Zorluk: OrtaPharmacologic Interventions

Paramedics arrive at the emergency department with a 55-year-old male patient who experienced a massive episode of hematemesis at home. His medical history is significant for alcohol use disorder and biopsy-proven cirrhosis. On initial assessment in the resuscitation bay, the patient appears pale, diaphoretic, and confused. Vital signs show a blood pressure of 82/50 mmHg, a heart rate of 122/min, and an oxygen saturation of 95% on ambient air. Physical examination demonstrates scleral icterus, a distended abdomen with shifting dullness, and cutaneous spider telangiectasias. Intravenous access is established with two 16-gauge peripheral catheters, and rapid volume expansion with isotonic crystalloids is underway. The gastroenterology service is notified for an emergent upper endoscopy.

Which of the following pharmacologic therapies should be initiated concurrently? (Select all that apply)

  1. Intravenous octreotideCevap
  2. Intravenous ceftriaxoneCevap
  3. C
    Oral nadolol
  4. D
    Enteral lactulose
  5. E
    Intravenous furosemide

Cevap

The correct interventions are intravenous octreotide and intravenous ceftriaxone.
For a patient with cirrhosis presenting with an acute upper gastrointestinal bleed, immediate pharmacologic stabilization is required alongside rapid volume resuscitation. Intravenous octreotide is a somatostatin analog that induces splanchnic vasoconstriction, thereby decreasing portal blood flow and variceal pressure to aid hemostasis. Concurrently, intravenous ceftriaxone is indicated as prophylactic antibiotic therapy. Cirrhotic patients with gastrointestinal bleeding have a high risk of developing severe bacterial infections (such as spontaneous bacterial peritonitis or bacteremia), and prophylactic antibiotics have been proven to significantly reduce both rebleeding rates and overall mortality.

Adım Adım Çözüm

1
Identify the primary clinical emergency
The patient has an acute variceal hemorrhage resulting in severe hypovolemic shock.
The patient has a history of cirrhosis, stigmata of chronic liver disease, large-volume hematemesis, and profound hypotension with compensatory tachycardia.
2
Determine concurrent stabilization priorities alongside volume expansion
Initiate splanchnic vasoconstriction and administer prophylactic antibiotics.
These interventions actively decrease variceal bleeding and prevent highly lethal infectious complications (like spontaneous bacterial peritonitis) prior to definitive endoscopic management.
3
Exclude contraindicated routine cirrhosis medications
Nadolol, lactulose, and furosemide are withheld.
Beta-blockers and diuretics actively worsen hypovolemic shock; enteral lactulose in a vomiting, confused patient poses a severe aspiration risk.

Anahtar Kavram

In acute variceal hemorrhage, immediate pharmacologic management must include a splanchnic vasoconstrictor (such as octreotide) and prophylactic antibiotics (such as ceftriaxone) while strictly avoiding routine cirrhosis medications that exacerbate shock or pose an aspiration risk.
