AbstractWe report our experience using an originally designed thin walled metal-tipped arterial cannula for neonatal open heart surgery. Its external diameter is 2.1 mm and its internal diameter is 1.7 mm, it has a high internal – external diameter ratio. It was used on 36 patients, who were either neonates or small infants. In 32 of the patients, it was inserted into the ascending aorta for systemic perfusion. In the other 4, it was inserted into the brachiocephalic artery for selective cerebral perfusion during repair of the aortic arch. The relationship between the pressure drop and the bypass flow was obtained for the 7 most recently treated patients. The pressure drop at a bypass flow of 500 ml/min was 150 mmHg. Due to the high internal – external diameter ratio of this cannula, and its excellent flow characteristics, we consider it to be particularly useful in neonatal open heart surgery, while it also allows for successful selective cerebral perfusion during repair of the aortic arch in neonates.

A New Technique

Dr Parafulla Kumar Sen, popularly known as P K Sen was a great Bengali surgeon of Twentieth century. Regarded as the founder of cardiothoracic surgery in India, Dr Sen performed the first intracardiac operation of any kind, the first open heart surgery and also the first heart transplantation in this subcontinent. He also made very significant contribution in the development of transmyocardial revascularization, a new technique for aortic arch replacement and described a group of nonspecific vasculitis. Dr P K Sen was born in Kolkata, the then capital of undivided Bengal in 1915. But he is little known in Bangladesh. This article is an attempt to notify the deeds of this Bengali surgeon.DOI: http://dx.doi.org/10.3329/cardio.v3i2.9200  Cardiovasc. J. 2011; 3(2): 254-257

The Mean

SummaryA prospective study in 13 patients undergoing open-heart surgery with extracorporeal circulation revealed a marked decrease of the mean one-stage prothrombin time activity from 88% to 54% (p <0.005) but lesser decreases of factors I, II, V, VII and X. This apparent discrepancy was due to the appearance of an inhibitor of the extrinsic coagulation system, termed PEC (Protein after Extracorporeal Circulation). The mean plasma PEC level rose from 0.05 U/ml pre-surgery to 0.65 U/ml post-surgery (p <0.0005), and was accompanied by the appearance of additional proteins as evidenced by disc polyacrylamide gel electrophoresis of plasma fractions (p <0.0005). The observed increases of PEC, appearance of abnormal protein bands and concomitant increases of LDH and SGOT suggest that the release of an inhibitor of the coagulation system (similar or identical to PIVKA) may be due to hypoxic liver damage during extracorporeal circulation.

SummaryBlood clotting investigations have been executed in 25 patients who have undergone open heart surgery with extracorporeal circulation. A description of alterations in the activity of blood clotting factors, the fibrinolytic system, prothrombin consumption and platelets during several phases of the operation is given.
