摘要目的:探讨糖尿病因素对患者七氟烷肺摄取的影响。方法:选择择期行全麻手术的2型糖尿病患者20例为糖尿病组(D组)，年龄40~64岁，BMI 18.5~22.9 kg/m 2，ASA分级Ⅰ或Ⅱ级，并选择年龄、性别及手术均相匹配的非糖尿病择期手术患者20例为对照组(C组)。麻醉诱导气管插管术后，吸入七氟烷，吸入浓度2%(氧流量2 L/min)。于吸入七氟烷1、3、5、10、15、20、30 min时记录吸入浓度(Fi)和呼出浓度(Fa)，并计算Fa/Fi比值。记录Fa/Fi比值达0.7所需时间。 结果:与C组比较，D组各时点Fa/Fi比值升高，Fa/Fi比值达0.7所需时间缩短( P<0.05)。 结论:糖尿病因素可减少患者七氟烷肺摄取。

abstractsObjective:To investigate the effect of diabetes mellitus on pulmonary uptake of sevoflurane.Methods:Twenty patients with type 2 diabetes mellitus, aged 40-64 yr, with body mass index of 18.5-22.9 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, undergoing elective surgery with general anesthesia, served as diabetes group (group D). Twenty non-diabetic patients matched by age, gender and surgery were selected as control group (group C). After anesthesia induction and tracheal intubation, sevoflurane was inhaled at a concentration of 2% (oxygen flow 2 L/min). The inhaled concentration (Fi) and exhaled concentration (Fa) at 1, 3, 5, 10, 15, 20 and 30 min of inhalation of sevoflurane were recorded, and the Fa/Fi ratio was calculated.The time required for the Fa/Fi ratio to reach 0.7 was recorded. Results:Compared with group C, the Fa/Fi ratio was significantly increased at each time point, and the time required for the Fa/Fi ratio to reach 0.7 was shortened in group D ( P<0.05). Conclusion:Diabetes mellitus can reduce pulmonary uptake of sevoflurane in the patients.
