| ==Background==
| | {{GI bleeding pages}} |
| *Bleeding originating proximal to ligament of Treitz
| |
| | |
| ==Diagnosis==
| |
| ===History===
| |
| *Hematemesis
| |
| *Coffee-ground emesis
| |
| *Melena + age <50 suggests upper GI bleed
| |
| *Vomiting + retching followed by hematemesis = Mallory-Weiss
| |
| *Aortic graft = aortoenteric fistula
| |
| *Meds
| |
| **ASA, steroids, NSAIDs, anticoagulants
| |
| *ETOH abuse
| |
| **Peptic ulcer disease, gastritis, varices
| |
| *Pseudo-melena
| |
| **Iron or bismuth use
| |
| ===Physical Exam===
| |
| *Tachycardia, hypotension
| |
| *Liver disease
| |
| **Spider angiomata, palmar erythema, jaundice, gynecomastia
| |
| *Coagulopathy
| |
| **Petechiae/purpura
| |
| *ENT exam
| |
| **Swallowed blood may result in coffee-ground emesis or melena
| |
| *Rectal exam

| #Peptic ulcer disease (most common cause)
| |
| #Gastritis/esophagitis
| |
| #Gastric/esophageal varices
| |

| ==Workup==
| |
| #2 large bore IV
| |
| #Type and cross
| |
| #CBC & serial Hb
| |
| #Chemistry
| |
| ##BUN/Cr >30 suggests UGI if no hx of renal failure (incr absorption/digestion of hb)
| |
| #Coags (if INR > 1.5 transfuse FFP)
| |
| #LFTs
| |
| #Guaiac
| |
| #?ECG (if >50 yo or if suspicious for silent MI)
| |
| #?CXR (if suspect perforation)
| |
| #?NG lavage
| |
| ##Controversial
| |
| ###Pros
| |
| ####Positive aspirate proves strong evidence for an UGI source of bleeding
| |
| ####Can assess presence of ongoing active bleeding
| |
| ####Can prepare pt for endoscopy
| |
| ###Cons
| |
| ####Uncomfortable
| |
| ####Negative aspirate does not conclusively exclude UGI source
| |
| ####Provides useful information in only minority of pts w/o hematemesis
| |
| ####Erythromycin 200mg IV can provide equal endoscopy conditions as lavage
| |
| | |
| ==Treatment==
| |
| #IVF
| |
| #Blood
| |
| ##Indications for tranfusion:
| |
| ###Continued active bleeding
| |
| ###Failure to improve perfusion and vital signs after infusion of 2L NS
| |
| #FFP as needed
| |
| #PPI
| |
| ##Pantoprazole/esomeprazole 80mg x 1; then 8mg/hr
| |
| ##Lansoprazole 60mg x 1; then 6mg/hr
| |
| #Octreotide
| |
| ##25-50mcg x 1; then 25-50 mcg/hr
| |
| ###Use lower dosage for elderly or severe liver disease
| |
| #Ceftriaxone
| |
| #Endoscopy
| |
| #Surgery
| |
| #Balloon tamponade (for life-threatening hemorrhage if endoscopy is not available)
| |
| ##Sengstaken-Blakemore tube
| |
| ###Tube consists of gastric and esophageal balloons
| |
| ####First inflate gastric balloon; if bleeding continues inflate esophageal balloon
| |
| #####Esophageal pressure must not exceed 40-50 mmHg
| |
| ###Adverse reactions are frequent
| |
| ####Mucosal ulceration
| |
| ####Esophageal/gastric rupture
| |
| ####Tracheal compression (consider intubation prior to balloon insertion)
| |
| | |
