Randomized Controlled Trial Clinical TrialTime to tracheal extubation after coronary artery surgery with isoflurane, sevoflurane, or target-controlled propofol anesthesia: a prospective, randomized, controlled trial.
To determine if anesthesia with sevoflurane or target-controlled propofol reduced the time to tracheal extubation after coronary artery bypass graft surgery compared with isoflurane anesthesia. ⋯ The median time to tracheal extubation was significantly longer for the target-controlled propofol group. A significantly greater number in this group required the use of a vasodilator to control intraoperative hypertension.

Comparative Study Clinical TrialArterial versus venous sampling for activated coagulation time measurements during cardiac surgery: a comparative study.
Activated coagulation times (ACTs) are widely used for monitoring anticoagulation during cardiac surgery. Significant variability of this test is well known. Variability in test results was studied, which may arise from the sample drawing site. ⋯ During the period of systemic anticoagulation, there is great individual variability between ACT measures obtained from venous and arterial samples. Further studies are required to analyze the cause of differences at the baseline and the source of variable coagulation times after heparin.

Clinical TrialMidlatency auditory-evoked potentials in the assessment of sedation in cardiac surgery patients.
Midlatency auditory-evoked potentials (MLAEPs) may provide an objective measure of depth of sedation. The aim of this study was to evaluate MLAEPs for measuring sedation in cardiac surgery patients. ⋯ MLAEP latencies can reflect subtle changes in auditory perception, while amplitudes seem to change with transition between deep levels of sedation.

Transcranial Doppler emboli count predicts rise in creatinine after coronary artery bypass graft surgery.
To examine the correlation between transcranial Doppler ultrasonography-detected emboli during coronary artery bypass graft surgery with cardiopulmonary bypass and renal dysfunction as determined by the postoperative change in creatinine. ⋯ Increased numbers of Doppler-detected emboli during coronary artery bypass graft surgery are associated with postoperative renal dysfunction.
