Study Notes
Acute Pancreatitis
- Cause: The body "autodigests" the pancreas, caused by the release of stored enzymes (trypsin, phospholipase A, amylase, elastase) within the pancreas instead of being excreted to the duodeum
- Pathophysiology: The pancreas normally has a protective mechanism with trypsin inhibitor to prevent enzyme activation before reaching the duodenum, but this mechanism fails in pancreatitis, leading to autodigestion
- Diagnosis: Requires two out of three criteria:
- Abdominal pain or epigastric pain (possibly radiating to the back)
- Serum amylase or lipase at least two to four times the normal range (Lipase is generally more sensitive)
- Characteristic findings on imaging (ultrasound is often used)
- BISAP Score: Used to assess severity based on five variables:
- BUN > 25 mg/dL
- Impaired mental status
- Polyphagia: Excessive eating due to a lack of glucose reaching the cells
- Decreased PaO2 (< 60 mmHg) and O2sat (< 90%)
- Pleural effusion on imaging
- Each variable scores 1 point.
- Scores of 3, 4, and 5 are associated with higher hospital mortality.
- Score of 5 carries a 22% mortality rate.
- Management:
- Fluid resuscitation: IV isotonic crystalloids to replace fluid losses due to third spacing, vomiting, and vascular permeability
- Pain Management: Opiates are generally discouraged, focus on positioning (knee-chest) and comfort
- Preventing Pancreatic Stimulation: Low fat, low residue oral feeding may be considered after 24-48 hours, but EN with jejunal feedings is often preferred
- Treating Local Complications: Percutaneous/stent therapies to drain fluids, surgical resection/debridement if pancreas becomes infected, biliary ERCP or laparoscopic cholecystectomy for gallstone pancreatitis
- Endocrine Disorders: Result from too much or too little hormone, with a diagnostic focus on fasting blood glucose, glucose tolerance, and HbA1c
- Vascular Problems: Neuropathy can lead to impaired sensation, numbness, tingling, weakness, and muscle wasting
- Risk Factors:
- Chronic alcohol use
- Gallstones/biliary tract disease
- Less common factors include drug-induced (metronidazole, tetracycline, azathioprine, estrogens)
- Clinical Manifestations:
- Acute Pain: Severe, relentless, knifelike, in the midepigastrium or periumbilical region
- Fluid Volume Deficit: Hypotension mental status changes, tachycardia, cool clammy skin, decreased urine output
- Impaired Gas Exchange:
- Abdominal Guarding: Rebound tenderness
- Vomiting and Nausea:
- Hypoactive Bowel Sounds:
Diabetes
- Complications:
- Short-term: Hypoglycemic shock and diabetic ketoacidosis (DKA)
- Long-term: Result from long-term increased blood glucose
- Hypoglycemic Shock:
- Cause: Excessive insulin, leading to a glucose deficit
- Symptoms: Poor concentration, slurred speech, staggering, appearing intoxicated, increased heart rate, anxiety, tremors
- Management: Rapid-acting insulins (Humulin R)
- Insulin Management: Adjust insulin rates based on blood glucose levels to avoid hypoglycemia
- Diabetic Ketoacidosis (DKA)
- Cause: Lack of insulin leading to an inability to utilize glucose, the body attempts to use fat for energy, resulting in ketone production
- Symptoms: Frequent urination, thirst, rapid breathing, fruity breath odor, lethargy, confusion, coma, abdominal pain, nausea, vomiting
- Severity:
- Mild: Glucose > 300 mg/dL, bicarbonate 15-18 mEq/L, pH < 7.30
- Moderate: pH < 7.20, bicarbonate 10-14 mEq/L, increasing drowsiness
- Severe: pH < 7.10, bicarbonate < 10 mEq/L, decreased levels of consciousness or coma
- Management:
- Fluid replacement with 0.9% saline
- Electrolyte imbalances are corrected
- Insulin is administered at a slow continuous rate, with close monitoring of volume and electrolytes
- Prevention: "Sick Day Rules" to prevent episodes of DKA by managing blood glucose during periods of illness
