| Abstract | BACKGROUND: Antifibrinolytic drugs including aprotinin and tranexamic acid are currently used in cardiac surgery to reduce postoperative bleeding and transfusion requirements, and may have different effects on platelets. We therefore evaluated platelet function after cardiopulmonary bypass (CPB) and cardiac surgery to determine the effect of either aprotinin or tranexamic acid. METHODS: In a prospective, randomized study, 50 patients scheduled for elective cardiac surgery with CPB were evaluated. Patients received high-dose aprotinin (n = 25) or tranexamic acid (n = 25) as antifibrinolytic drugs. Coagulation and platelet function were assessed preoperatively, after CPB, 3 and 24 h after surgery using modified thrombelastography and whole blood aggregometry. RESULTS: Impaired coagulation after CPB occurred in both groups compared with preoperative data (P < 0.01). In contrast to modified thrombelastography, thrombin receptor-mediated aggregometry after CPB was significantly decreased only in those patients receiving tranexamic acid until the end of the study period in comparison to the aprotinin group (P < 0.05). Aprotinin-treated patients showed significantly less chest tube drainage (575 mL +/- 228 vs 1033 mL +/- 647, P < 0.05) and need for postoperative transfusion requirements (P < 0.01) compared with the tranexamic acid group. CONCLUSIONS: Platelet function measured by whole blood aggregometry is better preserved by aprotinin than tranexamic acid and may be responsible for producing less bleeding within the first 24 h after CPB. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
