  24. Modifications of Sengstaken and Blakemore tube?
    • Sengstaken and Blakemore tube - triple-lumenQ
    • Minnesota tube - Addition of a fourth port above the esophageal balloon for aspiration of oral and esophageal secretions
    • Development of a single balloon Linton-Nachlas tube (for gastric varices)Q.
  25. Management of airway during balloon tamponade?
    Protected by placement of an endotracheal tubeQ.
  26. Volume of balloon in Sengstaken–Blakemore tube?
    • Gastric balloon is inflated with with 300 ml of airQ
    • If bleeding does not stop promptly, esophageal balloon may be inflated to a pressure of 40 mm HgQ.
  27. Mechanism of vitamin A induced Hepatotoxicity?
    • • Excess vitamin A is stored in stellate cellsQ in the liver and accumulation can lead to their activation and hypertrophy, excess collagen production, fibrosisQ and liver injury.
    • Liver biopsy is diagnosticQ
  28. Porto-Systemic Anastomosis in Esophageal varices?
    Left gastric veinQ - Azygous veinQ and accessory hemiazygous vein

    • Variceal – 20%, Gastroesophageal varices most common Q
  34. What is Model for End-Stage Liver disease (ME LD) Score?
    • • MELD score is used to assess the severity of chronic liver diseaseQ
    • • It was initially developed to predict death within 3 months of surgery in patients that had undergone TIPS.Q
    • • It is calculated by using 3 variables (CBI): S. Creatinine, S. Bilirubin, INRQ [@ CBI]
  35. Pediatric End-Stage Liver disease (PELD) Score?
    • PELD score utilizes following variables (NABIA)Q:
    • 1. Nutritional statusQ
    • 2. AgeQ
    • 3. BilirubinQ
    • 4. INRQ
    • 5. AlbuminQ
  36. USG finding of esophageal varices?
    • Thickened sinus, interrupted mucosal folds (earliest sign)Q
    • The “worm-eaten” smooth lobulated filling defectsQ
  37. Most significant clinical finding associated with portal HTN?
    • GE varicesQ.
    • Each episode of bleeding is associated with a 20-30% risk of mortalityQ, Seventy percent of patients who survive the initial bleed will experience recurrent variceal hemorrhage within 1 year, if left untreatedQ
  38. Role of antibiotics in UGI bleeding?
    • • Cirrhotic patients with variceal bleeding have a high risk of developing bacterial infectionsQ
    • • Bacterial infections are associated with rebleeding and a higher mortality rateQ.
    • • Use of short-term prophylactic antibiotics has been shown both to decrease the rate of bacterial infections and to increase survivalQ.
    • • Ceftriaxone 1 g/day IV is often givenQ.
