ABSTRACT

There are limited data on the use of extracorporeal membrane oxygenation (ECMO) for pregnant and peripartum women with COVID-19 associated acute respiratory distress syndrome (ARDS). Pregnant women may exhibit more severe infections with COVID-19, requiring intensive care. We supported nine pregnant or peripartum women with COVID-19 ARDS with ECMO, all surviving and suffering no major complications from ECMO. Our case series demonstrates high-maternal survival rates with ECMO support in the management of COVID-19 associated severe ARDS, highlighting that these pregnant and postpartum patients should be supported with ECMO during this pandemic.

ABSTRACT

INTRODUCTION: Several animal models have been utilized for in-vitro experimentation and surgical training exercises of the vas deferens. The canine model is currently the standard for both in-vivo and ex-vivo study. Due to increasing costs associated with experimentation on canines, and in keeping with the principles of refine, reduce, and replace, a novel model that is cost-effective and easily obtained is desired. We compared morphology of the bull vas deferens to that of the human and the canine. MATERIALS AND METHODS: Bilateral vas deferens tissue from the human (n = 6), canine (n = 6), and bull (n = 5) were compared. Outer diameter (OD), inner diameter (ID), and microscopic measurements of the luminal mucosa and muscularis were then determined from each of these tissues. Histological comparisons were performed by a single pathologist. Data was analyzed using Two One-sided Tests (TOST) Analysis of Equivalence. RESULTS: According to the TOST statistical analysis, the vassal ID was equivalent for all three species. Similarly, equivalent microscopic measurements were noted for both vassal mucosal (human-canine and human-bull) and muscularis thicknesses (canine-bull). Lastly, all three species had similar histological characteristics. CONCLUSIONS: The vas deferens' of the human, canine, and bull are equivalent in many ways, including histological similarities. It is reasonable to conclude that the bull vas could be substituted for the human vas for both in-vitro testing and microscopic vasovasostomy simulation exercises. Specimens are cost-effective, provide ample tissue length, and are easy to obtain.
