3Ventilation
• Avoidance of hypoxaemia.
• Normoventilation of trauma patients.
• Hyperventilation in the presence of signs of imminent cerebral herniation.
4Diagnosis and monitoring of bleeding
• Shock index (SI) = Heart Rate/Systolic BP
• Increased risk for transfusion
5Immediate intervention
and Further investigation
• Obvious bleeding source do and
control it.
• If no obvious source of bleeding
undergo immediate further
investigation.
• Focused assessment with
sonography in trauma (FAST)
• Contrast-enhanced ultrasound
(CEUS)
• Contrast-enhanced whole-body CT
(WBCT)

• Repeated Hb measurements as a laboratory marker for bleeding.
• ABGs -Serum lactate and/ or base deficit.
• Coagulation monitoring.
• Pt Ptt INR
• Platelet counts
• Clauss fibrinogen level
• Viscoelastic method (VEM)
Tissue oxygenation, volume, fluids
and temperature
Tissue oxygenation
6Volume replacement
• Restricted volume replacement strategy (1–1.5 L crystalloid)
• Permissive hypotension target systolic blood pressure of 80–90mmHg,
(mean BP 50–60mmHg) until Bleeding control.
• If GCS ≤ 8, keep mean BP ≥ 80 mmHg.
• Isotonic crystalloid solutions be initiated in the hypotensive bleeding
trauma patient.
• Balanced electrolyte solutions VS the avoidance of saline solutions.
• Hypotonic solutions such as Ringer’s lactate be avoided in patients with severe head
trauma.

7Massive Transfusion (MT)
• Defined as requiring the administration
of ≥3 units of red blood cells within any
hour of admission
• Adult Massive Transfusion Guideline:
• The blood bank should strive to deliver
plasma, platelets, and RBCs in a 1:1:1 ratio
• The blood bank will have 6 RBCs, 6 FFP, and a
6-pack of platelets.
• The MT will continue until stopped by the
attending physician.
• TASH Score
Schwartz’s Principles of Surgery Eleventh Edition: chapter 5 Shock, page 131- 156
• Hb target 70 to 90 g/L
• Reduce heat loss and warm the hypothermic patient
• Use warm (37°C to 40°C) IV solutions
