Pre- and Post-Bypass Platelet Function Testing With Multiple Electrode Aggregometry and TEG Platelet Mapping in Cardiac Surgery.
To investigate the differences between pre- and post-cardiopulmonary bypass platelet function tests and to examine whether post-bypass tests could predict postoperative bleeding. ⋯ Post-bypass platelet function testing showed reductions in ADP and arachidonic acid-triggered aggregation but not in TRAP-triggered aggregation compared with pre-bypass testing. There was no relationship between the post-bypass tests and bleeding.

Observational StudyInadvertent Hypothermia After Procedural Sedation and Analgesia in a Cardiac Catheterization Laboratory: A Prospective Observational Study.
To identify the prevalence of and risk factors for inadvertent hypothermia after procedures performed with procedural sedation and analgesia in a cardiac catheterization laboratory. ⋯ A moderate prevalence of hypothermia was observed. The small absolute change in temperature observed may not be a clinically important amount. More research is needed to increase confidence in the authors' estimates of hypothermia in sedated patients and its impact on clinical outcomes.

Observational StudyPredicting New-Onset Postoperative Atrial Fibrillation in Cardiac Surgery Patients.
To derive a simple clinical prediction rule identifying patients at high risk of developing new-onset postoperative atrial fibrillation (POAF) after cardiac surgery. ⋯ This study proposed a simple predictive score incorporating three risk variables to identify cardiac surgical patients at high risk of developing new-onset POAF. Preventive treatment should target patients ≥ 65 years with left atrial dilatation and mitral valve disease.

Observational StudyNeurologic Derangement and Regional Cerebral Oxygen Desaturation Associated With Patency of the Circle of Willis During Carotid Endarterectomy.
To explore the relationship between the maximal fractional decrease of regional cerebral oxygen saturation (rSO2) in neurologic derangement and the patency of the circle of Willis and contralateral carotid artery stenosis. ⋯ The rSO2 can be used to predict shunt insertion, regardless of the patency of the circle of Willis. The probability of shunt insertion increased with increasing degree of contralateral carotid artery stenosis in the absence of anterior circulation in the circle of Willis.

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.
