„The modern operation is safe for the patient. The modern surgeon must make the patient safe for the modern operation“
Lord Moynihan

Standard surgical practice (early total care): the best operation for a patient is one,
definitive procedure the first chance of any surgical intervention
is the best chance for any definitive repair or reconstruction
ER→OR→ICU

BUT!!!
Multiple trauma patients (ISS ≥35) are more likely to die from their intra-operative metabolic failure that from a failure to complete operative repairs
The death triad: - Hypothermia- Acidosis- Coagulopathy

One of the major advances in surgical technique in the past 20 years.
The most technically demanding and challenging surgery a trauma surgeon can perform.
approach method

ER→OR→ICU→OR→ICU

Hypothermia: Clinically important if less than 37*C for
more than 4 h Can lead to cardiac arrhythmias,
decreased cardiac output, increassed systemic vascular resistance
Can induce and exacerbate coagulopathy by inhibition of clotting cascade reaction
![Page 8: Damage Control Surgery Principles Dr. Josip Janković Dr. Boris Hrečkovski Department of surgery General hospital Slavonski Brod](https://reader033.vdocuments.net/reader033/viewer/2022061514/56649da95503460f94a968b3/html5/thumbnails/8.jpg)
Acidosis: Uncorrected haemorrhagic shock leads
into inadequate cellular perfusion, anaerobic metabolism and the production of lactatic acid
Interferes with blood clotting mechanisms and promotes coagulopathy and blood loss
![Page 9: Damage Control Surgery Principles Dr. Josip Janković Dr. Boris Hrečkovski Department of surgery General hospital Slavonski Brod](https://reader033.vdocuments.net/reader033/viewer/2022061514/56649da95503460f94a968b3/html5/thumbnails/9.jpg)
Coagulopathy: Hypothermia, acidosis and the
consequences of massive blood transfusion all lead to the development of a coagulopathy
Platelet dysfunction at low temperature Activation of the fibrinolytic system Haemodilution following massive
resuscitation

Parameters as a guideline for instituting damage control: pH less then or equal to 7.2 serum bicarbonate level less than or equal to 15 mEq/L core temperature less than or equal to 34*C transfusion volume of packed RBCs more than or equal to 4000 ml total blood replacement more than or equal to 5000 ml total fluid replacement more than or equal to 12 000 ml
If all - deathIf one - DCS

The principles of damage control surgery are:
Control haemorrhage
Prevention contamination
Avoid further injury
![Page 12: Damage Control Surgery Principles Dr. Josip Janković Dr. Boris Hrečkovski Department of surgery General hospital Slavonski Brod](https://reader033.vdocuments.net/reader033/viewer/2022061514/56649da95503460f94a968b3/html5/thumbnails/12.jpg)
Prehospital and emergency department times should be minimized
BTLS NO unnecessary and superfluous investigations Rapid transport to the operating room without
repeated attempts to restrore cisculating volume- they require operative control of haemorrhage and simultaneous vigorous resuscitation
![Page 13: Damage Control Surgery Principles Dr. Josip Janković Dr. Boris Hrečkovski Department of surgery General hospital Slavonski Brod](https://reader033.vdocuments.net/reader033/viewer/2022061514/56649da95503460f94a968b3/html5/thumbnails/13.jpg)
Stage 1 DCS (abdomen)
![Page 14: Damage Control Surgery Principles Dr. Josip Janković Dr. Boris Hrečkovski Department of surgery General hospital Slavonski Brod](https://reader033.vdocuments.net/reader033/viewer/2022061514/56649da95503460f94a968b3/html5/thumbnails/14.jpg)
initial laparotomy identify the main source of bleeding perihepatic packing (superior and inferior) small gastotomies and enterotomies can be
rapidly closed resect non-viable bowel and close the ends minor pancreatic injuries not involving duct- no
treatment distal injury including the panceratic duct- distal
pancreatectomy NO pancreaticoduodenectomy (drainage) abdominal closure is rapid and temporary- if
there is any doubt about abdominal compartment syndrome, left it open (silo-bag, vacuum-pack technique)

Stage 1 DCS (skeletal)
![Page 17: Damage Control Surgery Principles Dr. Josip Janković Dr. Boris Hrečkovski Department of surgery General hospital Slavonski Brod](https://reader033.vdocuments.net/reader033/viewer/2022061514/56649da95503460f94a968b3/html5/thumbnails/17.jpg)
Stable patient – osteosynthesis Polytrauma patient- FE Do not insist on anatomical reposition, but
on fracture stabilisation Open fracture-debridman Timing is individual considering clinical
state Secundary brain damage?

Stage 2 DCS
Begins in ICU The next 24 to 48 hours are crucial Correction of metabolic disorder Core rewarming Correction of coagulopathy Complete ventilatory support Correction of acidosis Identification of occult injury
![Page 19: Damage Control Surgery Principles Dr. Josip Janković Dr. Boris Hrečkovski Department of surgery General hospital Slavonski Brod](https://reader033.vdocuments.net/reader033/viewer/2022061514/56649da95503460f94a968b3/html5/thumbnails/19.jpg)
Stage 3 DCS – planned reoperation
Window of opportunity is 24-48 hours after the trauma- between the correction of metabolic disorder and the onset of SIRS and MOF
Removal of the abdominal packs (48-72 h) Primary repair with end-to-end anastomosis undertaken Copious washout should be performed and the abdomen
closed The patient sometimes needs early unplanned
reoperation-ongoing haemorrhage, abdominal compartment syndrome or peritontis
Window of opportunity for definitive osteosynthesis is 5-10 days after trauma

Complications of DCS
Abdominal compartment syndrome
General copmlications: wound sepsis wound dehiscence fistula formation ICU-related infections skin complications

DCS is a treathement method DCS is one of the major advances in surgical
technique in the past 20 years DCS is recognized all over the world for
treathing polytraumatized patients (ISS≥35) DCS is used in our hospital in the last 10 years Patients who had death rate according to
ISS≥90%, survived How much surgery polytrauma patient can
tolerate?
