Objectives: this study aimed at estimating and comparing the reliability of temperature measurements obtained using a peripheral infrared temporal thermometer, a central cutaneous thermometer ("Zero-Heat-Flux Cutaneous thermometer") and an esophageal or nasopharyngeal thermometer among elective surgical patients in the intraoperative period. Method: a longitudinal study with repeated measures carried out by convenience sampling of 99 patients, aged at least 18 years old, undergoing elective abdominal cancer surgeries, with anesthesia lasting at least one hour, with each patient having their temperature measured by all three methods. Results: the intraclass correlation coefficient showed a low correlation between the measurements using the peripheral temporal thermometer and the central cutaneous (0.0324) and esophageal/nasopharyngeal (-0.138) thermometers. There was a high correlation (0.744) between the central thermometers evaluated. Conclusion: the data from the current study do not recommend using infrared temporal thermometers as a strategy for measuring the body temperature of patients undergoing anesthetic-surgical procedures. Central cutaneous thermometers and esophageal/nasopharyngeal thermometers are equivalent for detecting intraoperative hypothermia.
Objetivos: el objetivo de este estudio fue estimar y comparar la confiabilidad de mediciones de temperatura obtenidas por medio de un termómetro temporal infrarrojo periférico, un termómetro cutáneo central ("Termómetro cutáneo Zero-Heat-Flux ") y un termómetro esofágico o nasofaríngeo en pacientes sometidos a cirugías electivas durante el período intraoperatorio. Método: estudio longitudinal con mediciones repetidas llevado a cabo con una muestra por conveniencia de 99 pacientes, de al menos 18 años de edad, sometidos a cirugías electivas por cáncer abdominal, con anestesia de al menos una hora de duración, y midiendo la temperatura de cada paciente con los tres métodos. Resultados: el coeficiente de correlación intraclase indicó una correlación baja entre las mediciones realizadas con el termómetro temporal periférico y los termómetros cutáneo (0,0324) y esofágico/nasofaríngeo (-0,138) centrales. Se registró una correlación alta (0,744) entre los termómetros centrales evaluados. Conclusión: los datos del presente estudio no recomiendan utilizar termómetros temporales infrarrojos como estrategia para medir la temperatura corporal de pacientes sometidos a procedimientos anestésico-quirúrgicos. Los termómetros cutáneos centrales y los esofágicos/nasofaríngeos son equivalentes para detectar hipotermia intraoperatoria.

Abstract This study aimed to evaluate the influence of temperature on torsional strength and angular deflection of two experimental NiTi rotary instruments manufactured from Blue and Gold thermal treatments and with identical cross-sections. A total of 40 experimental NiTi instruments 25.06 and with a triangular cross-section and manufactured from Blue and Gold thermal treatments were used (n=20). The torsional test was performed in the 3 mm from the tip of the instrument according to ISO 3630-1. The torsional test evaluated the torsional strength and angular deflection to failure at room temperature (21°C ± 1° C) and body temperature (36°C ±1°C). The fractured surface of each fragment was observed by using scanning electron microscopy (SEM). Data were analyzed using an unpaired t test for inter and intra-group comparison and the level of significance was set at 5%. The results showed that the body temperature did not affect the torsional strength and angular deflection of the instruments when compared with room temperature (P>0.05). However, at body temperature, the Blue NiTi instruments presented significantly lower angular deflection in comparison with Gold NiTi instruments (P<0.05). There was no significant difference regarding the torsional strength of the instruments at body temperature (P>0.05). The temperature did not affect the torsional strength of the instruments manufactured from Blue and Gold technology. However, the Blue NiTi instruments presented significantly lower angular deflection than Gold instruments at 36°C temperature.
