Mechanical p. 318

Abdominal organs, with the exception of the aorta, are not sensitive to mechanical stimuli such as cutting or tearing Abdominal organs and membranes ARE sensitive to stretching and distention which activate nerve endings in both hollow and solid structures. Capsules surrounding organs like the liver, spleen, and gallbladder contain pain fibers that are stimulated by stretching if these organs swell.

Clinical insight p. 318

Abdominal pain in a pregnant patient, other than the pain caused by contractions, is usually considered serious, until proven otherwise

Clinical insight p. 319

The description of pain is important for determining hollow versus solid organ cause, or aortic cuse versus other causes of adbominal pain, as is the progression of the pain (e.g. intermittent progressing to steady or generalized to specific)

Important Note p. 334

The focus of assessment is not to discriminate between possible causes of abdominal pain. Rather, the focus is to determine the probability of a life threat.

Table 8-1 Abdominal Pain from Extraabdominal causes: Signs and Symptoms p. 321

The following 7 flash cards are the signs and symptoms and what extraabdominal causes these indicate

Left Hypochondriac Region

The left hypochondriac region contains the pancreas and the spleen with referred pain from the left pleural space pancreas and spleen

More about pancrease secretions

The pancreas secretes digestive enzymes and controls blood sugare levels through the iproduction of insulin.

Important Note p. 333

The patient who has complained of abdominal pain and then progresses to unresponsiveness must be considered to have a threat to life until proven otherwise

Clinical Insight p. 327

The presence of postural hypotension in the prescence of an abdominal complaint (which may NOT be described as "pai") is highly suggestive of acute blood loss from a ruptured organ such as the liver oir spleen, a tubal pregnancy or a leaking aortic aneurysm.

Right Iliac Region

The right iliac region contains the ascending colon and the appendix and in the female a right ovary and fallopian tube. Appendix, Overies and Fallopian Tues

peritoneum p. 317

The serous membrane that lines the abdominopelvic cavity and helps subdivide tha abdomen vertically : The parietal peritoneum covers the outer wall The visceral peritoneum covers internal organs.

Umbilical and Hypogastric Regions

The umbilical region contains the small intestine, large intestine, and aorta with referred pain from the appendix. The hypogastric region contains the bladder and aorta with referred pain from intestinal obstruction. Together these regions are often referred to as the central abdomen with several disease states manifesting pain in this area. Small Intestine, Large Intestine, Aorta, Pain referred to the umbilical and hypogastric regions

Peritoneum p. 318

Traction, or tension, on the peritoneum caused by adhesions, distention of the common bile duct or forceful peristalsis resulting form intestinal obstructions generally causes pain. Exception: In pregnancy by the third trimester, the peritoneum is no longer sensitive to stretching; therefore, the response to stimuli that would normally produce pain is blunted. Conditions: cholelithiasis (gallstones) and appendicitis in pregnant women have the potential to be serious.(They may go a long time and feel no pain)

aneurysm p. 330

aneurysm is a weakened dilated area of the wall of a vessel

peritoneal space p. 317

anterior portion of the abdomen

peristalsis p. 317

rhythmic contractions that move substances through hollow organs or tubes

Viscera p. 317

the internal organs

Quadrants and regions are useful because...

there is a known relationship between superficial anatomical landmarks and the locations of underlying organs.

referred pain p. 319

visceral pain felt at some distance from a diseased or affected organ (e.g. pain from an ovarian cyst felt in the shoulder or neck). This occurs when the brain misinterprets the pain as originating from a cutanious nerve that innervates an area that is in fact at a site other than the affected organ

Parietal pain p. 319

~Arises from the parietal peritoneum. ~More localized and intense than visceral pain ~Never fibers in the parietal peritoneum travel with associated peripheral nerves to the spinal cord and sensation of pain most frequently corresponds to skin dermatomes T6 and L1 that are innervated by those segments of the spinal cord. ~Parietal pain is localized to one side or the other because at any particular point the parietal peritoneum is unnervated from only one side of the nervous system.

Parietal Pain described p. 319

~Sharp and constant. ~Patients often feel beter in fetal position with knees drawn up. ~This relaxes the parietal peritoneum and reduces pain. ~Any activity that moves the peritoneum like coughing, deep breathing, or lying flat with legs outstretched will produce pain. ~The characteristics of parietal pain are sometimes seen as signs of peritoneal irritation and frequently occurs after visceral pain.

