Challenging case #PedsICU #PedsCICU
Newborn w/ CHD, with mBTT shunt for pulm BF
low BP
wide PP
bradycardia with ST changes that led to a near arrest
mBTT shunt banded and the infant recovered

2/6
Fairly remote from surgery but still in ICU, had
acute severe desaturation
hypotension
low EtCO2

Progressed to eCPR with neck VA ECMO cannulation

3/6
Quick recovery with excellent hemodynamics/saturations/pulm mechanics on ECMO. Low flow trial 2/2 oxygenator failure still with excellent hemodynamics. Exchanged circuit.
Went to cath lab to evaluate shunt
quite narrowed but not occluded

Question 1:
4/6
Shunt stented, expected to come off but on return to ICU
hypotensive
labile
bloody ETT secretions
Question 2:
Shunt stented, expected to come off but on return to ICU



Question 2:
5/6
Increased ECMO flow and vasoactives
more hypotensive
worse bloody ETT 
frank pulmonary hemorrhage
APRV
inhaled TXA
Turned ECMO flow way down
minimized anticoagulation
pulmonary hemorrhage and hypotension significantly improved
Increased ECMO flow and vasoactives









6/6
Moral:
When cannulated via the neck, arterial cannula can be directed right toward an mBTT shunt; esp. if less restrictive
torrential pulmonary blood flow
pulmonary hemorrhage
hypotension
ECMO flow is no longer helpful and it is imperative to come off ASAP
