Clinical evaluation of reflectance spectrophotometry for the measurement of gastric microvascular oxygen saturation in patients undergoing cardiopulmonary bypass.
To evaluate the impact of cardiopulmonary bypass (CPB) on gastric mucosal oxygen saturation assessed by reflectance spectrophotometry in patients undergoing coronary artery bypass graft surgery. ⋯ Reflectance spectrophotometry allowed the authors to assess gastric mucosal oxygen saturation with a high repetition rate, regardless of spontaneous circulation with pulsatile flow or nonpulsatile flow during CPB. This technique provided the means to monitor on-line the course of tissue oxygen saturation throughout the operative procedure. Reflectance spectrophotometry is an appropriate and sensitive assessment tool to monitor gastric mucosal oxygen saturation in patients undergoing CPB.

Randomized Controlled Trial Comparative Study Clinical TrialComparison between repeat bolus intrathecal morphine and an epidurally delivered bupivacaine and fentanyl combination in the management of post-thoracotomy pain with or without cyclooxygenase inhibition.
To compare the analgesic efficacy of a traditional epidurally delivered bupivacaine/fentanyl combination with a repeat bolus intrathecal morphine technique in the management of post-thoracotomy pain and to assess further the effect of cyclooxygenase (COX) inhibition on both modalities. ⋯ The intrathecal morphine and nimesulide combination offered significantly better analgesia than any other combination studied. The efficacious interaction between opioids and nonsteroidal anti-inflammatory drugs may be COX-2 mediated.

Randomized Controlled Trial Comparative Study Clinical TrialDoes ultrasound imaging before puncture facilitate internal jugular vein cannulation? Prospective randomized comparison with landmark-guided puncture in ventilated patients.
To investigate whether prepuncture ultrasound evaluation of vascular anatomy facilitates internal jugular vein cannulation compared with landmark-guided puncture. ⋯ Prepuncture ultrasound evaluation did not improve the result of right internal jugular vein cannulation compared with the respiratory jugular venodilation-guided approach. When the landmark was not observed, however, the prepuncture ultrasound guidance was helpful in facilitating the cannulation.

Differences in arterial and venous thromboelastography parameters: potential roles of shear stress and oxygen content.
To investigate potential mechanisms for the differences in thromboelastography variables observed between arterial blood samples and venous blood samples. ⋯ These data show that differences exist in thromboelastography values between arterial and venous blood samples and, more importantly, show that the differences observed are not related to differences in oxygen content. These differences seem to be related to differences in catheter lumen diameter and, presumably, shear forces.

Transesophageal echocardiography for cardiac surgery in children.
To evaluate the usefulness of transesophageal echocardiography (TEE) for cardiac surgery in children. ⋯ TEE is a valuable diagnostic tool for monitoring during cardiac surgery in children. The person who performs the TEE should use it carefully after obtaining thorough knowledge of the pathophysiology of pediatric cardiac diseases, their surgical indications, and how specific surgical procedures are done.