Resumo O objetivo deste estudo foi avaliar a influência da temperatura nas propriedades de torção (resistência à torção e deflexão angular) de dois instrumentos rotatórios experimentais de NiTi fabricados com secção triangu.ar e tratamentos térmicos Blue e Gold. Quarenta instrumentos experimentais de NiTi 25.06 com tratamento térmico Blue e Gold foram usados (n= 20). Foi avaliada a resistência torcional e a deflexão angular até a fratura na temperatura ambiente (21°C ± 1°C) e corporal (36°C ± 1°C). O teste torcional foi realizado nos 3 mm da ponta dos instrumentos de acordo com a ISO 3630-1. A superfície fraturada de cada instrumento foi observada pelo microscópio eletrônico de varredura (MEV). Os dados foram analisados por meio do teste t não pareado para a comparação inter e intragrupos e o nível de significância à 5%. Os resultados demonstraram que a temperatura corporal não afetou a resistência a torção e deflexão angular quando comparada com a temperatura ambiente (P>0.05). No entanto, na temperatura de 36°C o instrumento com tratamento térmico Blue apresentou menor deflexão angular quando comparado com o Gold (P<0.05). Não houve diferença significante entre os dois instrumentos em relação a resistência à torção. A temperatura corporal não modificou a resistência torcional dos instrumentos fabricados com tecnologia Blue e Gold. No entanto, os instrumentos com NiTi Blue apresentaram menor deflexão angular do que o Gold a 36°C.

Perioperative neurocognitive disorders(PND)is a common complication after surgery or anesthesia, especially in elderly patients.The effects and mechanism of body temperature on PND are still controversial.In this paper, the relationship between body temperature and PND and its possible mechanism of action were discussed based on some research results of perioperative body temperature management in elderly patients, aiming at suggesting the significance of body temperature management in preventing PND.
ABSTRACT
Objective:To investigate the effect of intraoperative body temperature on prognosis of elderly patients with strangulated small bowel obstruction.Methods:The clinical data of 113 elderly patients with strangulated small intestinal obstruction and perform partial resection and anastomosis admitted to the Affiliated Hospital of Southwest Medical University from December 2017 to June 2022 were retrospectively analyzed. The ROC curve was used to analyze the relationship between the intraoperative body temperature(T) and the prognosis of patients, so as to obtain the optimal cutoff point (Ta). According to the relationship between T and Ta, all patients were divided into hypothermia group (33 cases) (T<Ta) and hyperthermia group (80 cases)(T ≥ Ta), and the differences in prognosis between the 2 groups were compared and Logistic regression was applied to analyze the influence of prognostic factors.Results:The optimal cutoff value (Ta ) of ROC curve was 36.45℃. The incidence of postoperative complications in hypothermia group was 60.6% (20/33), higher than 6.3%(5/80) in hyperthermia group ( χ2=40.06, P<0.01). Multivariate analysis by Logistic regression revealed that enteric perforation and lower intraoperative body temperature were risk factors for surgical prognosis ( OR=9.874, 95% CI 1.260-77.400; OR=69 865.637, 95% CI 90.799-53 758 097.700, both P<0.05). Conclusions:Intraoperative body temperature was a factor affecting surgical prognosis in elderly patients with strangulated small bowel obstruction. The temperature lower than 36.45 ℃ during the operation indicated that the patients were more prone to complications and had worse prognosis. Intensive temperature management was required intraoperatively in elderly patients, and nursing interventions such as warming and heating blankets were necessary.
ABSTRACT
Objective:To observe the different administration methods of methoxamine on the body temperature protection of patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods:The clinical data of 278 patients underwent OPCABG from January 2019 to December 2021 in Jinzhou Central Hospital were retrospectively analyzed, and the patients were used the methoxamine during the operation. Among them, 157 cases were given methoxamine by continuous intravenous infusion (continuous intravenous infusion group), and 121 cases were given methoxamine by fractional intravenous infusion in stages (fractional intravenous infusion group). The changes of mean arterial pressure (MAP) and heart rate during operation were recorded, and the fluctuation rate of MAP was calculated. The dosage of methoxamine, use time of variable temperature blanket, time from the end of operation to waking up and occurrence of adverse reactions such as hypothermia, rigors, coagulation disorders and renal insufficiency were recorded.Results:During anesthesia, the fluctuation rate of MAP in continuous intravenous infusion group was significantly lower than that in fractional intravenous infusion group: (16.62 ± 3.17)% vs. (23.53±3.69)%, and there was statistical difference ( P<0.05). The MAP and heart rate of continuous intravenous infusion group were more stable at each time point than that of fractional intravenous infusion group. The use time of variable temperature blanket, and incidences of hypothermia, rigors in continuous intravenous infusion group were significantly lower than those in fractional intravenous infusion group: (86.17 ± 19.66) min vs. (146.72 ± 29.37) min, 2.55% (4/157) vs. 9.92% (12/121) and 1.91% (3/157) vs. 8.26% (10/121), and there was statistical difference ( P<0.01 or <0.05); there were no statistical differences in dosage of methoxamine, time from the end of operation to waking up and incidence of coagulation disorders between two groups ( P>0.05); Renal insufficiency did not occur in both groups. Conclusions:Continuous intravenous pumping of methoxamine can obviously reduce the heat loss of human body, enhance the insulation effect of other insulation measures, and reduce the incidence of hypothermia in patients underwent OPCABG.

