Randomized Controlled Trial Comparative Study
Ultrasound-guided saphenous nerve block - within versus distal to the adductor canal: a proof-of-principle randomized trial.
Reliable saphenous nerve blockade is a desirable complement to popliteal sciatic nerve blockade for foot and ankle surgery. We compared two promising ultrasound-guided techniques, the supine adductor canal (AC) technique and the prone peri-saphenous branch of the descending genicular artery (Peri-SBDGA) technique, using 8 mL of 2% lidocaine with epinephrine 1:400,000. ⋯ In this randomized trial, we found no differences in nerve visibility, block success rate, or onset between the AC and Peri-SBDGA techniques of ultrasound-guided saphenous nerve blockade, although the former technique provided superior vascular landmark visibility. Neither technique produced a sufficiently high success rate to provide reliable surgical anesthesia per se.

Comparative Study
Postoperative delirium following transcatheter aortic valve implantation: a historical cohort study.
Transcatheter aortic valve implantation (TAVI) techniques show favourable survival outcomes in high-risk patients, but the incidence of postoperative delirium is unknown. We conducted a historical cohort study to compare postoperative delirium in retrograde transfemoral (TF) versus anterograde transapical (TA) TAVI procedures. We also sought to identify independent predictors of delirium following TAVI. ⋯ Patients undergoing TA-TAVI had a markedly increased incidence of postoperative delirium compared with patients undergoing TF-TAVI.

Timely communication of intraoperative transesophageal echocardiography (TEE) findings to the postoperative care team is critical to optimizing patient care. We compared the use of a personal computer (PC) system with the use of a mobile tablet device (MTD) system for point-of-care TEE data entry and hypothesized that the MTD-based system would reduce the time to preliminary TEE reporting and decrease the incidence of delinquent reporting by 50%. ⋯ Implementation of a MTD system for data entry leads to improved TEE reporting time and reduces TEE reporting delinquency. Further studies are required to determine whether this strategy enhances quality of reporting, optimizes communication between care teams, and improves outcomes without increasing costs.

Partnerships for postgraduate medical education between institutions in high-income countries and low- and middle-income countries are increasingly common models that can create capacity in human resources for health. Nevertheless, data are currently limited to guide the development of this kind of educational program. ⋯ As a new and evolving program, the findings from this study highlight challenges and opportunities for faculty as part of a partnership for postgraduate medical education. Since maintaining an effective faculty is essential to ensure the sustainability of any teaching program, this work may help other similar programs to anticipate and overcome potential challenges.
