Padronização Do Exame Termográfico Nas Articulações Do Carpo E Matacarpofalangeanas De Cavalos Em Treinamento

Abstract

RESUMO:A termografia é um exame por imagem que consiste em captar as radiações térmicas emitidas por um corpo ou objeto e as transformar num mapa térmico da temperatura superficial dos mesmos. Por ser uma técnica recente em medicina veterinária, e não existirem valores de referência quanto à temperatura de estruturas anatômicas e temperatura ambiente, seu uso é limitado. Com o objetivo de determinar os valores de referência para temperatura da articulação do carpo e metacarpofalangeana do membro torácico direito (MTD), foram utilizados 45 equinos em treinamento da raça crioula, sadios, a temperatura foi aferida em dois períodos do dia (manhã e tarde). Foram também avaliados a correlação da variação da temperatura ambiente com as temperaturas da articulação do carpo MTD e MTE e a comparação da temperatura média das articulações metacarpofalangeana (MTD e MTE) articulação do carpo (MTD e MTE). As temperaturas para a articulação do carpo e articulação metacarpofalangeana apresentaram diferenças com a variação da temperatura ambiente. A comparação da temperatura média das articulações não demonstrou diferença significativa entre as temperaturas.

The use in veterinary medicine is limited, because this is a recent technique, few professionals have the thermal imager and there are no reference values, as anatomical structures and ambient temperatures. The aim of this study was to determine de reference values of carpal and the metacarpophalangeal joint, in the right forelimb. A total of 45 healthy Criollo breed horses in training were used, the measures was done in two periods of the day (morning and afternoon). There were also evaluated the correlation of temperature with ambient temperatures of the carpal joint of the right forelimb and left forelimb, and the comparison of the average temperature of the metacarpophalangeal joints and carpal, carpal joint and carpal, metacarpophalangeal joint and metacarpophalangeal. The carpal and metacarpophalangeal joint had differences with the variation of the environment temperature. The comparison of the average temperature of the joints showed no significant difference between the temperatures.

Thermographic assessment of skin and soft tissue tumors in cats

“…Studies in horses revealed positive correlations between increased joint and ambient temperature, emphasizing the need for examination in a temperature-controlled environment. 2,17 In this study, the analysis showed that a TA temperature above 34.7°C is significantly associated with the presence of malignancy, making thermography an auxiliary method in determining the prognosis. In humans, thermography is also used to facilitate tumor location and to distinguish between benign and malignant neoplasms, as malignant tumors tend to be warmer than benign lesions.…”

Termografia infravermelho da superfície abdominal ventral de coelhos (oryctolagus cuniculus) pré e pós-laparorrafia mediana com fios de quitosana ou poliglecaprone / Infrared thermography of ventral abdominal surface of rabbits (oryctolagus cuniculus) pre and post midline laparorrhaphy using chitosan or polyglecaprone yarns

“…In veterinary medicine, infrared thermography has been used in several studies as an auxiliary diagnostic method for pregnancy and estrous period 11 , viral 12 , bacterial 13 , and neoplastic 14 diseases, musculoskeletal injuries 15,16 , and also in the study of thermoregulation 17,18 and in the follow-up of wound healing process [19][20][21][22] . These uses may enable early and less invasive diagnosis of certain diseases 23,24 .…”

“…It has been used in several anatomical regions and in different species presenting good correlation with the traditional histological evaluation method. In this scenario, infrared equipment has been Brazilian Journal of Development, Curitiba, v.7, n.4, p. 35275-35292 apr 2021 used in equines 19,20 , dogs 25 , rats 22,26 , and rabbits 27 encompassing anatomical regions of knee joint 25 , heel region 27 , carpus 21 , metacarpus 19,20 , lower lip 22 , and lateral thoracic wall 19,22 . However, most studies that evaluated inflammatory processes using infrared thermography technique did not observe a preoperative evaluation to standardize cutaneous temperature 20,[27][28][29][30] .…”

“…However, most studies that evaluated inflammatory processes using infrared thermography technique did not observe a preoperative evaluation to standardize cutaneous temperature 20,[27][28][29][30] . Moreover, in referred literature 11,12,[19][20][21][22][23][24][25][26][27] , there are no reports of evaluating ventral abdominal surface temperature, pre or post-implantation of biomaterials, furthermore, few studies used healthy animals in regulated environment with controlled temperature, luminosity, humidity, and air currents 31 .…”
