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.

Randomized Controlled TrialVolume replacement with a balanced hydroxyethyl starch (HES) preparation in cardiac surgery patients.
Balanced fluids appear to be have advantages over unbalanced fluids for correcting hypovolemia. The effects of a new balanced hydroxyethyl starch (HES) were studied in cardiac surgery patients. ⋯ A plasma-adapted HES preparation in addition to a balanced crystalloid resulted in significantly less decline in BE, less increase in concentrations of kidney-specific proteins, less inflammatory response and endothelial damage, and fewer changes in hemostasis compared with an unbalanced fluid strategy.
