Randomized Controlled Trial Clinical TrialInfluence of a new hydroxyethylstarch preparation (HES 130/0.4) on coagulation in cardiac surgical patients.
To compare volume therapy with HES 130/0.4, a new hydroxyethylstarch (HES) solution with a gelatin-based fluid replacement strategy. ⋯ Volume replacement with the new HES preparation was as safe as gelatin-based volume replacement with regard to coagulation in cardiac surgical patients. HES 130/0.4 is an alternative plasma substitute to treat volume deficits.

Comparative Study Clinical TrialTransesophageal echocardiographic evaluation of native aortic valve area: utility of the double-envelope technique.
To assess the accuracy of aortic valve area (AVA) calculations using the continuity equation with data obtained from the double envelope (DE) (simultaneously obtained left ventricular outflow tract [V1]) and aortic valve [V2] velocities) during intraoperative transesophageal echocardiography (TEE). ⋯ TEE evaluation of native AVA using the DE technique is feasible and in good agreement with that obtained by C/TTE and G/CATH. Compared with DE/TEE, PL/TEE did not agree as well. Use of DE/TEE should simplify the continuity equation and may minimize errors resulting from beat-to-beat variability in stroke volume.

Randomized Controlled Trial Clinical TrialTranexamic acid in aortic valve replacement.
To assess the relative efficacy of tranexamic acid compared with a control group to decrease bleeding and transfusion requirements in a uniform population undergoing aortic valve replacement. ⋯ Tranexamic acid reduces postoperative blood loss and transfusion requirements in elective aortic valve replacement.

Randomized Controlled Trial Clinical TrialInfluence of a vital capacity maneuver on pulmonary gas exchange after cardiopulmonary bypass.
To investigate the effect of a single, vital capacity breath (vital capacity maneuver [VCM]), administered at the end of cardiopulmonary bypass (CPB), on pulmonary gas exchange in patients undergoing coronary artery bypass graft surgery. ⋯ The use of a VCM prevented an increase in Q(S)/Q(T) from occurring in the operating room. Although a VCM did not influence pulmonary gas exchange in the ICU, its application in the operating room appears to exert a beneficial effect on tracheal extubation times after cardiac surgery.

Randomized Controlled Trial Comparative Study Clinical TrialPain relief after esophagectomy: Thoracic epidural analgesia is better than parenteral opioids.
To compare postoperative pain relief and pulmonary function in patients after thoracoabdominal esophagectomy treated by continuing perioperative thoracic epidural anesthesia or changing to parenteral opioids. ⋯ Continuation of intraoperative thoracic epidural anesthesia for 5 postoperative days provides better pain relief at mobilization compared with a switch to patient-controlled analgesia with intravenous morphine. There was no intergroup difference in the impact on measures of pulmonary function.
