Introduction Dilated submucosal esophageal veins due to cirrhosal portal hypertension are tributaries of the left gastric vein found in lower 1/3 of esophagus associated with painless bleeding Evaluation Consider major risk factors and history to consider sources of bleed NSAID use, alcohol use, liver disease / known varices, severe retching, prior abdominal surgery, trauma, coagulopathy, anticoagulation Physical exam vital signs with orthostatics HEENT: epistaxis, telangiectasias, dried blood in oropharynx abdominal exam: ascites, peritoneal signs, distension rectal exam (black/tarry = melena; bright red blood = hematochezia), palpable masses, external anal findings (e.g. hemorrhoids, fissures) Nasogastric tube coagulopathy and varices are not contraindications for NG tube placement. lack of blood in NG aspirate does not rule out upper GI bleed as it may have only sampled gastric content (bleed may be duodenal) Endoscopy important for assessment and treatment Treatment Resuscitation IV crystalloids RBC and fresh frozen plasma transfusions if indicated Pharmacologic proton pump inhibitors (can be discontinued if there is no ulcer) β-blockers used in patients with proven variceal bleeds after the acute bleed has resolved and after octreotide use nonspecific beta blockers (propranolol, nadolol) can be used as secondary prophylaxis against variceal re-bleeding isosorbide mononitrate venodilator; reduces portal pressure ceftriaxone reduces variceal re-bleeding, infection, and mortality in patients with cirrhosis with or without ascites octreotide acts as a somatostatin analogue (constricts splanchnic circulation) Surgical transjugular intrahepatic portasystemic stent (TIPS) Complications Massive hematemesis results from venous rupture

She is accompanied by her partner, who reports that she had been complaining of black and tarry stools for the past several days. Vital signs are temperature 37 degrees celsius, heart rate 141 beats per minute, blood pressure 90/60, respiratory rate 20, and oxygen saturation 99% on room air. On physical examination, she has splenomegaly and a positive fluid wave. The remainder of her examination is within normal limits. The patient is stabilized with intravenous fluids, and her blood pressure improves. Subsequent emergent upper endoscopy reveals bleeding from the submucosal veins in the lower 1/3 of the esophagus, but no gastric bleed. In the endoscopy suite she also receives IV octreotide. After intervention and resolution of her acute bleed, which of the following pharmacologic agents is indicated?
