Preoperative very short-term, high-dose erythropoietin administration diminishes blood transfusion rate in off-pump coronary artery bypass: A randomized blind controlled study
ABSTRACT Human recombinant erythropoietin has been used to obtain a rapid increase in red blood cells before surgery. Previously, the shortest preparatory interval has been 4 days, but at the European Hospital only 2.4 days on average separate hospitalization and surgery. We therefore proposed a randomized blind trial to test the efficacy of high-dose erythropoietin for very short-term administration.
All patients presenting with a diagnosis of isolated coronary vessel disease were randomized to either erythropoietin therapy or a control group. Patients with a creatinine level greater than 2 mg/dL or hemoglobin level greater than 14.5 g/dL were excluded. Hemoglobin values were collected preoperatively and on postoperative days 1 and 4. Blood loss and blood transfusion rate were recorded at the time of discharge.
We enrolled 320 consecutive patients in the study. No significant difference was found in preoperative parameters, postoperative blood loss, or mean preoperative hemoglobin levels. On postoperative day 4, mean hemoglobin was 15.5% higher in the erythropoietin group (10.70 +/- 0.72 g/dL vs 9.26 +/- 0.71 g/dL; P < .05). This group required 0.33 units of blood per patient, whereas the controls required 0.76 units per patient (risk ratio 0.43, P = .008).
A significant reduction in transfusion rate and a significant increase in hemoglobin values were observed in the erythropoietin group. No adverse events related to erythropoietin administration were recorded. A very short preoperative erythropoietin administration seems to be a safe and easy method to reduce the need for blood transfusions.

- "The use of erythropoietin is also limited by the necessity of starting its administration 3 weeks before surgery . A short course erythropoietin was also used several days before cardiac operation in anemic patients (haemoglobin < 13 g/dl) without autologous predonation  . In cardiac patients, there are certain contraindications for participation in autologous blood donation programmes; in addition to anaemia (haematocrit below 33%), they include critical aortic stenosis, idiopathic subaortal stenosis, ischaemic heart disease with unstable angina or with left main coronary artery stenosis, chronic NYHA class IV heart failure, ventricular rhythm disturbances on the day of blood collection and an acute heart attack.

Conference Paper: Learning methods in space technology[Show abstract] [Hide abstract]
ABSTRACT: To begin, we must agree on what we mean by a learning system and a learning control system. A system is called learning if the information pertaining to the unknown features of a process or its environment is acquired by the system, and the obtained experience is used for future estimation, recognition, classification, decision or control such that the performance of the system will be improved. A learning system is called a learning control system if the acquired information is used to control a process with unknown features (these standardized definitions are taken from Reference 1). The attribute of "learning" that is associated with learning systems, derives from psychological learning theories, especially reinforcement learning theories.Decision and Control including the 13th Symposium on Adaptive Processes, 1974 IEEE Conference on; 01/1974

ABSTRACT: This paper considers the synthesis of processes comprising batch reaction and distillation tasks. Complex process features, such as material recycles and shared intermediates are taken into account. The problem is formulated as a multistage optimal control problem. A control vector parametrisation approach is utilised to reduce this infinite dimensional dynamic problem to a finite dimensional nonlinear programming problem. An example involving an exothermic reaction step followed by a batch distillation is presented to illustrate the proposed approach.Computers & Chemical Engineering 06/1995; 19(19):167-174.
