| Abstract | OBJECTIVE: Although experimental studies have indicated that blood cardioplegia may be superior to crystalloid cardioplegia for myocardial protection, clinical data still remain uncertain. In a previous randomised study from our institution, including 1440 patients undergoing coronary artery bypass grafting (CABG), no beneficial effects of blood cardioplegia were seen in any relevant outcome variables. The investigation was therefore extended to a patient population having longer pump times and ischaemic periods. METHODS: Over a 48-month period, all patients undergoing aortic valve replacement with or without CABG performed by two surgeons, were prospectively randomised to receive either intermittent cold retrograde blood cardioplegia (group B) or intermittent cold retrograde crystalloid cardioplegia (group C) during aortic cross-clamping. RESULTS: A total of 345 patients aged 28-90 years (median, 72 years) entered the study (group B, n=172, group C, n=173). All relevant demographic and operative variables were similar for both groups. As for the clinical course, no statistically significant differences were seen concerning spontaneous sinus rhythm after aortic declamping, use of inotropic drugs, duration of ventilatory support, bleeding and rate of allogeneic blood transfusions, perioperative myocardial infarction, episodes of atrial fibrillation, stroke or minor neurological dysfunction, renal function, infections, physical rehabilitation or mortality. Further, in the patients with the longest ischaemic times, no statistically significant differences between the groups could be demonstrated. CONCLUSIONS: There were no indications that retrograde cold blood cardioplegia was superior to retrograde cold crystalloid cardioplegia patients undergoing aortic valve replacement, with or without CABG. |

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.
