive research, there were no clear current opioid treatment patterns described, and our conclusion suggested conducting more evidence-based research to improve the quality of VOC management and outcome.
