INTRODUCTION
Abdominal injuries are common in patients who
sustain major trauma.
Unrecognized abdominal injuries are frequently
the cause of preventable death.
Approximately one-fifth of all traumatized pt
requiring operative intervention havesustained trauma to the abdomen.

Abdominal trauma
Abdominal trauma is an injury to the
abdomen. It may be blunt or penetrating
and may involve damage to the abdominalorgans.

TYPES OF INJURIES
Blunt abdominal trauma is a leading
cause of morbidity and mortality among all
age groups.Blunt trauma: liver spleen (most common).
Penetrating: liver, small bowel andstomach.
Penetrating: present with single or multiple
injuries

Penetrating abdominal trauma (PAT) is
usually diagnosed based on clinical signs,blunt abdominal trauma is more likely to be
missed because clinical signs are less
obvious.
Penetrating trauma is further subdivided
into stab wounds and bullet wounds, whichhave different treatments.

Multiple injuries, abdominal trauma can
lead to hemorrhage, hypovolemic shock, anddeath. Yet even a serious, life-threatening
abdominal injury may not cause obvious signs
and symptoms, especially in cases of blunttrauma.

Key responses to decrease mortality and
morbidity include :
- aggressive resuscitation efforts,
- adequate volume replacement,
- early diagnosis of injuries, and- surgical intervention if warranted

Mechanisms of injury
Forces applied to solid organ can rupture asurrounding capsule & injury the
parenchyma as well. Structures attached by ligaments or blood
vessels may be stressed at their attachment
points

PATHOPHYSIOLOGY
Blood loss: (mesenteric attachments of the
intestines ) semi fixed by ligaments, stressed,
tears , bleeding.
Liver & spleen ( rich blood supply) &
capsulated , compression, rupture, hemorrhage.
Pain: rigidity, spasm, rebound tendernessIrritants(blood or gastric contents or enzymes)

Pancreatic & duodenal injury: diffuse
abdominal, tenderness and pain radiating from
epigastric to the back.
Splenic injury: referred shoulder pain (Kehr`s
sign) . Because of: stress, blood in the abdominal
cavity and direct bowel injury

Spleen injury is usually associated with blunt
trauma. Fractures of ribs 10 to 12 on the left
should raise your suspicion of spleen damage,
which ranges from laceration of the capsule or
a nonexpanding hematoma to ruptured
subcapsular hematomas or parenchymallaceration.

Liver injury is common because of the
livers size and location.Severity ranges from a controlled
subcapsular hematoma and lacerations of the
parenchyma to hepatic avulsion or a severeinjury of the hepatic veins. ( )

Because liver tissue is very friable and the
liversblood supply and storage capacity areextensive, a patient with liver injuries can
hemorrhage profusely and may need surgery
to control the bleeding.

The most common kidney injury is a
contusion from blunt trauma; suspect thistype of injury if your patient has fractures of
the posterior ribs or lumbar vertebrae.

Other renal injuries include lacerations
or contusion of the renalparenchyma caused by shearing
and compression forces; the deeper
a laceration, the more serious the bleeding.

Deceleration forces may damage the renal
artery; collateral circulation in that area islimited, so any ischemia is serious and may
trigger acute tubular necrosis.

Hollow organ injuries, which can occur with
blunt or penetrating trauma, most commonlyinvolve the small bowel. Deceleration
with shearing may tear the small bowel,
generally in relatively fixed or looped areas

Blunt forces cause most bladder injuries. Thebladder rises into the abdominal cavity when
full, so its more susceptible to injury. If a
distended bladder ruptures or is perforated,
urine is likely to escape into the abdomen.

If the bladder isntfull when ruptured, urine
may leak into the surrounding pelvictissues, vulva, or scrotum.

Genitourinary tract - Perinephric hematomas
should be entered only after vascular controlhas been obtained. Repair of many renal
injuries (including partial nephrectomy) is
now possible. When nephrectomy is
required, it is reassuring to know that the
contra lateral kidney is functioning.

Diaphragmatic injuries are notoriously
difficult to diagnose. Small diaphragmatic
injuries on the right side may heal withoutincident, and the liver protects against
potential hernias. Small injuries on the left
side may result in symptomatic diaphragmatichernias. Acute diaphragmatic defects are best
approached through the diaphragm.

Colon/Rectum - In contrast to military
teaching, an increasing number of surgeonsutilize primary repair for simple colon
injuries without associated shock or
significant fecal soilage. Even a small
missed colon injury may be lethal

As always, your primary priorities are to
maintain thepatientsairway, breathing, andcirculation. Next, perform a rapid neurologic
examination and assess him head to toe
to identify obvious injuries and signs of
prolonged exposure to heat or cold.
10/14/2014 46
-
8/10/2019 5607TNCC-Abdominal trauma.ppt
47/65
Ask the patient (or his family, emergency
personnel, or bystanders) about his historyallergies, medications, preexisting medical
conditions, when he last ate, and events
immediately preceding or related to his
injury.

If your patient sustained blunt trauma, as in a
motor vehicle crash (MVC), keep his neck
and spine immobilized until X-rays rule out aspinal injury. If his viscera are protruding,
cover them with a sterile dressing moistened
with 0.9% sodium chloride solution to preventdrying.

are routine for a patientwith abdominal trauma:
10/14/2014 49

8/10/2019 5607TNCC-Abdominal trauma.ppt
50/65
Insert two large-bore intravenous
(I.V.) lines to infuse 0.9% sodium
chloride or lactated Ringers solution,according to facility protocol.
10/14/2014 50

8/10/2019 5607TNCC-Abdominal trauma.ppt
51/65
Control thepatientspain without sedating
him, so you can continue to assess hisinjuries and ask him questions. Generally,
I.V. analgesics such as morphine can
adequately manage pain without sedation.

Insert an indwelling urinary catheter, unless
you suspect a urinary tract injury. Forexample, bloody urine or a prostate gland
found to be in a high position during
a rectal exam could indicate damage to theurinary tract

Insert a gastric tube to decompress the
patients stomach, prevent aspiration, and
minimize leakage of gastric contents andcontamination of the abdominal cavity. This
also gives you access to gastric contents to
test for blood

The FAST option Focused abdominal
sonography for trauma (FAST) offers 98% to
100% specificity in blunt abdominal trauma,and is accurate 98% of the time. FAST is
especially helpful for pregnant patients or those
bleeding from multiple injuries.
Its also useful in identifying pericardial
fluid in penetrating trauma.

FAST can demonstrate the presence
or absence of pericardial fluid, abdominalfluid, and some parenchymal injuries via a 2-
to 3-minute exam. A hand-held transducer is
positioned on four key areas to evaluatefluid collection.

Unstable patients with penetrating
abdominal trauma, such as gunshotwounds, stab wounds, or other
impalements, usually proceed directly
to the operating department without
DPL or FAST.
