Active cutaneous warming systems to prevent intraoperative hypothermia: a systematic review

Abstract

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.

Hipotermia no pós-operatório imediato: percepção de técnicos de enfermagem

“…A hipotermia é um evento comum no perioperatório 6 . É definida como a redução da temperatura corporal central abaixo de 36°C.…”

Clinical indicators of nursing outcomes classification for patient with risk for perioperative positioning injury: A cohort study

“…Furthermore, (0800) Thermoregulation, in Metabolic Regulation Class (Domain II Physiological Health), contains "outcomes describing the individual ability to regulate body metabolism" (Moorhead et al, 2012, p. 133). Hypothermia is a frequent event in the perioperative period associated with the effects of anesthesia, decreased metabolism, and exposure of the patient to the cold environment in the operating room (Poveda, Martinez, & Galvão, 2012). The assessment of (0800) Thermoregulation along with other outcomes allows the nursing team to choose the interventions that may mitigate this event.…”

“…The assessment of (0800) Thermoregulation along with other outcomes allows the nursing team to choose the interventions that may mitigate this event. Hence, the continuous assessment of the outcomes becomes relevant, since hypothermia often persists in the postoperative phase (Poveda et al, 2012). Hypothermia is also linked to cardiac complications such as arrhythmia and decreased blood volume, which may lead to peripheral vasoconstriction and, consequently, PU.…”

“…Hypothermia is also linked to cardiac complications such as arrhythmia and decreased blood volume, which may lead to peripheral vasoconstriction and, consequently, PU. (Fred, Ford, Wagner, & Vanbrackle, 2012;Poveda et al, 2012). Hence, NOC outcome (0800) Thermoregulation not only contributes to the assessment of preventive interventions, but also evaluates the development of PU due to surgical positioning through indicator (080007) Skin color changes.…”

Hypothermia Prevention During Surgery: Comparison Between Thermal Mattress And Thermal Blanket

“…Although there is evidence for the use of active heating methods for efficacy study with the objective of identifying the measures adopted in the operating room to prevent hypothermia during the intraoperative period, it pointed to the predominance of passive heating methods, perhaps due to the lack of more effective methods or difficulty acquiring devices because of the cost (9) .…”
