Does donor blood perfusion improve myocardial recovery after heart transplantation?
Perfusion of donor blood improved the ability to wean off bypass after 4 hours of storage. Blood perfusion permitted persistent myocardial metabolism during the ischemic period, which led to improved functional recovery. Harvesting donor blood for subsequent perfusion during prolonged storage may improve the results of orthotopic heart transplantation and allow for more distant procurement of donor organs.
A large percentage of patients performed inhalations incorrectly. We cannot conclude that any given device is superior. The variables related with correct IT were age and level of education. Greater health education efforts are needed to teach patients how to use inhalation systems correctly.
