Randomized Controlled Trial Clinical TrialSimilar pain scores after early and late extubation in heart surgery with cardiopulmonary bypass.
To investigate if early extubation, 2 hours after surgery, would result in more postoperative pain or in an increased use of opioid analgesics compared with late extubation, 6 hours after surgery. ⋯ Early extubation had no negative effect on the quality of postoperative pain control and was not followed by an increased use of analgesics.

Comparative StudyECG changes after CABG: the role of the surgical technique.
The purpose of this study was to determine whether coronary artery bypass grafting (CABG) surgery on the beating heart (BH) is associated with reduction of R-wave potentials on the precordial leads on the surface electrocardiogram (ECG) as previously shown for CABG with cardiopulmonary bypass. ⋯ The findings indicate, for the first time, that CABG surgery on the BH is not followed by any reduction of R-wave amplitude on precordial leads and confirms that the BH technique is associated with a lower release of myocardial cell damage markers.

Cardiac biomarker release after CABG with different surgical techniques.
To investigate the release of cardiac biomarkers (troponin I and CK-MB) in patients undergoing coronary artery bypass graft (CABG) with or without cardiopulmonary bypass (CPB). ⋯ Cardiac troponin I release after multivessel CABG is associated with the technique. Different values for the normal range should be considered. OPCABG is minimally invasive for the heart as far as myocardial marker release is concerned.

Comparative StudyNoninvasive measurement of intrapulmonary shunting.
To investigate the accuracy and precision of a noninvasive approach to measurement of pulmonary shunt fraction using simultaneous application of 2 fundamental respiratory mixing equations: the direct Fick equation for oxygen and the shunt equation of Berggren. This can be performed without mixed venous blood sampling and requires measurement of oxygen uptake and pulmonary blood flow. ⋯ The noninvasive method is an accurate substitute for invasive shunt fraction measurement with mixed venous blood sampling.
