Acute pancreatitis: pain, nothing by mouth, fluids and watching for complications
- Safe practice
Acute pancreatitis care: treat the pain early, give fluids with frequent checks, feed early as ordered and watch breathing, kidneys and circulation.
What it is
Acute pancreatitis is a sudden inflammation of the pancreas, most often from gallstones or alcohol. Most patients improve within a week, but some develop organ failure, infected necrosis or fluid collections. Nursing care centres on pain control, intravenous fluids guided by repeated assessment, a short pause in eating followed by early feeding, close watch on breathing, kidneys and circulation, and teaching to prevent another attack. Causes and severity scores are on the condition page.
What it requires
- Pain: score, site (upper middle or left abdomen), spread to the back, worse after eating or lying flat.
- Vital signs, oxygen saturation and respiratory rate.
- Fluid balance and urine output.
- The results the team follows: haematocrit, urea, creatinine and lactate.
- Nausea, vomiting and the gastric tube output when one is in place.
How it is applied (and why)
- Assess pain with a scale; give analgesia as prescribed and reassess — pain control is a priority from the first day.
- Let the patient find a comfortable position — lying flat can make the pain worse.
- Give IV fluids as prescribed and check vital signs, urine output and signs of overload — perfusion without overload.
- Monitor respiratory rate, oxygen saturation and work of breathing — lung injury is a known complication.
- Keep nil by mouth only as ordered and start feeding early as prescribed — gut feeding protects against infection.
- Insert or manage a nasogastric tube if vomiting and pain persist, as ordered — it drains the stomach.
- Follow haematocrit, urea and creatinine and report a rise — they track volume and perfusion.
- Report new fever or a patient who gets worse after improving — infected necrosis may need drainage.
- Before discharge teach: no alcohol, quit smoking, low-fat meals and follow-up of the cause — it prevents another attack.
In nursing practice
- Gallstones are the most common cause, then heavy alcohol use; treating the cause prevents recurrence.
- Organ failure lasting under 48 hours means moderate disease; longer than 48 hours means severe disease.
- Routine preventive antibiotics are not recommended; antibiotics are used when infected necrosis is established.
- NSAIDs are avoided when there is acute kidney injury.
- Possible complications include kidney failure, lung injury, fluid in the abdomen, pseudocysts and abscesses.
Common mistakes
- Under-treating pain: the guideline says every patient should receive analgesia in the first 24 hours.
- Keeping the patient nil by mouth longer than ordered without raising feeding with the team.
- Running fluids without reassessing for overload.
- Missing a slowly rising respiratory rate.
Test yourself
Think of the answer, then tap the question to see it.
Why is early feeding through the gut preferred in acute pancreatitis?
Enteral nutrition prevents gut failure and infectious complications; total parenteral nutrition is avoided and used only if enteral feeding fails.
How are IV fluids guided in acute pancreatitis?
By frequent reassessment of vital signs, urine output and signs of overload, with haematocrit, urea and creatinine, because both too little and too much fluid harm.
What defines severe acute pancreatitis?
Organ failure that lasts more than 48 hours.
What does the patient need to know before going home?
Avoid alcohol and smoking, eat low-fat food, and keep the follow-up for the cause, such as gallstones or high triglycerides.
