Comparative StudyPatients' conscious recollections from cardiac anesthesia.
To estimate the current incidence of conscious recollections from the time of anesthesia, the contribution of anesthetic drugs to this incidence, and the patients' experience of cardiac anesthesia and surgery. ⋯ The incidence of awareness and recall is similar to the incidence reported during general surgery. Cardiac surgery does not carry increased risk of awareness. Benzodiazepines given during anesthesia are effective in decreasing the incidence of recalled awareness, and the experience of awareness is not often particularly traumatizing. Premedication with benzodiazepine is not effective in preventing recollection of anesthesia, however.

Clinical Trial Controlled Clinical TrialPredicting the depth of insertion of left-sided double-lumen endobronchial tubes.
To analyze the parameters that predict the depth of insertion of a left-sided double-lumen tube (DLT) and to assess the accuracy of the parameters after intubation. ⋯ The ideal depth of insertion of the left-sided DLT correlated significantly with patients' height and clavicular-to-carinal distance of the trachea. The best regression line enabled the left-sided DLT to be placed in an acceptable position without complications nearly 80% of the time.

Comparative Study Clinical Trial Controlled Clinical TrialThe use of a bronchial blocker compared with a double-lumen tube for single-lung ventilation during minimally invasive direct coronary artery bypass surgery.
To investigate whether a bronchial blocker (BB) placed through a routinely used single-lumen tube (SLT) to achieve 1-lung ventilation is appropriate in patients undergoing a minimally invasive direct coronary artery bypass (MIDCAB) operation. ⋯ To achieve 1-lung ventilation during a MIDCAB procedure, the use of a BB combined with an SLT is an appropriate technique as an alternative to the commonly used DLT.

Comparative Study Clinical TrialSevoflurane metabolite production in a small cohort of coronary artery bypass graft surgery patients.
To determine hepatic and renal effects of hexafluoroisopropanol in patients undergoing coronary artery bypass graft surgery under sevoflurane anesthesia. ⋯ The serum level of hexafluoroisopropanol after 0.5 MAC of sevoflurane anesthesia does not aggravate hepatic and renal functions.

Comparative StudyDoes intraoperative transesophageal echocardiography predict pulmonary valve dysfunction during the Ross procedure?
To determine the value of intraoperative transesophageal echocardiography for the assessment of the pulmonary valve anatomy and the pulmonary autograft performance in patients undergoing the Ross procedure. ⋯ Intraoperative transesophageal echocardiography allows assessment of autograft performance after implantation. This method is not helpful, however, in detecting pulmonary valve anatomic anomalies.
