New Rationale: John Bell, Textbook of Surgery, 1812

“ Is not this fear of hemorrhage uppermost in the minds of young surgeons? Were this one danger removed, he would go forward in his profession, almost without fear.”

INCIDENCE OF HEMORRHAGE IN THE OPERATING ROOM

Japanese Society of Anesthesiologists (JSA) annual survey (2003) - 1,367,790 pts from 782 hospitals Life-threatening hemorrhage (LTH) reported in

1,011 pts = 0.074% Irita K et al. Masui, 2005;54(1):77-86

Hemorrhagic complications in elective surgery - COMPARE™ data: N = 130,641

Incidence = 960/130,641 = 0.075% Data on file, COMPARE™, Haemonetics®

SOURCES OF LIFE-THREATENING HEMORRHAGE IN THE OPERATING ROOM

Main sources of bleeding were abdominal aorta (15.4%)

thoracic aorta (14%)

liver (12.6%)

intracranial (8.2%)

pelvic organs (8%)

coeliac/mesenteric artery (7.8%) and

lung (7.1%). Irita K et al. Masui, 2005;54(1):77-86

WHY DO PATIENTS BLEED IN THE OPERATING ROOM?

1. “IT’S A PART OF THE PROCEDURE.”

2. INADVERTENT INJURY: THE “OOPS” FACTOR?

THE “OOPS” FACTOR?

629 injuries trocar injuries from 1993 - 1996. 408 (65%) vascular, primarily aorta and vena cava.

Bhoyrul S et al. J Am Coll Surg.2001;192(6):677-83

FDA report of 1384 trocar injuries cited surgical technique, device problems and patient characteristics as contributing factors.

Fuller J et al. J Minim Invasive Gynecol, 2005;12(4):302-7

“Approximately 75% to 90% of intraoperative and early postoperative bleeding is due to technical factors.”

Marietta M et al.Transplant Proc.2006;38(3):812-4

11

THE “OOPS” FACTOR?

Up to 40% of all splenectomies are done for iatrogenic injury. Most common with left hemicolectomy, open anti-reflux procedures and left nephrectomy.

Cassart K & Munro A. J R Coll Surg Edinb,2002;47(6):731-41

7/404 (1.7%) vascular injuries during major renal and adrenal retroperitoneoscopic surgery

Meraney AM et al. J Urol. 2002;168(5):1941-4

54/480 (11% ) spine patients with intraoperative vascular injury. 45/54 (83%) minor. 83% involved exposure of L4-5.

Hamden AD et al. J Vasc Surg, 2008;48(3):650-4

12

LIFE-THREATENING HEMORRHAGE IN THE OPERATING ROOM: ASSOCIATED FACTORS

Factors associated with LTH Delayed decision making (15.6%)

Delayed admission to OR for surgery (16.3%)

Anesthesia management problem (28.1%)

Delayed arrival of blood products (25.5%)

Surgical management problem (16.3%). Irita K et al. Masui, 2005;54(1):77-86

PROCEDURE AND ERROR-RELATED BLEEDING

1. Procedures that involve cutting into the cardiovascular system may involve more risk, and errors do occur in the best of circumstances, but REMEMBER

2. Shed blood can be recovered, processed and returned to the patient for ALL these procedures, and

3. ALL these procedures can and have been done with minimal blood loss by using careful technique and meticulous hemostasis.

MICROVASCULAR BLEEDING AND OOZING - WHAT’S GOING ON ?

Quantitative and/or Qualitative problems with Platelets and/or Coagulation Factors

Drug effects and Interactions

Massive transfusion - dilution

Transfusion reaction Melting Ice Cream Truck sculpture by "The

Glue Society”, Australia

16

Platelets and Coagulation Factors - Quantitative Disorders

Hereditary Fanconi, Alport, Bernard-Soulier syndromes

Factor deficiencies - Hemophilia, Von Willebrand’s disease

Decreased production Vitamin B12 deficiency

Leukemia, Myelodysplastic syndrome

Sepsis

Liver failure

Increased destruction ITP, TTP, DIC, SLE, HUS

Dilutional Massive transfusion

17

Platelets and Coagulation Factors - Qualitative Disorders

Risk of Bleeding with Prophylactic Anticoagulation

Rivaroxaban v. enoxaparin in TKR % THR: Major bleeding TKR = 0.6%; 0.5%; THR = 0.3%; 0.1%

Lassen MR et al. N Engl J Med.2008;358(26):2776-86

Erikkson BI et al. N Engl J Med.2008;358(26):2765-75

Bleeding incidence = 6.7% with LMWH v. 2.7% with conventional heparin but all MINOR

Bergqvist D et al. Br J Surg. 1988;7599):888-91

High risk orthopedic surgery - no major bleeding in trial of LMWH v. UFH

Simmoneau G et al. Arch Intern Med.1993;153(13):1541-6

426 pts - all general anesthesia, all LMWH: 1/426 (0.2%) bleeding

Preoperative Strategies

Identify and record patient’s medications

Stop meds before surgery if possible…and safe

Convert from long acting/irreversible drug to reversible drug Coumadin to Heparin

Use smaller dose Pre-operative aspirin increases post-operative bleeding, but

this may be avoided by the use of aspirin doses <325 mg/day.

