Summary
Background. Anaesthesia and surgery may lead to significant core hypothermia, especially in the elderly. The aim of the study was to measure core and skin temperatures during combined general and combined general-epidural anaesthesia in elderly patients. Methods. 113 patients, aged 70±4 years, of both sexes, scheduled for thoracic tumour surgery, were allocated to two groups. The 74 patients in group A received general opioid-midazolam-nitrous oxide anaesthesia. In the 39 patients of group B, epidural catheters were introduced via the Th₄ -Th5 interspace prior to induction and subsequent general anaesthesia was similar. The core and superficial temperatures were measured at induction and at 30, 60, 90, 120, 150, 180 and 210 minutes after. Results. In both groups significant hypothermia was observed, but there were no differences between the two groups. The core temperatures in groups A and B at the designated times were: 36.1±0.4 vs. 36.1±0.4; 35.8±0.6 vs. 35.7±0.5; 35.5±0.6 vs. 35.5±0.5; 35.4±0.6 vs. 35.5±0.6; 35.5±0.6 vs. 35.5±0.6; 35.4±0.7 vs. 35.5±0.7; 35.2±0.7 vs. 35.6±0.7; 35.4±0.6 vs 35.6±0.7, respectively. Conclusions. Elderly patients become hypothermic during prolonged surgery, regardless of the method of anaesthesia used. Careful monitoring and the use of a heating system are recommended.
