Randomized Controlled TrialIsoflurane, 0.5 minimum alveolar concentration administered through the precardiopulmonary bypass period, reduces postoperative dobutamine requirements of cardiac surgery patients: a randomized study.
Cardioprotective properties have been shown with halogenated volatile agents. It was hypothesized that low-dose isoflurane administered before aortic cross-clamping may reduce the amount of dobutamine required to improve impaired postoperative cardiac function after various types of cardiac surgery. ⋯ This study revealed that exposure to 0.5 MAC isoflurane before CPB reduced the total amount of dobutamine required to normalize postoperative cardiac dysfunction in various types of cardiac surgical patients.

Randomized Controlled Trial Comparative StudyCorrect depth of insertion of right internal jugular central venous catheters based on external landmarks: avoiding the right atrium.
Radiographically, a central venous catheter (CVC) tip should lie at the level of the right tracheobronchial angle. Precalculation of length of CVC insertion may avoid unnecessary catheter malposition. The purpose of this study was to assess the accuracy of a method of CVC positioning, based on external topographic landmarks. ⋯ It is recommended to use the topographic approach in deciding CVC depth with right internal jugular CVC placement.
