Acute Ethanol Intoxication And The Banana Bag

It’s one of those time honored treatments that most hospital-based providers are familiar with. The banana bag, reserved for intoxicated patients presenting to the ED or admitted to the hospital. They’ve been around so long, we just take them for granted. But like most things that have become dogmatic, they are due to be questioned from time to time.

A banana bag is a proprietary mix of “good” stuff, including electrolytes and vitamins, especially thiamine and magnesium. The exact content varies from hospital to hospital. Thiamine and other B vitamins give the resulting solution the characteristic color, hence the term “banana.”

Does it actually do good things like ward off Wernicke’s encephalopathy and megaloblastic anemia? A paper from Jacobi Medical Center in the Bronx prospectively evaluated a series of intoxicated people entering their ED. They drew vitamin B12, folate, and thiamine levels to see if they were deficient enough to even need vitamin supplementation.

Interesting findings:

  • These folks (only 77 patients) were very drunk! Average BAC was 280mg/dL.
  • Vitamin B12 and folate levels were not critically low in any patient
  • Thiamine was low in 15% of patients, but none had clinical evidence of a deficiency
  • Later review of prior visits revealed that some patients with low levels had received a previous banana bag within 1 month. Did it do any good?

Bottom line: Most of our intoxicated patients are not vitamin deficient, and don’t need supplementation. The real kicker is that  we almost never really try to find out if the patient might be a chronic abuser and potentially at risk. We just hang the bag. Remember, everything we do in medicine has a potential downside. And if the patient really doesn’t need a banana bag in the first place, there is no benefit to balance that risk. The next time you ask for that little yellow bag, think again!

The Value of Protocols in Trauma

Most trauma centers have a book of practice protocols or guideleines. Actually, it is required by the American College of Surgeons verification standards. All centers must have a massive trauma protocol. Many have pain management or alcohol withdrawal or a number of other protocols. The question sometimes arises: why do we need another protocol? Can we show some benefit to using a protocol?

I’ve looked at the literature, and unfortunately there’s not a lot to go on. Here are my thoughts on the value of protocols.

In my view, there are a number of reasons why protocols need to be developed for commonly encountered issues.

  • They allow us to build in adherence to any known practice guidelines or literature.
  • They help conserve resources by standardizing care orders and resource use.
  • They reduce confusion. Nurses do not have to guess what cares are necessary based on the specific admitting surgeon.
  • They reduce errors for the same reason. All patients receive a similar regimen, so potential errors are more easily recognized.
  • They promote team building, particularly when the protocol components involve several different services within the hospital.
  • They teach a consistent, workable approach to our trainees. When they graduate, they are familiar with a single, evidence based approach that will work for them in their practice.

A number of years ago, we implemented a solid organ injury protocol here at Regions Hospital. I noted that there were large variations in simple things like time at bedrest, frequency of blood draws, how long the patient was kept without food and whether angiography should be considered. Once we implemented the protocol, patients were treated much more consistently and we found that costs were reduced by over $1000 per patient. Since we treat about 200 of these patients per year, the hospital saved quite a bit of money! And our blunt trauma radiographic imaging protocol has significantly reduced patient exposure to radiation.

Bottom line: Although the proof is not necessarily apparent in the literature, protocol development is important for trauma programs for the reasons outlined above. But don’t develop them for their own sake. Identify common problems that can benefit from consistency. It will turn out to be a very positive exercise and reap the benefits listed above.

Phlebotomy And Pediatric Solid Organ Injury

I recently wrote about this journal article from a couple of pediatric trauma programs in New York. The article tried to focus on reducing the rate of phlebotomy in children who are being observed for solid organ injury. I was more excited about the overall protocol being used to manage liver and spleen injury, as it was a great advance over the original APSA guideline. But let’s look at the phlebotomy part as well.

This is an interestingly weird study, and you’ll see what I mean shortly. Two New York trauma hospitals that take care of pediatric patients pooled 4 years of registry records on children with isolated blunt liver and/or spleen injuries. Then they did a tabletop excercise, looking at “what if” they had applied the APSA guideline, and “what if” they had applied their new, proposed guideline.

Interestingly, this implies that they were using neither! I presume they are trying to justify (and push all their partners) to move to the new protocol from (probably) random, individual choice.

Here are the factoids:

  • 120 records were identified across the 2 hospitals that met criteria
  • Late presentation to the hospital, contrast extravasation, comorbidities, lack of imaging, operative intervention at an outside hospital excluded 59 patients, leaving 61 for analysis. Three of those patients became unstable and were also excluded.
  • None of the remaining patients required operation or angioembolization
  • Use of the “new” (proposed) protocol would reduce ICU admissions by 65%, reduce blood draws by 70%, and reduce hospital stay by 37%
  • Conclusion: use of the protocol would eliminate the need for serial phlebotomy (huh?)

Bottom line: Huh? All this to justify decreasing blood draws? I know, kids hate needles, but the data on decreased length of stay in the hospital and ICU is much more important! We’ve been using a protocol similar to their “new” one at Regions Hospital, which I’ve shared below. We’ve been enjoying decreased resource utilization, blood draws, and very short lengths of stay for over a decade. And our analysis showed that we save $1000 for every patient entering the protocol, compared to the old-fashioned and inefficient way we used to manage them.

Chest Tube Management Protocol – Pediatric

Yesterday I described a protocol for deciding when to remove a chest tube in adults. Today, I’ll go over a variant of this algorithm for children. In general, it’s very similar. The major change is in the volume criterion. In adults, we decided upon an (arbitrary) value of 150cc per three shifts. We chose a time interval of 3 shifts vs 1 day to speed up the process.

Suppose you use the 1 day rule for looking at chest tube output. Typically, this would be evaluated in the morning, and the process of pulling the tube or applying water seal, followed by delayed xrays, could lead to a very late discharge. If the output is checked every shift and the most recent three are summed, the patient could meet criteria later in the day and have the tube pulled in the evening. This would allow for an earlier discharge the following day, shaving 12 hours or more off of the hospital stay. This may not make much of a difference to the hospital (although for busy ones it does), but it’s huge for patient comfort and satisfaction.

Note that the output criterion has been changed to 2cc/kg over three shifts. This adjusts for the varying sizes of the children that we treat. Otherwise things are basically the same.
