Damage Control Resuscitation DCR

Damage Control Resuscitation DCR


Damage control resuscitation consist of 3 main component :


I.  Hemostatic resuscitation

II. Permeasive hypotension

III. Damage control surgery

I. Hemostatic Resuscitation

- early use of whole blood or combined replaced blood component.

Aim : prevent dilutional coagulopathy & treat intrinsic coagulopathy.

Recent study:

1. PRBC:FFP:Plt = 1:1:1

Result:

Increases number of survival of massive haemorrhage.

2. If plasma fibrinogen level <1.5g/L: give fibrinogen concentrate as part of massive transfusion protocol.

3. Recombinant factor VII

- if all other measure fail

- dosage: 100mcg/kg

4. Tranxaemic acid

- recommended as adjunct to reduce bleeding in trauma patient

According to Crash-2 Trial
  • dosage: IV 1g over 10min then 1g over 8H
  • reduced the mortality if given within 3H
  • reduced bleeding & mortality if given within 1H. 
Role of Thromboelastography and theomboelastometry in acute coagulopathy :
  • Assessment of coagulation deficiency
  • Used as point of care testing 
  • Currently recommended in massive transfusion protocol & hemostatic resuscitation. 

(II) Permeasive hypotension


" hypotension resuscitation"

- restriction fluid resuscitation until bleeding control.

- goal: SBP 90mmhg for adequate end organ perfussion.

- only useful in 1st hour following traumatic injury.

- evidence only in penetrating injuries

Contraindicated in
  •  TBI 
  • Child <12 year
  • Blast injury 
Goal directed therapy:

1. SBP 90mmhg

2. HR <100

3. Urine output >0.5mls/kg/hour


Recommendation :

Bolus of 250mls & monitor response of CVP , MAP , pH of central venous , SVCO2 >70%

Which fluid?

0.9% NS according to  NICE studies.

Concern :

Bleeding not control

Fluid resuscitation to normal BP might be harmful as exacerbating ongoing haemorrhage by dislodge the clots.

Adverse effect :

Regional hypoperfussion , eg splanchic hypoperfussion

(III) damage control surgery

  • Stop haemorrhage 
  • Avoid contamination 
  • Optimize physiological function 
Rapid initiation surgery and hemostasis , definitive surgery done later.
