Temperature Monitoring Devices In Anaesthesia

Temperature and cardiac events.

Temperature monitoring devices in anaesthesia.

On average core temperature drops 1 1 5c in the first hour. Another reason for failing to monitor temperature is that fever is said to be a late sign of malignant hyperthermia. If a polychromatic infrared detector is used 7 13 um the monitor can automatically detect the anesthetic agent used as the absorption spectra at these wavelengths are relatively different. In addition temperature monitoring should be done on nearly every unconscious patient because of the rapid changes in temperature that can occur under anesthesia.

Palpation of a pulse auscultation of heart sounds monitoring of a tracing of intra arterial pressure ultrasound peripheral pulse monitoring or pulse plethysmography or oximetry. Mild hypothermia can delay recovery from anesthesia. Probes can be placed in the axilla in the pharynx or in the esophagus and indicate at the least temperature trending. Tympanic membrane pulmonary artery distal esophagus nasopharynx is used to monitor intraoperative hypothermia prevent overheating and facilitate detection of malignant hyperthermia because these sites are not necessarily available or convenient a variety of near core sites are also used clinically.

Specialized monitors for obtaining more detailed and complicated information mostly about the heart can also be used when useful or needed for certain types of surgeries. 4 2 3 every patient receiving general anesthesia shall have in addition to the above circulatory function continually evaluated by at least one of the following. Core temperature monitoring e g.