ABSTRACT
ABSTRACT Introduction There are slight differences in heart rate variation (HRV) between athletes from different sports, and different exercise loads justify the most important reason for this slight difference in HRV. Objective To study the detection of heart rate and body temperature in adolescents by physical training. Methods Twelve young basketball players were randomly selected. Heart rate variability and body temperature indicators were collected before starting the sports intervention activity, lasting four weeks in a specific protocol. After the intervention period, the participant's heart rate variability indicators and body temperature indicators were collected again. In an attempt to understand physical function training using comparative analysis and data processing obtained before and after the exercise intervention. Results A high increase in blood circulation velocity after exercise is directly proportional to the increase in body temperature. After four weeks of training, the heart rate of the 12 athletes increased from 92.35±3.65 to 84.77±5.13 beats per minute. Conclusion Body temperature can rise from the average temperature of 36.5°C before training to 36.7°C. The maximum temperature of 37°C can be reached within 5 minutes after stopping activity. The increasing intensity in physical function training can effectively improve the Standard deviation of the average normal RR intervals and root mean square velocity in the domain index in heart rate variability.

ABSTRACT
Objective:To evaluate the effects of different temperature management strategies on blood-brain barrier (BBB) and postoperative cognitive dysfunction (POCD) in the patients undergoing spinal fixation surgery.Methods:Ninety-six patients, aged 44-78 yr, weighing 45-104 kg, of American Society of Anesthesiology physical status Ⅰ-Ⅲ, undergoing spinal fixation surgery with combined intravenous-inhalational anesthesia, were divided into 3 groups ( n=32 each) by the simple randomization: warming blood transfusion and infusion group (group WBI), active warming group (group AW) and active warming plus selective brain cooling group (group SBC). In WBI group, the fluid for intraoperative intravenous infusion was warmed to 37 ℃ using a medical blood transfusion-infusion warmer.In AW group, warming was maintained using the fluid warming combined with the body surface warming blanket until the end of operation, and the target temperature of the warming blanket was set at 38 ℃.In SBC group, the warming protocol were similar to those previously described in AW group, and selective brain cooling was performed through an electronic ice cap with a set temperature of 4 ℃.Blood samples were collected from the median cubital vein at the end of operation, brain microvascular endothelial cells were isolated and identified by immunomagnetic bead, and the target cells were counted with a fluorescence microscope.The concentration of C-reactive protein in peripheral blood was measured by rate nephelometry on the first day after operation.The extubation time, length of post-anesthesia care unit (PACU) stay, total length of hospital stay, thermal comfortableness score, shivering in PACU, agitation and postoperative fever were recorded.The postoperative recovery was assessed using the 40-item Quality-of-Recovery scale on 7th day after surgery. Results:Compared with WBI group, the incidence of POCD and shivering in PACU, extubation time, length of PACU stay, and serum C-reactive protein concentrations were significantly decreased, and thermal comfortableness score and 40-item Quality-of Recovery scale score were increased in AW group and SBC group ( P<0.05). Compared with AW group, the count of brain microvascular endothelial cells was significantly decreased in SBC group ( P<0.05). Conclusions:Active warming produces no damage to the structure of BBB, and can reduce the development of POCD; active warming combined with selective brain cooling can improve the structural integrity of BBB, but it cannot reduce the development of POCD in the patients undergoing spinal fixation surgery.

