Association of antepartum anemia and red blood cell mass with racial and ethnic disparities in transfusion rates after cesarean delivery: A retrospective cohort study.

Background: Antepartum anemia among patients undergoing cesarean deliveries has increased over the past decades in the United States. We hypothesized that red blood cell (RBC) mass, reflecting both prepartum anemia and body mass index (BMI), predicts transfusion risk after cesarean delivery beyond racial/ethnic categories.

Study Design And Methods: A retrospective analysis of cesarean deliveries from 2019 to 2021 was performed using the National Surgical Quality Improvement Program database.

Temporal changes and predictors of perioperative blood transfusion in elective spine surgery: a retrospective analysis of a large surgical database.

Background: Allogeneic blood transfusion used to be common in spine surgery. Patient blood management has been widely adopted, and it is important to reassess transfusion predictors in contemporary practice.

Methods: A retrospective study of inpatient spine surgery was performed using National Surgical Quality Improvement Program (NSQIP) data from 2011 to 2019.

Epidural anesthesia needle guidance by forward-view endoscopic optical coherence tomography and deep learning.

Epidural anesthesia requires injection of anesthetic into the epidural space in the spine. Accurate placement of the epidural needle is a major challenge. To address this, we developed a forward-view endoscopic optical coherence tomography (OCT) system for real-time imaging of the tissue in front of the needle tip during the puncture.

[Neuraxial analgesia in a parturient with the VACTERL association undergoing labor and vaginal delivery].

Introduction: The term VACTERL is an acronym for an association of congenital malformations: including vertebral, anal, cardiac, tracheo-esophageal, renal and limb anomalies. VACTERL anomalies pose a formidable challenge to anesthesiologists. We describe the anesthetic management of a parturient with VACTERL association, who underwent neuraxial analgesia for labor and vaginal delivery.

Prolonged respiratory depression after general anesthesia in an adult with congenital rubella syndrome.

Congenital rubella syndrome (CRS) is caused by rubella virus infection of the pregnant mother leading to teratogenic effects on the fetus. Although rare in the developed world, manifestations reach far into adulthood and underscore the importance of careful evaluation before surgery. We present a case of an adult with CRS in whom unexpected prolonged postoperative respiratory depression occurred.
