Pediatric TBI
Special considerations:

Large heads

Thinner pliable skull

Fontanels

Less myelination

Changes in cerebral blood flow

Brain injury
Primary injury
■ Diffuse vs focal
■ DAI, mTBI, EDH, SDH, SAH, IPH, etc.
Secondary injury
■ Edema and cell death following primary injury
Second insult
■ Hypotension, hypoxia, ICH, seizures, hyperthermia
*Goal of most of our interventions is to decrease secondary insult/injury
Optimize balance of energy in brain tissue

Moderate (GCS 9-12)
Severe (GCS 3-8)


Physical Exam

Radiological Exam
22

56
Accurate assessment of blood loss
Size-appropriate goals for resuscitation
Clear start and stop points
Patient safety – blood compatibility and availability
Early FFP to treat/prevent coagulopathy
Balanced ratio of products (1:1:1)
Provision of transfusion-related medications – Calcium,
Factor VIIa, TXA
Estimates of blood loss
Based on volume of blood product given to maintain
hemodynamic stability
■ Actual OR anticipated
Other relevant clinical parameters:
■ HR, BP, CVP
■ BD, lactate, pH
■ Hgb/Hct not a reliable indicator
57
Estimates of blood loss
At physician’s discretion, MTP can be initiated for either:
1.
Actual or anticipated transfusion of blood products AND
other IV fluids greater than the patient’s estimated blood
volume within 24 hour period
2.
Need for transfusion equal to half of the patient’s estimated
blood volume at one time
58
Estimates of blood loss

15 year old boy in a rodeo is stepped on by a bull. Initially
unconscious, transferred emergently to the local ED. Damage
control laparotomy, transfusion, air medical transport to Level 1
Trauma Center. On arrival, immediately back to OR. Massive
transfusion protocol initiated. Closure, to IR for embolization. To
ICU for supportive care. Elevated ventilator pressures and low
blood pressure.

Abdominal Compartment Syndrome
Def: the acute onset of tense abdominal distention with
associated renal, pulmonary and/or cardiovascular dysfunction
66
Abdominal Compartment Syndrome
Causes:

increased ICP

decreased preload & afterload

increased pulmonary pressures & resistance

renal dysfunction

gut dysfunction→ MODS

Grade and Interpretation
Grade IV - ACS
Abdominal Compartment Syndrome
Treatments:
•
A high index of suspicion for ACS
•
Prophylactic decompression
•
Immediate decompression
•
