Study Notes
Acute Gastrointestinal Hemorrhage
- A potentially life-threatening emergency
- Common complication of critical illness
- Can occur from upper or lower gastrointestinal tract
Upper Gastrointestinal Tract Bleeding
- Peptic ulcer disease: Most common cause
- Often results from breakdown of gastromucosal lining
- Factors:
- Chronic ingestion of NSAIDs, aspirin, and alcohol
- Presence of Helicobacter pylori (H. pylori) infection
- Stress-related erosive syndrome:
- Stress ulcer
- Stress gastritis
Lower Gastrointestinal Tract Bleeding
- Diverticulosis: Outpouching of the bowel wall
- Inflammatory bowel disease
- Crohn's disease
- Ulcerative colitis: causes friability of the bowel wall
- Trauma
- Neoplasm
- Infectious colitis
- Radiation colitis
- Angiodysplasia
- Ischemia
- Aortoenteric fistula
- Hemorrhoids: Presence of varicosities in the rectal and anal vein
Pathophysiology
- Characterized by acute, massive bleeding
- Results in hypovolemic shock, activation of the shock response, and potential development of multiple organ dysfunction syndrome if left untreated
Clinical Classification of Hemorrhage
- Classified into four classes based on blood loss percentage and clinical signs/symptoms
Hallmarks of Gastrointestinal Hemorrhage
- Hematemesis: Vomiting of blood, can be bright red or coffee ground/brownish
- Hematochezia: Presence of bright red stool
- Melena: Black tarry or dark red stool
Priorities in Management
- Airway protection
- Fluid resuscitation
- Correction of co-morbid conditions (e.g., coagulopathy)
- Therapeutic procedures: control or stop bleeding and diagnostic procedures to determine the cause
Stabilization: Initial Treatment Priority
- Initiate fluid resuscitation
- Intravenous infusions of crystalloids, blood, and blood products
- Administer Vitamin K for coagulopathy
- Vasopressor medications: dopamine, epinephrine, or norepinephrine
- Supplemental oxygen therapy
- Monitor hemodynamic parameters
- Insert large nasogastric tube
Controlling the Bleeding
- Peptic Ulcer Disease (PUD)
- Endoscopic injection therapy with hemostatic clips
- Endoscopic thermal therapy
- Intra-arterial infusion of vasopressin or embolizing agent
- Stress-Related Mucosal Disease
- Intra-arterial infusion of vasopressin and intraarterial embolization
- Esophagogastric Varices: Control may be achieved through pharmacologic agents and endoscopic therapies
- Intravenous administration of vasopressin, somatostatin, and octreotide
- Endoscopic treatments: endoscopic injection sclerotherapy (EIS) and endoscopic variceal ligation (EVL)
- If EIS and EVL fail: Transjugular Intrahepatic Portosystemic Shunting (TIPS)
- Surgical Intervention: For patients unresponsive to conservative medical management
- PUD: Vagotomy and pyloroplasty
- Esophageal Varices: Decompression procedures such as portacaval shunt procedure
Key Points:
- H. pylori is a primary factor in the development of peptic ulcer disease.
- Stress-related erosive syndrome is a major cause of upper GI hemorrhage.
- Fluid resuscitation is essential for stabilizing patients with GI hemorrhage.
- Endoscopic therapies are the preferred treatment for controlling bleeding from PUD and esophageal varices.
- Vasopressin is a potent vasoconstrictor used in managing upper GI hemorrhage, but it can have significant side effects.
- TIPS is a surgical procedure used for severe cases of variceal hemorrhage.
