Normobaric hyperoxia reduces cardiac index in patients after coronary artery bypass surgery.
The purpose of this study was to assess the hemodynamic changes in response to normobaric hyperoxia in patients immediately after coronary artery bypass surgery. ⋯ Exposing patients after coronary artery surgery to hyperoxia induces significant hemodynamic changes.

Comparative StudyOff-pump coronary artery bypass grafting reduces postoperative neurologic complications.
Complications occurring after coronary artery bypass graft (CABG) surgery, particularly neurologic damage, have been mainly correlated with the use of cardiopulmonary bypass (CPB). The aim of this work was to compare postoperative outcomes of patients undergoing CABG surgery, with or without the use of CPB, focusing on neurologic events. ⋯ In the authors' experience, off-pump CABG surgery offers some benefits compared with CPB in respect to major neurologic complications.

Feasibility and potential clinical utility of goal-directed transthoracic echocardiography performed by noncardiologist intensivists using a small hand-carried device (SonoHeart) in critically ill patients.
This study was designed to assess the clinical applicability of a small, handheld, portable transthoracic echocardiography device by noncardiologist intensivists. ⋯ After a brief formal training in using this handheld echocardiographic system in intensive care unit patients, surgical intensivists successfully performed and correctly interpreted a limited TTE in critically ill patients. Limited TTE provided new information and altered management in a significant number of patients. This study supports incorporating bedside goal-directed, limited TTE into intensivists' training programs.

Clinical TrialAnalysis of the interatrial septum by transesophageal echocardiography in adult cardiac surgical patients: anatomic variants and correlation with patent foramen ovale.
The purpose of this study was to document the perioperative prevalence of anatomic variants of the interatrial septum (IAS), to classify atrial septal aneurysm based on mobility pattern, and to correlate anatomic variants of IAS with patent foramen ovale (PFO). ⋯ IAS anatomic variants are common in adult cardiac surgical patients undergoing multiplane TEE. The presence of ASF and ASA predicts enhanced PFO detection. ASA mobility patterns significantly correlate ( p < 0.05) with the presence of PFO.
