Q

This type of pain is described as tension, stretching, ischemia stimulation of specific pain fibers. It is a dull, aching, diffuse, vague (poorly localized) pain felt at the midline in the epigastric, periumbilical or suprapubic areas. Utilizes C type fibers.

26
This term represents a rapid onset of severe symptoms that may indicate a life-threatening intra-abdominal pathology.
Acute Abdomen
27
Signs and Symptoms of Acute Abdomen:
- Fever - Protracted Vomiting - Syncope - Pre-syncope - GI Blood Loss
28
T/F: In acute abdomen situations, pain is always a feature.
False, not always! Pain-free is more likely in the elderly, in children and in the third trimester of pregnancy.
29
Management of Acute Abdomen
Carefully assess before managing! Pay close attention to the Signs and Symptoms that may indicate a need to investigate the situation further in the hospital.
30
T/F: Clinical Scenarios can change rapidly in a patient with an acute abdomen.
True!! Conclusions previously reached by yourself or colleagues may need to be revised as events evolve.
31
Pathophysiologic Mechanisms of Abdominal Pain
1. Obstruction 2. Peritoneal Irritation 3. Vascular Insufficiency 4. Mucosal Ulcertion 5. Altered Motility 6. Metabolic Disturbances 7. Nerve Injury 8. Muscle Wall Dz 9. Referred Pain 10. Psychogenic Causes
32
Locations of GI/GU Obstruction that causes Acute Abdominal Pain:
1. Gastric Outlet (stricture/CA) 2. Small Bowel – pain of SB>LB (the jejunum is probably the most painful site since there is no “natural” way to decompress the region 3. Large Bowel (stricture/CA) 4. Biliary Tree (stones/strictures/CA) - - Cystic duct – biliary colic - - Common Bile Duct - -- Ampulla of Vater 5. Urinary Tract (stones/strictures/CA) - - Pyelonephritis - - Kidney/ureteral stone
33
Causes of Peritoneal Inflammation that causes Acute Abdominal Pain:
1. Infection 2. Chemical irritation from perforation of a viscus (blood, bile, gastric acid) 3. Systemic inflammatory process 4. Spread from a focal inflammatory process
34
Causes of Vascular Insufficiency that causes Acute Abdominal Pain:
1. Embolization (blood/lipid/atherosclerotic plaque) - - PE - - AF 2. Atherosclerotic Narrowing (Ischemic Bowel) - - Acute Arterial Insufficiency or Acute Mesenteric Ischemia - - Chronic Mesenteric Ischemia - -Ischemia Colitis 3. AAA and Aortic Dissection
35
Causes of Mucosal Ulceration that causes Acute Abdominal Pain:
1. PUD -- Epigastric, gnawing, burning, can fistulize to pancreas in severe cases and become catastrophic. 2. Gastric cancer 3. IBD/gastroenteritis 4. Celiac Sprue -- Genetically predisposed, inappropriate T-cell response to ingested gluten – episodic bloating, diarrhea, flatulence, weight loss (Malabsorption).
36
Causes of Altered Motility that causes Acute Abdominal Pain:
1. Malabsorption/Maldigestion 2. IBD (UC or Crohn’s) 3. IBS/IGS Irritable Bowel or Gut Syndrome) 4. Diverticular Disease (and Diverticulitis)
37
Causes of Metabolic Disturbances that causes Acute Abdominal Pain:
1. Diabetic Ketoacidosis 2. Porphyria 3. Lead Poisoning (affects hemoglobin synthesis)
38
Causes of Nerve Injury that causes Acute Abdominal Pain:
1. Intra-abdominal (Pancreatic Cancer vs. Pancreatitis) | 2. Extra-abdominal (Herpes Zoster)
39
Causes of Muscle Wall Dz that causes Acute Abdominal Pain:
1. Trauma 2. Myositis or Chondritis (inflammation of muscle or intercostal cartilage at point of traumatic contact) 3. Fibromyalgia?
40
Causes of Referred Pain that causes Acute Abdominal Pain:
1. Chest Sources (Lower Lobe PNA or Inferior MI) | 2. Pelvic Sources (ovarian masses)
41
Causes of Acute Abdominal Pain caused by Psychogenic Issues:
1. Somatization 2. Depression 3. Anxiety
42
Causes of Obstruction that causes Acute Abdominal Pain:
1. Adhesions 2. Hernia 3. Volvulus 4. Paralytic Ileus 5. Intussusception 6. Fecal Impaction 7. Carcinoma 8. Mesenteric Infarction 9. Regional Ileitis 10. Malrotation THINK SURGICAL EMERGENCY!!!!!!

51
Red Flags when seeing Abdominal Pain (SEVERE cases)
- Hypotension - Confusion or impaired consciousness - Signs of shock - Systemically unwell, septic-looking - Signs of dehydration - Rigid or distended abdomen - Known pregnancy with severe pain - Patient lying very still or writhing in pain (parietal pain) - Absent or altered bowel sounds - Associated testicular pathology - Marked involuntary guarding, rebound tenderness - Exquisite tenderness to percussion - History of hematemesis, melena or evidence of blood on rectal examination
