During surgical procedures, maintaining stable vital signs is a core objective of anesthesia management. Body temperature, a fundamental yet clinically valuable physiological parameter, directly impacts the balance of multiple physiological systems, including metabolism, circulation, and coagulation. Intraoperative hypothermia can prolong postoperative recovery time and increase the risk of complications such as infection, bleeding, and arrhythmias. Therefore, continuous and accurate temperature monitoring to inform anesthesia management has become an indispensable safety measure in modern operating rooms. Temperature probes are key devices in this process.

Temperature probes enable real-time monitoring of core body temperature, which is particularly clinically significant in prolonged surgeries or those involving open body cavities. Compared to traditional intermittent measurements, temperature probes use thermistors to rapidly convert temperature changes into electrical signals that are transmitted to the monitoring system, enabling continuous curve monitoring. This immediacy facilitates anesthesiologists' assessment of the patient's current condition and allows for the timely detection of potential risks arising from abnormal temperature changes. For example, during surgery, the use of cold irrigation, anesthetic drugs causing suppression of the thermoregulatory center, or when a large exposed area is present, the patient may experience a sustained drop in body temperature. By analyzing the temperature trend provided by the temperature probe, the anesthesia team can promptly implement warming measures, such as using warming blankets or administering warm intravenous fluids, effectively preventing the adverse consequences of hypothermia.

Regarding the selection of temperature probes, esophageal or rectal probes are generally preferred for intraoperative monitoring. These two types are closer to the core temperature response zone, providing more representative data. Esophageal probes are more commonly used in patients undergoing intubation anesthesia, as they can be stably fixed in the thoracic esophagus, reducing measurement interference; while rectal probes are suitable for patients who cannot be intubated, such as those undergoing local anesthesia or pediatric anesthesia. In contrast, skin-type temperature probes are generally not the first choice for monitoring core body temperature during surgery due to their susceptibility to ambient temperature fluctuations.

The unique intraoperative environment also places higher demands on the performance of temperature probes. Probes need to have rapid response capabilities to provide accurate feedback at the initial stage of changes in patient temperature; they should also have good anti-interference performance to avoid signal fluctuations caused by electrosurgical units, high-frequency equipment, or changes in patient position. Furthermore, the probe's structural design must consider ease of intraoperative operation and patient comfort. Flexible cables, precise and compact temperature-sensing heads, and excellent interface compatibility with monitors are all crucial for ensuring the quality of intraoperative data.

From an anesthesia management perspective, the use of temperature probes is not only reflected in intraoperative monitoring but also throughout preoperative preparation and postoperative observation. For example, probes can be pre-set before anesthesia induction to reduce mid-operative interference; maintaining the probe connection when the patient is transferred to the recovery room after surgery helps monitor postoperative hypothermia recovery and, if necessary, extend warming intervention. This integrated continuous monitoring process provides reliable support for hospitals to improve perioperative management.

With increased awareness of infection control, the usage rate of disposable temperature probes in anesthesiology departments has been increasing year by year. Their characteristics of requiring no cleaning, ease of use, and reduced risk of cross-infection make them particularly suitable for high-turnover, high-risk surgical environments. For institutions equipped with comprehensive cleaning and disinfection systems, reusable probes can also achieve a balance between performance and cost.

In conclusion, temperature probes are not merely monitoring tools in intraoperative anesthesia management but also essential components for ensuring patient safety, optimizing anesthesia protocols, and reducing postoperative complications. Through proper selection, standardized use, and comprehensive management, body temperature probes will continue to play an irreplaceable role in modern operating rooms, contributing to the continuous improvement of medical quality and patient care.
