3. INTRODUCTION
⢠Greek word 'tpavua', trauma= injury
⢠injury (in + jus, 'not right') or wound
⢠structural alteration and/or physiologic imbalance
⢠most common cause of death for all individuals
between the ages of 1 and 44 years
⢠third most common cause of death regardless of age
4. Common causes Blunt Trauma Abd.
⢠Motor vehicle crash,
⢠Fall,
⢠Assault,
⢠Crush
⢠Recreational accidents
â blunt trauma is associated with multiple widely
distributed injuries
5. Mechanism of Blunt Trauma
⢠Result from the impact force and deformation
related to deceleration and compression
⢠Impact force = magnitude and duration
⢠Deformation = strain
⢠Strain
â Compressive/ crushing:
â Shearing /opposing:
â Tensile /stretching
⢠Strain > elasticity or viscosity = disruption/injury
6. Pattern of injury
⢠Solid organ laceration
â spleen (40-55%), liver (35-45%), kidney ,pancreas
⢠Tear or avulsion of mesentery /pedicle of solid organ 5%
⢠Rupture of small bowel or colon 5-10%
⢠GU injuries
⢠Vascular injury
⢠Fracture of Pelvis / Ribs n vertebrae
⢠Diaphragmatic rupture
⢠Abrasion/ laceration
8. HISTORY
⢠Mechanism of blunt trauma
⢠Time and place of injury
⢠Magnitude of force/Speed of Vehicle
⢠Status of other vehicle occupant
⢠Patientâs position in vehicle
⢠Duration of entrapment
⢠Use of protective gears/ safety devices
⢠Presence of alcohol or drug uses
⢠Presence of psychiatric illness
10. EXAMINATION
⢠General Physical Examination
⢠Systematic Abdominal examination
â Abrasions, ecchymosis, seat belt abrasions or contusion
,distension
â Generalized tenderness, rebound tenderness, guarding ,
rigidity,# ribs
â tympany in gastric dilatation or free air; dullness with
hemoperitoneum
â Bowel sound/ bowel sound in thorax
⢠DRE
â evaluate sphincter tone and to look for blood, perforation, or
a high-riding prostate
11.

13. ⢠Grey-Turner sign:
Bluish discoloration of lower flanks, lower back; associated
with retroperitoneal bleeding of pancreas, kidney, or pelvic
fracture.
⢠Cullen sign:
Bluish discoloration around umbilicus, indicates peritoneal
bleeding, often pancreatic hemorrhage.
⢠Kehr sign:
L shoulder pain while supine; caused by diaphragmatic
irritation (splenic injury, free air, intra-abd bleeding)
⢠Balance sign:
Dull percussion in LUQ. Sign of splenic injury; blood
accumulating in subcapsular or extracapsular spleen.
⢠Seatbelt sign:
results from compression from an improperly positioned (too
high, over the abdomen instead of the bony pelvis) lap
seatbelt in a motor-vehicle crash
14. SEAT BELT SYNDROME
⢠first described by Chance in 1948
⢠resulting from hyperflexion of the spine about a fixed
axis anterior to the vertebral column. It includes
â # posterior process and/or the body of the lumbar spine,
â fractures of the neck of the pancreas and
â avulsions of the small-bowel mesentery
⢠Many trauma surgeons consider a true seatbelt sign as
an indication for operation, as it is associated with such a
high incidence of visceral injury.
15. PROBLEM IN EVALUATING
⢠altered sensorium (injury to the brain, ingestion of
alcohol or illicit drugs);
⢠altered sensation (injury to the spinal cord);
⢠injuries to adjacent structures (ribs, pelvis,
thoracolumbar spine); or
⢠physical examination is equivocal.

73. SPLENORRAPHY
⢠Aim - control of bleeding and to avoid causing or
leaving behind infarcted splenic tissue.

effective.

â meticulous hemostasis;
â watertight repair of the collecting system;
â adequate drainage of the renal bed
â tension-free spatulated anastomosis,
â and good urinary drainage with ureteral stents
and/or nephrostomy tubes
100. ⢠90% Blunt renal injuries Rx nonoperatively
⢠Minor (grade I and II) injuries are properly
treated by observation.
⢠Renovascular injuries n destructive
parenchymal injuries with hypotension
requires operative Rx
101. ⢠Parenchymal renal injuries are treated with
hemostatic and reconstructive techniques
⢠The collecting system should be closed
separately, and the renal capsule should be
preserved to close over the repair of the
collecting system
⢠For destructive parenchymal or irreparable
renovascular injuries, nephrectomy may be the
only option
102. URETERAL INJURY
⢠Injuries to the ureters are uncommon but may
occur in patients with pelvic fractures
⢠methylene blue or indigo carmine iv used to
delineate the site of injury.
⢠In DCS, the ureter can be ligated on both
sides of the injury and a nephrostomy tube
placed
103. Distal Ureteral injury
â Debridement n reimplantation faciliated with a posas hitch
n /or Boari flap
â transureteroureterostomy
Mid n Upper Ureter injury
â The injured midureter is best repaired by primary
anastomosis . / transureterouretrostomy
For extensive damage

Most anastomoses after repair of ureteral injury should
be stented for 3- 4 wks
104. UB INJURY

⢠Fractured pelvis is the injury most commonly associated
with a ruptured bladder (at least 80 per cent).
Type of injury
⢠extraperitoneal extravasation
â Anterior wall injury
⢠Intrapertoneal extravasation
â Posterior wall injury/ rent in dome
⢠Injury best diagnosed with contrast study
105. ⢠Bleeding from a contused bladder usually resolves with
drainage by urethral catheter.

all operative Rx.
110. VASCULAR INJURY
⢠blunt trauma most commonly involves renal
vasculature and rarely the abdominal aorta.
⢠Blunt avulsions of the SMA are rare but should be
considered in patients with a seat belt sign
⢠blunt injuries are typically intimal tears of the
infrarenal aorta and are readily exposed via a direct
approach.
⢠Heparinized saline (50 u/l) is injected
⢠To avoid future vascular-enteric fistulas, the vascular
suture lines should be covered with omentum
111. ⢠Arterial repair should always be done for the aorta
,superior mesenteric, proper hepatic, renal, iliac,
femoral, and popliteal arteries.
⢠Venous repair should be attempted for injuries of the
superior vena cava, the inferior vena cava proximal to
the renal veins, and the portal vein, although the
portal vein may be ligated in extreme cases.
⢠Follow-up imaging is performed 1 to 2 weeks after
injury to confirm healing.
