Esofagustemp

Esofagustemp is a term used to describe the measurement of temperature within the esophagus, typically obtained with a temperature-sensing probe. The esophageal temperature reading is commonly used as a proxy for core body temperature in various clinical settings. The term itself is not widely standardized in medical literature; in most sources the measurement is described as esophageal temperature or esophageal thermometry. When used, esofagustemp implies that temperature data are captured specifically from the distal esophagus via a nasogastric or orogastric thermistor probe.

Measurement is usually performed with a probe that contains a thermistor or thermocouple. The device is inserted through the nose or mouth and advanced to the distal esophagus, typically around the level of the lower third of the thorax, depending on patient height. Esophageal temperature readings correlate closely with core body temperature and tend to respond rapidly to changes in the patient’s heat balance. Compared with skin or oral temperatures, esophageal measurements are often less influenced by ambient room conditions and can provide a more reliable assessment of true core temperature during dynamic clinical situations.

Clinical applications include monitoring during general anesthesia to detect hypothermia or hyperthermia, and in critical care or perioperative settings where precise core temperature management is important. Esophageal thermometry is also used during therapeutic rewarming after hypothermia and in certain surgical or trauma contexts.

Limitations include the need for placement of a probe, with associated risks such as mucosal injury or infection, and potential unreliability in patients with esophageal pathology or improper probe positioning. As a term, esofagustemp remains less common than the standard nomenclature esophageal temperature.
