Question
• I have a 55 yo patient with Idiopathic
Pulmonary Fibrosis (IPF) who was
intubated due to acute exacerbation,
should he be evaluated for transplant?
• Should he go on Extracorporeal
Mechanical Oxygenation (ECMO)?

Question
• I have a 55 yo patient with Idiopathic
Pulmonary Fibrosis (IPF) who was

• Should he go on Extracorporeal
Mechanical Oxygenation (ECMO)?

Ideal Pre-transplant ECMO
• Has already consented to transplant and
evaluation (is it truly informed consent on
ECMO)?
• Good Pre-ECMO functional status
• Without other relative contraindications (age,
obesity, AMS, social support, drug/tobacco)
• Evaluation complete (e.g. Heart cath,
colonoscopy, etc)
• Not Veno-arterial ECMO by femoral approach
![Page 14: ICU Care of the Lung Transplant Recipient](https://reader031.vdocument.in/reader031/viewer/2022030317/5a65f7347f8b9aaf638b68c1/html5/thumbnails/14.jpg)
When and Why to do ECMO
• End stage Lung failure not supported by
conventional support
• Patient cannot maintain muscular conditioning
due to dysfunctional gas exchange
• When ECMO and its complications are superior
to prolonged mechanical ventilation (e.g.
tracheostomy and feeding tube for cystic fibrosis)
• After evaluation complete or to allow
consent/evaluation

Moral of the story
• Ideally, send us your patients early as outpatient
• Send us your inpatient transplant candidates
early (i.e. before intubation)
• If intubated, please send potential candidates
early to avoid critical care myopathy
• ARDS is not usually a transplant diagnosis, but
some have transplanted prolonged ARDS1

Planned post-operative ECMO
• Used in pulmonary hypertension (de-
conditioned left ventricle)1,2
• Often employed when single lung
implanted in a patient with pre-operative or
intraoperative pulmonary hypertension
• Always Veno-arterial to prevent excess
flow to lung(s)

Ventilation
• 6cc/kg ideal body weight (IBW) used

• Most wean FIO2 over PEEP

Lung Transplant in the Community
• Common ICU presentations
• Respiratory Failure
• Non-pulmonary surgical needs
• Shock, usually septic
• Acute renal failure
• Altered mental status
• Diverticulitis/Appendicitis
.

Lung Transplant in the Community• What do I do if I admit a lung transplant
patient at 2 am?
• Don’t worry too much about treating for
rejection, this requires biopsy and
exclusion of infection
• Ok to hold or continue cell cycle inhibitor
(Mycophenolate (MMF) or azathioprine
(AZA)
• Usually held if infection is suspected
• Not really a big deal either way for 1 dose
![Page 41: ICU Care of the Lung Transplant Recipient](https://reader031.vdocument.in/reader031/viewer/2022030317/5a65f7347f8b9aaf638b68c1/html5/thumbnails/41.jpg)
Lung Transplant in the Community• Start stress dose steroids if in shock
• If intubated, do a BAL for bacterial,
fungal, AFB, viral, galactomannen, PJP
• Presumptive antibiotics are OK
• Usually vancomycin/Zosyn/azithro
• If respiratory failure same abx plus
antifungal (Cancidis or voriconazole)
• Tamiflu if flu season
• If vori added, decreased CNI by 50%.

Lung Transplant in the Community
• tacrolimus/cyclosporine and steroids

Acutely elevated Cr
• Usually hypovolemia +/- supratheraputic
calcineurin inhibitor (tacro or cyclosporine)
• check 10 hour level, if more than 10 hours
since last dose OK to check “random

• Hold CNI until level returns
• Gentle hydration
• Know baseline Cr if able, CKD is
common!
