Available online xxxx Purpose: Sedation in extracorporeal membrane oxygenation (ECMO) is challenging. Patients require deep seda-
tion because of extremely high respiratory rates and increased work of breathing (“Drowning Syndrome”)
resulting in altered intra-thoracic pressure and reduced pump flow associated with hemodynamic compromise
and decreased oxygenation. However, deep sedation impedes essential active rehabilitation with physical ther-
apy.
Methods: We reviewed data on 3 ECMO patients for whom we used a novel approach to replace continuous drips
with periodic sedation/paralysis. Initially our patients were on high dose narcotics, propofol, and
dexmedetomidine and unable to interact and breathe comfortably. IV narcotics were weaned over 24 h and
were replaced by methadone. Dexmedetomidine was continued in order to block hyperadrenergic events.
Propofol was weaned at a prescribed rate. When patients demonstrated agitation, decreased pump flow and he-
modynamic compromise, diazepam was given in combination with a paralytic.
Results: By replacing IV narcotic and propofol, with PRN diazepam and vecuronium, patients were off continuous
drips in 1 week and were able to actively participate in physical therapy.
Conclusion: Allowing patients to wake up by rapid weaning of continuous narcotics and anesthetic agents using
Dexmedetomidine and periodic paralysis to favorably alter hemodynamics is a successful method to wean deep
sedation in ECMO.
