Transcript of Abdomen mich
The digestive system or tract is basically a long tube that begins with the mouth or oral cavity, and ends at
the anus. There are five function under the digestive system, each
function corresponds to each organ of the systems. These are the
following. INGESTION, SECRETION, DIGESTION, ABSORPTION and
EGESTION ( DEFECATION)
Brief anatomy of digestive system
Ingestion is the process of carrying food into the digestive tube through the oral cavity, organs under this process are ( oral cavity, tongue, teeth, salivary glands, esophagus).
Secretion is the process wherein different chemicals and enzymes are being released by the organs to aid in digestion and absorption of nutrients, organs under this function are( stomach, liver, gall bladder and pancreas )
FUNCTIONS OF DIGESTIVE SYSTEM
Digestion is the process wherein the food is being process by the stomach to be absorbed by the body, organ under this process is the stomach.
Absorption is the process of absorbing all the nutrients provided by the food that is being ingested, organs under this process are small intestine { duodenum, jejunum, ileum } and the large intestine { appendix and colon {ascending, transverse and descending}
FUNCTIONS
ILLUSTRATION
ILLUSTRATION
The GI tract is a 23- to 26-foot-long pathway that extends from the mouth through the esophagus, stomach, and intestines to the anus THE FOUR BASIC TUNICS ON THE TUBE ( MUCOSA + SUBMUCOSA + MUSCULARIS + SEROSA)
esophagus -is located in the mediastinum in the thoracic cavity, anterior to the spine and posterior to the trachea and heart(25 cm long)
stomach -is situated in the upper portion of the abdomen to the left of the midline, just under the left diaphragm. It is a distensible pouch with a capacity of approximately 1500mL.
ORGANS AND FUNCTIONS
Stomach- can be divided into four anatomic regions: the cardia (entrance), fundus, body, and pylorus (outlet).
small intestine- is the longest segment of the GI tract, accounting for about two thirds of the total length.
small intestine- is divided into three anatomic parts: the upper part, called the duodenum; the middle part, called the jejunum; and the lower part, called the ileum
ORGANS AND FUNCTIONS
large intestine - consists of an ascending segment on the right side of the abdomen, a transverse segment that extends from right to left in the upper abdomen, and a descending segment on the left side of the abdomen. The terminal portion of the large intestine consists of two parts: the sigmoid colon and the rectum. The rectum is continuous with the anus.
- ORGANS AND FUNCTIONS
The liver is situated in the top part of the abdomen on the right side of the body next to the stomach. It is the largest gland in the body, weighing almost 2 kg. is the major detoxicating organ in the body; it destroys harmful organisms in the blood, produces clotting agents, secretes bile, stores glycogen and metabolises proteins, carbohydrates and fats
ORGANS AND FUNCTIONS
gall bladder- a sac situated underneath the liver, in which bile produced by the liver is stored.
Pancreas- a gland which lies across the back of the body between the kidneys. It has two functions: the first is to secrete the pancreatic juice which goes into the duodenum and digests proteins and carbohydrates; the second function is to produce the hormone insulin which regulates the use of sugar by the body
ORGANS AND FUNCTIONS
Spleen - an organ in the top part of the abdominal cavity behind the stomach and below the diaphragm, which helps to destroy old red blood cells, form lymphocytes and store blood.
Appendix- a small tube attached to the caecum which serves no function but can become infected, causing appendicitis.

