Due to the size (8-12F) of the NJFTs, meticulous care is needed to prevent clogging of tubes. This is easily managed by flushing the tubes every 2 hours, and BEFORE and AFTER all medications given.
Clogging is due to either lining of the NJFT with a build-up of tube feeds or inappropriate medications given down the tube.
The volume of the tube is so small that no amount of pancreatic enzymes, bicarbonate, cola, etc. is effective to maintain patency for any extended period of time. Prevention of the buildup is essential to ensure a functioning tube.
Recommend flush feeding tube with 20 ml water (may also use pre-filled NS syringes) every two hours. Flush an additional 20 ml BEFORE and AFTER all medications are given. The volume may be increased if patient’s condition and fluid requirements dictate.
For patients who are estimated to require prolonged enteral feeding (>4 weeks) or who are unable to tolerate or maintain a nasoenteric tube, placement of a surgical feeding tube is strongly encouraged if no absolute contraindication is present. For patients requiring prolonged enteral feeding access a gastrostomy tube is preferred over a jejunostomy for ease of management, routine care, and conversion to a simplified bolus tube-feeding regimen.
