Git Bleeding Flashcards
(7 cards)
Risk factors
A- Medical Conditions
1_Peptic ulcer disease (most common cause)
2-Esophageal varices (due to portal hypertension)
3-Gastritis or duodenitis
4-Gastroesophageal reflux disease (GERD)
5-Mallory-Weiss tears (mucosal laceration due to severe vomiting)
6-Gastric or esophageal cancer
7-Dieulafoy lesion (abnormal artery in the stomach)
8-Angiodysplasia
Risk factors
B- Medications
1-NSAIDs (e.g., ibuprofen, aspirin) – damage the gastric mucosa
2-Anticoagulants (e.g., warfarin, DOACs) – increase bleeding risk
3-Corticosteroids – especially when combined with NSAIDs
4-SSRIs – associated with increased bleeding risk
Risk factors
B-Lifestyle Factors
1-Alcohol use – causes gastritis and varices
2-Smoking – impairs mucosal healing
3-Chronic vomiting – can lead to Mallory-Weiss tears
4-stress
4-Diet
Risk factors
D-Infections
Helicobacter pylori infection – strongly associated with peptic ulcers
Risk factors
E- Systemic Factors
1-Liver disease – leads to varices and coagulopathy
Coagulopathies – congenital or acquired
2-Renal failure – associated with uremic gastritis
Management
- Endoscopic Management
Performed after initial stabilization (typically within 24 hours):
Diagnostic Endoscopy
Identifies source of bleeding (Forrest classification can help guide therapy).
Therapeutic Endoscopy
Indicated for active bleeding or high-risk stigmata (Forrest Ia–IIb):
Injection therapy (e.g., epinephrine)
Thermal coagulation (e.g., heater probe, bipolar coagulation)
Mechanical therapy (e.g., hemoclips)
Often combination therapy (e.g., epinephrine + clips) is most effective.
Management
Medical Management
1-Initial Stabilization
Airway, Breathing, Circulation (ABC) – resuscitate as needed.
IV fluids – isotonic saline or Ringer’s lactate.
Blood transfusion – if hemoglobin <7 g/dL (or <9 g/dL in high-risk patients).
Correct coagulopathies – vitamin K, fresh frozen plasma, platelets if indicated.
Pharmacologic Therapy
Proton Pump Inhibitors (PPIs):
High-dose IV (e.g., omeprazole 80 mg bolus, then 8 mg/hr infusion for 72 hrs).
Reduces rebleeding risk by stabilizing clot in low-acid environment.
Eradicate H. pylori (if present) – with triple or quadruple therapy.
Discontinue NSAIDs and anticoagulants if possible.