Differential Diagnosis in the field p. 322

Only occasionally will a disease process exhibit such classic signs and symptoms that a specific diagnosis will be mistakable. Most cases require a careful history and complete physical may narrow the problem to suspected : bleeding, obstruction, sepsis or irritant isolated to a particular area of organ type. IMPORTANT NOTE ****These determinations , along with mental status , cardiovascular status, and respiratory status, that will determine probability of immediate, potential or no life threat...and if patient is critical, unstable, potentially unstabel, or table (CUPS)

Right and Left Lumbar Regions

Organs in thiese regions include the kidneys and their associated ureters. Kidneys and Ureters

Left Iliac Region

Organs in this region include the descending colon (large intestine) and in the female, the left ovary and fallopian tube) Most of the pain from diseases affecting the large intestine is referred to umbilical or hypogastric region. However, certain specific conditions may localize pain in either the right or the left iliac region, such as diverticulitis which localizes pain in the left ilac region.

Epigastric Region

Organs in this region include the stomach and pancreas with refered pain from the heart and appendix Stomach, Pancreas, Pain referred to the Epigastric Region from the heart(which is on the dome of the region) and Vagus nerve bundle

To help describe the location of findings: Quadrants (4) Figure 8-2 (a) p. 317

The abdominal area is divided into 4 quadrants: 1. the right upper quadrant (RUQ), 2. the left upper quadrant (LUQ), 3. the right lower quadrant (RLQ) and 4. the left lower quadrant (LLQ) (Figure 8-2a p. 317) These terms and their abbreviation are commonly used in clinical discussions.

Clinical Insight p. 333

The action of being up and walking around suggests that a perfusing blood pressure is present

Anatomy, Physiology, and Pathophysiology p. 315

The basis for understanding the characteristics of abdominal pain is in the anatomy, physiology, and pathophysiology Abdominal organs are suspended within the abdominal cavity (Fig. 8-1) p. 316 The abdominal cavity has two essential functions: 1. protection of organs from the accidental bumping and jostling that occurs during daily activity such as walking, jumping, running 2. Permitting organs to expand and contract without distrupting surrounding tissues or organ functions

Location and characteristics indicate possible origin All individuals react differently according to factors Age - Infants and children may be unable to localize their discomfort and they have diseases not seen in adults Tolerance - Obese or elderly patients tend to tolerate pain better Preexisting conditions - Neuropathy such as that which occurs with diabetes can mask intraabdominal pathology, as can alcohol and certain medications escpecially steroids. Perception - What is perceived as severe pain to one person may not be to another Mental State - Hysteria tends to exaggerate pain, and emotional pain tends to worsen physical pain

The degree of threat to life p. 322

i.e., if the condition is an immediate life threat, a potential life threat, or ot a life threat

Extraabdominal Problems that may refer pain to abdomen p. 320-322 AMI

Peritonitis Early appendicitis Bowel obstruction Intestinal Ischemia Aortic aneurysm Gastroenteritis Pancreatitis Diabetic ketoacidosis Sickle cell crisis

Summary of Treatment p. 342 IV fluids PART 2

**Note The drug of choice in the field is dopamine. The dosage is based on μg/kg/min with 5 - 10 μg/kg/min as a usual starting dose, titrated to systolic prssure Sepsis may also affect alveolar and capillary wall permeability, causing pulmonary edema. Thus, positive-pressure ventilations along with fluids are often necessary. Positive pressure ventilations along with fluids are often necessary. Dehydration with third spacing of fluid is a significant finding with sepsis.

How to determine if the pain in the abdomen radiates from another site p. 336-8

1. Inspection of abdomen(look for distention/absence of distention) and inspection of color. 2. Auscultation Commonly done in hospital setting, is not recommended for short transport times in the field because: *not quiet enough for the amount of time it takes *Treatment does not depend on this Ausculation of chest is recommended. 3. Palpation of abdomen if it does not increase comfort of patient (first do no harm). Start far from pain. Watch for tenderness. REBOUND palpation is not recommended.

Physical exam should accomplish 3 things p. 335-6

1. Is the patient critical/threat to life or potentially unstable 2. Determine a high or low probability for involvement of a specific organ or the presence of a specific condition like bleeding, infection or obstruction 3. Determine what treatment is appropriate

Table 8-3 Pain Referred to Abdominal Regions p. 324 Pain in these areas 1. Right hypochondriac Region 2. Epigastric region 3. Left hypochondriac region 4. Umbilical and hypogastric regions

Summary of Treatment p. 340 The pneumatic antishock garment (PASG)

Suggested for treating abdominal bleeding, especially abdominal aortic aneurysm. The garment helps stabilize the aneurysm by exerting circumferential pressure. NOTE ***The use of this device is highly controversial

Acute Abdominal Pain Chapter 8 p. 314-343 Topics covered: When chief complaint is abdominal Pain, Anatomy, physiology and pathophysiology, differential diagnosis, assessment, and treatment

A common Chief complaint Presenting symptom for a number of diseases Always a symptom of intraabdominal pathology Treatment is primarily aimed at supporting vital functions, making the patient as comfortable as possible and transporting him to the hospital

