Factors associated to the development of hypothermia in the intraoperative period

Abstract

Poveda VB, Galvão CM, Santos CB. Factors associated to the development of hypothermia in the intraoperative period. Rev Latino-am Enfermagem 2009 março-abril; 17(2):228-33.This study aimed to assess factors associated to body temperature changes intraoperatively in patients undergoing elective surgery. A prospective study including 70 patients was carried out in a charity hospital. A data collection instrument was developed and its face and content validity was established. The variables measured were operating room temperature and humidity and patient body temperature at different times. In the multivariate linear regression, the variables type of anesthesia, duration of anesthesia, body mass index, and operating room temperature were directly associated to mean body temperature. Nurses are responsible for planning and implementing effective interventions that can contribute to minimize costs and most importantly reduce hypothermia complications. DESCRIPTORS: hypothermia; perioperative nursing; research FACTORES RELACIONADOS AL DESARROLLO DE HIPOTERMIA EN EL PERÍODO INTRAOPERATORIO La investigación tuvo como objetivo analizar los factores relacionados a las alteraciones de la temperatura corporal del paciente sometido a cirugía electiva en el período intraoperatorio. Para esto, se realizó un estudio de correlación, prospectivo, en un hospital filantrópico. Fue elaborado un instrumento y sometido a validación aparente y de contenido, el cual fue utilizado para recolectar datos de 70 pacientes. La temperatura y humedad de la sala de operación y la temperatura corporal del paciente, en diferentes momentos, fueron las variables mensuradas. En la regresión linear multivariada, las variables: tipo de anestesia, duración de la anestesia, índice de masa corporal y temperatura de la sala de operación estaban directamente relacionadas a la temperatura corporal promedio de los sujetos investigados. Es el enfermero quien debe planificar e implementar intervenciones efectivas que contribuyan para minimizar los costos y principalmente reducir las complicaciones asociadas a la hipotermia. DESCRIPTORES: hipotermia; enfermería perioperatoria; investigación FATORES RELACIONADOS AO DESENVOLVIMENTO DE HIPOTERMIA NO PERÍODO INTRA-OPERATÓRIO A pesquisa teve como objetivo analisar os fatores relacionados às alterações da temperatura corporal do paciente submetido à cirurgia eletiva no período intra-operatório. Para tal, realizou-se estudo correlacional, prospectivo, em um hospital filantrópico. Foi elaborado um instrumento e submetido à validação aparente e de conteúdo, o qual foi utilizado para a coleta de dados de 70 pacientes. A temperatura e umidade da sala de operação, a temperatura corporal do paciente em diferentes momentos foram as variáveis mensuradas.

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

“…Preventing hypothermia in patients during the intraoperative period can prevent complications associated with such an event, reduce hospital costs, improve the patients' thermal comfort and, consequently, their satisfaction (39) . This systematic review supports the development of institutional policies intended to prevent this event.…”

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

“…The increased length of stay of patients in the PA-CU is associated with complications from intraoperative hypothermia, reflecting increased costs, need for transfusions, administration of medications and ordering additional laboratory tests (2) . Patients heated by active heating air systems remain shorter time in PACU, as well as minimizing costs associated with postoperative hypothermia (18) .…”

“…It occurs due to the abolition of behavioral responses after anesthetic induction, increased patient exposure to the environment (refrigerated rooms), central inhibition of thermoregulation induced by anesthetics, internal interior redistribution of heat, thoracic or abdominal cavity and infusion of cold solutions (2) . Among the implications related to the occurrence of unintended perioperative hypothermia include increased risk of bleeding, tachycardia, morbid cardiac events, surgical site infection and prolonged hospital stay (3) .…”
