Effectiveness of a Calculation-Free Weight-Based Unfractionated Heparin Nomogram With Anti-Xa Level Monitoring Compared With Activated Partial Thromboplastin Time.

Ann Pharmacother 2021 May 23;55(5):575-583. Epub 2020 Sep 23.

VA Center for Health Equity Research and Promotion, Pittsburgh, PA, USA.

Background: Accurate monitoring of intravenous unfractionated heparin (UFH) is essential to mitigate the risk of adverse drug events associated with dosing errors. Although recent data support anti-factor Xa (anti-Xa) monitoring preferentially over activated partial thromboplastin time (aPTT) to improve time to therapeutic anticoagulation, the utility of incorporating anti-Xa monitoring with a calculation-free weight-based UFH nomogram has not been formally evaluated.

Objective: The primary objective of this study was to evaluate the time to therapeutic anticoagulation of a calculation-free weight-based UFH nomogram integrated with anti-Xa monitoring versus a historical control of aPTT monitoring utilizing manual dose calculations. Read More

Transfusion support in patients with sickle cell disease.

Semin Hematol 2020 04 28;57(2):39-50. Epub 2020 Jul 28.

Division of Transfusion Medicine, Department of Pathology, Vanderbilt University Medical Center, Nashville, TN, USA; Division of Hematology and Oncology, Department of Pediatrics, Vanderbilt University Medical Center, Nashville, TN, USA.

Blood transfusions are an integral component of the management of acute and chronic complications of sickle cell disease. Red cells can be administered as a simple transfusion, part of a modified exchange procedure involving manual removal of autologous red cells and infusion of donor red cells, and part of an automated red cell exchange procedure using apheresis techniques. Individuals with sickle cell disease are at risk of multiple complications of blood transfusions, including transfusional hemosiderosis, auto- and alloimmunization to minor red cell and human leukocyte antigens, delayed hemolytic transfusion reactions, and hyper-hemolysis.
