El cuidado de la salud del Ejército de los Andes del general San Martín / The health care of the Army of Andes of General San Martín

A través de la revisión de documentos históricos y otras fuentes bibliográficas, y desde la perspectiva de la enfermería, se describen los recursos y prácticas sanitarias con que contaba el equipo de salud que acompañó al cuerpo del Ejército de los Andes al mando del general José de San Martín desde el inicio del cruce de los Andes el 19 de enero en las Provincias Unidas del Río de la Plata, hasta finalizada la batalla de Chacabuco, en la Capitanía General de Chile, el 12 de febrero de 1817. Este trabajo nos permite conocer el trabajo de los primeros sanitarios militares que asistieron en el cuidado de los soldados de los ejércitos patrios y contribuir así a difundir la historia de la Medicina Argentina.

Through the review of historical documents and other bibliographic sources, and from the perspective of nursing, we describe the health resources and practices held by the health team that accompanied the Army of Los Andes under the command of General José de San Martín, from the start of crossing Los Andes on January 19th in the Provincias Unidas del Río de la Plata, to finish in the battle of Chacabuco, in the General Captaincy of Chile on February 12th, 1817. This work allows us to know the work of the first military health professionals who assisted in the care of the soldiers of the patriotic armies and contribute to spread the history of the Argentine Medicine.

Surgical clothing systems in laminar airflow operating room: a numerical assessment

This study compared two different laminar airflow distribution strategies - horizontal and vertical - and investigated the effectiveness of both ventilation systems in terms of reducing the sedimentation and distribution of bacteria-carrying particles. Three different staff clothing systems, which resulted in source strengths of 1.5, 4 and 5 CFU/s per person, were considered. The exploration was conducted numerically using a computational fluid dynamics technique. Active and passive air sampling methods were simulated in addition to recovery tests, and the results were compared. Model validation was performed through comparisons with measurement data from the published literature. The recovery test yielded a value of 8.1 min for the horizontal ventilation scenario and 11.9 min for the vertical ventilation system. Fewer particles were captured by the slit sampler and in sedimentation areas with the horizontal ventilation system. The simulated results revealed that under identical conditions in the examined operating room, the horizontal laminar ventilation system performed better than the vertical option. The internal constellation of lamps, the surgical team and objects could have a serious effect on the movement of infectious particles and therefore on postoperative surgical site infections