Por lo tanto, se efectuó un estudio cuantitativo, con diseño preexperimental de preprueba/posprueba con un solo grupo entre enero y junio del 2019 en un Programa Canguro Ambulatorio de Bogotá. Resultados: Se acogieron un total de 63 bebés canguro. Se realizó análisis estadístico con SPSS, descriptivo e inferencial con prueba de normalidad de Kolmogorov-Smirnov y métodos paramétricas t-student y no paramétricas Friedman. La frecuencia cardiaca presentó un aumento en el índice siendo la media inicial de 147.22±7.17 lpm y de 147.54±7.96 lpm después de la intervención, aunque este no fue significativo (p=0.603). Por su parte, la oximetría presentó un aumento al ser la mediana inicial de 92% y después del MBC 93% variación que fue significativa (p=0.000). Finalmente la temperatura inicial y después presentó una mediana de 36.6°C con un índice inicial de 36.59±0.169°C y de 36.62±0.163°C después de la intervención, aunque este no fue significativo (p=0.182). Se realizó un modelo de regresión ajustado a las variables fisiológicas no encontrandose factores predictores estadísticamente significativos. Desde el modelo de Callista Roy el MBC tuvo una respuesta adaptativa eficaz. Conclusiones: La técnica de MBC tiene un efecto favorable y seguro en la frecuencia cardiaca, saturación de oxigeno y temperatura sin alteración de los parámetros normales con buena adaptación según el modelo de Callista Roy.
The purpose of this research was to measure the physiological response (heart rate, oxygen saturation and temperature) of the premature or low birth weight child, with the application of the "Kangaroo Baby MassageKBM" technique. , with the aim of demonstrating the safety of this technique in these physiological parameters in the newborn. Therefore, a quantitative study, with a pre-experimental pre-test/post-test design, was carried out with a single group between January and June 2019 in a Kangaroo Outpatient Program in Bogotá. Results: A total of 63 kangaroo babies were received. Statistical analysis was performed with SPSS, descriptive and inferential with the Kolmogorov-Smirnov normality test and parametric tstudent and non-parametric Friedman methods. The heart rate presented an increase in the index, the initial mean being 147.22±7.17 bpm and 147.54±7.96 bpm after the intervention, although this was not significant (p=0.603). On the other hand, oximetry showed an increase as the initial median was 92% and after the KBM was 93%, a variation that was significant (p=0.000). Finally, the temperature presented initial and after median 36.6°C an increase with an initial index of 36.59±0.169°C and 36.62±0.163°C after the intervention, although this was not significant (p=0.182). A regression model adjusted to the physiological variables was performed, and no statistically significant predictive factors were found. From Callista Roy's model, the KBM had an effective adaptive response. Conclusions: The KBM technique has a favorable and safe effect on heart rate, oxygen saturation and temperature without alteration of normal parameters with good adaptation according to the Callista Roy model.

Objective: To investigate the effect of room and body temperatures on cyclic fatigue resistance of three endodontic nickel-titanium rotary files: Hyflex EDM (HEDM) (Coltene/Whaledent, Switzerland), WaveOne Gold (WOG) (Dentsply Maillefer, Switzer), and EdgeOne Fire (EOF) (EdgeEndo, Albuquerque, New Mexico, USA) in a double- curved canal. Material and Methods: In this study, Sixty NiTi rotary files were used. These files were divided into three groups (n = 20 for each group). Group A: HEDM (size 25, taper 0.08), group B: WOG (size 25, taper 0.07), and group C: EOF (size 25, taper 0.07). Each group was subdivided into two subgroups (n=10 for each subgroup). One of the subgroup was subjected to cyclic fatigue test at room temperature (20±1°C), while the other subgroup was subjected to cyclic fatigue test at body temperature (37±1°C). These files were tested by using a custom-made artificial canal with a double curvature (coronal curve: 60° curvature with 5 mm radius; apical curve: 70° curvature with 2 mm radius). All instruments were rotated according to the manufacturer instructions until the fracture occurred by using electric endodontic motor (Wave One, Dentsply Maillefer, Ballaigues, Switzerland). The number of cycles to fracture (NCF) and the fractured fragment length (FL) were recorded for each endodontic file. The data were gathered and statistically analyzed using shapiro-wilk test and two-way ANOVA test. The statistical significance was set at 0.05. Results: The NCF of WOG and EOF were significantly lower at body temperature as compared to room temperature (p ≤ 0.05), whereas no difference was observed in NCF of HEDM at body and room temperatures (p>0.05). At 20±1°C, the results showed a non-significant difference between NCF of WOG and EOF (p>0.05), while the NCF of HEDM was significantly lower than the other groups (p ≤ 0.05). At 37±1°C, the results showed a non-significant difference in NCF among the tested endodontic files (p ≤ 0.05). There is non-significant difference in FL of each group at (20±1°C) and (37±1°C) (p>0.05). No statistical difference in FL among the tested files at room and body temperatures (p>0.05). Conclusion: The temperature has a significant effect on cyclic fatigue resistance of EOF and WOG, whereas no effect was observed on cyclic fatigue resistance of HEDM. WOG and EOF had a comparable NCF, while HEDM had a lower NCF than other groups at room temperature. At body temperature, all tested files have a comparable NCF. These results were attributed to the type of the alloy and heat treated that was used to manufacture these endodontic files. The cyclic fatigue test should be done at body temperature (AU)
