Randomized Controlled TrialEffects of ventilatory mode during one-lung ventilation on intraoperative and postoperative arterial oxygenation in thoracic surgery.
The purpose of this study was to investigate the relationship between the ventilatory mode used during one-lung ventilation (OLV) and intraoperative and early postoperative arterial oxygenation in patients undergoing thoracic surgery. ⋯ In patients undergoing thoracic surgery, the use of PCV compared with VCV during OLV with the same Vt of 8 mL/kg does not affect arterial oxygenation during OLV or early postoperative oxygenation.

Randomized Controlled TrialThe association between the initial end-tidal carbon dioxide difference and the lowest arterial oxygen tension value obtained during one-lung anesthesia with propofol or sevoflurane.
The purpose of this study was to examine the correlation between the lowest PaO(2) value recorded during the first 45 minutes of one-lung ventilation (OLV) and the end-tidal CO(2) (ETCO(2)) difference between two-lung ventilation (TLV) and the early phase of OLV. ⋯ The present study indicates that the ETCO(2) difference between TLV and early OLV has an association with impaired oxygenation later during OLV. This would be a simple and clinically convenient predictor of the lowest PaO(2) value likely to be reached during one-lung anesthesia with either propofol or sevoflurane.

Comparative StudyComparison of a new cardiac output ultrasound dilution method with thermodilution technique in adult patients under general anesthesia.
The purpose of this study was to investigate the reliability of cardiac output (CO) measured by a new ultrasound dilution method (COud) in comparison with CO by pulmonary artery thermodilution (COtd) in adult patients undergoing surgery. ⋯ COud measurements agreed well with COtd. The results of this study indicated that COud might be interchangeable with conventional COtd in perioperative adult patients.

Comparative StudyAssessment of internal thoracic artery patency with transesophageal echocardiography during coronary artery bypass graft surgery.
The purpose of this study was to evaluate intraoperative transesophageal echocardiography (TEE) for assessing patency of internal thoracic artery grafts. ⋯ The authors concluded that the intraoperative assessment of LITA patency with TEE was a markedly useful and powerful tool for anesthesiologists during CABG surgery.

Airway interventions in the cardiac electrophysiology laboratory: a retrospective review.
To quantify the incidence of airway interventions during cardiac electrophysiology laboratory procedures. ⋯ These results suggest that a significant proportion of the authors' patients undergoing cardiac electrophysiology laboratory procedures required deep sedation if not general anesthesia, although a non-general anesthetic was planned. The issue of depth of sedation has implications for patient safety, privileging, and regulatory compliance. Based on the present results, the authors believe sedation for these procedures is best given by anesthesia providers; furthermore, caregivers should be aware that these procedures are likely to require deep sedation if not general anesthesia.
