Erroneously low continuous ScvO2 reading due to red blood cells transfusion
نویسندگان
چکیده
Hemoglobin oxygen saturation in superior vena cava (ScvO(2)) is used as a parameter to guide hemodynamic management in shock patients and it can be continuously read through a central venous catheter equipped with a fiberoptic spectrophotometric probe (Edwards PreSep catheter) connected to a specific monitor (Edwards Vigileo). We report of an episode of erroneous ScvO(2) reading by this technology in a patient with septic shock who was receiving an erythrocytes transfusion through the PreSep catheter main lumen. We think this artifact should be known by intensivists since it can lead to ScvO(2) misinterpretation and subsequent erroneous therapeutic decisions.

In-hospital mortality following treatment with red blood cell transfusion or inotropic therapy during early goal-directed therapy for septic shock: a retrospective propensity-adjusted analysis
INTRODUCTION We sought to investigate whether treatment of subnormal (<70%) central venous oxygen saturation (ScvO2) with inotropes or red blood cell (RBC) transfusion during early goal-directed therapy (EGDT) for septic shock is independently associated with in-hospital mortality. METHODS Retrospective analysis of a prospective EGDT patient database drawn from 21 emergency departments with a...
متن کاملTransfusion of Red Blood Cells Is Associated With Improved Central Venous Oxygen Saturation But Not Mortality in Septic Shock Patients
BACKGROUND Although the optimum hemoglobin (H) concentration for patients with septic shock (SS) has not been specifically investigated, current guidelines suggest that H of 7 - 9 g/dL, compared with 10 - 12 g/dL, was not associated with increased mortality in critically ill adults. This contrasts with early goal-directed resuscitation protocols that use a target hematocrit of 30% in patients w...

Background: Many of the multiple traumatized patients who refer to the hospital need transfusion. Transfusion-related acute lung injury (TRALI) is a serious clinical syndrome associated with the transfusion of plasma-containing blood components. In the article, we present a case of TRALI following transfusion of packed red blood cells Case Presentation: A 24 year old male referred to Shahid Beh...
متن کاملA Root Cause Analysis of Haemolysis Encountered in Leuco-filtration of Stored Packed Red Cells Units
Background and Aims: Leukoreduction of blood components has reduced the incidence of transfusion-associated adverse events. Leucofiltration is the most effective method of leukoreduction. We encountered haemolysis in a series of leucofiltered units. This stressed our precious inventory, added to financial loss, increased our turn-around time to issue leucofiltered blood units, and placed doubts...

Background: It is not clear whether the use of volumetric peristaltic infusion pumps, affect the quality of the erythrocytes during packed cell transfusion or not. In the present study in vitro quality of red blood cells was assessed after using this type of infusion pumps in a prospective study. Materials and Methods: In this study 60 units of packed red cells were examined before and after p...