Differential Diagnosis p. 322

A differential diagnosis determined in the field takes on a far different meaning that the differential diagnosis determined in a hospital setting. In the field differential diagnosis for abdominal pain is frequently limited to determining two things: 1. the degree of threat to life 2. A suggested organ type

More Stomach Description p. 325 Gastric glands secrete hydrochloric acid, enzymes, and intrinsic factor ) a substance that makes possible the absorption of vitamin B12

A muscular, sac-like organ , shaped like an expanded J. It is located primarily in the epigastric region of the abdominopelvic cavity. The outer surface is covered by the peritoneum, which is continuous with a pair of mesenteries, the greater omentum ( a site for fat deposit that protects the abdominal organs), and the lesser omentum. The stomach is lined with mucous cells that secrete mucus to protect the lining from acids, enqymes and abrasive materials it contains

Parietal Pain examples: p. 319

Appendix - at first it may be described as intermittent and dull, arising from the umbilical region. (This is visceral pain from distention of the appendix) As time goes on and bacteria penetrate the wall of the appendix, pain more closely resembles parietal pai. It becomes sharper, constant and localized to the righ lower quadrant with the patient more comfortable if knees are drawn up. This localization of pain reflects dermatome distribution.

Signs and symptoms of Abdominal Pain Associated with and indicated extraabdominal causes Table 8-1 p. 321 Spleen - normally cannot be palpated due to posterior location

Enlarged or irritation: Steady, dull pain. May radiate to left neck and shoulder. Ruptured: Sharp, intense pain, lets up, then recurs, increases in intensity, radiates to left neck and shoulder; syncope, postural hypotension.

Clinical Insight p. 326

Because injury to alveolar membranes of the lungs (usually on the left side) may occur with pancreatic disease, lung sounds may include wheezing or crackles

Clinical Insight p. 331

Because of its ability to wriggle and twist, an inflamed appendix may be located more to the posterior or more to the left than normal. This may cause atypical description of appendicitis,

Special Note p. 340

Because the abdomen tends to be a site for referred pain, the ECG should be monitored in older patients and diabetic patients. Look for associated weakness and or breathlessness especially on exertion and initiate ECG monitoring. Diabetic patients should also have a blood sugar evaluation. If pain in abdomen took for other signs of diabetic ketoacidosis like rapid respiration with an acetone or fruity odor, history of polyuria, tachycardia and poor skin turgor. Pulse oximetry can be useful to assess respiratory function; however it does not serve as a substitute for good respiratory assessment and is inaccurate in shock states.

Signs and symptoms of Abdominal Pain Associated with and indicated extraabdominal causes Table 8-1 p. 321 Small Intestine and Large intestine - Part 2

Bowel Obstruction: Begins with intermittent, crampy or colicky pain. If unrelieved, distention and peritoneal irritation with increasingly intense, steady, poorly localized pain. Patient may lie in fetal position. Shallow respirations; pain worsened by coughing or deep breathing. Inflamed pockets in colon wall (dirverticulitis): Dull pain tenderness on palpation. If perforated spillage of contents into peritoneal space,k causing steady, sharp pain and signs of peritoneal irritation. Early pain is poorly localized and referred to hypogastric region; later pain becomes localized, commonly to lower left quadrant. Diarrhea, fever, bleeding (from occult to massive) may be present

Spinal or CNS disease p. 322

Can produce pain referred to the abdomen. The most common cause is radiculitis (inflammation of spinal nerve roots), of which herpes zoster, or shingles is the best-known example. This pain is usually chronic rather than acute. In the case of shingles pain may precede the appearance of the ras.

QUALITY P. 335

Can you Describe the Pain

Assessment of abdominal pain p. 322

If associated signs and symptoms indicate a possible extraabdominal cause of abdominal pain, ask questions and look for environmental clues to determine whether the patient has any known or suspected disease or condition. Previous history is usually very important. Although it may be impossible to know exactly the origin of the abdominal pain, a through assessment, including history and physical exam, will always be the best basis for treatment decisions.

Summary of Treatment p. 340 IV treatment

Depending on the problem, IV access may be appropriate, but do not delay transport to get a line. IV access can be obtained en route. If internal bleeding is a high probability ensure that administration of IV fluids does not cause disruption of clot formation.(This can happen when systolic pressure is above 100) In the case of an abdominal aortic aneurysm, high systolic pressures may increase the likelihood of complete rupture. In this case suggestions are to keep systolic pressure between 70-100 mmHg using mental status as a guide.