Objetivo : Investigar o efeito das temperaturas ambiente e corpórea na resistência a fadiga cíclica em três instrumentos endodônticos rotatório de níquel-titânio: Hyflex EDM (HEDM)(coltene/Whaledent, Switzerland), WaveOne Gold (WOG) Dentsply Maillefer, Switzer), e EdgeOne Fire (EOF) (EdgeEndo, Albuquerque, New Mexico, USA) em canais com dupla curvatura. Material e Métodos : Neste estudo foram utilizadas sessenta limas endodônticas rotatórias. Esses grupos foram divididos em três grupos (n=20). Grupo A: HEDM (tamanho 25, conicidade 0.08), grupo B: WOG (tamanho 25, conicidade 0.07), e grupo C: EOF (tamanho 25, conicidade 0.07). Cada grupo foi subdivididos em dois subgrupos (n=10). Um dos subgrupos foi submetido ao teste de fadiga cíclica em temperatura ambiente (20±1°C), enquanto o outro subgrupo foi submetido a ao teste de fadiga cíclica em temperatura corpórea (37±1°C). Essas limas foram testadas em um canal artificial feito sob medida com duas curvaturas (curva coronal: curvatura de 60º e com 5 mm de raio; curva apical: curvatura de 70º com 2mm de raio); Todos os instrumentos foram rotacionados de acordo com a instrução do fabricante até que a fratura ocorresse utilizando um motor endodôntico elétrico (Wave One, Dentsply Maillefer, Ballaigues, Switzerland). O número de ciclos até a fratura (NCF) e a comprimento do fragmento fraturado (FL) foram registrados para cada lima endodôntica. Os dados foram coletados e analisados pelo teste shopiro-wilk e ANOVA two-way. A significância estatística foi 0.05. Resultados: O NCF do WOG e do WOF foi significantemente menor na temperatura corpórea em comparação à temperatura ambiente (p ≤ 0.05), enquanto não foi observada diferença entre NCF em HEDM em temperatura corpórea e temperatura ambiente (p>0.05). Em 20±1°C, os resultados mostraram diferença não significativa entre o NFC com WOG e EOF (p>0.05), enquanto o NCF com HEDM foi significante menor que os demais grupos (p ≤ 0.05). A 37±1°C, os resultados mostraram diferença não significativa em NCF entre as limas endodônticas testadas (p ≤ 0.05). Há diferença não significativa no FL de cada grupo (20±1°C) e (37±1°C) (p>0.05). Não houve diferença estatisticamente diferente no FL entre as limas testadas nas temperaturas ambiente e corporal (p>0,05). Conclusão: A temperatura tem efeito significativo na resistência a fadiga cíclica do EOF e WOG, enquanto não foi observado nenhum efeito na resistência a fadiga cíclica do HEDM. WOG e EOF tiveram um NCF comparável, enquanto HEDM teve um NCF menor do que os outros grupos em temperatura ambiente. À temperatura corporal, todas as limas testas apresentam semelhante NCF. Esses resultados foram atribuídos ao tipo de liga e ao tratamento térmico que foi utilizado na fabricação. O teste de fadiga cíclica deve ser feito à temperatura corporal (AU)

Abstract Infrared thermography (IRT) has been used to assess skin temperature (Tsk), especially during the COVID-19 pandemic, as an important tool in medical screening not only of the general population, but also of young athletes. However, the subcutaneous adipose tissue can act as an insulator when the Tsk is assessed by IRT, modifying the normal Tsk data and leading to their misinterpretation. Considering that the body mass index (BMI) is an important predictor of obesity, the objective of this study was to verify if the Tsk measured by IRT is affected by the BMI in adolescents. A preliminary study was carried out being four participants intentionally selected, all 16 years old, each one classified in a different BMI range according to the criteria of the World Health Organization for the adolescent population: underweight, healthy weight, overweight and obesity. Four thermograms of each participant were recorded and the ThermoHuman® software was used to evaluate 82 regions of interest (ROI), which were integrated into 6 body regions. Using healthy weight subjects as a reference, it was found a progressive reduction in Tsk in all ROI compared to overweight and obese participants, with emphasis on the anterior region of the trunk (3.04% and 6.69% less respectively), and an increase in the Tsk of all body regions for the underweight subject. There are indications that BMI can influence the Tsk value in adolescents and should be taken into account when analyzing thermograms for a correct evaluation of thermal normality.
