NCT06315920 | NOT YET RECRUITING | Sickle-Cell Disease with Crisis

Detailed Description:

Introduction: Sickle Cell Disease (SCD) is a prevalent hematological disorder in Oman. Patients frequently present to Emergency Departments (ED) with painful crises, often requiring high doses of opioids like Morphine. However, the complications associated with opioid use, including dependency, necessitate exploring alternative analgesic options. This research proposes a comparative study of Parecoxib, a non-steroidal anti-inflammatory drug (NSAID), and Morphine in managing pain for SCD patients in the ED. Background: Recent studies have highlighted Parecoxib's potential in various clinical settings. In trauma patients, Parecoxib demonstrated comparable analgesic efficacy to Morphine, suggesting its broader applicability in the ED. Parecoxib has shown benefits in post-operative pain management, reducing opioid requirements and associated adverse events. Notably, in post knee replacement surgeries, Parecoxib effectively managed pain and facilitated functional recovery. It also contributed to decreased postoperative delirium in elderly patients undergoing hip or knee replacement surgery without increasing adverse events. Research Objectives: The primary objective of this study is to evaluate the analgesic efficacy of Parecoxib versus Morphine in SCD patients experiencing vaso-occlusive crises. Secondary objectives include assessing the potential reduction in opioid dependence, length of hospital stay, recurrence of ED visits, and monitoring any Parecoxib-related side effects in SCD patients. Methodology: * Study Design: A double-blinded, randomized controlled trial. * Study Setting: AFH Emergency Department, a tertiary care institution. * Target Population: Adult SCD patients (\>18 years) presenting with moderate to severe vaso-occlusive crises. * Exclusion Criteria: Include non-VOC pain, weight \< 50 kg, frequent ED visits, recent opioid/NSAID use, contraindications to NSAIDs, lactating mothers, and recent visits to other health institutions. * Sample Size: The sample size of 226 patients, split into two groups of 113 each, was determined for a two-sided hypothesis test with a 5% significance level and 90% power. This design ensures a high probability of detecting a significant difference in the analgesic efficacy between Parecoxib and Morphine for SCD patients. The calculated size is based on expected effect sizes from previous research, with additional allowance for potential dropouts, ensuring the study's statistical validity and comprehensiveness. * Intervention: Computer-randomized administration of Morphine or Parecoxib. Continuous monitoring of vital signs and pain assessment at set intervals post-medication administration. Senior emergency physicians and residents will conduct assessments. * Data Collection and Analysis: The study will be double-blinded, with only the preparing nurse aware of the medication used. Data will be recorded using Epi-Data and analyzed using SPSS version 25. Expected Outcomes: The study aims to enhance pain management protocols for SCD patients in the ED. By introducing Parecoxib as an alternative to opioids, we anticipate reduced opioid use, shortened hospital stays, fewer ED visits, and overall cost-effectiveness in managing SCD pain crises. The findings will be disseminated through local and international conferences and journals.
