Indications for DRE?
Rectal haemorrhage or defects Spinal cord injury Pelvic fracture Blood at meatus or haematoma perineal Intraperitoneal hemorrhage
26
TEG Thromboelastogram ?
R time - coagulation factors => FFP k time - fibrinogen => cryoprecipitate Alpha - fibrinogen => cryoprecipitate MA - platelets => plts or DDAVP Lysis - cyclokapron
27
Head injury principles ? Neuroprotection
1. BP - no hypotension ! 2. Blunt intubation response 3. Prevent hypoxia/ hypercapnia/ hyperthermia and hypoglycemia Head up 30’ Sedation and analgesia Hyperventilation? Osmotherapy - hypertonic saline (3% 3ml/kg over 10mins) - mannitol Craniectomy Hypothermia Barbiturates / phenytoin LP
28
E-FAST quick review
1. Lung slide / m-mode 2. Cardiac pericardial fluid >1cm / serial scans 3. RUQ / morrisons pouch 4. LUQ / least likely to see fluid here 5. Suprapubic
29
E-FAST algorithm ?

Hypovolaemia Oxygenation Tension Tamponade
31
Indications for thoracotomy
CPR<10mins Witnessed sign of life within unit Penetrating trauma
32
Thoracotomy
1. Intubate - advance ETT into right bronchus (ventilate right lung) 2. ICD 3. Clamshell or rib spreader 4. Visualize heart and careful phrenic nerve 5. Find injury and occlude 6. Cardiac massage 7. Call surgeon
33
REBOA ?
Resuscitative endovascular balloon occlusion of the aorta (REBOA) involves the temporary occlusion of the aorta, using a percutaneously deployed intravascular balloon, usually inserted via the femoral artery.

55
Spinal shock vs neurogenic shock
Spinal shock - bulbocavernosus reflex first to return - Flaccidity and loss of reflexes Neurogenic shock - Dx of exclusion -loss of vasomotor tone - above T6 level - hypotension - bradycardia - warm peripheries Mx - fluids (often don’t respond) - Noradrenaline / adrenaline - atropine / pacing
