Upper GI Bleed

Patient presents with hematemesis / melena / coffee-ground emesis consistent with upper GI hemorrhage. Hemodynamically stable on arrival. No signs of hemodynamic compromise after IV fluid resuscitation.

History and exam not consistent with variceal hemorrhage — no stigmata of chronic liver disease, no known cirrhosis. Most likely etiology is peptic ulcer disease versus gastritis/esophagitis versus Mallory-Weiss tear.

Plan: IV PPI initiated — pantoprazole 80 mg bolus then 8 mg/hr drip (or 40 mg IV BID per institutional protocol). Antiemetic. Type and screen sent. GI consulted for endoscopy.
Disposition: Admit for EGD and monitoring. ICU if hemodynamically unstable or actively bleeding.

If hemodynamically stable with low-risk features:

Patient with upper GI bleed who is hemodynamically stable, has no ongoing bleeding, hemoglobin stable, and Glasgow-Blatchford Score of 0–1. After discussion with GI, patient is appropriate for outpatient EGD within 24–72 hours.
Disposition: Discharge with PPI, clear liquid diet, and strict return precautions for recurrent bleeding, hematemesis, melena, lightheadedness, or syncope.

Lower GI Bleed

Patient presents with hematochezia. Hemodynamically stable. Rectal exam reveals bright red blood without evidence of anorectal source (hemorrhoids, fissure).

Differential includes diverticular bleed, angiodysplasia, colitis (ischemic, infectious, IBD), and colorectal neoplasm. Hemodynamic stability and absence of significant anemia suggest non-massive hemorrhage.

If stable and self-limited:

Bleeding appears self-limited. Serial hemoglobin stable. Tolerating PO. No transfusion requirement.
Plan: Outpatient colonoscopy referral for evaluation.
Disposition: Discharge with return precautions for recurrent bleeding, lightheadedness, or persistent bloody stools.

If significant or ongoing:

Patient with significant lower GI hemorrhage requiring resuscitation. Type and crossmatch sent. GI consulted for inpatient colonoscopy. Surgery and IR aware in case of massive hemorrhage requiring angiographic embolization or operative intervention.
Disposition: Admit. ICU if hemodynamically unstable.

Variceal Hemorrhage

Patient with known or suspected cirrhosis presents with hematemesis and hemodynamic instability consistent with variceal hemorrhage. Stigmata of chronic liver disease present.

Aggressive resuscitation initiated. Octreotide 50 mcg IV bolus then 50 mcg/hr drip started. Ceftriaxone 1 g IV given for SBP prophylaxis. Pantoprazole 80 mg IV bolus given. GI consulted emergently for endoscopic band ligation. Massive transfusion protocol activated as needed.

If intubation needed for airway protection:

Active hematemesis with inability to protect airway. RSI performed for airway protection prior to endoscopy. Rocuronium preferred (avoid succinylcholine in hyperkalemic cirrhotics).

Disposition: ICU admission.

Clinical Education

Resuscitation Priorities

Permissive hypotension is appropriate in GI bleeding. Target MAP 65 mmHg. Over-resuscitation with crystalloid and blood products can worsen variceal bleeding by increasing portal pressures and diluting clotting factors. Restrictive transfusion (Hgb threshold 7 g/dL) improves outcomes compared to liberal strategies in most GI bleeding, including variceal.^[1]

Initial hemoglobin may be normal despite significant hemorrhage — it takes 24–72 hours for hemodilution to reveal the true nadir. Rely on hemodynamics (tachycardia, orthostatics, shock index), not the initial Hgb, to guide the urgency of resuscitation.

Two large-bore IVs (18g or larger) and type and crossmatch early. In massive hemorrhage, activate your institution’s massive transfusion protocol. Target 1:1:1 ratio of pRBC:FFP:platelets when transfusing rapidly.

