Background: Pandemics create challenges for medical centers, which call for innovative adaptations to care for patients during the unusually high census, to distribute stress and work hours among providers, to reduce the likelihood of transmission to health care workers, and to maximize resource utilization. Methods: We describe a multidisciplinary vascular access team’s development to improve frontline providers’ workflow by placing central venous and arterial catheters. Herein we describe the development, organization, and processes resulting in the rapid formation and deployment of this team, reporting on notable clinical issues encountered, which might serve as a basis for future quality improvement and investigation. We describe a retrospective, single-center descriptive study in a large, quaternary academic medical center in a major city. The COVID-19 vascular access team included physicians with specialized experience in placing invasive catheters and whose usual clinical schedule had been lessened through deferment of elective cases. The target population included patients with confirmed or suspected COVID-19 in the medical ICU (MICU) needing invasive catheter placement. The line team placed all invasive catheters on patients in the MICU with suspected or confirmed COVID-19. Results and conclusions: Primary data collected were the number and type of catheters placed, time of team member exposure to potentially infected patients, and any complications over the first three weeks. Secondary outcomes pertained to workflow enhancement and quality improvement. 145 invasive catheters were placed on 67 patients. Of these 67 patients, 90% received arterial catheters, 64% central venous catheters, and 25% hemodialysis catheters. None of the central venous catheterizations or hemodialysis catheters were associated with early complications. Arterial line malfunction due to thrombosis was the most frequent complication. Division of labor through specialized expert procedural teams is feasible during a pandemic and offloads frontline providers while potentially conferring safety benefits.

Long Term Stability

Nanobubbles have many potential applications depending on their types. The long-term stability of different gas nanobubbles is necessary to be studied considering their applications. In the present study, five kinds of nanobubbles (N2, O2, Ar + 8%H2, air and CO2) in deionized water and a salt aqueous solution were prepared by the hydrodynamic cavitation method. The mean size and zeta potential of the nanobubbles were measured by a light scattering system, while the pH and Eh of the nanobubble suspensions were measured as a function of time. The nanobubble stability was predicted and discussed by the total potential energies between two bubbles by the extended Derjaguin–Landau–Verwey–Overbeek (DLVO) theory. The nanobubbles, except CO2, in deionized water showed a long-term stability for 60 days, while they were not stable in the 1 mM (milli mol/L) salt aqueous solution. During the 60 days, the bubble size gradually increased and decreased in deionized water. This size change was discussed by the Ostwald ripening effect coupled with the bubble interaction evaluated by the extended DLVO theory. On the other hand, CO2 nanobubbles in deionized water were not stable and disappeared after 5 days, while the CO2 nanobubbles in 1 mM of NaCl and CaCl2 aqueous solution became stable for 2 weeks. The floating and disappearing phenomena of nanobubbles were estimated and discussed by calculating the relationship between the terminal velocity of the floating bubble and bubble size.
