Preoperative Hematocrit Levels and Postoperative Outcomes
in Older Patients Undergoing Noncardiac Surgery
Wu WC et al, JAMA 2007; 297:2481‒8
• Retrospective cohort study using the VA National
Surgical Quality Improvement Program database.
• 310,311 veterans aged ≥ 65 years who underwent
major noncardiac surgery between 1997 and 2004.
• Increased 30-day mortality in patients with
preoperative Hct < 39% (Hb < 13 g/dL).

•
The Lancet
Volume 378, Issue 9800, 15-21 October 2011, Pages 1362-1363
We obtained data for 227 425 patients, of whom 69 229
(30.44%) had preoperative anaemia.
• postoperative mortality at 30 days was higher in patients
with anaemia than in those without anaemia (odds ratio [OR]
1.42,; this difference was consistent in mild anaemia 1.41, and
moderate-to-severe anaemia (1.44, ) Composite postoperative
•
morbidity at 30 days was also higher in patients with
anaemia than in those without anaemia
When compared with patients without anaemia or a defined risk
factor, patients with anaemia and most risk factors had a higher
adjusted OR for 30-day mortality and morbidity than did patients
with either anaemia or the risk factor alone.
• Conclusion : Preoperative anaemia, even to a mild
degree, is independently associated with an
increased risk of 30-day morbidity and mortality
in patients undergoing major non-cardiac surgery

Detection, Evaluation and Management
of Preoperative Anemia in the Elective Orthopedic
Surgical Patient—NATA Guidelines
Multidisciplinary panel : 3 orthopedists , 3 hematologists,
6 anesthesiologists, 1 epidemiologist And society

Orthopaedics and Traumatology (EFORT) : G. Benoni

Recommendations―Detection of Anemia
• Recommendation 1: We recommend that
elective surgical patients have a Hb level
determination as close to 28 days before the
scheduled surgical procedure (Grade 1A).
• Recommendation 2: We suggest that the
patient’s target Hb before elective surgery
be within the normal range (normal female ≥
12 g/dL, normal male ≥ 13 g/dL), according to
WHO criteria (Grade 2C).
TL Goodnough Br J Anaesth. 2011 Jan;106(1):13-22
Belgrade 2011
Recommendations―Evaluation of Anemia
• Recommendation 3: We recommend that laboratory
testing take place to further evaluate for nutritional
deficiencies, chronic renal insufficiency, and/or chronic
inflammatory disease (Grade 1C).
• Recommendation 4: We recommend that nutritional
deficiencies be treated before surgery (Grade 1C).
• Recommendation 5: We suggest that erythropoiesisstimulating agent (ESA) therapy be used for anemic
patients in whom nutritional deficiencies have been
ruled out and/or corrected. (Grade 2A).

To sum up: at preoperative assessment
1. To increase Hb in this short delay (28
days), I need ESA
2. Because of ESA therapy, I need Iron
3. The choice of IV Iron is based on CRP,
if oral is not tolerated, if drug
interaction (thyroxin…), if renal
impairment..
4. In case of macrocytic RBC, I add Folic

Probability of Transfusion
Probability of Allogeneic-Only Transfusion
Preoperative EPO : « a first class
technique….. »
If Hb increases before surgical procedure:
• Blood loss tolerated without any transfusion
increases and thus we avoid any transfusion
(autologous and allogeneic)
• We can solve all the problems of the
controversy or close the debate about

Belgrade 2011
Residual an unknown emergent risk
Immuno-modulatory effect
Mistransfusion, bacterial contamination
Hepatitis, VIH….
Why do we always need to associate
Iron to ESA
1. Erythropoiesis stimulation increases need
of Iron,
2. Iron fixed to transferrin disappears
rapidly and Iron from ferritin serum
should be mobilized
3. Mobilisation is done very slowly even if
ferritin serum level is normal
4. Iron should be quickly delivered to
respond to demand of erythropoiesis
stimulated by EPO
Belgrade 2011
Iron deficiency leads to bad response to
ESA
• If anemia cannot be corrected by ESA, it
means that Iron is deficient or not well
absorbed (inflammatory disease…)
• Functional Iron deficiency = decrease of
TSAT < 20%
Belgrade 2011
In practice : How to prescribe Iron
in preoperative period ?
• If oral 200 à 300 mg/day
• 1 h before meals
• If IV between 500mg /each injection of
EPO, according to Iron status
• Drug interactions with oral Iron are not
well known (Thyroxin, cycline,
fluoroquinolone, diphosphonates…)

Optimizing EPO use
1.
Iron therapy added (200 to 300 mg/day if
oral medication) and 200-500mg/week if IV
2. Start first injection between 21 and 30 days
before surgery
3. Number of EPO injections should be related
to Hb baseline
• 4 injections if Hb =10g/dl
Hb level is
• 3 injections if Hb =11g/dl
accurate only if
• 2 injections if Hb =12g/dl

dose (600 UI /kg/week)
delay between first injection and surgery
Iron therapy is necessary :200mg/Day (if oral)
and 500mg/week if IV
2. EPO is indicated if 10 ≤ Hb baseline ≤ 13g/dl
3. Contraindications are all recent artery diseases
(MI, Stroke, severe HyperTension, arteritis…..)

related to Hb baseline

How to use IV IRON
1. In postoperative period, because

Within 30 days of random assignment, 415 patients
(5.0%) had a perioperative MI. Most MIs (74.1%)
occurred within 48 hours of surgery; 65.3% of
patients did not experience ischemic symptoms.
The 30-day mortality rate was 11.6% (48 of 415
patients) among patients who had a perioperative MI
and 2.2% (178 of 7936 patients) among those who did
not (P 0.001).
Among patients with a perioperative MI, mortality rates
were elevated and similar between those with (9.7%;
adjusted odds ratio, 4.76 [95% CI, 2.68 to 8.43]) and
without (12.5%; adjusted odds ratio, 4.00 [CI, 2.65 to
6.06]) ischemic symptoms

1. TA reduces bleeding and transfusion
after THR, TKR and spinal surgery
2. Important doses (≥30mg.kg-1 …) and many
bolus are more efficient
3. Good safety, but no important study
(>1000 patients) Nausea are possible if
perfusion is too fast (less than 30 min)
4. Cost /effective (1€/1g)

Threshold Haemoglobin Levels and the Prognosis of
Stable Coronary Disease: Two New Cohorts and a
Systematic Review and Meta-Analysis
20,131 people with a new diagnosis of stable
angina and no previous acute coronary
syndrome, and 14,171 people with first MI
who survived for at least 7 days were
followed up for a mean of 3.2 years
Conclusions: There is
an association between
low haemoglobin
concentration and
increased mortality.
A large proportion
of patients with
coronary disease have
haemoglobin
concentrations below
the thresholds of risk
defined here.

Conclusions
• Anemia should be viewed as a serious and
treatable medical condition rather than as an
abnormal laboratory value.
• Preoperative anemia management in elective
orthopedic surgery patients improves
outcomes.
• New paradigm : no anemia, no transfusion and
mortality should decrease
• Moreover, if you see patient 1 month before
elective surgery, you don’t need to postpone
surgery (stopping VKA, clopidogrel…..)
