Review Article
Efficacy of red blood cell transfusion in the critically ill:
A systematic review of the literature*
Paul E. Marik, MD, FACP, FCCM, FCCP; Howard L. Corwin, MD, FACP, FCCM, FCCP
In recent years red blood cell
(RBC) transfusion requirements
in western nations has been in-
creasing because of the increasing
burden of chronic disease in an aging
population, improvement in life-support
technology, and blood-intensive surgical
procedures (1, 2). In the United States
alone, nearly 15 million units of blood are
donated and 13 million units are trans-
fused annually (2). For much of the last
(3). On the other hand, it is now becom-
ing clear that there are other important,
less recognized risks of RBC transfusion
related to RBC storage effects and to im-
munomodulating effects of RBC transfu-
sions, which occur in almost all recipi-
ents (4). These immunomodulating*See also p. 2707.

Background: Red blood cell (RBC) transfusions are common in
intensive care unit, trauma, and surgical patients. However, the
hematocrit that should be maintained in any particular patient
because the risks of further transfusion of RBC outweigh the
benefits remains unclear.
Objective: A systematic review of the literature to determine
the association between red blood cell transfusion, and morbidity
and mortality in high-risk hospitalized patients.
Data Sources: MEDLINE, Embase, Cochrane Register of Con-
trolled Trials, and citation review of relevant primary and review
articles.
Study Selection: Cohort studies that assessed the independent
effect of RBC transfusion on patient outcomes. From 571 articles
screened, 45 met inclusion criteria and were included for data
extraction.
Data Extraction: Forty-five studies including 272,596 were
identified (the outcomes from one study were reported in four
separate publications). The outcome measures were mortality,
infections, multiorgan dysfunction syndrome, and acute respira-
tory distress syndrome. The overall risks vs. benefits of RBC
transfusion on patient outcome in each study was classified as (i)
risks outweigh benefits, (ii) neutral risk, and (iii) benefits out-
weigh risks. The odds ratio and 95% confidence interval for each
outcome measure was recorded if available. The pooled odds
ratios were determined using meta-analytic techniques.
Data Synthesis: Forty-five observational studies with a median
of 687 patients/study (range, 63–78,974) were analyzed. In 42 of
the 45 studies the risks of RBC transfusion outweighed the
benefits; the risk was neutral in two studies with the benefits
outweighing the risks in a subgroup of a single study (elderly
patients with an acute myocardial infarction and a hematocrit
<30%). Seventeen of 18 studies, demonstrated that RBC trans-
fusions were an independent predictor of death; the pooled odds
ratio (12 studies) was 1.7 (95% confidence interval, 1.4؊1.9).
Twenty-two studies examined the association between RBC
transfusion and nosocomial infection; in all these studies blood
transfusion was an independent risk factor for infection. The
pooled odds ratio (nine studies) for developing an infectious
complication was 1.8 (95% confidence interval, 1.5–2.2). RBC
transfusions similarly increased the risk of developing multi-
organ dysfunction syndrome (three studies) and acute respiratory
distress syndrome (six studies). The pooled odds ratio for devel-
oping acute respiratory distress syndrome was 2.5 (95% confi-
dence interval, 1.6–3.3).
Conclusions: Despite the inherent limitations in the analysis of
cohort studies, our analysis suggests that in adult, intensive care
unit, trauma, and surgical patients, RBC transfusions are associated
with increased morbidity and mortality and therefore, current trans-
fusion practices may require reevaluation. The risks and benefits of
RBC transfusion should be assessed in every patient before transfu-
sion. (Crit Care Med 2008; 36:2667–2674)

