Lung transplantation, or pulmonary transplantation, is a surgical procedure in which one or both lungs are replaced by lungs from a donor. Donor lungs can be retrieved from a living or deceased donor. A living donor can only donate one lung lobe. With some lung diseases, a recipient may only need to receive a single lung.
The procedure was studied by researchers in Boston utilizing a group of ten young pigs. Five of the pigs underwent removal of 90 percent of the bowel followed by STEP. The other pigs underwent the bowel resection without the STEP procedure, serving as control subjects. STEP was shown to lengthen the bowel from 105.2 ± 7.7 cm to 152.2 ± 8.3 cm ...
The blood pump is then switched off, and the interval of circulatory arrest begins. At this time more blood is drained to reduce residual blood pressure if surgery on a cerebral aneurysm is to be performed to help create a bloodless surgical field. [41] After surgery is completed during the period of cold circulatory arrest, these steps are ...
Usually the component returned is the red blood cells, the portion of the blood that takes the longest to replace. Using this method an individual can donate plasma or platelets much more frequently than they can safely donate whole blood. [76] These can be combined, with a donor giving both plasma and platelets in the same donation. [citation ...
In people with a low platelet count, prophylactic platelet transfusions do not need to be given prior to procedures that have a low risk of causing bleeding. [10] [13] [9] Low-risk procedures include surgical sites that do not contain many blood vessels e.g. cataract surgery, [13] or minor procedures.
Aside from the procedure, donating platelets is different from donating blood in a few ways. Firstly, the donor must not take aspirin or other anti-platelet medications such as clopidogrel (Plavix) for anywhere from 36 to 72 hours prior to donation (guidelines vary by blood center). (Aspirin can prevent platelets from adhering to clot bleeding.)
Intraoperative blood salvage (IOS), also known as cell salvage, is a specific type of autologous blood transfusion. Specifically IOS is a medical procedure involving recovering blood lost during surgery and re-infusing it into the patient. It is a major form of autotransfusion.
Autotransfusion is a process wherein a person receives their own blood for a transfusion, instead of banked allogenic (separate-donor) blood.There are two main kinds of autotransfusion: Blood can be autologously "pre-donated" (termed so despite "donation" not typically referring to giving to one's self) before a surgery, or alternatively, it can be collected during and after the surgery using ...
