During the process of animal surgery or acute anesthetized animal experiment, maintaining animals’ body temperature is very important for the accuracy and reliability of the results, furthermore, it is an important way to reduce the mortality of the animals. To fulfill this need, we have a new generation of homothermic monitoring system “Thermostar”, which is a closed-loop temperature monitor/control system for rodents. The system includes the control unit, 1 flexible rectal probe, 1 heating pad, and 1 heat insulation pad.
The Homeothermic monitoring system is controlled using a 4.3-inch color LCD touch screen, this user interface allows for a clear view of the subject’s real-time core body temperature, the target temperature, and heating state. Audible alarms can be set to alert the user for abnormalities in the subject’s core body temperature.
ConductScience offers the Homeothermic System.

A corresponding heat insulating pad is underneath every heating pad to prevent temperature loss.
The Heat and Temperature controller system, also known as the homeothermic monitoring system, is recurrently used for thermal regulation and monitoring in rodent surgeries. The normal body temperature of rodents ranges between 36.2-37.5ºC, whereas the cages in which they are housed have an ambient temperature of 23-24ºC. This difference in temperatures can result in hypothermia in rodents. Additionally, anesthetization and post-operative recovery from anesthesia can also cause hypothermia in rodents. A heat and temperature controller consisting of a thermal controller, a rectal probe, a heating pad, and a heat insulation pad is used for rodent thermoregulation in research laboratories.
Impaired thermoregulation resulting from general anesthesia during stereotaxic surgeries is the leading cause of hypothermia in rodents. In mammals, including rodents, the variations in core temperature are limited to +/- 0.3oC by the body’s autonomic and behavioral responses. This narrow temperature range is called the “inter-threshold range,” and the hypothalamus can extend this range 10-20fold, thus tolerating a fluctuation of (+/-) 2-4oC in body temperature. Anesthetics suppress the hypothalamus causing hypothermia before the beginning of any heat conservation mechanisms like vasoconstriction etc. Furthermore, control of arteriovenous shunting is lost due to the injection of general anesthesia. This loss of control causes heat redistribution from core to peripheral areas, ultimately decreasing core temperature. In a nutshell, hypothermia is induced as soon as the anesthesia is injected (Schuster and Pang, 2017). Therefore, one must take precautions beforehand to prevent it. For this, a heat and temperature control system is used.
The heat and temperature control system uses a rectal probe, also known as a thermal sensor, gently inserted into the rodent’s body via the rectal route to measure body temperature. A temperature controller with a digital display shows the temperature measured by the rectal probe. Additionally, a heating pad is used to overcome hypothermia, and the temperature controller also monitors its temperature.
The homeothermic monitoring system provided by Conduct Science is a closed-loop system that includes a flexible rectal probe that enables the digital temperature controller to collect real-time feedback from the heating pad, automatically controlling the rodent’s body temperature. The temperature controller (20.5×14.8×8.0cm) has an LCD that indicates the system’s current status, such as ‘heating,’ ‘stand-by,’ ‘warning,’ etc. The temperature scale can be interchanged between Fahrenheit and Celsius. Heating pads are made of high-quality silicone and efficiently provide warmth to the animals during surgery. They are available in three different sizes for rats, mice, and home cages. One can order them according to their experimental requirements. The homeothermic system has a temperature control range of 25-45ºC.
Following protocol can be followed using a heat and temperature control system (de Diego-García et al., 2019).
