Central venous-to-arterial CO2 difference as a biomarker of outcome in children who underwent surgery for congenital heart disease

Abstract Background: In congenital heart surgery, low cardiac output syndrome (LCOS) is a major cause of morbidity in the immediate post-operative period. A decrease in cardiac output leads to an increase..

Analysis of P(v-a)CO2/C(a-v)O2 Ratio and Other Perfusion Markers in a Population of 98 Pediatric Patients Undergoing Cardiac Surgery

Abstract Background:   The so-called Low Cardiac Output Syndrome (LCOS) is one of the most common complications in pediatric patients with congenital heart disease undergoing corrective surgery. LCOS requires high..

Efficacy and safety of carbon dioxide insufflation for brain protection for patients undergoing planned left-sided open heart valve surgery: protocol…

Abstract Introduction Brain injury is common following open heart valve surgery. Carbon dioxide insufflation (CDI) has been proposed to reduce the incidence of brain injury by reducing the number of air..

Continuous field flooding versus final one-shot CO2 insufflation in minimally invasive mitral valve repair

Abstract Background Insufflation of carbon dioxide (CO2) into the operative field to prevent cerebral or myocardial damage by air embolism is a well known strategy in open-heart surgery. However, here..

Physiology of extracorporeal CO2 removal

Abstract Extracorporeal CO2 removal (ECCO2R) was introduced in 1977 to control arterial CO2 tension and reduce ven- tilation, thus allowing lung rest in patients with acute respiratory failure (ARF). Its..

Comparison of venous pCO2 and exhaust pCO2 for calculating CO2 production during cardiopulmonary bypass

Abstract Introduction Carbon dioxide production (VCO2i), oxygen consumption and oxygen delivery can be monitored during cardiopulmonary bypass (CPB) as markers for tissue perfusion. This study examines if inline venous pCO2..

Warm humidified CO2 insufflation improves pericardial integrity for cardiac surgery: a randomized control study

Abstract BACKGROUND: Flooding the surgical field with dry cold CO2 during open-chamber cardiac surgery has been used to mitigate air entrainment into the systemic circulation. However, exposing epithelial surfaces to cold,..

Measurement of gaseous microemboli in the prime before the initiation of cardiopulmonary bypass

Abstract Introduction: The use of cardiopulmonary bypass is associated with a risk of neurocognitive deficit caused by gaseous microemboli. Flushing the empty bypass circuit with carbon dioxide, which is more..

Extracorporeal gas exchange: when to start and how to end?

Introduction In the last decade, primarily following the H1N1 pandemics [], the extracorporeal respiratory assist is increasingly used [, ]. The acronym “ECMO”, i.e., ExtraCorporeal Membrane Oxygenation, is, however, somehow misleading..

Validation of Transcutaneous Carbon Dioxide Monitoring Using an Artificial Lung During Adult Pulsatile Cardiopulmonary Bypass

Abstract Measurements of transcutaneous carbon dioxide (tcCO2) have been used in multiple venues, such as during procedures utilizing jet ventilation, hyperbaric oxygen therapy, as well as both the adult and..
