GOALS
Review the anatomy of the abdomen Quadrants Peritoneal vs. Retroperitoneal Solid vs. Hollow organ Vascular structures
Assessment (History and Physical Exam) Management Abdominal trauma Special situations
3
The Abdomen
Everything between diaphragm and pelvis
Injury and illness can be very difficult to assess because of large variety of structures
4
Abdominal Anatomy
Abdomen divided into four quadrants by body mid-line, horizontal plane through umbilicus
Organs can be located by quadrant
5
Abdominal Anatomy
Right Upper Quadrant Liver Gall Bladder Right Kidney Ascending Colon Transverse Colon
6
Abdominal Anatomy
Left Upper Quadrant Spleen Stomach Pancreas Left Kidney Transverse Colon Descending Colon
7
Abdominal Anatomy
Right Lower Quadrant Ascending Colon Appendix Right Ovary (female) Right Fallopian Tube
(female)
8
Abdominal Anatomy
Left Lower Quadrant Descending Colon Sigmoid colon Left Ovary (female) Left Fallopian Tube
(female)
9
Abdominal Anatomy
Periumbilical area Located around (peri) the navel (umbilicus) Small bowel lies in all quadrants in periumbilical
area
Suprapubic area Located just above pubic bone Urinary bladder, uterus lie in this area
10
Abdominal Cavity
Peritoneum = abdominal cavity lining
Divides abdomen into two spaces Peritoneal cavity Retroperitoneal space
(retro=behind)
11
Abdominal Anatomy Retroperitoneal
Pancreas Kidney Ureter Inferior vena cava Abdominal aorta Urinary bladder Reproductive organs
Peritoneal Spleen Liver Stomach Gall bladder Bowel
NOTE: Disease or injury of retroperitoneal organs often causes
back pain.
12
Abdominal Anatomy
REVIEW: Organs are classified by Quadrant, periumbilical, or suprapubic Peritoneal or retroperitoneal
Organs can also be classified as: Solid Hollow Major vascular
13
Solid Organs
LiverSpleenKidneyPancreas
NOTE: When solid organs are injured, they bleed
heavily and cause shock.
14
Solid Organs
Liver Largest abdominal organ Most frequently injured Fractures of ribs 8-12 on right side Bleeding can be either:
Slow, contained under capsule Free into peritoneal cavity
15
Solid Organs
Spleen Frequently injured with
trauma ribs 9-11 on left side Bleeds easily Capsule around spleen tends
to slow development of shock Rapid shock onset when
capsule ruptures
16
Solid Organs
Pancreas Lies across lumbar
spine Sudden deceleration
produces straddle injury Very little hemorrhage Leakage of enzymes
digests structures in retroperitoneal space, causes volume loss, shock
17
Solid Organs
Kidney Retroperitoneal Vulnerable to trauma
(blunt & penetrating), infection, obstruction, chronic disease
Tenderness: Lower ribs, upper L-spine, flank
Pain: groin, shoulder, back, flank
18
Hollow Organs
StomachGall bladderLarge, small intestinesUreters, urinary bladder, urethra
Rupture causes content spillage & inflammation of
peritoneum.
19
Hollow Organs
Stomach Acid, enzymes Immediate
peritonitis Pain, tenderness,
guarding, rigidity
20
Hollow Organs
Colon Spillage of bacteria May take 6 hrs to develop peritonitis
Small Bowel Fewer bacteria May take 24-48 hours to develop peritonitis
21
Hollow Organs: Urinary System Ureters
Penetrating injury
Bladder Blunt injury (seatbelts, pelvic fracture)
Urethra Straddle injury
Signs and Symptoms Abnormal urination (Urgency, Inability, Dysuria,
Hematuria) Blood at external meatus Perineal bruising (butterfly bruise) Scrotal hematoma Shock Abdominal distension
22
Major Vascular Structures
AortaInferior vena cavaMajor branches
Injury can cause severe blood loss; exsanguination
(bleeding out).
23
QUESTIONS about Abdominal Anatomy?
24
ASSESSMENT of Abdominal Pain
History
LOCATIONWhere do you hurt?
Know locations of major organsBut realize abdominal pain
locations do not always correlate well with source
25
ASSESSMENT of Abdominal Pain
QUALITYWhat does pain feel like?
Steady pain - inflammatory processCrampy pain - obstructive process
26
ASSESSMENT of Abdominal Pain
ONSETWas onset of pain gradual or
sudden?Sudden = perforation, hemorrhage,
infarctGradual = peritoneal irritation,
hollow organ distension
27
ASSESSMENT of Abdominal Pain
RADIATIONDoes pain radiate (travel) anywhere?
Right shoulder, angle of right scapula = gall bladder
Left shoulder = spleen, stomachAround flank to groin = kidney,
ureter
28
ASSESSMENT of Abdominal Pain
DURATION > 6 hour duration = ? surgical significance
ASSOCIATED SYMPTOM: Nausea &/or vomiting? Bloody? “Coffee
Grounds”?
