Obstetric hemorrhage is a leading cause of maternal mortality worldwide. New concepts involving the pathophysiology of hemorrhage have been described and include early activation of both the protein C and fibrinolytic pathways. New tendencies in hemorrhage treatment include the use of hemostatic resuscitation. Massive transfusion protocols involve the early utilization of blood products and lim...

BACKGROUND AND AIMS Oncosurgeries may incur massive blood loss demanding frequent blood sampling to assess blood loss and the need for intraoperative blood transfusions. Accuracy of non-invasive spectrophotometric haemoglobin (hereafter to be referred as SpHb) monitoring has been studied in various perioperative settings. The intraoperative use of Radical-7®, Masimo Corp., (Radical-7®) for SpHb...

BACKGROUND Open simple prostatectomy has long been associated with large blood losses; hence allogeneic blood transfusion in this procedure is a standard practice world over. A review of literature suggests significant association between perioperative blood loss accompanying open simple prostatectomy and certain patient factors. The shortage of blood and blood products in our blood transfusion...

Since the onset of corona virus disease 2019 pandemic spectrum caused by severe acute respiratory distress syndrome 2 (SARS-CoV-2) has been found to be very wide with a myriad hematological manifestations. This chapter presents images peripheral blood features two patients kidney injury, which is part this spectrum. The from 15-year-old Iraqi patient β thalassemia major who was on regular trans...

Massive blood transfusion is defined as the loss of one or more circulating blood volumes. It is, therefore, important to calculate the patient’s estimated blood volume (EBV) and to relate this to the volume of blood products and other fluids administered (Table 1). In addition the anesthesiologist should estimate how much blood will be allowed to be lost before the initiation of packed RBC tra...
