Q

Trauma laparotomy

A

Drape clavicle to knee

Large incision

Evacuate clot

Eviscerate small bowel

Examine for any major bleeding

Haemostatic packing

Under left diaphragm

Left paracolic gutter

Pelvis

Right paracolic gutter

Subhepatic space

Above and lateral to liver

Remove packs one at a time, starting at area least likely to be bleeding

Apply pressure, compress organ that is bleeding

Allow anaesthetist to ‘catch up’

Perform definitive packing and haemorrhage control

Packs should provide sufficient pressure to tamponade venous bleeding but preserve arterial flow

Copious washout

Replace small intestine

Perform temporary abdominal closure if required

Q

Trauma thoracotomy

A

Procedure

airway doctor advances ET tube into R main bronchus

long L thoracotomy incision (5th space) initially Costochondral junction (1-2cm from edge of sternum) to mid-axillary line ±extended across sternum if required

use Finochietto retractor (with handles/bar pointing downward, to allow access to RHS if required)

displace lung medially – ask anaesthetist to collapse lung

surface markings: 3 fingerbreadths below the nipple → 2 fingerbreadths below the tip of the scapula → midpoint between med border of scapula & the vertebral column (≈ edge of erector spinae muscles)

INJURIES

Go chest wall lungs heart & great vessels

Examine chest wall for intercostal or internal thoracic bleeding

Pericardial tamponade: identify phrenic nerve, open pericardium anterior to phrenic nerve in craniocaudal fashion (can make a small nick & tear – less likely to damage nerve), evacuate clot, plug hole in heart (finger, IDC, suture, skin stapler)

Close cardiac defect with 3/0 or 4/0 Prolene (on SH needle) – Teflon pledgets/ horizontal mattress suture

Tears close to coronary arteries must be sutured with vertical mattress suture so don’t oversew artery

Satinsky clamp to bleeding atria

Not essential to close pericardium on completion of procedure

Lung laceration: aortic/Satinsky clamp across area of bleeding (hilum if necessary); tell the airway doc so that ventilation can be adjusted, control bleeding lung

attempt at repair x2 if no success → stapled pneumonectomy

tractotomy with suture ligation of blood and air leaks is an option

Hypovolemic asystole: clamp descending aorta just above diaphragm

Incise pleura ant & post to aorta, separate from oesophagus, clamp just the aorta at the level of the diaphragm – no more than 30 minutes

Reduces exsanguination & increases flow to coronaries

internal cardiac massage: use the flat of your hands, one in front one behind (as using your fingertips can penetrate the heart); use internal paddles if defibrillation is required

±aspirate RA for air

When to stop:

injuries are irreparable (eg blunt cardiac rupture)

volume replacement not achieved within 15mins of thoracotomy (ie heart remains empty)

heart is not in a self-sustaining rhythm after 30mins

Q

Operating room thoracotomy

A

Indications (typically following penetrating trauma)

massive hemothorax (>1500ML blood drained immediately from chest tube)

on-going bleeding (>200mL/hour for 2-4hrs, on-going transfusion requirement)

cardiac tamponade, confirmed by echo, pericardiocentesis or subxiphoid window

sig undrained hemothorax following chest drain insertion warrants thoracoscopy or thoracotomy to evaluate

specific injury requiring surgical intervention (eg tracheobronchial, oesophageal)

persistent air leak

Retained FB

Procedure:

(NB useful to place an NG (to aid in palpation of the oesophagus, cf flat aorta))

pt supine, L thoracotomy ±can “clam shell” across to RHS

to cut across sternum: use heavy scissors or Leibsche knife (pronounced “Lipshi”; looks like a chisel, that you “hammer” to cause it to cut) and be aware of internal mammary a’s (tie them off)

alternative: median sternotomy (using Leibsche knife or circular saw)

use Finochietto retractor (with handles/bar pointing downward, to allow access to RHS if required)

the supradiaphragmatic aorta can be cross-clamped (after first dividing & clearing the mediastinal pleura that covers it; the inferior pulmonary ligament may also have to be divided to gain access)
