The first indigenous Membrane Oxygenator designed and developed at our Institute was successfully used in 25 patients undergoing various types of open heart procedures. The device performed well in terms of gas exchange and heat transfer at blood flow rates varying from 2 to 5 LPM. We compared the performance with an equal number of oxygenators used in standard practice.

The simple delivery systems which have been used in our centre are disposable blood Spictra cardioplegia delivery system, pressure bag crystalloid cardioplegia delivery system and calioferic cardioplegic technic. The Spictra CPD system has come out recently with an indigenous CPD system. In this system we achieved maximum cooling efficiency, mixing of blood crystalloid and free fall effect…”

The straight shoot (Spictra) system was used in 315 patients as against 1139 imported BCD systems. We find that the efficiency of delivery, cooling, rewarming and precision were good with our indigenously available system, as compared to the imported ones like Shiler BCD, Myotherm and Gish.”

We compiled ACT values after standard heparinisation dose at constant time after initiation of CPB HB & PCV values on Bypass, priming volume, missed venous oxygen saturation, platelet count intra of postup 4 days after surgery, plasma free Hb, Hamaturia, P.O. blood requirements and post OP values of urea, creatinine and bilirubin are presented. These values were compared with other oxygenators and we found that there was no stastically significant difference in both groups in the above parameters.” “…out of 250 cases we performed, we used Spictra Oxygenators in 125 cases in a randomized manner in patients with varying degree of LV dysfunction.”
