I believe the controversy is the common belief that it should work...as everyone (including myself) believe...hoever desproved by data.
I had a patient today with a thoracoabdominal incision crossing the thorax and abdomen....one lung vent for 3 hours...for a tumor resection that crossed the diaphragm....
I put the epidural in post op....night and day difference....10/10 pain before, no pain afterwards....but the data would suggest that CT graded atelectasis would be no different.
This is where I have a problem with "studies". I mean, gimme a break, Mil. I think it should make a difference. MilMD, Mr. Dude that has so many degrees we should call him
thermometer thinks it should make a difference. Then the "literature" puts out a cuppla "well done" studies, and,
thats that . The
scientific method has been proven and replicated.
I wish I had the statistical prowess to dissect these studies that have "proven" something that, anecdotally, myself, and many other clinicians find the end-result
hard to believe.
I've done hundreds of thoracic epidurals for thoracotomies, as has every other cutting-edge clinician who has been in the anesthesia biz for ten years. No big feat. Just a factor of time. We've seen the clinical differences in our patients...those that cant have an epidural for a thoracotomy for whatever reason, and those that we place them in. No comparison, as Mil pointed out in his recent case. I differ NONE in Mil's description of a thoracotomy patient with a pain score of 10/10 before-epidural, and no-pain/10 post-epidural. With a well placed catheter by a skilled clinician, those are the facts.
Then factor in your knowledge of respiratory physiology, the advantages of being able to breathe "normally" after a surgeon cuts your ribcage open, verses "not being able to breathe normally after a surgeon cuts your ribcage open", i.e...without a thoracic epidural.
I again digress back to your run-of-the-mill patient with multiple rib fractures in the ER, S/P MVA...one of the significant worries about this dude is that he's not gonna respire normally because of the pain, and resultant of that, he is at risk of atelectasis and potential pulmonary consolidation.
Said ER dude differs little from a post-op thoracotomy patient. Suggested pulmonary sequelae are the same.
SO MIL, are these studies GOOD enough to establish a precedence? Good enough to defer the perioperative placement of a thoracic epidural, which you, me, and many other clinicians have witnessed, albeit anecdotally, the clinical advantages of??
Lemme divulge my statistical knowledge and see if I can find, along with you, any weaknesses in said studies...lets be the devil's advocates here...
are they multi-center studies? Are their
n values big enough to warrant clinical precedence? Are their
p values low enough to warrant clinical precedence?
I think this is where the money is...if the n value is high enough, and the p value is low enough,
for clinicians who practice every day to alter their clinical practice because of the results of said study.
Can you say, with confidence, that we should alter our clinical practice because of said studies???
