Zorluk: OrtaPharmacologic Interventions

A 54-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 decompensated cirrhosis complicated by ascites. Upon arrival, he appears confused and lethargic. His temperature is 36.8°C (98.2°F), pulse is 122/min, respirations are 22/min, and blood pressure is 86/50 mmHg. Oxygen saturation is 96% on room air. Physical examination reveals scleral icterus, spider angiomas, and a distended, non-tender abdomen with shifting dullness. Two large-bore intravenous lines are placed, and rapid fluid resuscitation with crystalloids and packed red blood cells is initiated. The patient is being prepared for an emergent upper endoscopy. Which of the following pharmacologic interventions should be administered immediately? (Select all that apply.)

  1. Intravenous ceftriaxoneCevap
  2. Intravenous octreotideCevap
  3. C
    Oral nadolol
  4. D
    Oral lactulose
  5. E
    Intravenous tranexamic acid

Cevap

The correct interventions are intravenous ceftriaxone and intravenous octreotide.
The correct interventions are intravenous ceftriaxone and intravenous octreotide. In patients with cirrhosis who present with acute upper gastrointestinal bleeding, there is a very high likelihood of variceal hemorrhage. Medical management must be initiated concurrently with fluid and blood product resuscitation, even prior to diagnostic endoscopy. Intravenous octreotide, a somatostatin analog, is required to induce splanchnic vasoconstriction, which decreases portal venous inflow and lowers variceal pressure. Intravenous ceftriaxone is equally critical as antibiotic prophylaxis; cirrhotic patients with GI bleeding are at an exceedingly high risk for severe bacterial infections (like spontaneous bacterial peritonitis), and administering antibiotics significantly decreases the rate of infection, rebleeding, and overall mortality.

Adım Adım Çözüm

1
Assess the patient's hemodynamic status and clinical presentation.
The patient is in hemorrhagic shock (tachycardia, hypotension) due to an acute upper gastrointestinal bleed, highly suspicious for variceal hemorrhage given the history of decompensated cirrhosis.
Identifying the etiology and severity of the bleed dictates the immediate resuscitation and pharmacologic priorities.
2
Identify the immediate pharmacologic therapies required before definitive endoscopic management.
The patient requires splanchnic vasoconstriction to reduce portal pressure and prophylactic antibiotics to prevent infectious complications.
Endoscopy is the definitive treatment, but temporizing medical therapies significantly improve mortality and procedural success.
3
Select the appropriate specific agents.
Intravenous octreotide provides splanchnic vasoconstriction, and intravenous ceftriaxone provides the necessary broad-spectrum antibiotic prophylaxis.
These two agents are the standard-of-care empirical interventions for cirrhotic patients presenting with suspected variceal hemorrhage.

Anahtar Kavram

Immediate pharmacologic management of suspected variceal hemorrhage in a cirrhotic patient requires a combination of splanchnic vasoconstrictors (e.g., intravenous octreotide) to reduce portal pressure and prophylactic antibiotics (e.g., intravenous ceftriaxone) to prevent infections and rebleeding.
