Abstract
The physical examination has several stages, one of which is the measurement of body temperature, when it exceeds the physiological values is indicative of some disease or hyperthermia, for this in veterinary medicine the mercury or digital thermometer is commonly used. The objective of this work is to compare if there is a difference between the mercury thermometer and the infrared thermometer or digital thermometer, as well as to identify if there is a difference between the measurement locations with the infrared thermometer and the mercury column thermometer and digital thermometer. Infrared temperature was evaluated in three places: oral mucosa, pinna and anal or vaginal mucosa (females), then a digital thermometer, followed by mercury, which was used as a reference standard. There was a statistical difference between the mercury thermometer and the infrared thermometer, when measured on the anal or vaginal mucosa and on the oral mucosa. The infrared thermometer, in the ear, and the digital thermometer did not differ from the mercury thermometer, demonstrating that these present similar values during the temperature measurement. The infrared thermometer proved to be little invasive and fast when compared to the others. However, some limitations were observed in the measurement of body temperature with the infrared thermometer measured in the ear. It is concluded that the infrared thermometer, used in the ear, and the digital thermometer are equivalent to the mercury thermometer and can be used in horses, however, more studies on this topic are still needed.
Highlights
The measurement of body temperature is an important step in the physical examination of the patient
The objective of this work is to compare if there is a difference between the mercury thermometer and the infrared thermometer and the digital thermometer, in the verification of the body temperature of horses, as well as to identify if there is a difference between the measurement places with the infrared thermometer and the thermometer column of mercury and digital thermometer, having as standard the mercury thermometer
The horses were placed in stalls where they remained for 30 minutes, since immediately before the beginning of the body temperature measurements, the ambient temperature was measured using an infrared thermometer (G-TECH)
Summary
The measurement of body temperature is an important step in the physical examination of the patient. In addition to being a low-invasive method, when it exceeds physiological values, it may be indicative of some infectious process. Since the rise in body temperature is one of the main clinical signs present in infectious processes. Hyperthermia can occur when there is an increase in temperature without being. Acta Veterinaria Brasilica March 15 (2021) 82-86. Of inflammatory origin, such as dehydration, exercise and high ambient temperature (FEITOZA, 2014). Like other domestic species, maintain their body temperature within certain limits, even with variations in environmental conditions (REED; BAYLY; SELLON, 2017). Normal body temperature can vary between 37.2 to 38.2 °C (CUNNINGHAM, 1999)
