Dynamic Needle Tip Positioning for Ultrasound-Guided Placement of a Peripherally Inserted Central Catheter in Pediatric Patients.
Although a few studies have reported the efficacy of ultrasound-guided peripherally inserted central catheter placement for pediatric patients, the procedure still is challenging. Ultrasound-guided dynamic needle tip positioning technique is useful for vascular catheterization. There have been no reports on using dynamic needle tip positioning for peripherally inserted central catheter placement. The authors assessed the rate of successful peripherally inserted central catheter placement with dynamic needle tip positioning. ⋯ In pediatric patients, ultrasound-guided peripherally inserted central catheter placement using dynamic needle tip positioning attained a high success rate.

Randomized Controlled TrialHigh-Flow Therapy by Nasal Cannulae Versus High-Flow Face Mask in Severe Hypoxemia After Cardiac Surgery: A Single-Center Randomized Controlled Study-The HEART FLOW Study.
To determine whether high-flow oxygen therapy by nasal cannulae (HFNC) is more effective than a high-flow face mask (HFFM) in severe hypoxemia. ⋯ In patients with severe hypoxemia after cardiac surgery, PaO2/FIO2 at 1 and 24 hours were higher and the use of noninvasive ventilation was reduced in HFNC compared with HFFM.

ReviewCalcium Administration During Weaning From Cardiopulmonary Bypass: A Narrative Literature Review.
The search for safe and effective patient management strategies during weaning from cardiopulmonary bypass is ongoing; intravenous calcium is occasionally used as a first-line drug. The physiologic role of calcium suggests that it can support the function of the cardiovascular system during this critical period. ⋯ Nonetheless, effects on clinically relevant endpoints are unknown, and possible systemic side effects, such as transient reduction in internal mammary artery graft flow, attenuation of the effects of β-sympathomimetics, "stone heart" phenomenon, and pancreatic cellular injury, may limit the use of calcium salts. Further studies are needed to expand the understanding of the effects of calcium administration on patient outcomes.

The authors hypothesized that automated tracings of both pulsed wave (PW) and continuous wave (CW) Doppler correlate well with manual measurements performed by an experienced echocardiographer. ⋯ Automated measurements of peak velocities, mean gradients, and VTI of spectral Doppler correlate closely with manual measurements performed by an experienced echocardiographer.

Historical ArticleMichael K. Cahalan: In Celebration of His Life and Contributions to Cardiac Anesthesiology.
Dr. Michael K. Cahalan, former chair of the Department of Anesthesiology at the University of Utah School of Medicine, died March 9, 2019, at the age of 69 after a brief illness. ⋯ He made many other important contributions to the specialty of anesthesiology, having achieved a notable measure of success in all the traditional missions of academics, including research, teaching, clinical care, and administration. In this summary, his early life, education, and the contributions he made to the practice of anesthesiology in general and to cardiac anesthesia and echocardiography in particular are reviewed. The attributes that made Cahalan a model in the profession of anesthesiology that all can strive to emulate also are described.
