Observational StudyThe Effects of Positioning on the Volume/Location of the Internal Jugular Vein Using 2-Dimensional Tracked Ultrasound.
To investigate the effects of different positioning on the volume/location of the internal jugular vein (IJV) using 2-dimensional (2D) tracked ultrasound. ⋯ Trendelenburg position significantly increased the CSA of the IJV, thus facilitating IJV cannulation. This new 3D reconstruction method permits the creation of a 3D volume through a tracked 2D ultrasound scanning system with image acquisition and integration and may prove useful in providing the user with a "road map" of the vascular anatomy of a patient's neck or other anatomic structures.

Observational StudyCharacteristics associated with Publication of Randomized Controlled Trials in the Journal of Cardiothoracic and Vascular Anesthesia: A 15-Year Analysis, 2004-2018.
Randomized controlled trials (RCTs) provide important data to guide clinical decisions. Publication bias may limit the applicability of RCTs because many clinical investigators prefer to submit and journals more selectively accept studies with positive results. The authors tested the hypothesis that positive RCTs published in the Journal of Cardiothoracic and Vascular Anesthesia were more likely to be associated with factors known to predict publication of positive versus negative RCTs in other journals. ⋯ The percentage of RCTs that identified a randomization method, were registered, or followed CONSORT guidelines increased in a time-dependent manner. No differences in any factors associated with publication of RCTs were observed when positive and negative trials were compared. The Journal of Cardiothoracic and Vascular Anesthesia publishes more positive than negative RCTs, but factors that have been previously associated with RCT publication in other journals were similar between groups.

Observational StudyDynamic Tests to Predict Fluid Responsiveness After Off-Pump Coronary Artery Bypass Grafting.
To test the hypothesis that a positive end-expiratory pressure test and the mini-fluid challenge predict fluid responsiveness in patients after off-pump coronary artery bypass grafting. ⋯ Both the positive end-expiratory pressure test and the mini-fluid challenge test are feasible after off-pump coronary artery bypass grafting and can be used to predict fluid responsiveness in these patients.

Observational StudyUse of Transesophageal Echocardiogram and Interdisciplinary Approach to Intraoperative Management of Renal Cell Carcinoma With Inferior Vena Cava Invasion.
Report experience of patients undergoing surgery for resection of renal cell carcinoma with inferior vena cava invasion and use of transesophageal echocardiogram (TEE). ⋯ The surgical management of renal cell carcinoma with inferior vena cava tumor extension is complex. High-grade tumors require individualized treatment. Successful outcomes require collaboration between surgeons and anesthesiologists. Patients with level IIIb to IV tumor invasion benefit from TEE assessment and monitoring, which may be life-saving, and cardiac anesthesia should be involved in those types of cases.

Fifty Percent Effective Dose of Intranasal Dexmedetomidine Sedation for Transthoracic Echocardiography in Children With Cyanotic and Acyanotic Congenital Heart Disease.
To determine the 50% and 95% effective dose of intranasal dexmedetomidine sedation for transthoracic echocardiography in children with cyanotic and acyanotic congenital heart disease. ⋯ The 50% (95% confidence intervals) effective doses of intranasal dexmedetomidine sedation for transthoracic echocardiography were 3.2 (2.78-3.55) μg/kg and 1.9 (1.69-2.06) μg/kg in children with cyanotic and acyanotic congenital heart disease, respectively.
