Urban hypothermia and hyperglycemia in the elderly

From December 1993 to March 1999 we treated 18 elderly patients aged 66-87 years, suffering from urban hypothermia: 11 women and 7 men. Ten patients suffered from moderate hypothermia (rectal temperature 32-35 degrees C), and eight from severe hypothermia (rectal temperature < 32 degrees C). Regarding consciousness, in the group suffering from moderate hypothermia, 3 were somnolent and 6 in various degrees of comatose states. In the group suffering from severe hypothermia, 3 patients were somnolent or soporous and 5 in comatose states of various degrees. Values of arterial blood pressure in the group with moderate hypothermia was normal in one, in 3 arterial hypotension was observed and 6 were in a state of shock. In the group with severe hypothermia, 3 presented arterial hypotension and 5 were in a state of shock. In the group with moderate hypothermia the blood glucose level was elevated in six: 9.3-10.2-10.7-17.9-21.3-99.0, and in one patient the blood glucose level was low: 2.3 mmol/L, in correlation with hypoglycemic coma. In the group with severe hypothermia in all eight patients the values were elevated: 6.7-7.4-7.6-8.7-9.1-11.2-12.4-17.9 mmol/L.
