BACKGROUND: The mechanisms of acid-base changes during cardiopulmonary bypass (CPB) remain unclear. We tested the hypothesis that, when used as CPB pump prime solutions, Plasma-Lyte 148 (PL) and Hartmann's solution (HS) have differential mechanisms of action in their contribution to acid-base changes. METHODS: We performed a prospective, double-blind, randomized trial in adult patients undergoing elective cardiac surgery with CPB. Participants received a CPB prime solution of 2000 mL, with either PL or HS...

INTRODUCTION: Cardiopulmonary resuscitation restores circulation, but with inconsistent blood-flow and pressures. Our recent approach using an extracorporeal life support system, named "controlled integrated resuscitation device" (CIRD), may lead to improved survival and neurological recovery after cardiac arrest (CA). The basic idea is to provide a reperfusion tailored to the individual patient by control of the conditions of reperfusion and the composition of the reperfusate. Hypothermia is one aspect of this concept...

INTRODUCTION: Mycobacterium chimaera ( M. chimaera) is a recently characterised bacterium that can cause life-threatening infections in small numbers of patients who undergo cardiopulmonary bypass during cardiac surgery. The likely mode of transmission is thought to occur through aerosolisation from contaminated water reservoirs. The airborne bacteria then contaminate the surgical field, leading to an infection months or even years later. The preferred practical solution to disrupt the transmission of these airborne bacteria to the patient is to remove the heater-cooler units (HCUs) from the operating room (OR)...

INTRODUCTION: Aortic arch reconstruction under moderate hypothermia is commonly performed with antegrade cerebral perfusion (ACP) for brain protection; however, hypothermia alone is often solely relied upon for visceral and lower body protection. We investigated whether the addition of simultaneous lower body perfusion to ACP (whole body perfusion - WBP) may ameliorate the metabolic derangements of moderate hypothermic circulatory arrest (MHCA). METHODS: Between 2008 and 2014, 106 consecutive patients underwent elective or emergent aortic arch surgery with MHCA, with either ACP only (44 patients, 66±12 years, 30% female) or WBP (62 patients, 61±15 years, 31% female)...

INTRODUCTION: Commercial membrane lungs are designed to transfer a specific amount of oxygen per unit of venous blood flow. Membrane lungs are much more efficient at removing CO2 than adding oxygen, but the range of CO2 transfer is rarely reported. METHODS: Commercial membrane lungs were studied with the goal of evaluating CO2 removal capacity. CO2 removal was measured in 4 commercial membrane lungs under standardized conditions. CONCLUSION: CO2 clearance can be greater than 4 times that of oxygen at a given blood flow when the gas to blood flow ratio is elevated to 4:1 or 8:1...

OBJECTIVE: The present study was been designed to investigate the role and pharmacological potential of hedgehog in oestrogen-deficient rat heart. METHODS: Oestrogen deficiency was produced in female Wistar rats by the surgical removal of both ovaries and these animals were used four weeks later. Isolated rat heart was subjected to 30 min ischaemia followed by 120 min of reperfusion (I/R). The heart was subjected to pharmacological preconditioning with the hedgehog agonist purmorphamine (1μM) and GDC-0449, a hedgehog antagonist, in the last episode of reperfusion before I/R...

INTRODUCTION: Bispectral index (BIS) and monitoring of end-tidal concentration may be associated with a reduction in the incidence of awareness during volatile-based general anaesthesia. An analogue of end-tidal concentration during cardiopulmonary bypass (CPB) is measuring exhausted isoflurane concentration from the oxygenator as an estimate to blood and, so, brain concentration. The aim of this study was to determine the relationships between oxygenator exhaust and blood concentrations of isoflurane and the BIS score during CPB when administering isoflurane into the sweep gas supply to the oxygenator...

BACKGROUND: Cardiac surgery on Jehovah's Witnesses (JW) can be challenging, given the desire to avoid blood products. Establishment of a blood conservation program involving the pre-, intra- and post-operative stages for all patients may lead to a minimized need for blood transfusion in all patients. METHODS: Pre-operatively, all JW patients were treated with high dose erythropoietin 500 IU/kg twice a week. JW patients were compared to matching non-JW patients from the congenital cardiac database, two per JW to serve as control...

BACKGROUND: Modified ultrafiltration (MUF) can be performed in infants with ventricular septal defects (VSDs) after cardiopulmonary bypass (CPB) to reduce haemodilution and its potential adverse effects. High-flow MUF might reduce ultrafiltration duration and hasten the necessary correction of haemodilution during CPB. However, its influence on brain oxygenation remains controversial. OBJECTIVE: This non-randomized, prospective, pilot study aimed to investigate the influence of high-flow MUF on brain oxygenation in infants with VSDs...

The intra-aortic balloon pump (IABP) has been the most commonly used mechanical circulatory support device for nearly five decades. In theory, the IABP can increase the blood and oxygen supply of the coronary artery by increasing the diastolic pressure in the aortic root when the balloon is inflated and reduce left ventricular afterload by rapidly deflating the balloon during the systolic phase. Therefore, some researchers put forward the idea of preoperative prophylactic use of an IABP, which has been frequently performed in high-risk patients undergoing elective percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery (CABG)...

INTRODUCTION: Residual pump blood from the cardiopulmonary bypass (CPB) circuit is often collected into an infusion bag (IB) and re-transfused. An alternative is to chase the residual blood into the circulation through the arterial cannula with Ringer's acetate. Our aim was to assess possible differences in hemostatic blood quality between these two techniques. METHODS: Forty adult patients undergoing elective coronary artery bypass graft surgery with CPB were randomized to receive the residual pump blood by either an IB or through the Ringer's chase (RC) technique...

OBJECTIVE: The postoperative systemic inflammatory response after cardiopulmonary bypass (CPB) is still an undesirable side-effect after cardiac surgery. It is most likely caused by blood contact with foreign surfaces and by the surgical trauma itself. However, the recirculation of activated shed mediastinal blood is another main cause of blood cell activation and cytokine release. Minimal invasive extracorporeal circulation (MiECC) comprises a completely closed circuit, coated surfaces and the separation of suction blood...

INTRODUCTION: Current methods of teaching endovascular aortic aneurysm repair (EVAR) planning involve non-criteria-based observations that lack validity. The primary aim of this study was to validate an EVAR Planning Objective Structured Assessment of Skill (EpOSAS) tool for the assessment of pre-operative EVAR planning skills. METHODS: Content analysis was performed in order to inform the formulation of EpOSAS domains. Thirty-five participants planned two cases of infra-renal abdominal aortic aneurysm for EVAR, using the OsiriX 7 platform...
