Postcordotomy dysesthesia was classified from the clinical features of dysesthesia following percutaneous cervical cordotomy (PCC) in 66 patients. Dysesthesia occurred in 10 (15.2%) of 66 patients and was classified into three types. In the first type, dysesthesia occurred at the region where pain had been before PCC, and pain sensitivity had been lost due to PCC. ⋯ In the third type, dysesthesia occurred at the region where pain had been before PCC and pain sensitivity had partially recovered. This type of dysesthesia occurred in 3 patients. The reduction of the effect of PCC was presumably the cause of this type of dysesthesia.

The relative accuracy of Thermoscan PRO-1 (Thermoscan, USA), an infrared ear thermometer, in an unadjusted mode was examined in 21 patients under general anesthesia, using the esophageal and tympanic membrane temperatures as the reference values. The correlation coefficient between the temperature measured by Thermoscan PRO-1 and the esophageal temperature, and that between the temperature measured by Thermoscan PRO-1 and the tympanic membrane temperature, were 0.953 and 0.942, respectively (P < 0.01). The "limits of agreement" between the temperature measured by Thermoscan PRO-1 and esophageal temperature, and between the temperature measured by Thermoscan PRO-1 and tympanic membrane temperature, were -0.5-0.4 degrees C and -0.5-0.5 degrees C, respectively. We conclude that Thermoscan PRO-1 is sufficiently reliable for monitoring body temperature during surgery.
