1. PHYSICAL ASSESSMENT OF THE ABDOMEN Dr. Beverly Fineman
Nursing 309
3. Overview of abdominal structure. large oval cavity
extends from diaphragm to symphysis
viscera: solid and hollow
4. Landmarks for the abdominal examination four quadrants
nine sections
bony landmarks
muscles
5. More landmarks Bony landmarks on the anterior body include:
xiphoid process of sternum
costal margin, midline, umbilicus, anterior iliac spine, poupart’s ligament, superior margin of pubis
Posterior landmark
costovertebral angle
6. Abdominal assessment Preparing the exam room
preparing the patient
positioning the examiner
7. Assessment Techniques
inspection
skin: color, scars, veins, lesions, umbilicus
umbilical hernia, bleeding, inflammation
8. Continued inspection
contour of the abdomen:flat,rounded, protuberant,scaphoid
symmetry
enlarged organ
masses
peristalsis,pulsation,distention
9. distention -Definition: unusual stretching of
abdominal wall
note position of umbilicus
note portion of abdomen that is
distended
reasons for distention:flat(obesity),
flatus(gas), feces, fluid,
fetus(pregnancy or tumor)
10. Auscultation Where it occurs in abdominal assessment
listening for bowel sounds to assess motility
normal sounds
abnormal sounds
how and where to listen
11. Auscultation continued Auscultation performed before
palpation and percussion
Use diaphragm of stethoscope
Listen to bowel sounds
Normal sounds are clicks and
gurgles, irregular, 5-30 times per minute
Influenced by digestion
12. More on Auscultation Increased bowel sounds are due to hypermotility of peristalsis
Decreased are due to paralytic ileus or peritonitis
intestinal obstruction can present with increased or decreased sounds
13. Additional Sounds Always listen in hypertensive patient
Bruits:
Bruits are low pitched, vascular sounds, resembling murmur
Caused by partially obstructed artery– turbulence
Listen in epigastrum and each upper quadrant
Listen in costovertebral angle(with patient seated)
Listen over aorta, iliac arteries, femoral arteries
Arterial insufficiency in legs
14. PERCUSSION Assessment technique used to assess size and density of organs in the abdomen
Examples: used to measure size of liver or spleen
15. More on percussion Used to identify masses
Used to identify air in stomach or in bowel
Used alone or in conjunction with palpation or to validate palpatory findings
Orient yourself to the abdomen by lightly percussing all 4 quadrants for tympany or dullness
tympany usually predominates due to gas in the bowel
16. Percussion Continued Dullness may be present due to feces or fluid or over organs or a solid mass
Develop a specific percussion route and stick to it.
To percuss the liver or estimate its size:
in right midclavicular line, start below the umbilicus with tympany and percuss upward toward liver dullness.
Mark to indicate the liver border
17. Liver Percussion In the right midclavicular line, percuss down from lung resonance to liver dullness. This indicates the lower border of the liver
Mark this and measure between the two lines
This is the height of the liver What is the average liver span in the right midclavicular line?
In the midsternal?
What is the mean span for males? For females?What is the average liver span in the right midclavicular line?
In the midsternal?
What is the mean span for males? For females?
18. More about percussion Percussion provides most accurate clinical measurement of liver size as a gross measurement
19. Percussing the spleen Where is the spleen located?
in the curve of the diaphragm just posterior to the left midaxillary line
When the spleen enlarges, it does so anteriorly, downward and medially. This will replace the tympany of the stomach and colon with dullness
20. Tricks to Assessing the Spleen Percuss in the lowest interspace in the left anterior axillary line for tympany.
Ask the patient to take a deep breath and percuss on inspiration.
the percussion note should remain tympanic
A change to dullness suggest spenomegally
This is known as a positive splenic percussion sign
21. Another trick Percuss in several directions away from tympany or resonance to dullness
outline edges
a large dull area suggests splenomegally
22. Other Findings To differentiate amongst fat, gas, tumor or ascites:
fat—tympany with scattered areas of dullness
gas—distention with tympany
tumor—dullness with tympany
ascites—fluid seeks the lowest point in the abdomen. Flanks are dull to percussion with tympanic center. There is a protuberant abdomen with bulging flanks
23. Assessing for Ascites With patient lying supine, find tympany in center of abdomen
From center of abdomen, percuss outward in several directions to denote dullness
To test for “shifting dullness,” ask patient to turn to one side, then percuss from tympany to dullness
fluid will sink to lowest point
24. More on ascites Assess for fluid wave
Puddle sign
25. Assessing for kidney tenderness Find the costovertebral angle
This is the angle formed by the lower border of the 12th rib and the transverve processes of the upper lumbar vertebrae
Place left hand flat in this area on one side, hit the hand sharply with the fist of the other. Patient will admit to tenderness if present.
