Emergency Department Management of Acute GI Bleeding
Immediate Resuscitation (First 15 Minutes)
For any patient presenting with GI bleeding and hemodynamic instability (hypotension, tachycardia), immediately secure two large-bore IV lines (16-gauge or larger in antecubital fossae), initiate crystalloid resuscitation, and protect the airway if massive hemorrhage or altered mental status is present. 1, 2
Airway Management
- Perform endotracheal intubation immediately if: 3, 1
- Massive ongoing hematemesis
- Hepatic encephalopathy (Grade 3-4)
- Inability to maintain oxygen saturation >90%
- Aspiration pneumonia or risk of aspiration
Volume Resuscitation
- Restore circulatory volume with crystalloids (normal saline or lactated Ringer's) targeting mean arterial pressure >65 mmHg, but avoid aggressive over-resuscitation. 3, 1
- Use a restrictive transfusion strategy: transfuse packed red blood cells only when hemoglobin drops below 7 g/dL, maintaining a target of 7-9 g/dL. 3, 1, 2
- Exception: Consider higher threshold (hemoglobin 8-9 g/dL) in patients with active cardiovascular disease 3
- Avoid liberal transfusion—it increases portal pressure, promotes rebleeding, and worsens mortality in cirrhotic patients. 3, 1
Blood Product Management
- Cross-match 6 units of packed red blood cells immediately. 3
- Do NOT routinely transfuse fresh frozen plasma, platelets, or cryoprecipitate unless massive hemorrhage with documented coagulopathy (fibrinogen <120 mg/dL, platelets <50,000, INR significantly elevated with active bleeding). 3, 1
Immediate Pharmacological Therapy (Before Endoscopy)
For Suspected Variceal Bleeding (Any Patient with Known/Suspected Cirrhosis)
Start vasoactive drug therapy immediately upon suspicion of variceal bleeding—do not wait for endoscopic confirmation. 3, 1, 2, 4
Choose ONE of the following: 3, 1
- Octreotide: 50 mcg IV bolus, then 50 mcg/hour continuous infusion 1
- Somatostatin: 250 mcg IV bolus, then 250-500 mcg/hour continuous infusion 1
- Terlipressin: 2 mg IV every 4 hours for first 48 hours, then 1 mg IV every 4 hours 1
Continue vasoactive therapy for 3-5 days after endoscopic confirmation to prevent early rebleeding. 1, 2
Antibiotic Prophylaxis (Critical for All Cirrhotic Patients)
Administer antibiotic prophylaxis immediately—this reduces bacterial infections by >50%, decreases rebleeding, and improves survival. 3, 1, 2
- Ceftriaxone 1 g IV daily for up to 7 days (preferred in decompensated cirrhosis [Child B/C], patients on quinolone prophylaxis, or settings with quinolone resistance)
Alternative (if ceftriaxone unavailable and low quinolone resistance): 3
- Norfloxacin 400 mg PO twice daily for 7 days
- Ciprofloxacin 500 mg PO twice daily for 7 days (if oral route available)
Anticoagulant and Antiplatelet Management
Warfarin
- Do NOT routinely give fresh frozen plasma or vitamin K in acute GI bleeding. 5
- If reversal is absolutely necessary for life-threatening hemorrhage, use prothrombin complex concentrate (PCC) rather than fresh frozen plasma. 5
Direct Oral Anticoagulants (DOACs)
- Do NOT administer PCC for DOAC reversal. 5
- Do NOT give idarucizumab (for dabigatran) or andexanet alfa (for rivaroxaban/apixaban) in routine GI bleeding. 5
- Most DOACs have short half-lives (6-14 hours); supportive care and time are usually sufficient 5
Antiplatelet Agents
- Do NOT transfuse platelets for patients on aspirin or clopidogrel. 5
- For patients on aspirin for secondary cardiovascular prevention, do NOT hold aspirin during acute bleeding. 5
- If aspirin was interrupted, resume on the day hemostasis is endoscopically confirmed. 5
- For patients on dual antiplatelet therapy (aspirin + clopidogrel), continue aspirin but consider holding the P2Y12 inhibitor (clopidogrel) temporarily. 5, 6
Risk Stratification and Monitoring
Medications to STOP During Acute Bleeding
- Discontinue beta-blockers, diuretics, and other hypotensive medications immediately. 1, 2, 7
- Avoid nephrotoxic drugs (NSAIDs, aminoglycosides) and large-volume paracentesis. 1, 2
Intensive Monitoring
- Admit to ICU or high-dependency unit for continuous hemodynamic monitoring. 3
- Place central venous access if hemodynamically unstable or requiring vasopressors. 3
- Monitor for complications: 1, 2, 7
- Hepatic encephalopathy (treat with lactulose/lactitol)
- Renal dysfunction (maintain fluid balance, avoid nephrotoxins)
- Bacterial infections (>50% incidence in cirrhotic patients)
- Aspiration pneumonia
Endoscopic Management
Timing
Perform upper endoscopy within 12 hours of admission once hemodynamic stability is achieved. 3, 1, 2, 7
Pre-Endoscopy Preparation
- Administer erythromycin 250 mg IV 30-120 minutes before endoscopy to improve gastric emptying and visualization. 3, 1, 2
- Check QT interval first; avoid if QTc >500 ms 1
Endoscopic Therapy
For Esophageal Varices: 3, 1, 2
- Endoscopic band ligation (EBL) is first-line therapy—it is more effective than sclerotherapy, has fewer complications, and may improve survival.
- Use sclerotherapy only if EBL is technically impossible 3, 1
For Gastric (Cardiofundal) Varices: 3, 1
- Cyanoacrylate injection or EBL are both acceptable.
- Limit EBL to small gastric varices that can be fully suctioned into the device 3
Important caveat: Up to 30% of cirrhotic patients bleed from non-variceal sources (peptic ulcers, Mallory-Weiss tears, portal hypertensive gastropathy), so endoscopy is essential for accurate diagnosis. 1
Rescue Therapy for Treatment Failure
If bleeding persists or recurs despite optimal endoscopic and pharmacologic therapy: 3, 1, 2, 7
First-Line Rescue
- Transjugular intrahepatic portosystemic shunt (TIPS) is the preferred rescue therapy. 3, 1, 2, 7
- Consider early pre-emptive TIPS in high-risk patients (Child-Pugh C <14 or Child-Pugh B with active bleeding at endoscopy) 2
Temporary Bridge
- Balloon tamponade (Sengstaken-Blakemore or Minnesota tube) may be used as a temporary bridge (maximum 24 hours) while awaiting TIPS or transfer to a tertiary center. 3, 1, 2, 7
- Ensure adequate airway protection before insertion 3
Common Pitfalls to Avoid
- Delaying vasoactive therapy until after endoscopy—start immediately when variceal bleeding is suspected 1, 4
- Liberal transfusion strategies—increases portal pressure and mortality; adhere to hemoglobin <7 g/dL threshold 3, 1
- Omitting antibiotic prophylaxis—infections independently predict bleeding failure and death 3, 1
- Performing endoscopy before hemodynamic stabilization—resuscitate first 1, 2
- Continuing beta-blockers during acute bleeding—they worsen hypotension and should be held 1, 2, 7
- Routine reversal of anticoagulation with blood products—avoid unless life-threatening hemorrhage 5
- Holding aspirin in patients on secondary cardiovascular prevention—continue aspirin unless bleeding is uncontrollable 5