A
dministration of packed red
blood cells (PRBCs) has been
associated with morbidity and
mortality for both medical and
surgical patients (1–13). Transfusions are
(2, 8) and long-term mortality (12). Gong
et al. (14) recently demonstrated the as-
sociation between PRBC transfusion and
the development and increased mortality
from acute respiratory distress syndrome.
Our objectives were 1) to exam
whether each unit of PRBC transfu

morbid outcomes in a large homo
Objective: Our objective was to quantify incremental risk asso-
ciated with transfusion of packed red blood cells and other blood
components on morbidity after coronary artery bypass grafting.
Design: The study design was an observational cohort study.
Setting: This investigation took place at a large tertiary care
referral center.
Patients: A total of 11,963 patients who underwent isolated
coronary artery bypass from January 1, 1995, through July 1,
2002.
Interventions: None.
Measurements and Main Results: Among the 11,963 patients
who underwent isolated coronary artery bypass grafting, 5,814
(48.6%) were transfused. Risk-adjusted probability of developing
in-hospital mortality and morbidity as a function of red blood cell
and blood-component transfusion was modeled using logistic
regression. Transfusion of red blood cells was associated with a
risk-adjusted increased risk for every postoperative morbid ev
mortality (odds ratio [OR], 1.77; 95% confidence interval
1.67–1.87; p < .0001), renal failure (OR, 2.06; 95% CI, 1.87–2
p < .0001), prolonged ventilatory support (OR, 1.79; 95%
1.72–1.86; p < .0001), serious infection (OR, 1.76; 95% CI, 1.68–1
p < .0001), cardiac complications (OR, 1.55; 95% CI, 1.47–1
p < .0001), and neurologic events (OR, 1.37; 95% CI, 1.30–1.44;
.0001).
Conclusions: Perioperative red blood cell transfusion is
single factor most reliably associated with increased risk
postoperative morbid events after isolated coronary artery byp
grafting. Each unit of red cells transfused is associated w
incrementally increased risk for adverse outcome. (Crit Care

Transfusion of fresh frozen plasma in critically ill surgical patients
is associated with an increased risk of infection

Objective: To determine whether there is an association be-
tween transfusion of fresh frozen plasma and infection in criti-
cally ill surgical patients.
Design: Retrospective study.
Setting: A 24-bed surgical intensive care unit in a university
hospital.
Patients: A total of 380 non-trauma patients who received
fresh frozen plasma from 2004 to 2005 were compared with 2,058
nontrauma patients who did not receive fresh frozen plasma.
Interventions: None.
Measurements and Main Results: We calculated the relative
risk of infectious complication for patients receiving and not
receiving fresh frozen plasma. T-test allowed comparison of av-
erage units of fresh frozen plasma transfused to patients with and
associated pneumonia without shock (relative risk 1.97, 1.03–
3.78), bloodstream infection with shock (relative risk 3.35, 1.69–
6.64), and undifferentiated septic shock (relative risk 3.22, 1.84–
5.61). The relative risk for transfusion of fresh frozen plasma and
all infections was 2.99 (2.28–3.93). The t-test revealed a signifi-
cant dose-response relationship between fresh frozen plasma and
infectious complications (p ‫؍‬ .02). Chi-square analysis showed a
significant association between infection and transfusion of fresh
frozen plasma in patients who did not receive concomitant red
blood cell transfusion (p < .01), but this association was not
significant in those who did receive red blood cells in addition to
fresh frozen plasma. The association between fresh frozen
plasma and infectious complications remained significant in the
multivariate model, with an odds ratio of infection per unit of

COMPLICANZE

Blood transfusions are also one of the largest
cost centers in hospitals. While the material
cost of blood ranges from $200 to $300 per
unit, the additional costs from storage, labor,
and waste result in an actual cost per unit
between $522 and $1,183.10 In addition to the
cost of blood itself, each unit of blood
transfused increases the cost of care, with even
higher costs incurred when patients are
transfused at higher hemoglobin levels.11

