Validation of the effectiveness of augmented reality-assisted vascular puncture: An experimental model.

PURPOSE: To demonstrate that the augmented reality-assisted puncture technique improves the efficacy of ultrasound-guided puncture to get central venous access (CVA), allows the image to be obtained without limitations, freeing the hands and keeping the gaze continuously on the working field, which contributes to improving the safety of the procedure. MATERIAL AND METHODS: A gelatin mould with a latex surface and a chicken breast with silicone tubes inside were used to simulate vascular punctures. Images were obtained by an ultrasound scanner and post-processed with a specific software. A hologram was obtained and projected onto the previously delimited surface to be punctured. The variables related to image acquisition, the characteristics of the structure to be cannulated and the percentage of successes in the first attempt were analysed. Six operators were involved, using different ultrasound scanners. Efficiency was examined after the application of technical improvements in the process. RESULTS: Seventy-six punctures were performed, guided by two different ultrasound scanners, divided into two groups: 37 with 33 successes (sigma = 3.52 with a process efficiency of 97.98%) and after technical improvements, 39 with 38 successes (sigma = 4.07 with a process efficiency of 99.4%). There are no significant differences among the operators (X2 p = 0.47) and between the ultrasound scanners (X2 p = 0.56). CONCLUSIONS: The augmented reality ultrasound-assisted CVA technique may be the next step in standardising the process of cannulation of vascular structures. This technique provides greater accuracy, greater comfort by freeing the hands and keeping the gaze on the working field, better ultrasound image quality, and eliminates variability between operators and sonographers.

Telemedicine in the face of the COVID-19 pandemic / Telemedicina frente a la pandemia de COVID-19

The novel coronavirus SARS-CoV-2 is a positive single-stranded RNA virus that can be immediately translated and integrated into the host cell with its own RNA messenger, facilitating replication inside the cell and infectivity. The rapid progression of the disease presents a real challenge for the whole world. As the usual capacity for citizen care is exceeded, health professionals and governments struggle. One of the most important strategies to reduce and mitigate the advance of the epidemic are social distance measures; this is where telemedicine can help, and provide support to the healthcare systems, especially in the areas of public health, prevention and clinical practices, just as it is doing in others sectors. Telemedicine connects the convenience, low cost, and ready accessibility of health-related information and communication using the Internet and associated technologies. Telemedicine during the coronavirus epidemic has been the doctors’ first line of defense to slow the spread of the coronavirus, keeping social distancing and providing services by phone or videoconferencing for mild to focus personal care and limited supplies to the most urgent cases

El nuevo coronavirus SARS-CoV-2 es un virus de ARN monocatenario positivo que puede traducirse inmediatamente e integrarse en la célula huésped con su propio mensajero de ARN, facilitando la replicación dentro de la célula y la infectividad. La rápida progresión de la enfermedad presenta un verdadero desafío en todas las partes del mundo. A medida que se excede la capacidad habitual de atención sanitaria a los ciudadanos pueden generarse tensiones entre los profesionales de la salud y los gobiernos. Una de las estrategias más importantes para reducir y mitigar el avance de la epidemia son las medidas de distanciamiento social. Aquí es donde la telemedicina puede ayudar y brindar apoyo a los sistemas de salud, especialmente en las áreas de salud, prevención y prácticas clínicas, tal como se está están haciendo en otros sectores. La telemedicina conecta la conveniencia, el bajo costo y la fácil accesibilidad de la información y la comunicación relacionadas con la salud a través de Internet y las tecnologías asociadas. La telemedicina durante la epidemia de coronavirus ha sido la primera línea de defensa de los sanitarios para para frenar la propagación del coronavirus, brindando servicios por teléfono o videoconferencia para atención personalizada en casos leves y limitando los recursos sanitarios para los casos más urgentes
