Parenteral Nutrition (TPN) — Line Emergencies

Signs of CRBSI (Line Infection)

CRBSI (Catheter-Related Bloodstream Infection) is a serious complication of TPN lines.

  • Temperature >38°C or <36°C
  • Shivering, rigors (uncontrollable shaking) — especially during infusion
  • Redness, swelling or discharge at the line entry site
  • Feeling suddenly unwell during or after infusion
  • Rapid heart rate or low blood pressure
STOP the infusion immediately. Call your nutrition nurse or go to A&E. Do not restart until assessed.

Blocked or Damaged Line

  • If pump shows occlusion alarm — stop infusion, do not force flush
  • Never use excessive force to flush a blocked line
  • Contact your nutrition nurse or IV pharmacy for guidance
  • If the line appears cracked or damaged — clamp it and call immediately

Accidental Line Disconnection

  • Clamp the line immediately to prevent air entry
  • Lie flat if possible — reduces risk of air embolism
  • Do not reconnect yourself unless trained to do so
  • Call your nutrition nurse immediately or go to A&E

Air in the Line

  • Small bubbles in tubing are usually harmless
  • Large air bubble or pump air alarm — stop infusion
  • Lie on your left side, head down if possible
  • Call 999 if you feel chest pain, breathlessness, or collapse

Enteral Nutrition — Tube Emergencies

NG Tube Has Come Out

  • Stop the feed immediately
  • Do NOT reinsert an NG tube yourself
  • Do NOT restart the feed until tube position is confirmed by pH testing or X-ray
  • Contact your nutrition nurse or go to hospital for reinsertion
Feeding into a misplaced NG tube can be life-threatening.

PEG / Gastrostomy Tube Issues

  • Tube has fallen out: Cover the stoma site with a clean dressing. Go to hospital within 4–6 hours — the stoma can close quickly
  • Leaking around tube: Contact nutrition nurse — do not increase balloon water
  • Buried bumper: Tube feels stuck or pain when rotating — contact your team, do not force it
  • Skin infection around site: Redness, discharge, odour — contact team for antibiotic assessment

Vomiting During Feed

  • Stop the feed
  • Sit upright — never lie flat after vomiting during tube feeding
  • Check tube position before restarting
  • If vomiting repeatedly or vomiting feed — contact your nutrition team
  • Signs of aspiration: coughing, breathlessness, chest pain → call 999

Pump Alarm Guide

  • Occlusion: Kink in tube or tube kinked at site — check the line, do not force
  • Air in line: Re-prime giving set
  • End of feed: Normal — remove bag, flush tube per your care plan
  • Low battery: Connect to mains power
  • Dose complete: Feed finished — flush per plan

Other Urgent Situations

Signs of Dehydration

  • Dark urine, dry mouth, headache
  • Dizziness when standing, rapid heartbeat
  • High urine output through stoma without replacement

Contact your nutrition team if you are not meeting your fluid prescription. Go to A&E if severely unwell.

Low Blood Sugar (if applicable)

  • Shaking, sweating, confusion, feeling faint
  • TPN patients: do not stop infusion suddenly — taper if needed
  • Contact your team if blood glucose is consistently low or high
