Red Blood Cell Conservation and Use in the Cardiovascular Operating Rooms at Ben Taub General Hospital.

OBJECTIVES: A conservative hemoglobin transfusion threshold is noninferior to a liberal threshold in cardiac surgery. However, red blood cell (RBC) transfusion remains common during cardiac surgery. The authors' single-center, retrospective study aimed to decrease RBC transfusions for hemoglobin >7.5 g/dL in nonemergent cardiovascular surgeries utilizing cardiopulmonary bypass (CPB), by educating the anesthesiology and surgical staff on the benefits of a conservative threshold for transfusions, and incorporating the discussion and routine use of blood conservation methods for all nonemergent cardiac surgeries. DESIGN: This was a single-center, retrospective study that included all nonemergent coronary artery bypass grafting and single-valve cases utilizing CPB from January 2018 to December 2021 before and after the intervention in July 2019. SETTING: The data involved a single community hospital. PARTICIPANTS: A total of 417 patients were included in the study. INTERVENTIONS: The authors adopted a conservative threshold for blood transfusion and implemented a collaborative multidisciplinary approach to blood conservation. MEASUREMENTS AND MAIN RESULTS: Baseline patient characteristics were summarized, and the incidence of RBC transfusion before and after the intervention on July 26, 2019, were compared by Wilcoxon rank sum and chi-square tests. Multivariate logistic regression was used. The intervention was significantly associated with reduced RBC transfusion rate after adjusting for confounding variables (p < 0.05). The odds of receiving an RBC transfusion among patients after the intervention was 0.615 times the odds among patients before intervention (95% CI: 0.3913-0.9663). CONCLUSIONS: The authors' goal was to improve patient outcomes and the quality of perioperative care during cardiac surgery. By implementing a protocol and educating anesthesiologists, surgeons, and perfusionists, they successfully decreased the incidence of RBC transfusion above a hemoglobin of 7.5 g/dL.

Pulmonary prehabilitation and smoking cessation.

PURPOSE OF REVIEW: This review aims to summarize the current literature on pulmonary prehabilitation programs, their effects on postoperative pulmonary complications, and the financial implications of implementing these programs. Additionally, this review has discussed the current trends in pulmonary prehabilitation programs, techniques for improving rates of perioperative smoking cessation, and the optimal timing of these interventions. RECENT FINDINGS: Prehabilitation is a series of personalized multimodal interventions tailored to individual needs, including lifestyle and behavioral measures. Pulmonary prehabilitation has shown to reduce postoperative pulmonary complications (PPCs). SUMMARY: The implications of clinical practice and research findings regarding PPCs are an increased burden of postoperative complications and financial cost to both patients and hospital systems. There is convincing evidence that pulmonary prehabilitation based on endurance training should be started 8-12 weeks prior to major surgery; however, similar rates of improved postoperative outcomes are observed with high-intensity interval training (HIIT) for 1-2 weeks. This shorter interval of prehabilitation may be more appropriate for patients awaiting thoracic surgery, especially for cancer resection. Additionally, costs associated with creating and maintaining a prehabilitation program are mitigated by shortened lengths of stay and reduced PPCs.
