OBJECTIVE This study aimed to compare the effects of two different perfusion techniques: conventional cardiopulmonary bypass and miniature cardiopulmonary bypass in patients undergoing cardiac surgery at the University Hospital of Santa Maria--RS. METHODS We perform a retrospective, cross-sectional study, based on data collected from the patients operated between 2010 and 2013. We analyzed th...

OBJECTIVE A multipronged approach to improve vital organ perfusion during cardiopulmonary resuscitation that includes sodium nitroprusside, active compression-decompression cardiopulmonary resuscitation, an impedance threshold device, and abdominal pressure (sodium nitroprusside-enhanced cardiopulmonary resuscitation) has been recently shown to increase coronary and cerebral perfusion pressures...

Many epidemiologic reports associate ambient levels of particulate matter (PM) with human mortality and morbidity, particularly in people with preexisting cardiopulmonary disease (e.g., chronic obstructive pulmonary disease, infection, asthma). Because much ambient PM is derived from combustion sources, we tested the hypothesis that the health effects of PM arise from anthropogenic PM that cont...

BACKGROUND Commonly used cardiopulmonary bypass systems with cardiotomy reservoir, oxygenator, and roller pump require preoperative crystalloid filling. Radical reduction of the filling fluid volume and replacing it with the patient's own blood has a fundamental impact on the outcome. AIM A comparison of cardiopulmonary bypass filled with the patient's blood, applied in Poland for the first t...

conclusions no significant difference in reducing post bypass inflammation between preoperative steroid treatment and combined preoperative and intraoperative steroid administration reported and they had the same effects. results in both groups, no significant difference with variation of expression for il-6 (inflammatory factor) and il-10 (anti-inflammatory factor) in different times after byp...

the present study was undertaken to compare the in hospital results of coronary artery bypass graft (cabg) with (on pump) or without (off pump) cardiopulmonary bypass (cpb). data were collected on all first-time isolated cabgs with saphenous vein and/or artery grafts at shahid madani hospital in tabriz-iran, between 2006 and 2009. age and clinical profile were marched between on pump and off pu...

The protein C system is an important anti thrombotic pathway that regulates the coagulation system by inactivating procoagulant factors Va and VIlla and enhancing clot lysis by inhibiting the activity of plasminogen activator inhibitor. Protein C deficiency, therefore, is a hypercoaguable state characterized by increased risk of thromboembolic events such as stroke, pulmonary embolism, and veno...
