An oesophageal probe (1) for measuring anaesthesia comprises means (4), for example a water-filled balloon, for sensing pressure in the oesophagus, and means (5), for example an air filled balloon, for stimulating the oesophagus to cause contractions therein.

摘要:
A method of monitoring the depth of anaesthesia of a patient, comprising stimulating contractions in the oesophagus of the patient, for example using an inflatable oesophageal balloon 5, obtaining signals indicative of the oesophageal contractions using a sensor 21, 4, and deriving from the signals an output indicative of the rate of occurrence of signals having a magnitude greaterthan a preset threshold value, and apparatus for carrying outthe method. An alternative aspect comprises assigning a score value to each of a plurality of different bodily functions of a patient, for example heart rate, blood pressure, degree of sweating, and formation of tears, the said score values being indicative of a depth of anaesthesia or sedation, summing the score values, and producing an output from the summed score values indicative of the amount of anaesthetic to be fed to the patient.