Resumo A termografia infravermelha (TI) tem sido uma técnica empregada para avaliar a temperatura da pele (TP), especialmente durante a pandemia do COVID-19. Contudo, existem indicações que o tecido adiposo subcutâneo pode agir como uma camada isolante, alterando o comportamento da TP, o que pode dificultar a interpretação da normalidade térmica. Tendo em vista que o índice de massa corporal (IMC) é considerado um importante preditor de obesidade, o objetivo deste estudo foi verificar se a TP sofre interferência de diferentes classificações de IMC em adolescentes. Foram selecionados 4 participantes de maneira intencional, todos com 16 anos, cada um foi classificado em uma diferente faixa de IMC para população de adolescentes segundo a classificação proposta pela Organização Mundial de Saúde para essa idade: baixo peso, peso normal, sobrepeso e obesidade. Foram feitos quatro termogramas, avaliados no software ThermoHuman®, que avalia 82 regiões corporais de interesse (RCI), que foram integradas em 6 regiões corporais. Utilizando os indivíduos com peso normal como referência, foi encontrada uma redução progressiva na TP comparada aos participantes com sobrepeso e obesidade, com ênfase para a região anterior de tronco (3.04% e 6.69% menores, respectivamente), e um aumento na TP de todas as regiões corporais comparadas ao sujeito com baixo peso. Isso indica que o IMC pode influenciar nos valores da TP em adolescentes e deve ser levado em consideração para uma avaliação correta da normalidade térmica.

ABSTRACT
Resumo Objetivo Comparar o tempo de execução do banho no leito pelo método tradicional e a seco e seus efeitos sobre as alterações oxi-hemodinâmicas em pacientes críticos. Métodos Ensaio clínico randomizado crossover, aberto, com 50 pacientes submetidos aos dois tipos de banho no leito: tradicional e a seco. Avaliou-se o tempo de execução dos banhos e as variáveis oxi-hemodinâmicas (temperatura timpânica e axilar, saturação de oxigênio arterial, frequência respiratória, frequência cardíaca e pressão arterial média), obtidas no início dos banhos, aos dez minutos, no início e no fim da lateralização dos pacientes, ao final do procedimento e 15 minutos depois. Para análise utilizou-se Teste T de Student pareado e modelo de equações de estimação generalizadas. Resultados O banho no leito a seco foi executado em menor tempo que o tradicional (18,59 versus 26,45 minutos; p<0,001). No banho tradicional, ao longo do tempo, houve redução da temperatura axilar e elevação da frequência respiratória (p<0,001). No banho a seco, apenas a temperatura axilar sofreu alteração, tornando-se menor que o valor inicial (p<0,001). Conclusão O banho a seco foi superior ao tradicional em decorrência do menor tempo de execução e menor instabilidade oxi-hemodinâmica dos pacientes entre os períodos observados. A monitorização dos pacientes é fundamental para identificar tais alterações.