Sun JC et al. Eur Heart J, 2008;29(8):1057-71

Correct nutritional deficiencies

Use specific factors for hereditary disorders

Desmopressin for von Willebrand’s

21

What About Patients on Dual Therapy after PCI and Stenting?

Dual therapy = Clopidogrel and ASA

Risk of stent thrombosis increased if therapy is discontinued early, especially if surgical pt,

Silber S et al. Herz, 2008; 33(4):244-53

Chassot PG et al. Br J Anaesth. 2007;99(3):316-28

Best evidence says MUST continue therapy until stents are endothelialized

3 mos for bare metal stents; up to 1 yr for drug-eluting stents

Rate of bleeding and transfusion for CABG similar with/without cessation of clopidogrel Song SW et al. Circ J. 2008;72(4):626-32

Consider converting from irreversible drug (Clopidogrel) to reversible drug (Eptifibitide)

Consult the cardiologist!!!

22

Trauma, Transfusions and Recombinant Factor VIIa

380 patients in Level I & II trauma centers at risk of death from hemorrhage

Mean time from admission to rFVIIa = 4.6 hrs.

Average 18 units RBCs before rFVIIa

Death from hemorrhage = 30%

Predictors of poor response pH <7.2

Platelet count <100,000

Blood pressure </= 90mm Hg

“Precise role of rFVIIa in traumatic hemorrhage is unclear.”

“First, correct shock, acidosis and thrombocytopenia.”

Knudson MM et al, 2011, J Amer Coll Surg, 22:1, 87-95

Blood Loss and Transfusion are NOT the Same!

www.usaccc.org

24

Why Do We Transfuse? Historical Transfusion Standards

James Blundell (1812): transfuse only following life-threatening hemorrhage

Multiple authors (19th century - 1940’s): transfuse only following life-threatening hemorrhage or to treat severe anemia

Adams and Lundy (1941): transfuse to an H/H of 10/30 before surgery

Received knowledge (1941-1988): transfuse as deemed needed

NIH Consensus Conference(1988): transfuse based on clinical evidence and Hgb < 8 gm/dL

25

Rationale for Transfusion Over Time

1667 - Correct mental disturbances

Jean Baptiste Denis and surgeon Paul Emmerez transfused lamb’s blood into a 16 yr old boy to correct his “dull and lumpish spirit.”

Antoine Mauroy had “escaped from his wife’s control.”

Deaths and lawsuits lead to ban for 150 years.

26

Rationale for Transfusion Over Time

1818 - Preventing death from active blood loss James Blundell

performs 1st allogeneic human blood transfusion on post-partum women - 50% successful

1818 and on - Uncertainty We are “all at sea” on

this subject

27

Rationale for Transfusion 1880 - 1900

Reports on 243 transfusions for “severe hemorrhage” -

Life-saving in 40.9%.

Experiments in transfusion for “severe hemorrhage”

Jennings - Transfusion: 1884 Geo Crile, Sr. - Hemorrhage and Transfusion: 1899

28

Bernheim, Blood Transfusion, Hemorrhage and the Anemias, 1917

Death from hemorrhage can be prevented by transfusion

Surgery made possible by transfusion

BUT, only anecdotal evidence

Rationale for Transfusion 1880 - 1900 - II

•Risk of reaction = 1:2 or 3

•Success = volume and use of fresh, whole blood

•Cult of itinerant “surgical” transfusionists develops

30

Military experience with

fresh, whole blood

Immediate Life-Threatening Condition…AND Hemoglobin!

http://www.trauma.org/archive/resus/massive.html

If Hb > 10g/dl transfusion is rarely indicated.

If Hb < 7g/dl transfusion is usually necessary.

If Hb between 7 and 10 g/dl, clinical status, PvO2 and ER are helpful in defining transfusion requirements

WHAT DETERMINES RBC TRANSFUSION? THE “USUAL SUSPECTS”?

Blood loss? Most literature discusses

TRANSFUSION not BLOOD LOSS - they are not the same!!

Patient status Co-morbidities

Urgency of operation

Surgeon - experience, training and choice

Hemoglobin/Anemia

Female gender

Advanced age

The RBC Storage Lesion

Decreased oxygen delivery Loss of 2,3, diphosphoglycerate (2,3 DPG) shifts O2 dissociation curve to left = hemoglobin

attracts oxygen and holds onto it but doesn’t release it well. Suttner, Anesth Analg, 2004

Deformed cells RBCs lose flexibility and cannot get into the capillaries, thereby decreasing delivery of

oxygen to cells in need. Chin-Yee I and Spence RK, Blood Storage in: Perioperative Transfusion Medicine, 2006, eds. Spiess, Shander, Spence. P.

