Randomized Controlled TrialThe effect of thoracic epidural anesthesia on pulmonary shunt fraction and arterial oxygenation during one-lung ventilation.
To compare the effect of thoracic epidural local anesthetic, epidural opioid, and intravenous opioid on pulmonary shunt fraction, arterial oxygenation, and hemodynamic changes during one-lung ventilation (OLV) in patients undergoing thoracic surgery. ⋯ Thoracic epidural bupivacaine, epidural sufentanil, and intravenous remifentanil-combined general intravenous anesthesia have comparable effects on shunt fraction and arterial oxygenation during OLV in patients undergoing thoracic surgery.

Weaning mechanical ventilation after off-pump coronary artery bypass graft procedures directed by noninvasive gas measurements.
Partial pressure of carbon dioxide and oxygen were transcutaneously measured in adults after off-pump coronary artery bypass (OPCAB) surgery. The clinical use of such measurements and interchangeability with arterial blood gas measurements for weaning patients from postoperative mechanical ventilation were assessed. ⋯ More than three fourths of the patients were weaned from mechanical ventilation and extubated based on transcutaneous gas values alone after OPCAB surgery. The noninvasive transcutaneous carbon dioxide measurement can be used as a surrogate for arterial carbon dioxide measurement to manage postoperative OPCAB patients.

Comparative StudyA comparison of central and mixed venous oxygen saturation in circulatory failure.
The purpose of this study was to evaluate whether central venous oxygen saturation can be used as an alternative to mixed venous oxygen saturation in patients with cardiogenic and septic shock. ⋯ Central and mixed venous oxygen saturation measurements are not interchangeable numerically.

Risk factors for red blood cell transfusion after coronary artery bypass graft surgery.
Perioperative transfusion of red blood cells is associated with increased morbidity and mortality. The authors investigated the correlation between preoperative risk factors and the number of red blood cell units received in patients undergoing coronary artery bypass graft surgery. ⋯ In this study, the authors identified risk factors for receiving red blood cells in patients undergoing coronary artery bypass graft surgery. The authors were able to implement these factors in their daily practice by sharpening the criteria for the direct availability of red blood cells in the operating room.