Resumen Objetivo Comparar el tiempo de ejecución del baño en cama mediante el método tradicional y a seco y sus efectos sobre las alteraciones oxihemodinámicas en pacientes críticos. Métodos Ensayo clínico aleatorizado crossover, abierto, con 50 pacientes sometidos a dos tipos de baño en cama: tradicional y a seco. Se evaluó el tiempo de ejecución de los baños y las variables oxihemodinámicas (temperatura timpánica y axilar, saturación del oxígeno arterial, frecuencia respiratoria, frecuencia cardíaca y presión arterial promedio), obtenidas al comienzo de los baños, a los diez minutos, al comienzo y al final de la lateralización de los pacientes, al final del procedimiento y 15 minutos después. Para el análisis se utilizó el Test-T de Student pareado y el modelo de ecuaciones de estimación generalizadas. Resultados El baño en cama a seco fue ejecutado en menor tiempo que el tradicional (18,59 versus 26,45 minutos; p<0,001). En el baño tradicional, a lo largo del tiempo, hubo reducción de la temperatura axilar y elevación de la frecuencia respiratoria (p<0,001). En el baño a seco, solo la temperatura axilar estuvo alterada, fue menor que el valor inicial (p<0,001). Conclusión El baño a seco fue superior al tradicional como consecuencia del menor tiempo de ejecución y menor inestabilidad oxihemodinámica de los pacientes entre los períodos observados. El monitoreo de los pacientes es fundamental para identificar tales alteraciones.
Abstract Objective To compare the bed bath execution time using the traditional and dry method and its effects on the oxy-hemodynamic changes in critically ill patients. Methods This is a crossover, open, randomized clinical trial, with 50 patients submitted to two types of bed bath: traditional and dry. The duration of the baths and the oxy-hemodynamic variables (tympanic and axillary temperature, arterial oxygen saturation, respiratory rate, heart rate and mean arterial pressure), obtained at the beginning of the baths, at ten minutes, at the beginning and at the end of patient lateralization, at the end of the procedure and 15 minutes later. Paired Student's t-test and generalized estimating equations model were used for analysis. Results Dry bed bath was performed in less time than the traditional bath (18.59 versus 26.45 minutes; p<0.001). In traditional bath, over time, there was a reduction in axillary temperature and an increase in respiratory rate (p<0.001). In the dry bath, only the axillary temperature changed, becoming lower than the initial value (p<0.001). Conclusion Dry bath was superior to the traditional one, due to the shorter time of execution and lesser oxy-hemodynamic instability of patients between the periods observed. Monitoring patients is essential to identify such changes.

Subarachnoid hemorrhage (SAH) is a common and serious type of stroke. Studies have shown that multimodal monitoring of brain temperature, intracranial pressure and cerebral blood flow is helpful for the perioperative management of patients with SAH, and further improves the outcomes of patients. This article reviews the brain temperature changes and mechanism after SAH as well as the role of mild hypothermia treatment.
ABSTRACT
Objective:To investigate the clinical efficacy and adverse reactions of linezolid in the treatment of gram-positive coccal infections after chemotherapy in older adult patients with leukemia.Methods:Ninety-two older adult patients with leukemia complicated by gram-positive coccal infections, who received treatment in Yiwu Central Hospital from January 2017 to December 2019, were included in this study. They were randomly assigned to receive routine anti-infection treatment (control group, n = 46) or linezolid treatment (observation group, n = 46). Clinical efficacy, the time required for body temperature restoring to normal, and medication time were compared between the two groups. Results:Total response rate was significantly higher in the observation group than in the control group [95.65% (44 /46) vs. 78.26% (36/46), χ2 = 6.13, P = 0.013]. The time required for body temperature restoring to normal and medication time in the observation group were (7.98 ± 1.04) days and (8.58 ± 1.31) days, respectively, which were significantly shorter than those in the control group [(8.85 ± 1.47) days, (9.46 ± 2.52) days, t = 3.27, 2.10, P = 0.001, 0.019). The incidence of adverse reactions was significantly lower in the observation group than in the control group [4.35% (2/46) vs. 19.57% (9/46), χ2 = 5.05, P < 0.05]. Conclusion:Linezolid is highly effective on gram-positive coccal infections after chemotherapy in older adult patients with leukemia. Linezolid treatment requires comparatively shorter time required for body temperature restoring to normal and shorter medication time and is safer than routine anti-infection treatment.
