Resumo Objetivo Analisar a associação entre variáveis sociodemográficas, clínicas, cirúrgicas e ambientais e ocorrência de hipotermia. Métodos Estudo transversal e analítico, realizado com 105 pacientes adultos de ambos os sexos. O coeficiente de Pearson verificou a correlação entre a temperatura dos pacientes com a duração do período anestésico-cirúrgico, a permanência na sala de operações e a média de temperatura na sala cirúrgica. Resultados Dos 105 (100%) participantes, 73 (69,5%) era do sexo feminino e 85 (81%) na idade adulta. A hipotermia ocorreu em 98 (93,3%) dos pacientes. No início do procedimento anestésico, a média de temperatura foi de 36,1°C, com diminuição gradativa atingindo 34°C de média. No início da indução anestésica, 29 (27,6%) pacientes apresentavam temperatura auricular <36°C e, 60 minutos após a indução, 78 (85,7%) pacientes encontravam-se hipotérmicos e com temperatura média de 35,2°C. Ao final do procedimento anestésico, 93 (88,6%) pacientes tiveram hipotermia com valor mínimo de 31,4ºC. Conclusão Não houve correlação significativa entre a média de temperatura do paciente e as médias de temperatura da sala cirúrgica. As variáveis sexo feminino, anestesia combinada, duração do procedimento e o tempo de permanência na sala cirúrgica foram estatisticamente significantes para predizer hipotermia.
Abstract Objective To analyze the association between sociodemographic, clinical, surgical and environmental variables and the occurrence of hypothermia. Methods Cross-sectional and analytical study conducted with 105 adult patients of both genders. The Pearson’s coefficient showed a correlation between the patients’ temperature with the duration of the anesthetic-surgical period, the stay in the operating room, and the average temperature in the operating room. Results Of the 105 (100%) participants, 73 (69.5%) were female and 85 (81%) were adults. Hypothermia occurred in 98 (93.3%) patients. The average temperature was 36.1°C at the start of anesthetic procedure, with gradual decrease, reaching the average of 34°C. At the beginning of anesthetic induction, 29 (27.6%) patients had ear temperature <36 ° C and 60 minutes after induction, 78 (85.7%) patients were hypothermic, with an average temperature of 35.2 ° C. At the end of anesthesia, 93 (88.6%) patients had hypothermia with a minimum temperature of 31.4ºC. Conclusion There was no significant correlation between the patient’s average temperature and the average temperature of the operating room. The variables of female gender, combined anesthesia, duration of the procedure and the length of stay in the operating room were statistically significant to predict hypothermia.
