“…In the present study, the administration of a lower volume of intraoperative fluid was significantly associated with IOH. However, this finding was inconsistent with those of previous studies [ 36 , 37 ]. These variations could be due to differences in the technique of measurement and may be due to difference in sample population.…”

Aims To construct and validate an intraoperative hypothermia risk prediction model for elderly patients undergoing total hip arthroplasty (THA). Methods We collected data from 718 patients undergoing THA in a tertiary hospital from January 2021 to December 2022. Of these patients, 512 were assigned to the modeling group from January 2021 to April 2022, and 206 participants were assigned to the validation group from May 2022 to December 2022. A logistic regression analysis was performed to construct the model. The area under the curve (AUC) was used to test the model’s predictive ability. Results The incidence rate of intraoperative hypothermia was 51.67%. The risk factors entered into the risk prediction model were age, preoperative hemoglobin level, intraoperative blood loss, postoperative hemoglobin level, and postoperative systolic blood pressure. The model was constructed as follows: logit (P) = − 10.118 + 0.174 × age + 1.366 × 1 (preoperative hemoglobin level) + 0.555 × 1 (postoperative hemoglobin level) + 0.009 × 1 (intraoperative blood loss) + 0.066 × 1 (postoperative systolic blood pressure). Using the Hosmer–Lemeshow test, the P value was 0.676 (AUC, 0.867). The Youden index, sensitivity, and specificity were 0.602, 0.790, and 0.812, respectively. The incidence rates of intraoperative hypothermia in the modeling and validation groups were 53.15% and 48.06%, respectively. The correct practical application rate was 89.81%. This model had good application potential. Conclusions This risk prediction model has good predictive value and can accurately predict the occurrence of intraoperative hypothermia in patients who undergo THA, which provides reliable guidance for clinical work and has good clinical application value.

“…The study showed that neonates and infants had an AOR of 6 (with a 95% CI of 3.7 to 9.8) and 4.5 (with a 95% CI of 2.9 to 7), respectively. These findings are consistent with a previous study conducted in 2022 at Addis Ababa public hospitals by Getachew Mekete, which also found a significant association between intraoperative hypothermia and pediatric patients, including neonates and infants 17 , 21 . The possible reason for this association is that pediatrics have a higher surface area to volume ratio, immature hypothalamic thermoregulatory capacity, and less insulating subcutaneous tissue, which makes them more susceptible to heat loss.…”

“…During our study, we found that children who had undergone surgery for more than 120 min and received anesthesia for more than 120 min were significantly more likely to experience intraoperative hypothermia. This finding aligns with the results of a previous study conducted in 2010 at the Michigan Hospital and Health Center in the United States of America, as well as a study done at Tikur Anbessa Specialized Hospital in Addis Ababa, Ethiopia 4 , 17 . One possible explanation for this association is that patients who undergo prolonged surgery and anesthesia may experience a decrease in their response to heat loss due to the suppression of the thermoregulatory center by the anesthetic agent.…”

“…Around three studies done on the incidence of postoperative hypothermia and associated factors for all patients who underwent surgery in 2014, as well as the incidence of perioperative hypothermia and associated factors for all patients who underwent surgery in 2015, were both the subject of studies at the Gondar University Hospital (GUH), and a study on the incidence of intraoperative hypothermia and associated factors for pediatric patients who underwent surgery in 2019 was conducted at the Tikur Anbessa Specialized Hospital 15 – 17 . since there has not been any prior research on the topic, the goal of this study is to ascertain the prevalence of intraoperative hypothermia and associated factors for pediatric patients undergoing surgery in the Ayder Comprehensive Specialized Hospital (Figure 1 ).…”

Background: Hypothermia is characterized by a drop in core body temperature of less than 36 °C. It occurs frequently throughout the operating period and affects surgical patient outcomes differently in terms of morbidity and mortality. Because of coagulopathy, metabolic acidosis, multiple organ failure, hemodynamic instability, and infections, a core temperature below 34 °C is strongly associated with mortality. Objective: This study aimed to assess the magnitude and associated factors of intra-operative hypothermia in pediatric patients undergoing elective surgery at the Ayder Comprehensive Specialized Hospital. Method: A prospective observational cross-sectional study was conducted on 399 pediatric patients undergoing elective surgery at Ayder Comprehensive Specialized Hospital in Tigray, Ethiopia, from May 1, 2023, to July 30, 2023. Participants in the study were selected by a systematic random sampling technique. The data collection procedure was chart review and intra-operative temperature measurement, and the collected data were analyzed by SPSS version 23. The independent variables were analyzed using binary and multi-logistic regression. The odds ratio, 95% confidence interval, and p-value of <0.05 were considered statistical significance. Result: The magnitude of intra-operative hypothermia was 52.9%. Neonate and infant [AOR: 6, 95% CI: 3.7, 9.8], (AOR=4.5, 95% CI: 2.9, 7) respectively, volume of fluid administered greater than half liter [AOR: 4.37, (95% CI, 3, 6.4)], patients who underwent surgery during the morning [AOR: 5.3, (95% CI: 3.8, 7.4)], and duration of surgery and anesthesia greater than 120 minutes [AOR: 2.7, (95% CI, 1.8, 4)] and (AOR=3.4, 95% CI, 2.4, 4.9], respectively, were factors significantly associated with intra-operative hypothermia. Conclusion and Recommendation: This study revealed a high magnitude of intraoperative hypothermia among pediatric patients. Being neonates and infants, having a cold volume of IV fluid administered greater than half a liter, entering surgery during the morning, the duration of surgery, and the anesthesia time were significantly associated with intra-operative hypothermia. We would like to advise anesthetists to use warm intravenous fluids, calculate IV fluids, and maintain room temperature.

INTRODUÇÃO:A hipotermia intraoperatória é definida como a temperatura central menor que 36°C, em pacientes com anestesia geral. Essa situação frequentemente está associada com fatores adversos como infecção pós-operatória, eventos cardiovasculares, hemorragia perioperatória e necessidade de transfusão. OBJETIVOS: Avaliar a hipotermia pós anestesia geral e elucidar os fatores de risco associados. METODOLOGIA: Trata-se de uma revisão integrativa na base de dados PUBMED utilizando os descritores “RISK AND HYPOTHERMIA AND ANESTHESIA AND GENERAL’’ para artigos publicados entre 2019 e 2024. RESULTADOS: A hipotermia intraoperatória (HI) possui uma prevalência de 39,8%, os neonatos e lactentes são estatisticamente mais associados à HI. Fatores como a temperatura ambiente do centro cirúrgico inferior a 26°C e a administração de mais de 1 litro de líquido ao paciente durante a cirurgia são fatores preditivos à hipotermia. Por outro lado, pacientes que possuem idade mais avançada (>66 anos) apresentam baixo limiar de vasoconstrição, facilitando diretamente a instalação do quadro hipotérmico nessa faixa etária. Além disso, o grau da cirurgia e complicações prévias como baixa temperatura corporal pré-operatória e combinação de anestesias locais e regionais também possuem grande significância na HI. CONCLUSÃO: A hipotermia apresenta alta prevalência nas cirurgias com anestesia geral, sendo os neonatos e lactantes os mais afetados. Cuidados pré-operatórios são fundamentais na prevenção.
