Comparative Study Clinical TrialComparison of uncalibrated arterial pressure waveform analysis with continuous thermodilution cardiac output measurements in patients undergoing elective off-pump coronary artery bypass surgery.
Monitoring of cardiac output is required during anesthesia for off-pump coronary artery bypass (OPCAB) surgery. Recently, FloTrac, a new device for arterial pressure waveform analysis for cardiac output (APCO) monitoring without external calibration, was developed. The authors have compared APCO with STAT-mode continuous cardiac output (SCCO) in patients undergoing OPCAB surgery. ⋯ Uncalibrated APCO values do not agree with thermodilution SCCO and significantly overestimated the SCCO in patients undergoing OPCAB surgery. Further evaluation is required to verify the clinical acceptance of FloTrac APCO in OPCAB surgery.

Comparative StudyHemodynamic responses to etomidate in pediatric patients with congenital cardiac shunt lesions.
The authors investigated the effects of intravenous etomidate on hemodynamics in children with congenital cardiac shunts. ⋯ Etomidate at 0.3 mg/kg produces very minimal changes in hemodynamic parameters and shunt fraction in children with congenital shunt lesions.

Comparative StudyStroke volume variation as a predictor of fluid responsiveness in patients undergoing one-lung ventilation.
To investigate the ability of stroke volume variation (SVV) calculated by the Vigileo-FloTrac system (Edwards Lifescience, Irvine, CA) to predict fluid responsiveness in patients undergoing one-lung ventilation (OLV). ⋯ The authors found that SVV measured by the Vigileo-FloTrac system was able to predict fluid responsiveness in patients undergoing surgery with OLV with acceptable levels of sensitivity and specificity.

Comparative StudyThe endovascular coronary sinus catheter in minimally invasive mitral and tricuspid valve surgery: a case series.
To determine the safety and efficacy of a standardized approach to the use of an endovascular coronary sinus (CS) catheter during minimally invasive cardiac surgery. ⋯ Endovascular CS catheter insertion can be performed with a high rate of success for positioning and a low complication rate. During positioning, obtaining ventricularization is associated with an increased success rate.