While blood transfusions can be life-saving, they can also be associated
with risks ranging from worse patient outcomes to death. The evidence of

recommendations on interventions, practices, and methods aimed at
reducing overuse in these clinical areas.
Introduction
Sometimes overlooked or neglected as a leading contributor to problems
with quality and patient safety, overuse of medical interventions affects
millions of patients.1
Overuse has been described as the provision of
treatments that provide zero or negligible benefit to patients, potentially
exposing them to the risk of harm. While many medical procedures are
associated with tradeoffs between benefits and risks, the risks that are
incurred in instances of overuse are not balanced by benefits to patients.
Five subject areas that have triggered concerns about overuse and quality
were addressed by work groups convened for the summit by The Joint
Commission and the American Medical Association-Convened Physician
Consortium for Performance Improvement®
(PCPI®
):
• Antibiotics are often prescribed to treat viral upper respiratory infections

Figure 6. Examples of Fixed Volume Bowls*
*Bowls for different machines/processing volumes also exist.
The fixed volume bowl rotates at speeds of up to 6,000rpm, and processes the salvaged
blood in fixed volume batches. As anticoagulated whole blood is pumped into the spinning
bowl, the centrifugal force separates the blood into its components as the bowl fills. As
more blood is pumped into the bowl the RBCs are retained in the bowl while the
supernatant, which is made up of the remaining components plus the anticoagulant, is
expressed through the outlet port and into the waste bag.
When the machine detects an adequate amount of RBCs within the bowl, a wash solution
of IV normal saline (0.9% NaCl) is pumped into the bowl passing through the red cell layer
and displacing most of the remaining non
red cell component into the waste bag.
Excess IV normal saline (0.9% NaCl) is also
expressed through the outlet port and into

Figure 8. Variable Volume Disk System
The variable volume disk (dynamic disk)
system is similar in principle to the fixed
volume bowl in the separation of RBCs
through centrifugation and washing
with IV normal saline (0.9% NaCl).
However, this system has an elastic silicone
diaphragm which permits a variable
volume of RBCs to be processed, i.e. it
does not require a set volume of RBCs for
processing to take place. The elastic
silicone diaphragm changes shape and size
during processing so that the machine
delivers an end product of variable volume
with a fixed haematocrit (Hct). The variable
volume disk system will process 100ml of
reservoir contents at a time. If the volume
of RBCs being drawn into the disk from the
reservoir is under 15mls, the system will
concentrate several batches of blood
before washing. This system is therefore
more advantageous for procedures where
lower volume blood losses occur or during
long procedures where the blood loss is
constant and slow.

The continuous rotary system works by continuously removing the supernatant and
concentrating and washing the RBCs. It requires only a very small volume of blood loss
to process, however, this does not automatically mean processing should progress.
The decision to process should always be made on an individual patient basis.
6.4 Stages of the Process
Opposite (Figure 10) is a description of each of the four main processing stages of the ICS

anticoagulated before it enters the collection reservoir. If the rate of flow of the
anticoagulant is insufficient, the salvaged blood will clot. This may result in contamination
of the processed blood and/or may prevent processing. Types of anticoagulant used are:
• Heparin saline:
– 30,000iu heparin/1,000ml intravenous (IV) normal saline (0.9% NaCl)
– Heparin works by activating Antithrombin III which in turn inactivates both Factor
Xa and Factor IIa (Thrombin) in the coagulation cascade (Figure 11). This prevents
the conversion of Fibrinogen to Fibrin and the formation of clots.
– The recommended ratio is approximately 1:5 e.g. 20ml of anticoagulant to 100ml
of blood (check your machine manufacturer recommendations)

(i.e. when the suction tip is immersed in a pool of blood), even high vacuum levels do not
result in excessive RBC haemolysis. This supports increasing vacuum levels during excessive
bleeding.
However, when blood and air are aspirated, as occurs naturally during most of the ICS
process, even low vacuum levels result in excessive haemolysis and therefore reduces the
available RBCs for reinfusion.

