Live from the OR

Once upon a time I did a post composed of live blogging from the ER. I thought I would replicate the concept tonight by giving you an idea of what a transplant case looks like for me.

11:07 - consent is obtained and I receive an email. I am now aware that a donor liver is expected to arrive for a patient and the surgery should occur sometime today.

17:48 - I find out the donor liver is not expected to arrive until after 10pm, that means an overnight surgery is likely.

21:11 - I call the main OR desk and they indicate a lines-in time of 11:30pm. That means the incision won't happen before 00:30am.

23:50 - I arrive at the hospital to change into clean scrubs, prep some dry ice for samples and start the paperwork.

00:18 - I head down to the OR to check on the progress. They are just finishing the echo and still have to place the radial line.

00:37 - Incision. I draw two purple tops and collect 10cc of urine. I leave the OR and head to the lab to centrifuge the samples and put them on dry ice.

01:26 - Back in the OR to observe

02:51 - Anhepatic phase begins. This is when the patient is no longer connected to his old liver and not yet connected to the new one. I draw samples and put them on ice to process later.

03:29 - Reperfusion. This is when the new liver is connected and circulation through the liver is restored. All the preservatives and biochemical waste from the new liver cause the patients heart to struggle briefly. When well-managed and with a little luck this can be short-lived and uneventful. Tonight, reperfusion goes smoothly.

03:59 - I draw samples and bring them and the pre-reperfusion samples up to the lab to process. Sometimes I stay in the OR until close, but tonight I'm hoping to catch a few hours sleep before class. If the close is within two hours of my shift ending, I will be able to draw the closing samples and leave. If not, I will have to stay until 2 hours post-op.

04:40 - The surgeons have closed, the operation is complete. This was a very short surgery, which is good for the patient, but bad for me. I now have to stay until 6:40 to do the 2 hour post-op samples.

04:50 - Follow the patient up to the SICU to get immediate post-op samples. Run back to the lab to finish processing samples already collected.

05:30 - Email an update about the surgery and schedule for post-operative draws through POD4 to the research group.

06:30 - Head over to the SICU to check in with the nurse and get the 2 hour draw.

06:45 - Head back to the lab to leave the samples on ice (the girl coming in at 7 will process it), head home to catch a three hour nap before class at 11.

Neonatal pre-op MRIs

One of the research studies I am involved in at the hospital includes performing an MRI immediately prior to the heart repair surgery of TGA and HLHS babies*. The baby we studied yesterday was oversized (due to mom's diabetes), but otherwise stable. The MRI revealed PVL,** which we have seen in 20% of patients prior to their surgery, and also a temporal lobe hemorrhage. We immediately called the surgeon to the MRI suite and a discussion ensued: what is the bigger danger - delaying the heart repair or potentially enlarging the bleed (the surgery would involved heparin, a blood thinner)?

We decided to delay the surgery and re-image the child in a few days to re-evaluate.

Sitting in on that discussion reminded me why I want to be a doctor. I've been losing the faith a bit with all the paperwork that is my job recently and this year long illogical waiting game of frustration that is applying. It was nice to have a reminder; hopefully I will get another one this Friday in clinic.

*TGA = Transposition of the great arteries. The aorta is connected to the right ventricle and the pulmonary artery is connected to the left ventricle, creating two independent circulations.
HLHS = Hypoplastic left heart syndrome. The left ventricle fails to form and the aorta is small and insufficient. Once the ductus closes, there is no systemic circulation.
**PVL = Periventricular leukomalacia, a white matter injury that occurs in pre-mature babies and is thought to be associated with mild cognitive problems.

Bummer

I had a little abstract prepared to submit to the Pediatric Academic Societies annual meeting (in Hawaii). It's customary to run these things by the Director(s) of the department(s) relevant to the abstract. Well, one of them killed my abstract. He won't let me submit it. Boo. And not because it's bad science, but because he's afraid we'll lose referral business.

I deserve a cookie.



A moment of victorious immodesty: I just cranked out a 115 page IRB protocol for constraint-induced movement therapy in 4.5 days.


update: It was pushed to the October 3rd review. : (