Upper vs Lower GI Bleed

Feature	Upper GI Bleed	Lower GI Bleed
Presentation	Hematemesis, coffee-ground emesis, melena	Hematochezia, maroon stool
Source (ligament of Treitz)	Proximal	Distal
Common etiologies	PUD, varices, Mallory-Weiss, erosive disease	Diverticulosis, angiodysplasia, colitis, hemorrhoids
BUN:Cr ratio	Elevated (>20:1) from digested blood	Normal

Hematochezia can be from an upper source. A briskly bleeding upper GI source can produce bright red blood per rectum — ~15% of hematochezia is from an upper source. If a patient with hematochezia is hemodynamically unstable, think upper GI bleed first.^[2]

Risk Stratification

The Glasgow-Blatchford Score (GBS) identifies patients who may be safe for outpatient management. A GBS of 0–1 identifies very low-risk patients who can be considered for discharge with outpatient EGD. This is one of the few validated tools that can help avoid unnecessary admissions.^[3]

The Rockall Score is useful post-endoscopy for predicting rebleeding and mortality but requires endoscopic findings, so it’s less useful in the ED pre-EGD.

The Oakland Score can risk-stratify lower GI bleeds. Score ≤8 identifies patients with >95% probability of safe discharge.

Variceal Hemorrhage Pearls

Variceal bleed is treated with the triad: octreotide + antibiotics + endoscopy. All three reduce mortality. Don’t forget the antibiotics — ceftriaxone 1 g IV daily for 7 days for SBP prophylaxis reduces bacterial infections and improves survival.^[4]

Octreotide 50 mcg IV bolus followed by 50 mcg/hr drip reduces portal pressure and splanchnic blood flow. Start immediately — don’t wait for endoscopic confirmation. Continue for 3–5 days.^[5]

If bleeding is uncontrolled and endoscopy is delayed or fails, consider a Blakemore or Minnesota tube as a temporizing bridge. This is a rescue device — place it only if you have training and the patient has a protected airway. Balloon tamponade controls hemorrhage in ~80% of cases but has high complication rates (esophageal perforation, aspiration).

Avoid over-transfusion. Restrictive transfusion (Hgb target 7 g/dL) is superior to liberal strategy in variceal bleeding — over-transfusion increases portal pressure and rebleeding risk.^[1]

Anticoagulant Reversal

Agent	Reversal
Warfarin	4-factor PCC (Kcentra) 25–50 units/kg + Vitamin K 10 mg IV
Dabigatran	Idarucizumab (Praxbind) 5 g IV
Rivaroxaban / Apixaban	Andexanet alfa (if available) or 4-factor PCC 50 units/kg
Heparin (unfractionated)	Protamine 1 mg per 100 units heparin (max 50 mg)

Reverse anticoagulation in life-threatening GI hemorrhage. For mild-moderate bleeds on anticoagulation, the decision to reverse should be individualized — consult GI and the prescribing physician regarding the indication for anticoagulation and the risk of thrombosis if reversed.^[6]

PPI in GI Bleeding

IV PPI before endoscopy does not reduce mortality or rebleeding but does downstage ulcer lesion severity, which can reduce the need for endoscopic intervention. It’s still standard practice to start PPI early in suspected upper GI bleeds, but recognize that the primary benefit is facilitating endoscopy rather than stopping the bleed.^[7]

High-dose PPI drip (pantoprazole 80 mg bolus + 8 mg/hr) is traditionally given for suspected high-risk ulcer bleeds. Intermittent dosing (pantoprazole 40 mg IV BID) appears non-inferior in recent data and is simpler to administer.

Disposition

Admit if: Active or recent hemodynamically significant bleeding, transfusion requirement, variceal bleeding (all admitted), high-risk endoscopic features, anticoagulant use with significant bleed, comorbidities requiring monitoring.

Discharge if: GBS 0–1 (upper GI), Oakland Score ≤8 (lower GI), hemodynamically stable, no active bleeding, stable Hgb, able to tolerate PO, reliable follow-up for outpatient endoscopy within 24–72 hours, not on anticoagulants (or anticoagulation management plan in place).
