Clinical study on effects of perioperative low temperature to regaining consciousness of the severe traumatic patients with general anesthesia

Abstract

Objective The explore the effects of perioperative low temperature to regaining consciousness of the severe traumatic patients with general anesthesia. Methods 60 cases of severe traumatic surgery patients, with stochastic double blind method, were divide into two groupg, 30 cases in control group adopted conventional processing,30 cases of heat preservation group took the positive low temperature preventive measures, the conditions of awakening time, shiver during consciousness time, dysphoria and hypotension were observed in the awakening period after general anesthesia. Results There was no significant difference between the body temperature at each time point of heat preservation group and that at the anesthesia beginning(P＞ 0.05), but when compared to that in the control group,there was significant difference (P＜ 0.05); in the control group, 7 cases of consciousness were found in 30 minutes after anesthesia, 16 cases found in 30 to 60 minutes, 7 cases in more than 60 minutes. While in the heat preservation group, 7 cases of consciousness were found in 30 minutes after anesthesia, 22 cases found in 30 to 60 minutes, 1case in more than 60 minutes. There was no significant difference in consciousness conditions 30 minutes after anesthesia(P＞ 0.05), there was significant difference in those of 30 to 60 minutes after anesthesia(P＜ 0.05), and there was very significant difference in those of 60 minutes after anesthesia(P ＜ 0.01). The data of shiver after consciousness (18 cases in control, 7 in heat preservation group), dysphoria (12 in control, 3 in heat preservation group) and hypotension (17 in control, 5 in heat preservation group) after anesthesia in these two groups had very significant differences(P＜ 0.01). Conclusion The perioperative low temperature can make great damage to severe traumatic patients, it will improve the general anesthesia quality, reduce the complications during conscious period,and raise the survival rate of the patients to make active measures for preventing the perioperative low temperature.