Assess the symmetry of contour while standing at the foot of the bed
• If distention is present, measure abdominal girth, by placing tape measure around the umbilicus
Symmetric contour Asymmetric contour (localized protrusions around the umbilicus, inguinal ligaments, or scars) possible hernia or tumor.
ABDOMEN NORMAL FINDINGSDEVIATION FROM
NORMALInspect the abdominal movements associated with respirations, peristalsis, or aortic pulsations
Symmetric movements caused by respirations.
Visible peristalsis in very lean people
Aortic pulsation in thin person at the epigastric area
Limited movement due to pain or disease process.
Visible peristalsis in nonlean clients (with bowel obstruction)
Observe vascular patterns
No visible vascular pattern
Visible venous pattern (dilated veins) associated with liver disease, ascites and venocaval obstruction.
ABDOMEN NORMAL FINDINGS DEVIATION FROM NORMAL
Auscultate the abdomen for bowel sounds, vascular sounds, and peritoneal friction rub.
Audible bowel sounds.
Absence of bruits.
Absence of friction rub.
Absent, hypoactive, or hyperactive bowel sounds.Loud bruit over aortic area (possible aneurysm).Bruit over renal or iliac arteries.
Sites for Auscultating the Abdomen
AUSCULTATING THE ABDOMEN
•Warm the hands and the stethoscope diaphragms.•FOR BOWEL SOUNDS
– Use the flat disc diaphragm. Intestinal sounds are relatively high pitched and best accentuated by the flat disc diaphragm.
– Ask when the client last ate. Shortly after or long after eating, bowel sounds may normally increase. They are loudest when a meal is long overdue. 4-7 hours after a meal, bowel sounds maybe heard continuously over the ileocecal valve area while the digestive system empty through the valve into the large intestine.
– Listen for active bowel sounds ---irregular gurgling noises occurring about every 5 to 20 seconds
– Normal bowel sounds are described as audible, 5-34 bowel sounds per minute
– High pitched, loud, rushing, sounds that occur frequently (e.g. every 3 seconds) also known as BORBORYGMI
– True absence of sounds (none heard in 3 to 5 minutes) indicates cessation of intestinal motility.
AUSCULTATING THE ABDOMEN
– Hypoactive bowel sounds indicate decreased motility and are usualy associated with manipulation of the bowel during surgery, inflammation, paralytic ileus or late obstruction.
– Hyperactive bowel sounds indicate increased intestinal motility and are usually associated with diarrhea, an early bowel obstruction or the use od laxative
•FOR VASCULAR SOUNDS– Use the bell of the stethoscope over the aorta, renal arteries, iliac
arteries, and femoral arteries– Listen for bruits ( blowing sound due to restricted blood flow
through narrowed vessels)
•FOR PERITONEAL FRICTION RUB– Peritoneal friction rub are rough, grating sounds like two pieces of
leather rubbing together.– Friction rubs may be caused by inflammation, infectious or
abnormal growths

Perform light palpation followed by deep palpation of all four quadrants
No tenderness, relaxed abdomen with smooth, consistent tension.
Tenderness maybe present near the xiphoid process, over cecum, and sigmoid colon
Tenderness and hypersensitivity.
Superficial masses.
Localized areas of increased tension
Generalized or localized areas of tenderness
Mobile or fixed masses.
PALPATING THE ABDOMEN
LIGHT PALPATION•To check for muscle tone and tenderness
• Place the hand with fingers together parallel to the area being palpated. Press down 1 to 2 cm. Repeat in ever-widening circles until the area to be examined is covered.
• If patient is excessively ticklish, begin by pressing your hand on top of the client’s hand while pressing lightly. Then slide your hand off the client’s and onto the abdomen to continue the examination.
DEEP PALPATION•To identify abdominal organs and abdominal masses.
•Palpate sensitive areas last.
•With fingers together, approach the area to be examined at a 60 degree angle and use the pads and tips of the fingers of one hand to press in 4 cm.

Assess for Peritoneal inflammation
1. Before palpation, ask the patient to cough and determine where the cough produced pain.
2. Then, palpate gently with one finger to map the tender area.
• Abdominal pain on coughing or with light percussion suggests peritoneal inflammation
ABDOMEN
3.If not, look for rebound tenderness. Press your fingers in firmly and slowly, and then quickly withdraw them.
4.Watch and listen to the patient for signs of pain.
5.Ask the patient (A) to compare which hurt more, the pressing or the letting go, and (B) to show you exactly where it hurt.
Pain induced or increased by quick withdrawal constitutes rebound tenderness. Rebound tenderness suggests
peritoneal inflammation.

ASSESSING ASCITES
Check for a fluid wave.
Ask patient or an assistant to press edges of both hands into the midline of abdomen. Tap one side and feel for a wave transmitted to the other side.
Negative for fluid wave. (No impulse is transmitted when you tap one flank sharply)
An easily palpable impulse suggestsascites.

IN CLASSIC AppendicitiS:
Ask:
Where did the pain begin?
Where is it now?
Ask the patient to cough:”where does it hurt?”Palpate for local tenderness.
Palpate for muscular rigidity.
Near the umbilicus
Right lower quadrant

ABDOMENCheck for Rovsing’s sign and for referred rebound tenderness.
(Press deeply and evenly in the left lower quadrant. Then quickly withdraw your fingers.)
Look for a psoas sign.
Place your hand just above the patient’s right knee and ask the patient to raise that thigh against your hand. Alternatively, ask the patient to turn onto the left side. Then extend the patient’s right legat the hip. Flexion of the leg at the hip makes the psoas muscle contract; extension stretches it.
Pain in the right lower quadrantduring left-sided pressure suggests appendicitis (a positive Rovsing’s sign). So does right lower quadrant pain on quickwithdrawal (referred rebound tenderness).
Increased abdominal pain on eithermaneuver constitutes a positivepsoas sign, suggesting irritation ofthe psoas muscle by an inflamedappendix.
ABDOMEN
Look for an obturator ‘s sign.
Flex the patient’s right thigh at the hip, withthe knee bent, and rotate the leg internally at the hip. This maneuverstretches the internal obturator muscle.
Right hypogastric pain constitutesa positive obturator sign,suggesting irritation of the obturatormuscle by an inflamedappendix.

