Comparative StudyThe impact of atrio-biventricular pacing on hemodynamics and left ventricular dyssynchrony compared with atrio-right ventricular pacing alone in the postoperative period after cardiac surgery.
The aims of this study were to test the hypotheses that in the postoperative period after coronary artery bypass graft surgery (1) atrio-right ventricular (RA-RV) pacing induces a decrease in cardiac output compared with RA pacing alone and (2) atrio-biventricular (RA-BiV) pacing improves CO compared with RA-RV pacing. ⋯ RA-BiV pacing improves cardiac output compared with RA-RV pacing in the postoperative period after coronary artery bypass graft surgery. This improvement is related to an improvement in left ventricular synchronicity.

Randomized Controlled Trial Comparative StudyThe efficacy of intravenous patient-controlled remifentanil versus morphine anesthesia after coronary artery surgery.
To compare the effect of remifentanil and morphine after coronary artery surgery in a patient-controlled analgesia (PCA) protocol. ⋯ There was no difference in patient satisfaction between the 2 groups. On the basis of the reduction of pain scores (with cough and movement) at 1 or 2 postoperative time points, PCA-remifentanil infusion is a better analgesic technique; overall, both PCA techniques provided for effective pain scores (<3). In patients in whom PCA morphine is contraindicated after CABG surgery, PCA remifentanil is a safe alternative.
