目的 观察腹腔镜胃癌根治术病人术中功能残气量(FRC)和动脉血气分析的变化,研究长时间气腹对全麻后肺萎陷的影响。方法 选择择期行腹腔镜胃癌根治术病人30例。分别于诱导气管插管后10min(T0)、气腹后30min(T1)、气腹后60min(T2)、、2h(T3)、3h(T4)抽取病人桡动脉血行血气分析,记录PH值、动脉血氧分压(PaO2)、动脉血气CO2分压(PaCO2);同时采用密闭式氦稀释法测量FRC。结果 与T0比较,T1、T2、T3时,病人FRC明显降低(P<0.01);与T3比较,T4时病人FRC差异无统计学意义(P>0.01)。与T0比较,T1时PaO2无统计学差异(P>0.01),T2、T3时明显降低(P<0.01),与T3比较,T4时病人PaO2差异无统计学意义(P>0.01)。结论 长时间气腹可加重全麻后肺萎陷,并导致PaO2降低。 |

Abstract: |
objective To study the effect of long time pneumoperitoneum on atelectasis after general anesthesia by means of observation the changes of the functional residual capacity and arterial blood gas in patients undergoing laparoscopic radical gastrectomy for gastric cancer. Methods We studied 30 patients undergoing laparoscopic radical gastrectomy for gastric cancer. Arterial blood samples were taken 10 min after induction of anesthesia(T0), 30min(T1)、60min(T2)、2h(T3)、3h(T4) after pneumoperitoneum,. Recored PH, PaO2, PaCO2, FRC (closed-circuit helium dilution method) was measured at the same times. Results Compare with T0, FRC were significantly decreased in T1、T2、T3(P<0.01). Compare with T3, there was no statistical difference in FRC between patients in T4(P>0.01). Compare with T0, there was no statistical difference in PaO2 between patients in T1(P>0.01),while PaO2 were significantly decreased in T2、T3(P<0.01).Conclutions Long time pneumoperitoneum can aggratate atelectasis after general anesthesia, and decrease PaO2. |
