肿胀液温度对吸脂术后受术者核心体温的影响

目的 探讨肿胀液温度对吸脂术后受术者核心体温的影响.方法 15例健康女性随机分为A、B两组,A组8例,肿胀液温度为室温25 ℃;B组7例,肿胀液温度为37 ℃.15例手术均采取硬膜外麻醉.统计分析术后0、1、2、3、4、8 h两组核心体温、呼吸频率、脉率和血压的差异.结果 A组术后0、1、2、3 h核心体温分别为(35.8±0.5)℃、(35.8±0.5)℃、(36.0±0.5)℃、(36.1±0.5)℃,B组为(36.5±0.4)℃、(36.5±0.3)℃、(36.5±0.3)℃、(36.6±0.4)℃,两组比较差异有统计学意义(P=0.008,P=0.008,P=0.03,P=0.033).两组术后4、8 h体温差异无统计学意义(P>0.05).两组受术者的呼吸频率、脉率和平均动脉压术后各时相点差异均无统计学意义(P>0.05).结论 吸脂术中应用低温肿胀液易导致受术者核心体温降低,增加手术风险,不利于术后康复.术中应用37 ℃的肿胀液是值得提倡的.

Effect of the tumescent infiltration solution temperature on body temperature

Objective To evaluate the effect of tumescent infiltration solution temperature on core body temperature after liposuetion. Methods 15 healthy female subjects were randomly divided into 2 groups to receive tumescent infiltration solution at 25 ℃ as group A, or at 37 ℃ as group B. All subjects were under epidural anesthesia. Vital signs, including core temperature, heart rate, respiratory rate and blood pressure, were monitored immediately, 1 hour, 2 hours, 3 hours, 4 hours and 8 hours after operation. Results The core body temperature immediately, 1 hour, 2 hours and 3 hours after operation were ( 35.8 ±0.5) ℃, (35.8±0.5)℃,(36.0±0.5) ℃,(36. 1±0.5)℃ in group A, and (36.5 ±0.4) ℃,(36.5±0.3) ℃,(36.5±0.3) ℃,(36.6±0.4) ℃ in group B, showing a significant difference between the two groups ( P = 0. 008, P = 0. 008, P = 0.03, P = 0. 033, respectively ). There was no difference in body temperature 4 hours and 8 hours after operation and in heart rate, respiratory rate and blood pressure between the two groups ( P > O. 05 ). Conclusions The tumescent infiltration solutions at room temperature (25 ℃ ) can decrease the core body temperature and increase surgical risk. It might not be good for rehabilitation. It is recommended to use tumescent infiltration solution at body temperature (37 ℃) in liposuction.
