A Novel Mechanistic Model for Future Research in the Elements of the ERAS Program in Patients With Sickle Cell Disease.

Enhanced recovery after surgery (ERAS) is a patient-centered, evidence-based, multidisciplinary team-developed approach to a surgical stress response that is implemented to optimize physiological function and facilitate recovery for the best possible outcomes from surgery. Although there are currently well-known published guidelines for the perioperative management of patients with sickle cell disease, there are currently no specific and evidencebased ERAS protocols that address the needs of these patients. A novel mechanistic model has recently been found that could change ERAS protocols for patients with sickle cell disease with regard to a current preoperative carbohydrate loading drink recommendation, nutrition and intravenous fluid management. ERAS has great benefits for most patient populations, but emerging research suggests that patients with sickle cell disease may process and respond differently to varying concentrations of serum glucose and serum cations (hyperglycemia and hypertonic states). This adverse response involves actin, a cytoskeletal protein, in the red blood cell and how increased hemoglobin glycosylation may lead to a malfunction in this protein and a transition to vaso-occlusive crises in patients with sickle cell disease. Further research is warranted with this new mechanistic model to develop more meticulous and customized perioperative management plans to address risk mitigation in patients with sickle cell disease.
