Anemia is common in the perioperative period and is associated with poor patient outcomes. Remarkably, anemia is frequently ignored until hemoglobin levels drop low enough to warrant a red blood cell transfusion. This simplified transfusion-based approach has unfortunately shifted clinical focus away from strategies to adequately prevent, diagnose, and treat anemia through direct management of the underlying cause(s). While recommendations have been published for the treatment of anemia before elective surgery, information regarding the design and implementation of evidence-based anemia management strategies is sparse. Moreover, anemia is not solely a concern of the preoperative encounter. Rather, anemia must be actively addressed throughout the perioperative spectrum of patient care. This article provides practical information regarding the implementation of anemia management strategies in surgical patients throughout the perioperative period. This includes evidence-based recommendations for the prevention, diagnosis, and treatment of anemia, including the utility of iron supplementation and erythropoiesis-stimulating agents (ESAs).
Background Enhanced recovery after surgery (ERAS) attempts to decrease the surgical stress response to minimize postoperative complications and improve functional rehabilitation after major surgery, but it have not been widely utilized in spinal surgery. This study is to evaluate the implementation of an ERAS pathway for patients undergoing oblique lumbar interbody fusion (OLIF) surgery. Methods This was a retrospective cohort study of patient who underwent OLIF in 2018 prior to ERAS ("pre-ERAS" ,n=23) and in 2019 after ERAS was instituted ("ERAS", n=24). Major outcomes were collected included demographics, length of hospital stay, nancial cost, postoperative complications, off-bed time and perioperative factors. Visual Analogue Scale (VAS) was used to evaluate the pain. The ERAS pathway and compliance with pathway elements were also recorded. Results After ERAS implementation, we found no signi cant differences in the baseline characteristics between the two groups. In our study, the mean stay in the hospital was signi cantly lower (p= 0.033) in the ERAS group (15.3±3.9 days) compared to the standard pathway group (13.0±3.1 days). In comparison to the standard group, we also found a variation between the nancial costs of surgery and hospitalization [(16446.5±4353.3)vs(14237.7±2784.9) USD, P < 0.05]. The ERAS group manifested a lower blood loss compared with the pre-ERAS group with statistical signi cance [(68.3±57.1)vs(119.3±104.8) ml, P < 0.05]. There was no signi cant difference in operative time, complications, and 30-d readmission rates (P > 0.05). Pain scores between the two groups showed a signi cant difference during the 3th hour and 6th hour (P < 0.05). Conclusion Institution of an ERAS protocol appears to accelerate functional recovery and reduce length of stay, nancial costs and decreased pain.
Preoperative carbohydrate loading is a contemporary element of the enhanced recovery after surgery (ERAS) paradigm. In addition to intraoperative surgical and anesthetic modifications and postoperative care practices, preoperative optimization is essential to good postsurgical outcomes. What was long held as dogma, a period of prolonged fasting prior to the administration of anesthesia, was later re‐examined and challenged. Along with the proposed physiologic effects of decreasing the surgical stress response and insulin resistance, preoperative carbohydrate loading was also demonstrated to improve patient satisfaction and well‐being, without an increase in perioperative complications. The benefits are most strongly observed in abdominal and cardiac surgery patients, but there has also been data which support its use in other specialties and surgeries. Barriers to the adoption of perioperative carbohydrate loading are few, but importantly include overcoming the inertia to modify older and more restrictive fasting guidelines and achieving the multidisciplinary consensus necessary to implement such changes. Despite these challenges, and with an existing body of evidence supporting its benefits, preoperative carbohydrate loading presents a significant contribution to the ERAS programs.