PROCEDURE:
The efficiency of red cell recovery by cell salvage is very much dependent
on the ability to recover the blood lost in a useable form. During surgery,
blood loss can be removed from the operative site by a combination of
suction and swabs. Blood loss to swabs during surgery has been estimated
at between 30%1
and 50%2
of the total surgical blood loss. By washing
swabs, the blood that is normally discarded can be collected and the overall
efficiency of red cell recovery improved.3

reinfusion of salvaged blood was continued without the LDF and no hypotension occurred. This is a
recognised complication which may be related to elevated levels of interleukin 6 [71], and is reviewed
by Sreelakshmi [72].
Learning points
The use of leucodepletion filters (LDF) with cell salvaged blood can, rarely, cause significant
hypotension
Stopping the infusion and resuscitation with fluids and vasopressors may be necessary although
all reports describe only transient hypotension
In cases where there is brisk haemorrhage and the blood is needed, try infusing without the LDF

Summary. The use of intraoperative cell salvage and autologous blood transfusion has
become an important method of blood conservation. The main aim of autologous
transfusion is to reduce the need for allogeneic blood transfusion and its associated
complications. Allogeneic blood transfusion has been associated with increased risk of
tumour recurrence, postoperative infection, acute lung injury, perioperative myocardial
infarction, postoperative low-output cardiac failure, and increased mortality. We have
reviewed the current evidence for cell salvage in modern surgical practice and examined
the controversial issues, such as the use of cell salvage in obstetrics, and in patients with
malignancy, or intra-abdominal or systemic sepsis. Cell salvage has been demonstrated to
be safe and effective at reducing allogeneic blood transfusion requirements in adult
elective surgery, with stronger evidence in cardiac and orthopaedic surgery. Prolonged use
of cell salvage with large-volume autotransfusion may be associated with dilution of
clotting factors and thrombocytopenia, and regular laboratory or near-patient monitoring
is required, along with appropriate blood product use. Cell salvage should be considered in

The National Blood Service for England col-
lects, tests, processes, stores, and issues 2.1
million blood donations each year, and the
optimal use of this scarce resource is of para-
mount importance. Allogeneic red blood cell
(RBC) transfusion is associated with well-
known adverse effects. These include febrile,
anaphylactic, and haemolytic transfusion reac-
tions, transfusion-related acute lung injury, and
transfusion-associated circulatory overload. In
addition, although rare, there are infection risks
of viral, bacterial, parasitic, or prion trans-
mission. In the laboratory setting, allogeneic
involves filtering and washing to remove con-
taminants. Red cells are retained, while the
plasma, platelets, heparin, free haemoglobin,
and inflammatory mediators are discarded with
the wash solution. This process may be discon-
tinuous or continuous, and the resulting red
cells are finally resuspended in normal saline at
a haematocrit of 50–70%, and reinfused into
the patient. Once primed, the cell salvage
machine should be used within 8 h to prevent
infective complications.

It is important to keep in mind that during the course of
most operations, a bacteremia is present related to the surgical
trauma. Broad-spectrum antibiotics are routinely used to man-
age this routine bacteremia. Several studies have suggested
that these drugs add additional safety when contaminated sal-
vaged blood is readministered.23,24
Dzik and Sherburne,25
in a review of the controversies sur-
rounding blood salvage, pointed out that allogeneic transfu-
sion leads to an increase in infection rate and that when faced
with bacterial contamination of salvaged blood, a clinical
decision needs to be made as to which therapy offers the
least risk to the patient. Known risk exists with allogeneic
blood, yet only theoretical risk is associated with salvaged
blood. Until data is generated supporting the theoretical risk
of salvaged in these circumstances, it seems reasonable to
avoid the known risk of allogeneic blood through the use of
blood salvage.
Obstetrics
One of the leading causes of death during childbirth is
hemorrhage, so the use of blood salvage would naturally
be attractive26,27
When applying blood salvage during the