SPECIAL CONSIDERATIONS
NEWBORN AND INFANT
ABDOMEN Normal Deviation form Normal
Inspect :
A. abdomen with the infant lying supine
B. newborn’s umbilical cord
protuberant
two thick-walled umbilical arteries and one larger but thin-walled umbilical vein, which is usually located at the 12 o’clock position
A single umbilical artery may beassociated with congenital anomalies,but also occurs in normalinfants as an isolated anomaly
ABDOMEN Normal Deviation form Normal
C. Area around the umbilicus for redness or swelling
No redness or swelling Umbilical hernias in infants are dueto a defect in the abdominal wall,and can be up to 6 cm in diameterand quite protuberant when intraabdominalpressure is increased.
ABDOMEN Normal Deviation form Normal
Auscultate for bowel sounds
Percuss an infant’s abdomen as you would for an adult
There is an orchestra of musical tinkling bowel sounds every 10 to 30 seconds.
Note greater tympanitic sounds due to the infant’s propensity toswallow air
An increase in pitch or frequencyof bowel sounds is heard with Gastroenteritisor, rarely, with intestinalObstruction.
A silent, tympanic, distended abdomensuggests peritonitis.
ABDOMEN Normal Deviation form Normal
Palpate the infant’s liver.
Start gently palpating the liver of infants lowin the abdomen, moving upwards with yourfingers
Palpable 1-2 cm below the right costal margin
An enlarged tender liver may be due to congestive heart failure.

EARLY AND LATE CHILDHOOD,AND ADOLESCENCE
Toddlers and young children commonly have protuberant abdomens, most apparent when they are upright. The examination can follow the same order as for adults, except that you may need to open your bag of tricks to distract the child during the examination.

GERIATRICS
Same assessment as the adult
PREGNANT CLIENT
ABDOMEN Normal Deviation form Normal
Inspect any scars or striae, the shape and contour of the abdomen, and theFundal height.
Palpate the abdomen for:
A. Organs or masses.
Purplish striae and linea nigra are normal in pregnancy.
The shape and contour may indicate pregnancy size
The mass of pregnancy is expected.
Scars may confirm the type of priorsurgery, especially cesarean section.
B.Fetal movements.
C. Uterine contractility..
These can usually be felt by the examiner after 24 weeks(and by the mother at 18–20 weeks)
The uterus contracts irregularly after 12 weeks andoften in response to palpation during the third trimester
If movements cannot be felt after 24 weeks, consider error in calculating gestation, fetal death or morbidity, or false pregnancy
Prior to 37 weeks, regular uterinecontractions with or without painor bleeding are abnormal, suggestingpreterm labor.
ABDOMEN
MEASUREMENT OF THE FUNDAL HEIGHT
D. Measure the fundal height with a tape measure if the woman is more than20 weeks’ pregnant
Holding the tape as illustrated and following the midline of the abdomen, measure from the top of the symphysis pubis to the top of the uterine fundus.
After 20 weeks, measurement in centimeters should roughly equal the weeks of gestation.
If fundal height is more than 2 cm higher than expected, consider multiple gestation, a big baby,extra amniotic fluid, or uterine myomata. If it is lower than expected by more than 2 cm,consider missed abortion, transverselie, growth retardation, or false pregnancy.

Auscultate the fetal heart, noting its rate (FHR), location, and rhythm. Use either:
A doptone, with which the FHR is audible after 12 weeks, or
A fetoscope, with which it is audible after 18 weeks
The rate is usually in the 160s during early pregnancy, and then slows to the 120s to 140s near term. After 32 to 34 weeks, the FHR should increase with fetal movement.
Lack of an audible fetal heart mayindicate pregnancy of fewer weeksthan expected, fetal demise, orfalse pregnancy.
FHR that drops noticeablynear term with fetal movementcould indicate poor placentalcirculation.

