“…In patients undergoing laparotomies [56], underbody resistive heating is associated with significantly lower final operative temperatures when compared with forced-air warming. This is surprising, as the posterior surface area available for resistive heating is greater than the limited upper body area during open abdominal surgery.…”

“…Furthermore, when evaluated against forced-air warming, an early non-clinical investigation with healthy volunteers showed that the heat transfer achieved from resistive heating was significantly greater [92]. However, the superiority of resistive heating over forced-air warming in this non-clinical study has not been reproduced in clinical trials, with the majority showing equivalence [54,55,[93][94][95][96] between devices and three favouring forced-air warming (Tables 3 and 4) [56,57,97].…”

“…It is important to note that many studies that show a benefit in the use of forced-air warming devices to reduce the risk of peri-operative hypothermia also use warmed intravenous fluids [46,48,50,[53][54][55][56][57][58]. Warmed fluids do not actively warm patients, but infusions below body temperature can be regarded as a form of active cooling.…”

Peri‐operative warming devices: performance and clinical application

SummarySince the adverse consequences of accidental peri-operative hypothermia have been recognised, there has been a rapid expansion in the development of new warming equipment designed to prevent it. This is a review of peri-operative warming devices and a critique of the evidence assessing their performance. Forced-air warming is a common and extensively tested warming modality that outperforms passive insulation and water mattresses, and is at least as effective as resistive heating. More recently developed devices include circulating water garments, which have shown promising results due to their ability to cover large surface areas, and negative pressure devices aimed at improving subcutaneous perfusion for warming. We also discuss the challenge of fluid warming, looking particularly at how devices' performance varies according to flow rate. Our ultimate aim is to provide a guide through the bewildering array of devices on the market so that clinicians can make informed and accurate choices for their particular hospital environment.

“…Forced air has been found favourable to other active warming strategies as well. Leung et al 27 compared forced-air warming with electric blanket warming during laparotomy. Mean temperatures at the end of surgery were 36.2 (0.4)°C and 35.2 (1.0)°C, respectively (P \ 0.01).…”

Purpose To highlight the role of anesthesiologists in the prophylaxis of surgical site infections (SSIs) and to recognize the central role they play in quality improvement initiatives for the prevention of SSIs. Source The medical literature was searched with a focus on three interventions affecting the risk of SSIs: preoperative antibiotic administration, perioperative normothermia, and perioperative hyperoxia. The literature was also searched for examples of initiatives in patient safety and quality improvement that highlight the role of anesthesiologists in preventing SSIs. Principal findings The timely administration of preoperative antibiotics and the maintenance of perioperative normothermia have been shown to reduce the risk of SSI significantly. Perioperative hyperoxia in the prevention of SSIs remains controversial but may improve outcomes in specific subsets of the surgical population. Initiatives in quality improvement show the challenges faced by many centres to improve upon these processes of care, but they also highlight the role of anesthesiologists as champions in the multidisciplinary efforts for the prevention of SSIs. Conclusions Anesthesiologists are responsible for many of the processes of care shown to impact the risk for SSIs, and they play an important role in the prevention of SSIs.

This study analyzed the evidence available in the literature concerning the effectiveness of different active cutaneous warming systems to prevent intraoperative hypothermia. This is a systematic review with primary studies found in the following databases: CINAHL, EMBASE, Cochrane Register of Controlled Trials and Medline. The sample comprised 23 randomized controlled trials. There is evidence in the literature indicating that the circulating water garment system is the most effective in maintaining patient body temperature. These results can support nurses in the decision-making process concerning the implementation of effective measures to maintain normothermia, though the decision of health services concerning which system to choose should also take into account its cost-benefit status given the cost related to the acquisition of such systems. Métodos activos de calentamiento cutáneo para la prevención de hipotermia en el período intraoperatorio: revisión sistemáticaLa finalidad del estudio fue analizar las evidencias disponibles en la literatura acerca de la efectividad de los diferentes métodos activos de calentamiento cutáneo para la prevención de hipotermia en el período intraoperatorio. Para esto, la revisión sistemática fue usada como método de revisión. La búsqueda de los estudios primarios fue efectuada en las bases de datos CINAHL, EMBASE, Cochrane Register of Controlled Trials y Medline.La muestra de la revisión abarcó 23 ensayos clínicos aleatorios controlados. La literatura ofrece evidencias que indican que el sistema de circulación de agua calentada es el método más efectivo en la manutención de la temperatura corporal. Los resultados evidenciados pueden subsidiar la toma de decisión del enfermero en la implementación de medidas efectivas para la manutención de la temperatura corporal. Sin embargo, considerando los costos de adquisición de los sistemas investigados, la elección del sistema en cada servicio de salud debería ser basada en el análisis de costo-beneficio.
