Observational StudyThe Optimal Angle of Head Rotation for Internal Jugular Cannulation as Determined by Ultrasound Evaluation.
The aim of this study was to determine the degree of head rotation that creates the maximal anatomic separation between the right internal jugular vein and the carotid artery. ⋯ The authors found the internal jugular vein becomes more vertically separated from the carotid artery at more extreme angles of contralateral head rotation.

Hemodilution Combined With Hypercapnia Impairs Cerebral Autoregulation During Normothermic Cardiopulmonary Bypass.
To investigate the influence of hemodilution and arterial pCO2 on cerebral autoregulation and cerebral vascular CO2 reactivity. ⋯ Hemodilution down to a hematocrit of<28% combined with hypercapnia negatively affects dynamic cerebral autoregulation, which underlines the importance of tight control of both hematocrit and paCO2 during CPB.

Preoperative Echocardiographic Parameters of Diastolic Dysfunction did not Provide a Predictive Value for Postoperative Atrial Fibrillation in Lung and Esophageal Cancer Surgery.
To evaluate the predictive value of preoperative transthoracic echocardiography in the development of postoperative atrial fibrillation after non-cardiac thoracic surgery. ⋯ These results were similar to those published elsewhere on POAF incidence and risk factors. The preoperative echocardiographic variables in this study did not provide predictive value for POAF in non-cardiac thoracic surgery.
