This study evaluated nine substances for declogging small-bore feeding tubes. None were fully effective within four hours, though chymotrypsin, papain, and distilled water allowed for later irrigation.

Area of Science:

  • Gastroenterology
  • Biomedical Engineering
  • Clinical Nutrition

Background:

  • Small-bore feeding tubes are essential for nutritional support.
  • Tube occlusion is a common complication, leading to treatment interruption.
  • Effective declogging agents are needed to maintain tube patency.

Purpose of the Study:

  • To assess the efficacy of nine different substances in declogging small-bore feeding tubes.
  • To identify agents that can successfully clear occlusions and allow for irrigation.

Main Methods:

  • Nine substances, including enzymes, juices, and water, were tested.
  • Substances were applied every 30 minutes for 4 hours under 900 mm water pressure.
  • Tube patency was assessed by air irrigation using a 50-cc syringe post-treatment.

Main Results:

  • No tested substance effectively declogged the tubes within the 4-hour trial period.
  • Three substances—chymotrypsin, papain, and distilled water—enabled successful syringe irrigation after 4 hours.
  • Enzymatic and simple aqueous solutions showed potential for facilitating irrigation.

Conclusions:

  • Standard enzymatic and aqueous solutions may aid in declogging feeding tubes after prolonged contact.
  • Further research is needed to optimize treatment duration and substance concentration for effective declogging.
  • Chymotrypsin, papain, and distilled water represent potential agents for managing feeding tube occlusions.
