„
„
Erosive, hemorrhagic gastropathy ( aspirin,
other NSAIDs) (3~11%)
Ulcer: Gastric or duodenal ulcer (35~62%)
Mallory-Weiss tear (4~13%)
Varices – portal hypertensive
gastropathy(4~31%)
Arteriovenous malformation
Maligancy (1~4%)
No source identified ( 7~25%)

Peptic ulcer
„
Phase of GU, DU
Active stage:
A1: well-defined, deep ulceration;
marked bleeding from the ulcer base
marginal welling
A2: stop bleeding
Healing stage (H): H1,H2,H3
Scarred stage (S): S1( red scar), S2(white
scar)

Risk of recurrent bleeding
SRH: stigmata of recent hemorrhage
exposure vessels
adherent clots
arterial spurting or oozing
Endoscopic therapy
HSE (hypertonic saline and epinephrine),
bipolar electrocoagulation, heat probe,
hematoclip, APC
Risk factors

> 60 y/o age
More than one comorbid illness
Blood loss > 5 units
Shock on admission
Bright-red hematemesis with hypotension
Coagulopathy
Large ( > 2cm) ulcer
Recurrent hemorrrhage ( within 72 hrs)
Requirement for emergency surgery

GI bleeding – goals of
management
„
„
„
Hemodynamic stable
Active bleeding stopped
Recurrent bleeding prevented
Hemodynamic stable
„
„
„
„
„
Pulse pressure > 30 mmHg
SBP > 110 mmHg
DBP > 70 mmHg
HR < 100 bpm
Good skin turgor

UGI bleeding -- management
„
„
Restoration of intravascular volume
Hct: > 25%
Hct: > 30% in cardiac or pulmonary dz
Æ Vasopressors indicated ?
Vol resuscitation end-point
CVP=15 mmHg
Wedge pressure = 10 to 12 mmHg
Blood lactate < 4 mmol/ L
Base deficit –3 to +3 mmol/L
C.I. > 3L/min/m2
UGI bleeding -- management

O2 consumption ( V O2) = Q * Hb *
(SaO2-SvO2)
Volume deficit = % loss * normal blood
volume
Males – 70 ml / kg or 3.2 L/ M2
Females – 60 ml / kg or 2.9 L/ M2

UGI bleeding -- management

Correction of coagulopathy
Initial infusion: FFP 2~4 u
Protamine infusion ( 1mg antagonizes
=100 u of heparin)
Vit-K (10 mg,IM): warfarin, hepatobiliary
disease
PLT transfusion: > 50000/cumm
Airway protection
PUD-- treatment
Antacids
drug interaction – Tetracyclines,
Quinolone, ketoconazole,
„ Peptic ulcer ( with evidence)
H2-blocker: Ranitidine (Zantac, Quicran)
side effect: headache, lethargy, confusion,
depression
drug interaction: Cimetidine Æ
β-blockers, Metformin, Phenytoin, Procainamide,
Theophylline, TCA and Warfarin.
„
9
PUD -- treatment
„
„
„
Peptic ulcer ( with evidence)
PPIs: Omeprazole ( Losec)
-- elder
-- intractable bleeding
-- combine with theophylline
Raise intragastric pH to 6~7
Enhance clot stablity decreased further
bleeding (but not mortality)
UGI bleeding -- treatment
„
Variceal hemorrhage
1. Stabilize hemodynamic ( crystal with colloid
supply)
2. Airway patent
3. NG decompression of early detect of rebleeding
4. Octreotide: Somatostatine (Somatosan)
2Amp add N/S to 50ml Æ loading 2ml and
maintain 2ml/ hr

„
Variceal hemorrhage
5. Endoscopic therapy with ligation
6. Sclerotherapy
7. Balloon tamponade Sengstaken-Blakemore
tube
8. Avoid hepatic encephalopathy
9. Prophylaxis: reduce portal hypertensoion
-- Inderal, nitrates
10. Surgery
Recurrent bleeding prevented
„
„
Eradication of H.P Æ rebleeding rate < 5%
Avoid NSAIDs
