Salem Sump NG Tube Sizes

A comprehensive understanding of Salem Sump NG tube sizes is essential for selecting the right nasogastric (NG) tube for gastric decompression, irrigation, or enteral feeding. Salem Sump tubes are dual-lumen, large-bore catheters that combine a primary suction lumen with a secondary air-vent (pigtail) lumen to prevent mucosal injury and vacuum collapse. Their bore sizes typically range from 6 French (Fr) to 18 Fr, accommodating both pediatric and adult patient needs .

For adult patients, the most commonly used sizes fall between 12 Fr and 18 Fr, with 14 Fr and 16 Fr being the preferred options for effective suctioning without causing excessive discomfort or mucosal trauma . Smaller sizes (6–10 Fr) are reserved for neonatal or pediatric cases, providing adequate drainage while fitting narrower nasal passages. Larger adult tubes (18 Fr) deliver maximum suction flow for thick, viscous secretions or postoperative gastric decompression.

Key considerations when choosing a Salem Sump NG tube size include:

• Suction Efficiency: Larger French sizes offer greater lumen diameter, enhancing drainage of fluid and particulate matter, which is critical in postoperative or high-volume suction scenarios.

  
  

• Patient Comfort: Smaller French sizes reduce nasal and esophageal irritation, improving tolerance during extended dwell times, especially in conscious or long-term care patients.

  
  

• Tube Length & Markings: Standard lengths range from 24" (61 cm) to 48" (122 cm) with centimeter depth graduations to verify accurate placement under radiographic guidance.

By understanding the full spectrum of Salem Sump NG tube sizes—from 6 Fr for pediatric care to 18 Fr for adult decompression—healthcare providers can optimize airway management, ensure patient comfort, and maintain high standards of infection control throughout GI care protocols.