Any blood in GI tract = Emergency until proven otherwise
29
ASSESSMENT of Abdominal PainChange in urinary habits? Urine
appearance?
Change in bowel habits? Diarrhea? Appearance of bowel movements? Melena?
Regardless of underlying cause vomiting or diarrhea can be a problem because of
associated volume loss.
30
ASSESSMENT of Abdominal Pain
Females Last menstrual period? Abnormal vaginal bleeding?
In females, abdominal pain = Gynecological problem until proven
otherwise.
31
PHYSICAL EXAM
General Appearance Lies perfectly still inflammation = peritonitis Restless, writhing obstruction
Abdominal distension?Ecchymosis around umbilicus, flanks?
32
PHYSICAL EXAMVital signs
Tachycardia = Early shock &/or pain (more important than BP)
Rapid shallow breathing = peritonitis
33
PHYSICAL EXAM
Palpate each quadrant Work toward area of pain Warm hands Patient on back, knee bent (if possible) Note tenderness, rigidity, involuntary guarding,
voluntary guarding, masses
Bowel sounds (?)
34
Management
AirwayHigh concentration O2
Anticipate vomitingAnticipate hypovolemia
Need PIV, IVFNothing by mouth except medications
35
Management
Consider referred cardiac pain: Adults > 30 Diabetics History of cardiac problems
In females, consider gynecological problems, especially ruptured ectopic pregnancy (surgical emergency)
36
QUESTIONS about general assessment or management?
37
REVIEW: GOALS
Review the anatomy of the abdomen Quadrants Peritoneal vs. Retroperitoneal Solid vs. Hollow organ Vascular structures
Assessment (History and Physical Exam) Management
NEXT: Abdominal trauma Special situations
38
Abdominal Trauma
Most survive to reach hospitalMost common factors leading to death
Failure to adequately evaluate Delayed resuscitation Inadequate volume replacement Inadequate/missed diagnosis Delayed surgery
39
High Index of Suspicion in Trauma
MechanismUnexplained hypovolemic shock Signs of injured abdomen
Management
40
Mechanism
Look for signs of injury Bruises Tire marks Obvious open injuries
Trauma to lower chest, back, flank, buttocks, and perineum
Injury above umbilicus also involves chest until proven otherwise
41
Unexplained Shock
Assess vital signs; skin color, temperature; capillary refill
Tachycardia; restlessness; cool, moist skinIn trauma, signs of shock suggest
abdominal injury if no other obvious causes present
Assume any abdominal injury is serious until proven otherwise!
42
Signs of Injured Abdomen
Diffuse tenderness
Pain Pain referred to shoulder =
Organ under diaphragm involved (?spleen)
Pain referred to back = Retroperitoneal organ involved (?kidney)
43
Abdominal Trauma Management
Less important to diagnose exact injuryTreat clinical findings (open wounds,
hypotension/tachycardia)Management same regardless of specific
organ(s) injured
44
Abdominal Trauma Management
AirwayC-Spine if mechanism indicates High flow O2
Assist ventilations if neededGive nothing by mouth(?) MAST may be helpful in slowing
intraabdominal bleeding with shock
45
Special situations in Abdominal Pain
Impaled objectsEviscerationTrauma to the reproductive systemSexual assault
46
47
Impaled Object
Leave in place Shorten if necessary for transport Leave part of object exposed
48
Evisceration
With large laceration abdominal contents may spill out
Do NOT try to replace
49
Evisceration
Cover exposed organs with saline moistened multi-trauma dressing
Do NOT use 4 x 4sCover first dressing with second DRY
dressing or aluminum foil
50
Reproductive System Trauma
Can occur to both external and internal reproductive systems External
More common Pain, extensive bleeding
Internal Less frequently injured
Treat like blunt or penetrating soft tissue injuries elsewhere on body
51
Male Genitalia Trauma
Usually NOT life-threatening
Very painful Great source of
concern to patient
52
Male Genitalia Trauma
Avulsion of skin of penis, scrotum Cover with a moist,
sterile dressing
Complete amputation of penis Treat as any
amputated part
53
Male Genitalia Trauma
Blunt trauma to penis, scrotum Apply ice pack
Urethral foreign bodies Do NOT remove
Penis entrapped in zipper If 1 or 2 teeth involved, try to unzip If more involved, cut zipper out of trousers,
transport
54
Female Genitalia Trauma
Internal Rarely injured
External Can cause pain,
extensive bleeding Usually not life-
threatening
Treat with compresses, pressure
55
Sexual Assault
Avoid examining genitalia unless obvious bleeding present
Ask patient to NOT wash, douche, urinate, defecate
Ask patient NOT to change clothesRecord history, but avoid extensive
questioning about incident
56
SUMMARY: Abdominal Pain
Consider the anatomyIn general abdominal pain, note HISTORYIn trauma, think about mechanism
ManagementANTICIPATE! Vomiting=airway Hypovolemiaresuscitation Appropriate transport
