ABSTRACT
Coronavirus is human-to-human transmissible and often leads to nosocomial outbreak in the early stage, which poses a great threat to healthcare workers.Due to confined space, crowed population and some aerosol-generating medical procedures, hospital is vulnerable to coronavirus transmission and nosocomial infection.We review the mechanism and risk factors of coronavirus aerosol in hospital and summarize the evidence of aerosol transmission of three coronaviruses and the impact of air flow.Furthermore, we evaluate the effectiveness of personal protection in the above-mentioned scenarios for the prevention and control of nosocomial infection.
ABSTRACT
Las reacciones anafilácticas intraoperatorias son impredecibles, infrecuentes y pueden poner en riesgo al paciente. Tienen una incidencia de 1/10 000 a 1/20 000 produciéndose en la mayoría de los casos por bloqueantes musculares, látex y antibióticos. No hay estadística de las reacciones alérgicas sistémicas durante otros procedimientos médicos. El estudio diagnóstico posterior a una reacción es complejo debiendo incluir toda la medicación utilizada en el procedimiento. En este estudio retrospectivo describimos 15 pacientes, de los cuales 10 tuvieron reacciones anafilácticas en un procedimiento quirúrgico, 2 en endoscopías y 1 en una ecografía transvaginal. Los dos pacientes restantes presentaron una reacción alérgica sistémica durante una ecografía transvaginal y un procedimiento odontológico. Estudiamos los pacientes con toda la medicación utilizada, incluimos látex y, eventualmente, los detergentes y desinfectantes, de haber sido empleados. Tres de las 10 cirugías no pudieron realizarse por desarrollarse la reacción durante la inducción anestésica, en cinco casos debieron interrumpirse y solo en dos se terminaron. Las reacciones posteriores a endoscopías fueron severas, requiriendo internación en terapia intensiva; las reacciones en ecografías transvaginales y procedimientos odontológicos fueron asistidas en emergencias. Los agentes causales en las cirugías incluyeron bloqueantes musculares, látex, cefalosporina, azul patente y ranitidina; en endoscopías el agente causal fue el orto-ftalaldehído (OPA), en las ecografías transvaginales el látex y en el procedimiento odontológico la amoxicilina. El objetivo de este artículo es describir la etiología de las reacciones alérgicas sistémicas y anafilácticas intraoperatorias y en procedimientos médicos, recalcando su gravedad y la necesidad de su identificación.
Anaphylaxis during anesthesia is an unpredictable, severe, and rare reaction. It has an incidence of 1/10 000 to 1/20 000 surgeries. In most series, the responsible drugs include neuromuscular blocking agents, latex, or antibiotics. The frequency and etiology of systemic allergic reactions in other medical procedures are largely unknown. The identification of responsible drugs of anaphylaxis is a complex task, requiring testing of all medications and substances used during surgery. We describe our experience in a retrospective study of 15 patients. Ten subjects developed anaphylaxis during surgery, two in endoscopic studies and one in a trans-vaginal ultrasound. The remaining two subjects, one in a trans-vaginal ultrasound and another during a dental procedure had a systemic allergic reaction. We studied all patients with all medications administered during the procedures, including latex and detergents and disinfectants. Three surgeries had to be suspended at induction of anesthesia, five were stopped incomplete and two were completed. Both patients that presented a reaction during endoscopy required intensive care unit admission and the rest were observed in a Hospital. The responsible drugs during surgery anaphylaxis were neuromuscular blocking agents, latex, patent blue, and ranitidine. Ortho-phthalaldehyde (OPA) was identified during endoscopic studies; latex was responsible in transvaginal ultrasounds; and amoxicillin in the dental procedure. The aim of the present article is to review our experience studying allergic systemic reactions and anaphylaxis during general anesthesia and medical procedures, emphasizing the severity of these reactions and the need for causative drug identification.

It is the most important issue in elder society how medical expenditure will be managed. Government has decided the basic policy concerning Fee Schedule System Amendment in March of this year. The basic policy was made by three part, one is appropriate evaluation on medical procedure, second is appropriately reflected hospital cost and third is amendment by patient view. Subcommittee of Cyuikyo had decided to set organizations to survey and research on fee schedule system. Hereinafter, it will be more important to build new and scientifically system based on these data.
