目的：观察俯卧位手术时患者 PaCO2和 PET CO2的变化并进行相关性分析。方法选择40例脊柱手术患者,ASA Ⅰ或Ⅱ级,监测全麻诱导后仰卧位时 PaCO2与PET CO2的值作为基础值(T0),再调整为俯卧位,分别监测并记录俯卧位后30 min(T1)、60 min(T2)和90 min(T3) PaCO2与PET CO2,分析 PaCO2与PET CO2的相关性并对各时点 PaCO2(y)和PET CO2(x)进行曲线拟合求出方程,计算动脉血-呼气末二氧化碳分压差(Pa-ET CO2)。结果全麻诱导后仰卧位及术中俯卧位时PET CO2与 PaCO2有显著的相关性,T0~T3时相关系数分别为 r 0=0.84,r 1=0.88,r 2=0.84和 r 3=0.82(P <0.01)。T0~T3时Pa-ET CO2分别为(5.3±2.1)mm Hg、(6.6±2.1)mm Hg、(5.8±2.2)mm Hg和(5.9±2.1)mm Hg。T0~T3时 PaCO2(y)和PET CO2(x)的方程分别为 y0=1.1 x0+2.5、y1=1.1 x1+2.3、y2=1.1 x2+2.4、y3=1.1 x3+4.6。结论无论仰卧位还是俯卧位,PET CO2与 PaCO2相关性较好,Pa-ET CO2总体变化范围为3.7~8.7 mm Hg,俯卧位时PET CO2可以作为评估 PaCO2的指标。

Objective To investigate the correlation between arterial carbon dioxide partial pressure (PaCO2 )and end-tidal carbon dioxide partial pressure (PET CO2 )in prone position operation and calculate the value of PaCO2 according to the PET CO2 .Methods Forty patients with ASA Ⅰ orⅡ undergoing spinal surgery were selected,and the values of PaCO2 and PET CO2 as basic value (T0 ) after induction of general anesthesia in supine position monitor and record the value of PET CO2 and PaCO2 in prone position after 30 min (T1 ),60 min (T2 )and 90 min (T3 ).The correlation between PaCO2 and PET CO2 in each time point were analyzed,and the equation of PaCO2 (y)and PET CO2 (x) with curve fitting and difference of PaCO2 and PET CO2 were calculated.Results There was significant correlation between PaCO2 and PET CO2 in the supine and prone position,their correlation coefficients were r 0 =0.84,r 1 =0.88,r 2 =0.84,r 3 =0.82 (P <0.01).The Pa-ET CO2 was (5.3±2.1)(T0 )in supine position and (6.6± 2.1 )mm Hg (T1 ),(5.8 ± 2.2 )mm Hg (T2 ),(5.9 ± 2.1 )mm Hg (T3 )in prone position.The equation in each time point PaCO2 (y)and PET CO2 (x)were y0 =1.1 x0 +2.5,y1 =1.1 x1 +2.3,y2 =1.1 x2 +2.4,y3 =1.1 x3 +4.6,and the Pa-ET CO2 was 3.7-8.7 mm Hg. There was no significant difference between PaCO2 and PET CO2 at T1-T3 .Conclusion Whenever in prone position or supine position,PET CO2 and PaCO2 have significant correlation in prone position and supine position.The overall range of Pa-ET CO2 is 3.7-8.7 mm Hg,and the PET CO2 can be as indica-tor to estimate PaCO2 in prone position.