bacteria, amniotic fluid, and fetal blood. Amniotic fluid con-

USO CS IN UROLOGIA
Intraoperative red blood cell salvage during
radical prostatectomy or radical cystectomy
1 Guidance
1.1 Intraoperative red blood cell salvage is an
efficacious technique for blood replacement and
its use is well established in other areas of surgery.
The evidence on safety is adequate. The
procedure may be used during radical
prostatectomy or radical cystectomy provided
normal arrangements are in place for clinical
governance and audit.
1.2 Clinicians wishing to undertake intraoperative red
blood cell salvage during radical prostatectomy or
radical cystectomy should ensure that patients
understand the possible risks and benefits of the
procedure compared with those of allogeneic
blood transfusion, and provide them with clear,
written information. In addition, use of the
Institute’s information for patients (‘Understanding
NICE guidance’) is recommended (available from
www.nice.org.uk/IPG258publicinfo).
2.2 Outline of the procedure
2.2.1 Blood lost during radical prostatectomy or radical
cystectomy is aspirated from the surgical field
using a suction catheter. The blood is then filtered
to remove debris. The filtered blood is washed or
spun and the red blood cells are resuspended in
saline, for transfusion during or after the
operation. A leukocyte depletion filter is nearly
always used; this is thought to minimise the risk of
re-infusion of malignant cells that may be present
in the aspirate. A number of different devices are
available for this procedure.

Intraoperative red blood cell salvage during
radical prostatectomy or radical cystectomy
1 Guidance
1.1 Intraoperative red blood cell salvage is an
efficacious technique for blood replacement and
its use is well established in other areas of surgery.
The evidence on safety is adequate. The
procedure may be used during radical
prostatectomy or radical cystectomy provided
normal arrangements are in place for clinical
governance and audit.
1.2 Clinicians wishing to undertake intraoperative red
blood cell salvage during radical prostatectomy or
2.2 Outline of the procedure
2.2.1 Blood lost during radical prostatectomy or radic
cystectomy is aspirated from the surgical field
using a suction catheter. The blood is then filter
to remove debris. The filtered blood is washed o
spun and the red blood cells are resuspended in
saline, for transfusion during or after the
operation. A leukocyte depletion filter is nearly
always used; this is thought to minimise the risk
re-infusion of malignant cells that may be prese
in the aspirate. A number of different devices a
available for this procedure.

ABSTRACT
Objectives. To evaluate the risk of long-term biochemical recurrence for patients who receive cell-salvaged
blood. Radical retropubic prostatectomy (RRP) is historically associated with the potential for significant
blood loss. Different blood management strategies include blood donation, hemodilution, preoperative
erythropoietin, and intraoperative cell salvage (IOCS). Oncologic surgeons have been reluctant to use IOCS
because of the potential risk of tumor dissemination.
Methods. We retrospectively analyzed an RRP database and compared those who did and did not receive
cell-salvaged blood by baseline parameters, pathologic outcomes, and biochemical recurrence. We also
stratified our patients according to the risk of recurrence.
Results. A total of 1038 patients underwent RRP between 1992 and 2003. Of these, 265 (25.5%) received
cell-salvaged blood and 773 (74.5%) did not. The two groups had similar baseline characteristics. No
differences were found between the two groups when compared by risk of seminal vesicle invasion or
positive surgical margins. Those who received cell-salvaged blood had a lower risk of extraprostatic
extension. The median follow-up for all patients was 40.2 months. The overall risk of biochemical recurrence
at 5 years for those who did and did not receive cell-salvaged blood was 15% and 18%, respectively (P ϭ
0.76). No significant differences were found in the risk of biochemical recurrence when patients were
stratified according to low, intermediate, and high risk.
Conclusions. IOCS is a safe and effective blood management strategy for patients undergoing RRP. The risk
of biochemical recurrence was not increased for those who received cell-salvaged blood. Concerns about
spreading tumor cells by way of IOCS would seem unwarranted. UROLOGY 65: 730–734, 2005. © 2005