199-210.

Accelerated RBC death Stored RBCs die more quickly than fresh cells. They release free hemoglobin, a potent

vasoconstrictor. Vasoconstriction of capillaries decreases oxygen delivery to tissues. Luten M., Cell Mol Biol, 2004

The Older the Blood, the Worse the Outcome

Multiple studies in a variety of patients have shown that the age of the transfused blood has a negative impact on patient outcomes.

Giving MORE Blood Does NOT Improve Outcomes

The TRICC Trial: 357 ICU pts. randomized to maintenance of either 8 gm/dL (restrictive group) vs. 10 gm/dL (liberal group)

• Hébert et al. N Engl J Med. 1999;340:409-417

The PINT Trial: ELBW infants randomly assigned within 48 hrs of birth to maintenance of low or high Hgb transfusion thresholds.

Kirpalani H, J Pediatr, 2006;149(3):301-307

RBC transfusion to 8 gm/dL vs. 10 gm/dL in severe brain injury patients

George et al, Neurocrit Care, 2008;Feb 14

For ALL THREE TRIALS: Transfusion rate lower in restrictive groups

No statistically significant differences between groups in primary outcomes.

63

Benefit of Blood Products - What Can We Conclude?

Evidence of benefit from RBC transfusion is hard to find

Most benefit is assumed and not scientifically proven

Some patients will benefit from blood transfusion but we need to do a better job of identifying who they are

No prospective, randomized trials have ever been done to establish the life-saving benefit of RBC transfusion

Giving MORE blood is NOT better

As a result, many RBC transfusion are probably unnecessary

Patients transfused without need get RISK, not BENEFIT

All Blood Products Carry Risk

FFP PLATELETS

65

FFP and CRYO GUIDELINES

DO USE FFP FOR Single or multiple specific, diagnosed coagulation

factors deficiencies

DIC with bleeding

DO NOT USE FFP FOR Warfarin reversal

Vitamin K deficiency

To correct INR/PT/PTT in the absence of bleeding

Hypovolemia

DIC without bleeding

DO USE CRYO FOR Documented fibrinogen deficiency

DIC with bleeding

66

How Do I Prevent and/or Reduce Blood Loss?

• Halstedian principles

• Temporary vascular occlusion

• Stop bleeding, don’t use it as a guide to transfusion!

• “I HAD TO DO THIS QUICKLY, SO I IGNORED THE BLEEDING”

• Anatomic dissection • “IF IT BLEEDS WHEN YOU CUT

IT, IT’S A VESSEL!’

• CLAMP, THEN CUT!

• Experienced hands • SLOW BAD, FAST BAD, FAST

GOOD

• Preop embolization

• Staging of procedures

• CUSA, cautery, LASER, etc.

• Fibrin glues, etc.

• Laparoscopic and lap-assisted surgery

• Image-guided surgery

• Robotics

• Minimally-invasive, endovascular, etc.

67

Halsted’s Surgical Principles

Handle tissue gently

Dissect along anatomic planes

Maintain hemostasis

Use fine sutures

Use sharp dissection

68

“Next, an example of the very same procedure when done correctly!”

Know

The

Procedure!!

The surgeon has many tools available to control bleeding.

Know them and use them wisely.

THE MAIN REASONS WE TRANSFUSE

TO TREAT ANEMIA AND RAISE H&H

PHYSICIAN CHOICE

71

Blood Loss in Surgery - Basic Concepts

Most general surgical procedures can be done with minimal blood loss

Reducing surgical blood loss improves outcomes by reducing RBC transfusion

Allogeneic blood carries risk that can be avoided

Preoperative planning is essential for blood avoidance

72

WHAT CAN WE CHANGE IN OUR TRANSFUSION PRACTICE?

1. PREVENTION - WORDS HAVE POWER, SO STOP SAYING THE PATIENT “NEEDS” OR “REQUIRED” A TRANSFUSION

1. WHERE’S THE PROOF? WHY DID THE PT “NEED” A TRANSFUSION?

2. IF YOU CHOSE TO TRANSFUSE USE CLINICAL CRITERIA AND DOCUMENT BOTH YOUR REASONS AND RESULTS

1. ADD TO SURGICAL TIME-OUT?

3. IF ARE YOU TREATING A NUMBER, NOT A PATIENT

1. WHO FEELS BETTER - YOU OR THE PATIENT?

73

TREAT ANEMIA PREOP

Treatable anemia

should be a CONTRAINDICATION

to elective surgery.

74

Perioperative Blood Management Policies

Tolerate asymptomatic anemia

Transfuse on a case-by-case basis Document both rationale and results

Transfuse one unit at a time

Right blood to the right patient at the right time

Prevent and control blood loss

Use fresh, not stored, autologous blood

Maximize oxygen delivery

Restore RBC preop

Involve the patient

Follow policies and procedures

Track, measure and monitor
