چکیده
BACKGROUND The optimal hemoglobin level and transfusion threshold in patients with septic shock treated with an early, goal oriented approach to resuscitation remains unknown. AIMS To assess the impact of packed red blood cell (PRBC) transfusion on clinically relevant outcomes in patients with septic shock treated with early goal directed therapy (EGDT). SETTINGS AND DESIGN Retrospective cohort study of 93 patients who presented with septic shock, to a single center academic intensive care unit and received EGDT. MATERIALS AND METHODS Data were collected on patients identified via the Surviving Sepsis Campaign Chart Review database and linked to Project IMPACT database. The PRBC group and no PRBC group were compared by the Pearson chi-square and Fisher's exact test to analyze statistical significance. RESULTS The PRBC group had a mortality of 41.2% vs. 33.9% in the no PRBC transfusion group (P = NS). The PRBC group also had more mechanical ventilation days (11.2 days vs. 5.0 days, (P ≤ 0.05), longer hospital length of stay (25.9 days vs. 12.5 days, (P ≤ 0.05), and longer intensive care unit length of stay (11.4 days vs. 3.8 days, (P ≤ 0.05). CONCLUSIONS In this retrospective cohort study, transfusion of PRBCs was associated with worsened clinical outcomes in patients with septic shock treated with EGDT. Further studies are needed to determine the impact of transfusion of PRBC within the context of early resuscitation of patients with septic shock, as the beneficial effects gained by an early and goal oriented approach to resuscitation may be lost by the negative effects associated with PRBC transfusion.

Should we restrict erythrocyte transfusion in early goal directed protocols?
BACKGROUND Early goal-directed therapy has been endorsed in the guidelines of the Surviving Sepsis Campaign as a key strategy among patients presenting with severe sepsis or septic shock. But more importantly, early goal-directed therapy also became standard care for non-septic critically ill patients and was adopted for high-risk surgical patients. DISCUSSION Importantly, transfusion of red ...

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...

Early goal-directed therapy (EGDT) has become regarded as the standard of care for the management of patients with severe sepsis and septic shock. The elements of EGDT have been bundled together as the "Sepsis Bundle," and compliance with the elements of the bundle is frequently used as an indicator of the quality of care delivered. The major elements of EGDT include fluid resuscitation to achi...
متن کاملRed blood cell transfusion in the resuscitation of septic patients with hematological malignancies
BACKGROUND Indications for red blood cell (RBC) transfusion in septic acute circulatory failure remain unclear. We addressed the practices and the prognostic impact of RBC transfusion in the early resuscitation of severe sepsis and septic shock in patients with hematological malignancies. METHODS We performed a retrospective analysis of a prospectively collected database of patients with hema...

recommend a target haemoglobin of 7 to 9 g/dl to initiate blood transfusion [1]. In their rationale the authors use a subgroup of trauma patients from the Transfusion Require ments in Critical Care study; however, patients with active blood loss were excluded from this trial. Expressing a current opinion about transfusion and trauma patients, in 2006 McIntyre and Hebert wrote: 'It is important ...
