Remember the common (and not so common) causes of pancreatitis (I GET SMASHED):
Idiopathic
Gallstones
ETOH
Trauma
Steroids
Mumps
Autoimmune
Scorpion stings (species found on the island of Trinidad)
HyperTG/Ca2+
ERCPs
Drugs
* Gallstones and alcohol account for approximately 80% of all cases in the US
Diagnosis of pancreatitis (requires 2 of 3):
- Typical clinical symptoms
- Elevated Lipase > 3 x the ULN
- Imaging findings consistent with pancreatitis
Clinical predictors of worse prognosis:
- Older age (usually 55-75 years old)
- Alcohol – increased risk for pancreatic necrosis and need for intubation
- Obesity (BMI > 30) OR 2.9
- Multiple medical co-morbidities
Management Principles:
- Fluid Replacement
- 5-10 mL/kg/hr of isotonic crystalloid solution unless contraindicated
- Avoid LR in patients with hypercalcemia since it contains calcium
- Re-evaluate frequently in the first 6 hours and adjust rate as necessary
- Pain Management
- Typically IV opiates in PCA form
- Dilaudid/fentanyl are good choices; morphine has been shown to increase sphincter of Oddi pressure, but no studies exist to suggest worse outcomes
- Nutrition
- Oral feeds can be resumed in mild pancreatitis as soon as pain controlled/patient hungry
- Enteral feeds are preferred over parental feeds; place NJ tube beyond ligament of Trietz if possible – but NG preferred to NPO
- Antibiotics
- prophylactic antibiotics are not recommended regardless of the type (interstitial/narcotizing) or severity (mild/moderate/severe)
