Randomized Controlled Trial Clinical TrialEffects of phentolamine on tissue perfusion in pediatric cardiac surgery.
To evaluate whether the deleterious effects of cardiopulmonary bypass (CPB) can be overcome by phentolamine-induced pharmacologic vasodilation in pediatric patients with congenital heart disease. ⋯ The results suggest that the use of phentolamine during CPB is associated with limited systemic anaerobic metabolism and more uniform body perfusion.

Randomized Controlled Trial Comparative Study Clinical TrialDoes high-dose methylprednisolone in aprotinin-treated patients attenuate the systemic inflammatory response during coronary artery bypass grafting procedures?
To discover the possible effects of methylprednisolone on the systemic inflammatory response during aprotinin treatment. ⋯ The use of methylprednisolone attenuates the systemic inflammatory response during aprotinin treatment and improves clinical outcome parameters.

Randomized Controlled Trial Comparative Study Clinical TrialCross-sectional area of the right and left internal jugular veins.
To compare the cross-sectional area (CSA) of the right internal jugular vein (RIJV) with the left internal jugular vein (LIJV) using two-dimensional ultrasound and to measure the response to the Valsalva maneuver in both the supine and Trendelenburg positions. ⋯ The findings suggest that in one third of adults (34%), the LIJV is significantly smaller compared with the RIJV and, combined with operator inexperience, may influence the success rate and risk for complications. Thus, the use of ultrasound and maneuvers that increase CSA is suggested during LIJV cannulation.

Analysis of factors related to jugular venous oxygen saturation during cardiopulmonary bypass.
To investigate preoperative clinical conditions and/or intraoperative physiologic variables related to jugular venous oxygen saturation (SjO2) during cardiopulmonary bypass (CPB). ⋯ During rewarming, when cerebral perfusion and oxygen demand change abruptly, but not during stable hypothermic CPB, CPP was a significant factor related to sjO2.
