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 ow 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 ow 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. © 2017 Published by Elsevier Inc.