MODIFIED LEOPOLD’S MANEUVERSThese maneuvers are important adjuncts to palpation of the pregnant
abdomen beginning at 28 weeks of gestation.
They help determine where the
A. fetus is lying in relation to the woman’s back (longitudinal or transverse)
B. what end of the fetus is presenting at the pelvic inlet (head or buttocks),
C. where the fetal back is located, how far the presenting part of the fetus has descended into the maternal pelvis
D.the estimated weight of the fetus.
ABDOMEN
FIRST MANEUVER (UPPER POLE).
Stand at the woman’s side facing her head. Keeping the fingers of both examining hands together, palpate gently with the fingertips to determine what part of the fetus is in the upper pole of the uterine fundus.

Third Maneuver (Lower Pole).
Turn and face the woman’s feet.
Using the flat palmar surfaces of the fingers of both hands and, at the start, touching the fingertips together, palpate the area just above the symphysis pubis. Note whether the hands diverge with downward pressure or stay together. This tells you whether or not the presenting part of the fetus, head or buttocks, is descending into the pelvic inlet.

RADIOLOGIC STUDIES/ IMAGING STUDIES
Imaging studies include x-ray and contrast studies, computed tomography (CT) scans, magnetic resonance imaging (MRI), and scintigraphy (radionuclide imaging).
RADIOLOGIC STUDIES/ IMAGING STUDIES
Upper Gastrointestinal Tract Study
X-rays can delineate the entire GI tract after the introduction of a contrast agent. A radiopaque liquid (eg, barium sulfate) is commonly used. The patient ingests this tasteless, odorless, nongranular, and completely insoluble (hence, not absorbable) powder in the form of a thick or thin aqueous suspension for the purpose of studying the upper GI tract
RADIOLOGIC STUDIES/ IMAGING STUDIES
NURSING INTERVENTIONSThe patient may need to maintain a low-residue
diet for several days before the test. He or she should receive nothing by mouth after
midnight before the test.The physician may prescribe a laxative to clean
out the intestinal tract. Because smoking can stimulate gastric motility,
the nurse discourages the patient from smoking on the morning before the examination.
In addition, the nurse withholds all medications.
RADIOLOGIC STUDIES/ IMAGING STUDIES
Lower Gastrointestinal Tract StudyWhen barium is instilled rectally to
visualize the lower GI tract, the procedure is called a barium enema. The purpose of a barium enema is to detect the presence of polyps, tumors, and other lesions of the large intestine and to demonstrate any abnormal anatomy or malfunction of the bowel
RADIOLOGIC STUDIES/ IMAGING STUDIES
RADIOLOGIC STUDIES/ IMAGING STUDIESComputed TomographyCT provides cross-sectional
images of abdominal organs and structures. Multiple x-ray images are taken from many different angles, digitized in the computer, reconstructed, and then viewed on a computer monitor. Indications for abdominal CT scanning are diseases of the liver, spleen, kidney, pancreas, and pelvic organs.
RADIOLOGIC STUDIES/ IMAGING STUDIES
NURSING INTERVENTIONSThe patient should not eat or drink
for 6 to 8 hours before the test.The practitioner may prescribe an
intravenous or oral contrast agent. Therefore, the nurse should question
the patient about contrast dye allergies.
RADIOLOGIC STUDIES/ IMAGING STUDIES
Magnetic Resonance Imaging
It is a noninvasive technique that uses magnetic fields and radiowaves to produce an image of the area being studied. The use of oral contrast agents to enhance the image has increased the application of this technique for the diagnosis of GI diseases. It is useful in evaluating abdominal soft tissues as well as blood vessels, abscesses, fistulas, neoplasms, and other sources of bleeding.
RADIOLOGIC STUDIES/ IMAGING STUDIES
NURSING INTERVENTIONSThe patient should not eat or drink
for 6 to 8 hours before the test.Before the test, the patient must
remove all jewelry and other metals. It is important to warn patients that
the close-fitting scanners used in many MRI facilities may induce feelings of claustrophobia

Endoscopic procedures used in GI tract assessment include fibroscopy/ esophagogastroduodenoscopy, anoscopy, proctoscopy, sigmoidoscopy, colonoscopy, small-bowel enteroscopy, and endoscopy through ostomy.
ENDOSCOPIC PROCEDURES
Upper Gastrointestinal Fibroscopy/EsophagogastroduodenoscopyFIBROSCOPY of the upper GI tract allows direct visualizationof the esophageal, gastric, and duodenal mucosa through alighted endoscope.ESOPHAGOGASTRODUODENOSCOPY (EGD), is especially
valuablewhen esophageal, gastric, or duodenal abnormalities or
inflammatory,neoplastic, or infectious processes are suspected.This procedure also can be used to evaluate esophageal and
gastricmotility and to collect secretions and tissue specimens for furtheranalysis.