Repeat on the other side
26. PALPATION Used to assess muscle tone, tenderness, fluid, organs
May be light or deep
Use pads of fingertips in light dipping motions and avoid short jabs Nails should be shortNails should be short
27. Palpation cont. To differentiate voluntary from involuntary resistance: rectus muscle will relax with expiration.
Palpation is light or deep
Deep palpation used to define and delineate organs or abdominal masses.
Use palmar surface of fingers and feel in all four quadrants
28. Deep palpation If masses are felt, note: location, size, shalpe, consistency, tenderness, pulsations, mobility with respiration or with hand.
If patient is obese or rigid, use 2 hands to palpate
Place one on top of other and feel with lower hand
29. The bladder Bladder percussion is unnecessary unless there is a suspicion of urinary retention
Palpate above the symphysis
An empty bladder is not palpable
30. Palpation of the liver Stand on patients right side
Place left hand behind patient parallel to and supporting 11-12th ribs
Patient should relax
Press your left hand forward and place your right hand on abdomen with fingertips below lower edge liver dullness
Press in and up while patient takes deep breath; if palpable, liver should come down What does a normal liver edge feel like? Abnormal?
If you can’t feel it, start lower and try again
Ask patient to use abdominal breathingWhat does a normal liver edge feel like? Abnormal?
If you can’t feel it, start lower and try again
Ask patient to use abdominal breathing
31. Palpation cont. Liver hook
Kidney: not palpable in normal adult
May be able to feel lower right kidney pole in very thin person
32. The spleen The spleen is usually not palpable
From patient’s right side, reach over and around under patient with your left hand
Place right hand below left costal margin and press in toward spleen. Ask patient to take deep breath---will feel if palpable
33. Assessing for peritoneal irritation Ask patient to cough. Palpate lightly with one finger over area of pain produced by cough
Test for REBOUND TENDERNESS: press finger in firmly and slowly then quickly withdraw. Rebound tenderness mean the withdrawal has caused the pain--- not the pressure
Other: Psoas sign and Obturator sign, cutaneous hyperesthesia
34. Assessing the Aorta Press firmly deep in upper abdomen slightly to left of midline.
Feel for aortic pulsations
Determine width of aorta by pressing deeply on either side of aorta
What is the normal width of the aorta?
If pulsatile mass is found, feel for femoral pulses which may be dimished.
35. This concludes the examination of the abdomen
36. Examination of the anus and rectum This information is sometimes included with the abdominal assessment and at times with assessment of the male and female genitalia.
For our purposes, we are including it here
37. General Principles Anal canal is outlet of GI tract
3.8cm long
Merges with rectal mucosa @ anorectal junction
Sensory nerves in anal area responsible for pain due to trauma
38. Sphincters 2 concentric layers of muscle that keep anal canal closed
Internal sphincter
under involuntary control by autonomic nervous system
External sphincter
surround internal sphincters
under voluntary control
Intersphincteric groove: palpable separation between internal and external sphincter
39. MORE THAN YOU WANT TO KNOW: Anal columns - -folds of mucosa extend vertically from rectum and end in anorectal junction
Can be seen with scope
Each column contains and artery and vein
40. hemorrhoids With increased venous (portal) pressure, vein can enlarge.
this is a hemorrhoid or a varicosity
External hemorrhoids occur below the anorectal junction
itch and bleed with defecation
painful and swollen with thrombosis
resolve and leave flabby skin top around
anal opening.
41. continued Internal hemorrhoids originate above anorectal junction
covered with mucosa
may appear as red mass with pressure (valsalva)
