Study Notes
Acute Abdominal Pain
- Abdominal pain is one of the most common reasons adults visit the emergency department.
- When evaluating abdominal pain, it's crucial to understand the patient's history, including prior episodes, diagnostics, treatments, and any potential exposures to toxins.
- A thorough physical examination should include inspection for distension, scars, and hernias.
- Palpation for tenderness, masses, guarding, and rebound tenderness should be performed.
- A pelvic and rectal exam may be indicated depending on the patient's presenting symptoms.
- Auscultate for bowel sounds.
- Laboratory tests like CBC, LFT, electrolytes, lipase, urinalysis, and B-HCG should be ordered.
-
Imaging:
- Abdominal/pelvic ultrasound can be used to evaluate the gallbladder, liver, and gynecological issues.
- A CT scan is helpful for diagnosing bowel obstruction, perforation, and vascular issues.
- X-ray can detect free air (pneumoperitoneum) and bowel obstruction.
Acute Abdominal Pain Treatment
- Analgesia such as opioid like morphine can be used to provide pain relief.
- Anti-emetics like ondansetron can help manage nausea and vomiting.
- Intravenous fluids are essential for rehydration.
- Antibiotics may be necessary in cases of peritonitis, diverticulitis, or cholecystitis.
Abdominal Pain Causes & Treatment
- Appendicitis: Requires surgical intervention.
- Bowel obstruction: Treated with nasogastric decompression.
- Perforated ulcer: Requires surgical intervention.
- Pancreatitis: Requires supportive care.
- Ectopic pregnancy: Considered a gynecological emergency requiring appropriate management.
Diarrhea
- Acute diarrhea involves an increase in the water content of stool, leading to an increased frequency of bowel movements.
- Diarrhea can be classified as acute (lasting less than 14 days) or chronic (lasting more than 2 weeks).
- Causes of diarrhea include infection, medications, and other medical conditions.
Diarrheal Disease
- When evaluating diarrhea, it's important to assess the duration, frequency, consistency, associated symptoms (e.g., fever, pain, weight loss), recent travel history, food intake, and antibiotic use.
- Pre-existing medical conditions such as Irritable Bowel Syndrome (IBS) and Celiac disease should be considered.
- Examination for signs of dehydration, distension, and tenderness is crucial.
- Stool analysis and culture are important for further investigation.
Diarrheal Disease Treatment
- Fluid and electrolyte replacement: Oral rehydration solutions (ORS) are recommended for mild to moderate dehydration.
- Intravenous fluids like Ringer's lactate or normal saline are necessary for severe or continuous fluid losses, or when patients cannot tolerate oral intake.
- Antibiotics: May be indicated in cases of severe bacterial infection or Clostridium difficile infection.
- Antimotility agents: Loperamide can be helpful, but it's not recommended for patients with bloody diarrhea or suspected inflammatory diarrhea.
- Probiotics: May be beneficial when used alongside rehydration therapy.
Common Causes of Diarrhea
- Viral gastroenteritis is the most common cause of diarrhea.
- Bacterial infections: Salmonella, Shigella, E. coli, Campylobacter, and Vibrio cholera are common culprits.
- Parasitic infections: Giardia lamblia and Entamoeba histolytica are examples of parasitic infections causing diarrhea.
- Antibiotic-associated diarrhea: often caused by Clostridium difficile.
Upper Gastrointestinal (GI) Bleeding
- Upper GI bleeding refers to bleeding originating from the esophagus, stomach, or duodenum, which is proximal to the ligament of Treitz.
- It is a potentially life-threatening condition that requires prompt evaluation and management.
- The primary goals of management include stabilizing the patient, identifying the source of bleeding, and treating the underlying cause.
Causes of Upper GI Bleeding
- Peptic ulcers: The most common cause, including gastric and duodenal ulcers.
- Esophageal varices: Common in patients with liver cirrhosis and portal hypertension.
- Mallory-Weiss syndrome: Mucosal tear at the gastroesophageal junction due to forceful vomiting.
- Malignancy: Cancer within the upper GI tract.
Initial Stabilization of Upper GI Bleeding
-
ABCD Approach:
- Airway: Ensure patency, especially in cases of massive bleeding or altered mental status. Intubation may be necessary for airway protection.
- Breathing: Administer oxygen.
- Circulation: Establish intravenous access with at least two large-bore (18G) cannulae. Initiate intravenous fluid resuscitation with normal saline or lactated Ringer's solution. Consider blood transfusion if hemoglobin levels are critically low.
- Close monitoring: Admit the patient to a monitored bed and monitor vital signs closely.
