A 5656-year-old man is brought to the emergency department after vomiting a large amount of bright red blood. He has a history of alcohol use disorder and was diagnosed with cirrhosis two years ago. On arrival, he is lethargic but easily arousable. His temperature is 37.1∘C37.1^\circ\text{C} (98.8∘F98.8^\circ\text{F}), blood pressure is 88/54 mm Hg88/54\text{ mm Hg}, pulse is 118/min118/\text{min}, and respiratory rate is 20/min20/\text{min}. Physical examination reveals scleral icterus, spider angiomas on the chest, and a distended abdomen with shifting dullness. Arrange the following management steps in the most appropriate chronological sequence for this patient.

  1. 1Establish dual large-bore peripheral intravenous access and initiate crystalloid fluid resuscitation
  2. 2Administer intravenous octreotide and a prophylactic cephalosporin
  3. 3Perform an urgent esophagogastroduodenoscopy with endoscopic band ligation
  4. 4Initiate daily therapy with an oral nonselective beta-blocker

Cevap

The correct sequence of management is: 1) Hemodynamic stabilization with dual large-bore IVs and fluids, 2) Pharmacologic therapy with octreotide and antibiotics, 3) Urgent esophagogastroduodenoscopy for definitive hemostasis, and 4) Initiation of oral nonselective beta-blockers for long-term secondary prophylaxis.
Acute variceal hemorrhage algorithms dictate that basic life support and fluid resuscitation take absolute priority. Once access and fluids are running, adjunctive medical therapies (octreotide and antibiotics) must be given to prepare the patient for intervention. Endoscopy follows as the definitive diagnostic and therapeutic tool. Long-term preventative medications like beta-blockers are reserved for the recovery phase.

Adım Adım Çözüm

1
Assess the patient's hemodynamic status and initiate primary stabilization.
The patient's hypotension (88/54 mm Hg88/54\text{ mm Hg}) and tachycardia (118/min118/\text{min}) indicate hypovolemic shock. Two large-bore IVs and fluids are initiated immediately.
Circulatory collapse is the primary cause of early mortality in acute hemorrhage. Airway, Breathing, and Circulation (ABCs) must be secured first.
2
Initiate empiric medical therapy for suspected variceal hemorrhage.
Intravenous octreotide and prophylactic antibiotics (e.g., ceftriaxone) are administered.
Octreotide causes splanchnic vasoconstriction, reducing active variceal bleeding. Antibiotics prevent spontaneous bacterial peritonitis and other infections, which are proven to improve survival and reduce rebleeding.
3
Localize and control the specific source of gastrointestinal bleeding.
Urgent esophagogastroduodenoscopy (EGD) is performed.
Once the patient is resuscitated, EGD allows for visual confirmation of esophageal varices and application of direct therapy, such as endoscopic band ligation.
4
Plan for long-term prevention of future bleeding episodes.
A nonselective beta-blocker is prescribed prior to hospital discharge.
Beta-blockers reduce portal venous pressure and are the standard of care for secondary prophylaxis, but they are contraindicated during the acute shock phase.

Anahtar Kavram

The management of acute variceal hemorrhage requires a strict sequential progression: immediate hemodynamic stabilization, followed by empiric pharmacotherapy (splanchnic vasoconstrictors and antibiotics), then urgent definitive endoscopy, and finally, long-term secondary prophylaxis once the acute episode resolves.
