Abstract:
Background Computer enabled robotic mitral valve repair cases have longer cross-clamp and perfusion times because of the more technically difficult procedure. To modify some of the well-documented side effects of standard cardiopulmonary bypass (CPB), we used a new mini-circuit on three robotic mitral cases. Methods Three patients having mitral valve repair (triangular resection of P2 and annuloplasty ring) using the daVinci Robot (Intuitive Surgical, Sunnyvale, CA) had circulatory support using a modified Resting Heart System (Medtronic, Inc., Fridley, MN), a vertically oriented space saving

Abstract:
Although many refinements in perfusion methodology and devices have been made, extracorporeal circulation remains a contributor to neurological complications, bleeding coagulopathies, use of blood products, as well as systemic inflammatory response. With the exposure of these adverse effects of cardiopulmonary bypass, the necessity to re-examine the safety of extracorporeal circuits is vital. A failure mode effect analysis (FMEA) is a proven proactive technique developed to evaluate system effect or equipment failure. FMEA was used to evaluate the six different types of extracorporeal circuits

Abstract:
One of the most challenging applications of cardiopulmonary bypass is corrective cardiac surgery in the neonate. The small size and high metabolic demand of these patients require miniaturized but efficient equipment. Even with the most advanced components, the volume required to prime the perfusion circuit is typically more than twice the blood volume of a neonate. Neonates have limited cardiac and pulmonary reserves and, therefore, great care is required to preserve those organs that have often already been subjected to hypoxemia, congestive heart failure, or low cardiac output prior to surg

Abstract:
AbstractPriming the cardiopulmonary bypass (CPB) circuit without the addition of homologous blood constitutes the basis of blood-saving strategies in open-heart surgery. For low-weight patients, in particular neonates and infants, this implies avoidance of excessive hemodilution during extracorporeal circulation. The circuit has to be miniaturized and tubing must be cut as short as possible to reduce the priming volume to prevent unacceptable hemodilution with initiating CPB. During perfusion, measures should be taken to prevent blood loss from the primary circuit to avoid replacement by addit

Objective: To evaluate the effect of a miniaturized extracorporeal circulation system (MECC™System) compared to conventional extracorporeal circulation (ECC) regarding liver function in cardiac surgical patients. Methods: Double indicator dilution measurements were achieved by bolus injection of indocyanine green (ICG) for assessment of cardiac index (CI) and plasma disappearance rate of ICG (PDRig). Measurements were simultaneously performed preoperatively after induction of anaesthesia (T1), following admission on the ICU (T2) and 6 h postoperatively (T3). Results: CI and PDRig were markedly

Abstract:
The 1/2″ venous line has long been the drainage tubing diameter of choice for adult patients undergoing cardiac surgery. However, several programs use a smaller diameter venous line when used in conjunction with kinetic-assisted venous drainage or vacuum-assisted venous drainage. In 2014, our perfusion team made an institution-wide effort to miniaturize the cardiopulmonary bypass (CPB) circuit for children. One of our changes was the transition to a 3/8″ diameter venous line for drainage, even in our larger patients (up to 80 kg). We reviewed the current literature on this topic and delineated

Abstract:
Electrical impedance spectroscopy (EIS) is widely recognized as a powerful tool in biomedical research. For example, it allows detection and monitoring of diseases, measuring of cell density in bioreactors, and characterizing the permeability of tight junctions in barrier-forming tissue models. However, with single-channel measurement systems, only integral information is obtained without spatial resolution. Here we present a low-cost multichannel impedance measurement set-up capable of mapping cell distributions in a fluidic environment by using a microelectrode array (MEA) realized in 4-leve

Abstract:
Following a succession of changes in circuitry and priming additives between 1993 and 1998, a comprehensive re-evaluation of neonatal cardiopulmonary bypass (CPB) practice was undertaken. Samples from 10 infants (Group 1) undergoing CPB were evaluated for osmolality, oncotic pressure, total protein, hematocrit, glucose, and electrolytes (Na+, K+, iCa2+). These samples were tested at six measurement points: (1) after priming, (2) patient pre-CPB, (3) CPB-start, (4) CPB-mid, (5) CPB-end, and (6) post-modified ultrafiltration (MUF). Prime volumes were also carefully measured as well as the type a

Abstract:
La circolazione extracorporea convenzionale (cCEC) è un trigger per una risposta infiammatoria sistemica cosí come per l´emodiluizione, coagulopatie e disfunzione d´organo. La circolazione extracorporea miniaturizzata (MECC) ha il potenziale vantaggio di ridurre questi effetti deleteri. I dubbi sulla sua sicurezza sono stati uno dei principali motivi che hanno impedito la sua accettazione e la sua diffusione persino nei grandi centri dove il suo uso è limitato agli interventi di bypass aortocoronarico (CABG). Dopo una larga esperienza nella MECC abbiamo apportato delle modifiche tali da fugar
