Abstract

【Abstract】Objective To investigate the influence of radiofrequency energy on body temperatures of patients with general anesthesia as scanning with super-high strength magnetic resonance (3.0 T) at peri-anesthesia stage. Methods There were 30 patients given general anesthesia for magnetic resonance during superhigh strength radiofreguency energy.According to the times of scanning with magnetic resonance during the operation,all patients were divided into 3 groups:once exposured group (Ⅰ),twice exposured group (Ⅱ) and 3 times exposured group (Ⅲ).Body temperature (armpit) were recorded before the induction (T0),one hour after the induction (T1),at the end of the last scanning (T2) and at the end of the operation (T3). Results Body temperatures at T2 and T3 were higher than those at T0 and T1 in each group,while body temperatures at T2 and T3 in group Ⅲ were higher than those in group Ⅰ and group Ⅱ (P<0.05). Conclusions Radio frequency energy of magnetic resonance with super-high strength may increase body temperature of patients with general anesthesia.
