“…13 In the present study, we elected to use intra-aortic balloon pumping (IABP) to generate pulse pressure, given that IABP allows an approximation of physiologic heart rate, stroke volume, and rate of pressure rise (dP/dt). 14 Mulay and associates 15 recommended the use of IABP, because this method is a simple and reliable way to obtain pulsatile flow during CPB.…”

SummaryObjective: Complications arising from roller pump usage in modern heart-lung bypass (HLB) systems are widely known. Alternative to roller pumps has existed as various devices. This work is dedicated to developing new, considerably simpler and less expensive pump device for HLB systems, which provides maximally physiological pulsating blood flow. Material and Method:We used pediatric cardiotomy reservoirs of HLB systems as blood chambers. Two such reservoirs were placed in front of the oxygenator, with their in-flow tubes connected to the venous blood tubes, and the outflow tubes -to the entry to the oxygenator. In each reservoir, 2 air outlets tubes were connected to pneumo-receivers of positive and negative pressure. We filled up one of the reservoirs whith closed of exit blood tube by creating negative pressure in it. Simultaneously, with closed entry blood tube of the second reservoir, we ejected blood from it by created positive pressure. Used external pulsator. Results:In stand testing under re-circulation regime, productivity of the device was 12,5 liters/minute. Pressure on exit blood pump was within 0 to 300mm.Hg. The pump operating system enabled laminar, as well as pulsating flow of liquid, with frequency of 0-200 pulses/minute. Research is based on experiments conducted on 14 mongrel dogs weighing 20 kg. Standard methodology was used to cannulate Venae cavae and aorta, and to connect perfusion system to body. Duration of complete HLB reached 2 hours. Systolic pressure was maintained within 120-130mm.Hg.; diastolic -70-80 mmHg. Velocity of blood flow in the aorta arc fluctuated within 950-1100 ml/min; in the femoral artery -within 60-80 ml/min. Conclusion:Preliminary tests of the new pump indicate that its hemodynamic characteristics are maximally approximated to physiological ones. In comparison to modern machines, a perfusion system with new pump type has minimal volume of fill-up and does not damage formative elements of blood.Keywords: Pulsatille flow, blood pump, perfusion.Please cite this article as: Khodeli N., Shengelia O., Chkhaidze Z., Partsakhashvili D., Sologashvili T.

“…Although this mechanism of arterial air embolism may be rare, the potential for sucking a relatively large volume (up to 40 cc) of room air into the ascending aorta during CPB is real and can be minimized by stopping the IAB when surgical maneuvers require that the aorta be opened. This word of caution should not detract from the message in the excellent letter of Mulay and associates 1…”

“…The recommendation in the recent letter by Mulay and associates 1 to maintain intraaortic balloon (IAB) counterpulsation during the entire period of cardiopulmonary bypass (CPB) should be qualified with a word of caution: cases of significant air embolism have been reported if the aorta is opened (as it is for cannulation) at the onset of IAB deflation. 2,3 In their letter, the authors noted that they temporarily stop the IAB pump when clamping or unclamping the aorta; on the basis of the previously reported cases, we believe the IAB should also be turned off with any aortotomy or when the arterial perfusion or cardioplegia cannulas or vents are being inserted or removed.…”
