“…The operative room air conditioning system caused an ambient temperature fluctuation of 23.6°C ± 0.9°C, leading to variation in the fluid temperature before warming. However, the recommended operating room temperature that can prevent perioperative hypothermia ranges from 20°C to 24°C, which was within our range [ 12 , 13 ]. The initial temperature of the fluid before warming is 24.9°C ± 0.5°C, higher than the room temperature may be from the different location of measurement and not well distributed of airflow.…”

Introduction In patients who require a massive intraoperative transfusion, cold fluid or blood transfusion can cause hypothermia and potential adverse effects. One method by which to prevent hypothermia in these patients is to warm the intravenous fluid before infusion. The aim of this study was to determine the effect of the fluid flow rate on the efficacy of a fluid warmer. Methods The room air temperature was controlled at 24°C. Normal saline at room temperature was used for the experiment. The fluid was connected to an infusion pump and covered with a heater line, which constantly maintained the temperature at 42°C. The fluid temperature after warming was measured by an insulated thermistor at different fluid flow rates (100, 300, 600, 900, and 1200 mL/h) and compared with the fluid temperature before warming. Effective warming was defined as an outlet fluid temperature of >32°C. Results The room temperature was 23.6°C ± 0.9°C. The fluid temperature before warming was 24.95°C ± 0.5°C. The outlet temperature was significantly higher after warming at all flow rates (p < 0.001). The increases in temperature were 10.9°C ± 0.1°C, 11.5°C ± 0.1°C, 10.2°C ± 0.1°C, 10.1°C ± 0.7°C, and 8.4°C ± 0.2°C at flow rates of 100, 300, 600, 900, and 1200 mL/h, respectively. The changes in temperature among all different flow rates were statistically significant (p < 0.001). The outlet temperature was >32°C at all flow rates. Conclusions The efficacy of fluid warming was inversely associated with the increase in flow rate. The outlet temperature was <42°C at fluid flow rates of 100 to 1200 mL/h. However, all outlet temperatures reached >32°C, indicating effective maintenance of the core body temperature by infusion of warm fluid.

“…Sobre os dispositivos conhecidos para aquecer o paciente, a equipe mostra conhecer alguns que não estão comumente disponíveis no serviço, como colchões, mantas térmicas e botas. Entre as principais medidas a serem tomadas para manutenção da normotermia dos pacientes destacam-se: os métodos passivos com aquecimento por meio de exposição limitada da pele e uso de cobertores de algodão, e os métodos mais eficazes de aquecimento ativo por meio do uso de colchões térmicos, infusão de líquidos aquecidos, aquecimento e umidificação dos gases administrados (9,10,15,16) . Além dessas medidas, recomenda-se o aumento da temperatura da sala cirúrgica quando o aquecimento ativo não é viável ou não é suficiente para aquecer o paciente (17) .…”

Objetivo: Avaliar o conhecimento e intervenções da equipe de enfermagem sobre hipotermia perioperatória no paciente cirúrgico. Método: Estudo descritivo-exploratório com corte transversal de abordagem quantitativa. Foi realizada a coleta dos dados com 77 profissionais entre enfermeiros e técnicos de enfermagem atuantes no bloco operatório e da sala de recuperação pós-anestésica de um hospital de referência em cirurgias de alta complexidade. Resultados :A pesquisa evidencia que os participantes obtêm conhecimento básico sobre o assunto, principalmente sobre o conceito, os sinais, os sintomas e como intervir quando o paciente apresenta o problema. As complicações e o seu manejo apresentam-se como uma dificuldade. Conclusão: O conhecimento sobre hipotermia perioperatória e as intervenções da equipe enfermagem apresenta lacunas. Espera-se contribuir no planejamento de ações educativas que norteiem as estratégias de assistência de qualidade ao paciente cirúrgico.

Indoor air quality (IAQ) is important, especially in settings with a high number of users, such as healthcare facilities, where the vulnerable patients count is more. Both developed and developing nations are currently paying attention to the issue of indoor air quality (IAQ). IAQ values are influenced by several parameters, with temperature and humidity being the most significant contributors. Very few studies have examined the impact of hospital temperature and humidity on indoor air quality, because they are directly related to thermal comfort. As defined by indoor environmental quality (IEQ), these parameters were selected. This article provides an overview of the significance of temperature and humidity in hospital environments, the criteria provided by the authors based on guidelines and standards, and the relationship between the two along with a few other parameters. In addition, the article attempted to determine the nosocomial infections caused by indoor air temperature and humidity. The study assumes that even though the parameters have been specified in various standards, they can vary according to space usage, occupancy, HVAC design, climate zones, etc. This research may result in a paradigm shift regarding the significance of temperature and humidity in hospitals.
