Initial Resuscitation
• Appropriate critical paths and equipment/ human resources ( including after- hour assistance) should be in place
• Immediately evaluate and initiate appropriate resuscitation
• Blood transfusions should be administered to a pt. with Hb <7 gm/dl

IV Erythromycin/ MetoclopromideNaso-Gastric tube
• Sampling of luminal contents helpful
• NG lavage RCT- proven, yet requires oro-gastric insertion of large-bore tube(airway)
• Also decrease likelihood of blood in stomach
• No improvement in, mortality, re-bleeding transfused units, or surgery
• Should not be used routinely, selected pts
• EKG is needed before erythromycin(QT)

The benefits of early endoscopy
Early Endoscopy(first24 hrs) allows for: safe and prompt discharge pts classified low risk
improves pt outcomes for pts classified as high risk (blood transfusion, LOS)
reduces resources utilization for pts classified either low or high risk
Recent observational data suggest early endoscopy decreases the need for surgery and may improve mortality
NVUGIB pts admitted on weekends had a higher adjusted in-hospital mortality Barkun,2003, Shaheen,2009,Cooper 2009

Proposed Selection Criteria for an Abbreviated Hospital Stay or Outpatient Treatment of Patients at Low Risk.*Criteria
1-Age, <60 yr
2-Absence of hemodynamic instability, which is defined as resting tachycardia
(pulse, ≥100 beats per minute), hypotension (systolic blood pressure,
< 100 mm Hg), or postural changes (increase in pulse of ≥20 beats per
minute or a drop in systolic blood pressure of ≥20 mm Hg on standing,(
or hemodynamic stability within 3 hours after initial evaluation
3-Absence of a severe coexisting illness (e.g., heart failure, chronic obstructive
pulmonary disease, hepatic cirrhosis, hematologic cancer, chronic renal
failure, and cerebrovascular accident(
4-A hemoglobin level of more than 8 to 10 g per deciliter after adequate intravascular
volume expansion and no need for blood transfusion
5-Normal coagulation studies
6-Onset of bleeding outside the hospital
7-Presence of a clean-base ulcer or no obvious endoscopic finding on early endoscopy
) performed within 24 hours after presentation(
8-Adequate social support at home with the ability to return promptly to a hospital
Hemostatic modalities
Which is the best endoscopic hemostatic modality?
Not epinephrine injection alone Thermal therapy, sclerosant therapy, clips,
and thrombin/ fibrin glue all appear to be effective endoscopic hemostatic therapies
Thermal alone OR clips alone As good as injection+thermal?

Why controversy about adherent clot• A finding of clot in an
ulcer bed warrants targeted irrigation in attempt at dislodgment, with an appropriate Rx of the underlying lesion.
• Marked variability in study design
• Laine Gastro 2005129, 2127• Kahi gastro2005 129,855
• In a pop with rates of re-bleeding with clots, endo Rx is likely to decrease re-bleeding
• High quality blinded trials indicate that the use of modern intensive PPIRx without endo Rx in pts with clots may result in extremly low rates of rebleeding(0/86, 2 studies
What About elevated INR and endoscopy
• A presenting INR<1.5 does not predict re-bleeding yet is an independent predictor of subsequent death following an admission due to NVUGIB
• Correction of INR to 1.8 as part of intensive resuscitation measures may improve mortality
• Endoscopy Rx may be safely performed in pts with an INR of<2.5
• “ in pts on anticoagulant, correction of coagulopathy is recommended but should not delay endoscopy”
Barkun, DDW 2009
Second look endoscopy
• Re-bleeding was significantly decreased by routine second-look endoscopy.
• BUT when taking into account trial limitations and heterogeneity( both clinical & statistical), and current standard of high-dose iv PPI, this approach should probably be reserved to selected pts at especially high risk of re-bleeding

?additional effect of PPI’s?
Cochrane meta-analysis
Effect of PPI on outcomes of pts with PUD bleeding
• PPI improve mortality in pts w HRS only if they have initially undergone endoscopic homeostasis(i.e, mainly high dose iv)
• Also, these findings have been confirmed in a “real-life” setting
• Optimal dose and rout of administration still unclear, but most solid data and recommendation are for high dose IV PPI
So What to Do?Subgroup selection• Efficacy at best marginal, so PPI should NOT
replace the role of adequate resuscitation and early endoscopy
• Can provide PPI before endoscopy or not; more likely to be cost effective IF:
Delay to endoscopy(over 16hours) Pt more likely to be bleeding from a non variceal source
high risk lesion(hematemesis (bloody NGT)
• If you are going to use, high-dose preferred Barkun AN GIE 2008
In patients awaiting endoscopy,
empiric therapy with high dose
proton pump inhibitor should be
considered

Other aspects of in-hospital course
• Pt with Low risk, early feeding• Most pts have undergone endoscopic
intervention for HRS should be hospitalized for at least 72 hrs thereafter
• Surgical consultation for patients who have failed endoscopic Rx,
• Percutaneous embolization instead of surgery , in pts having failed endoscopic Rx
Discharge PPI dosing
• Patients should be discharged on single daily dose of PPI for a duration dictated by underlying etiology
• If bleeding from esophagitis consider double dose
• Length of Rx varies according to location of ulcer and use of Aspirin, clopidogrel

Conclusion
• ABC’s and appropriate resuscitation critical• Early risk stratification, including early
endoscopy• Early discharge for very low-risk pts• Endoscopic hemostasis for high-risk lesions • High doses IV PPI, are adjuvant to endoscopic
hemostasis• Secondary prophylaxis needed for pts w :- H pylori or NSAIDs/COX2, ASA/ clopidogrel