INTRAOPERATIVE CELL SALVAGE IN RADICAL
RETROPUBIC PROSTATECTOMY

ABSTRACT
Objectives. To investigate the efficacy and safety of intraoperative cell salvage with autotransfusion using
leukocyte reduction filters in patients undergoing radical retropubic prostatectomy (RRP).
Methods. Between September 1996 and March 1999, 62 patients (age range 48 to 70 years) with clinically
localized prostate cancer underwent RRP with intraoperative cell salvage as the sole blood management
technique. Salvaged blood was passed through a leukocyte reduction filter before autotransfusion. The 62
cell salvage patients were compared with a cohort who predonated 1 to 3 U autologous blood (n ϭ 101). The
estimated blood loss, preoperative and postoperative hematocrit, need for homologous transfusion, and
biochemical recurrence rates were compared between the two groups. The progression-free survival rates
were compared using the Kaplan-Meier method.
Results. No difference was found in preoperative prostate-specific antigen level, pathologic stage, or
estimated blood loss between the cell salvage and autologous predonation groups. The preoperative and
postoperative hematocrit levels were higher in the cell salvage group (42.7% versus 39.6% and 31.3%
versus 27.9%, respectively; P Ͻ0.001 for each). The homologous transfusion rates were lower in the cell

teria may have differed. Because both cohorts un-
derwent surgery in the 1990s, after the require-
ments for transfusion were made more stringent,
this is unlikely. Our criteria, namely symptomatic
anemia or Hct less than 30% in patients with car-
diac disease, were identical for both groups.
CONCLUSIONS
ICS is an effective and safe technique for blood
management in patients undergoing radical pros-
tatectomy. Compared with patients using autolo-
gous blood predonation, it results in higher preop-
erative and postoperative Hct levels and a lower
homologous transfusion rate. Additionally, ICS
does not appear to increase early biochemical re-
currence rates in radical prostatectomy patients.

Intraoperative blood salvage in cancer surgery:
safe and effective?

Abstract
To support blood supply in the growing field of cancer surgery and to avoid transfusion induced immunomodulation
caused by the allogeneic barrier and by blood storage leasions we use intraoperative blood salvage with blood irra-
diation. This method is safe as it provides efficient elimination of contaminating cancer cells, and as it does not
compromise the quality of RBC. According to our experience with more than 700 procedures the combination of blood
salvage with blood irradiation also is very effective in saving blood resources. With this autologous, fresh, washed RBC
a blood product of excellent quality is available for optimal hemotherapy in cancer patients.

1. Introduction
The demand for blood in cancer surgery is high
and increasing. Problems with the supply of com-
patible blood are not uncommon in these patients
that previously have seen surgery and transfusions.
Some transfusion risks are especially relevant to
cancer patients like immunomodulation with im-
donations suffers from the poor predictability of
intraoperative blood loss leading to a waste of
autologous blood, or to insufficient supply. Im-
munosuppression is not only caused by the allog-
eneic barrier, but also by cell lesions during blood
storage at low temperature [2], relevant to both
allogeneic and autologous banked blood. In ad-
dition, growth factors are released during storage

Addition of factor IX concentrates may be most useful in
the highest risk Jehovah’s Witness patients.

EXPANDED USE OF RED CELL SALVAGE USING CENTRIFUGATION
Class IIb.
1. In high-risk patients with known malignancy who
require CPB, blood salvage using centrifugation of
blood salvaged from the operative field may be
considered since substantial data support benefit in
patients without malignancy, and new evidence
suggests worsened outcome when allogeneic trans-
fusion is required in patients with malignancy.
(Level of evidence B)
In 1986, the American Medical Association Council on
Scientific Affairs issued a statement regarding the safety
of blood salvage during cancer surgery [228]. At that
time, they advised against its use. Since then, 10 obser-
vational studies that included 476 patients who received
blood salvage during resection of multiple different tumor
types involving the liver [229–231], prostate [232–234],
uterus [235, 236], and urologic system [237, 238] support the
use of salvage of red cells using centrifugation in cancer
patients. In seven studies, a control group received no
transfusion, allogeneic transfusion, or preoperative autolo-
