So there I was, a few shifts ago, minding my own business,
when I was assigned to a call for a 35-year-old male with abdominal pain. I was driving but I had a strong partner
attending. It was about 7am, but we
found the patient to be pretty heavily intoxicated – blitzed, as a matter of
fact. Hammered. He had upper abdominal pain that radiated to
his back, consistent with his previous experience with pancreatitis.
We found out that he signed out AMA from the nearby hospital
last night during treatment for pancreatitis.
He wanted to leave, get himself all likkerd up, and then take care of
his belly pain. Nice. Anyway, we took him back to the
hospital. My partner blew my mind,
though. You see, normally I hate to be
the driver when running a pancreatitis call.
There are a lot of paramedics who don’t actually treat an intoxicated
pancreatitis patient. Sure, they will
give them a ride to the hospital – usually sitting on the bench rather than the
bed, with a nice rant about how drinking caused their problems so they should
quit drinking thrown in at no extra cost.
I think it is shameful. My
partner on this call, however, started an IV and gave the patient plenty of
Fentanyl along with some fluids.
It bothers me that it seems as though many paramedics don’t
adequately treat pancreatitis patients. I
don’t know what causes that. They either
don’t know what it is, how serious it can be, how painful it probably is, or
don’t want to treat a condition caused by alcohol.
Let me try to fix that.
What is pancreatitis?
In the simplest way of thinking, pancreatitis is
inflammation (-itis) of the pancreas.
The pancreas secretes hormones (e.g. insulin, glucagon, etc.) and
pancreatic juice. Pancreatic juice is
comprised of digestive enzymes that aid digestion and absorption of nutrients
in the small intestine. Pancreatic juice
can be activated in the pancreas, rather than in the small intestine. Digestion outside of where digestion is
supposed to be hurts.

It affects between 5 and 35 people per 100,000, depending on
which study you look at. Mortality is pretty
consistently reported to be about 5% (1.5% in mild and 17% in severe
pancreatitis). Necrotizing pancreatitis
results in even higher mortality.
What causes
pancreatitis?
The most common causes are gallstones and alcoholism. Those two causes result in about 75% of
cases. Other causes include trauma,
steroid use, mumps, autoimmune disease, hyperlipidemia, some medical
procedures, genetic disorders, and (I’m sure) others. But those are the main ones.
The etiology of pancreatitis is not well-understood, but
this is one of the easiest ways to think of what’s going on. A gallstone can travel down the common bile
duct and block the outflow of the pancreatic duct – so pancreatic juice can’t
flow into the duodenum. A fatty,
alcoholic liver can screw with the outflow, as well, by pinching off smaller
pancreatic ductules. Thus, the juice
(especially the trypsin) starts to do its work in the pancreas itself. What we’re talking about is
auto-digestion. That’s as horrible and
painful as it sounds.
Now, I understand that this is overly simplified and there
are other causes of pancreatitis. But this
is a blog post, not a GI textbook entry, and it is a decent model to understand
what’s going on.
Are there different
kinds?
Besides acute and chronic, pancreatitis is also divided into
mild and severe. Essentially, acute
pancreatitis is hurting now and chronic pancreatitis isn’t hurting at the
moment. The difference between mild and
severe is that severe acute pancreatitis results in shock, abscess formation,
necrosis, and/or organ failure. So the
guy at the beginning of the post most likely was suffering from mild acute
pancreatitis.
How does pancreatitis
present?
The most common presentation is upper abdominal pain or left
upper quadrant pain. It can radiate to
the back, and (interestingly) the amount of pain is worse than the amount of
tenderness. Nausea and vomiting
associated with eating is common. Blood
pressure, heart rates, and respiratory rates can all be elevated due to pain,
but blood pressure can be decreased if bleeding or dehydration occurs.
In about three percent of pancreatitis patients, Cullen’s sign
(periumbilical ecchymosis) or Grey-Turner’s sign (flank ecchymosis) are
visible. These are signs of
hemorrhage. So lift a shirt and look at
the belly.

Diagnosis results from characteristic abdominal pain with
elevated blood amylase and lipase. The
blood amylase and lipase can be 3-6 times as high as the normal reference
value. Ultrasound can illuminate the
cause of pancreatitis, such as alcoholic fatty liver or gallstones, plus an
inflamed pancreas is visible. CT scans
can also be helpful.
What should be on the
differential diagnosis list?
Consider other causes of epigastric abdominal pain – peptic
ulcer disease, gallstones (cholelithiasis), acute cholecystitis, perforated
viscus, occult trauma, intestinal obstruction, mesenteric ischemia, and
hepatitis.
What is the treatment
for pancreatitis?
Hospital protocols begin with fluid replacement
(5-10ml/kg/hr of isotonic crystalloid), with reassessment based on lab values
and patient fluid status. Opioid
analgesia is administered – plenty of Fentanyl or Dilaudid are commonly
used. “Plenty” in this case means a
patient administered pump set for 20-50 micrograms of Fentanyl every 10 minutes. Morphine has fallen out of favor for
pancreatitis patients.
Patients are held NPO (nothing per oral) until the pain
decreases and inflammatory markers improve.
While this occurs usually after 24-48 hours, the NPO duration can easily
last 3-5 days. Severe pancreatitis can
result in longer periods without oral food, so enteral or parenteral nutrition
would be required. Antibiotics are used
for extrapancreatic infections. The
symptoms of alcohol withdrawal are treated for admitted alcoholics.
So, what should we be
doing in the field for these patients?
Fluids and analgesia.
Don’t go nuts on the fluids, though.
We can get a liter of crystalloid into a patient in ten or fifteen
minutes, if we try. That would probably
be excessive, except in cases of severe shock.
I just run the IV a little faster than the normal TKO drip rate to end
up delivering a few hundred milliliters during transport. As for analgesia, Fentanyl is a good choice
with a good safety profile.
Pancreatitis is a weird pathology to me. I don’t understand how paramedics can
commonly minimize or ignore the problem.
I have seen medics lecture patients about how drinking with pancreatitis
is dumb, rather than treat the problem.
That doesn’t occur for very many other issues, even those that are
patient caused. We treat suicide
attempts, right? We treat people after
they say, “Hey, ya’ll, hold my beer and watch this!” don’t we? We treat cardiac arrests from alcoholism,
right? Do you think a lecture to a drunk
changes his or her future behavior? Do
you think nontreatment will teach them a lesson?
Please, start treating your pancreatitis patients
appropriately, if you aren’t already.
Even when they are self-intentionally drunk.