Ectopic Pregnancy p. 332

Ectopic pregnancy is a pregnancy in which the ovum is implanted in an area outside the uterus, usually in a fallopian (tubal pregnancy).

pain in hollow organs p. 319

Edema and vascular congestion from inflammation may also cause an obstruction or irritation of the lining of membranes lining the walls. Obstruction or irritation of the lining of hollow organs frequently stimulates contractions and peristalsis. The resulting pain is often described as crampy or colicky. In gastroenteritis, increased peristalsis of the small or large intestine ay also trigger diarrhea. If obstruction is not relieved, intermittent pain may become constant.

Summary of Palliation of Pain p. 342

May systems are using pharmacologic pain relief methods, such as nitrous oxide, morphine, or fentayl. if pain is present. Midazolam (Versed) does not relieve pain but does relieve anxiety. Promoting patient comfort is important BUT use of pain relief measures mandates complete assessments and thorough study of the pharmacologic agens used. USE MEDICAL DIRECTION AND LOCAL PROTOCOL.

Focused History and physical Exam is to focus to determine the probabilities of an immediate threat to life and to clarify the organ system that is probably involved. Use mnemonics like OPQRST to get information about pain p. 334-335

Signs and symptoms of Abdominal Pain Associated with and indicated extraabdominal causes Table 8-1 p. 321 Pancreas - a tadpole shape When large quantities of digestive enzymes pool within the pancreas, the pancreatic secretions begin, literally to digest the pancreas itself.

Pancreatic inflammation (pancreatis): Usually causes peritoneal irritation resulting in sudden, constant, severe pain. Patient feels more comfortable lying still with knees drawn up. Patients look toxic and are extremely ill. Because the pancreas lies in both the peritoneal and the retroperitoneal spaces, pancreatic exudate-containing toxins and activated pancreatic enzymes permeate the retroperitoneum, often including the anterior or pertoneal cavity. This induces a chemical burn and increase in permeability of blood vessels and leads to third spacing, hypovolemia and shock.

Usually felt near the midline in the epigastrium or umbilical region. Visceral pain is poorly localized and is dull rather than sharp. It is diffuse and vague because nerve endings are sparse and multisegmented in abdominal organs. IN hollow organs:Described as crampy or colicky and tend to be dull and intermittent. In solid organs: dull and constant

ONSET p. 334

Was it sudden? What were you doing when it started? Has this pain happened before?

Signs and symptoms of Abdominal Pain Associated with and indicated extraabdominal causes Table 8-1 p. 321 Aorta - Ordinarily, the aorta cannot be palpated; however, sometimes the aneurysm can be felt as a pulsating mass.

Weakened, dilated area (aneurysm): May present with syncope with or without pain. Usually presents with steady, deep boring or tearing visceral pain in lower back, radiating to lower abdomen or vice versa. Pain may also radiate to one flank or the other or down either leg or both legs. May be felt on palpation as a pulsating mass and may be tender to palpation. May leak, then rupture, causing severe pain. A serious threat to life.

PALLIATION/PROVOCATION P. 334

What makes the pain better? What makes the pain worse?

Associated Symptoms or Pattern of Onset p. 335

What other problems or complaints have you also noticed? This question may help narrow the problems. When vomiting precedes pain and followed by diarrhea, gastroenteritis is probable. Pallor, sweating, fainting are rough guides to severity of pathological process. Presence of of shock is an ABSOLUTE indicator of severity. It is a life threat.

Determining if the condition is potentially life threatening p. 315

You can establish this by: careful history focused physical exam limited number of diagnostic tests can be done in the field (e.g. blood sugar values, 12-lead ECG, and orthostatic blood pressure checks)

Table 8-4 Abdominal Pain: Clues to the Severity of Patient's Condition These are characteristics of abdominal pain and associated signs/symptoms and indicate a serious condition and potential threat to life --a critical, unstable or potentially unstable condition --warranting expeditious care and trans port:

^Sudden onset (potentially unstable) ^Severe pain (may be described as "knife-like") (potentially unstable) ^Pulsating mass present (unstable or potentially unstable) ^Fainting; loss of consciousness (critical or unstable) ^Any signs of shock or internal blood loss (e.g. diminished mental status; pale, moist skin; mottled skin; rapid, shallow respirations; rapid pulse; falling blood pressure) (critical or unstable) ^Orthostatic hypotension or positive tilt test (critical or unstable)

Referred pain p. 319-320

~Visceral pain felt at some distance from a diseased or affected organ ~The site is referred pain and usually well localized and felt in skin or deeper tissues that share a central afferent nerve pathway (toward the spinal cord) with affected organs. ~Usually develops as intensity increases ~EX: Gallbladder pain is referred to a scapula or to the back between the scapulae. It may begin as a crampy discomfort in the right upper quadrant and as inflammation worsens, progress to a sharp localized referred pain to the right scapula or between the shoulder blades. See Fig. 8-4 for common areas of referred pain for given organs
