摘要
目的 :探讨上腹部手术不同麻醉方法对心率变异性 (HRV)的影响。方法 :30例择期上腹部手术患者分为全麻复合硬膜外腔麻醉 (CA)组和全麻 (GA)组。测定麻醉前 (T0 )、气管插管后 5 m in(T1)、腹腔探查时 (T2 )、术中 1h(T3)和 2 h(T4)、术毕拔气管导管前 (T5 )和拔气管导管后 15 min(T6 )的 HRV。结果 :与 T0相比 ,CA组标化低频值 (L Fnorm)在 T2 ,T3,T4,T5和 T6均显著降低 (P<0 .0 1) ,L F/ HF在 T1,T2 ,T3和 T4也均显著降低 (P<0 .0 1)。 GA组围麻醉期 HRV的各项数据均无显著变化。组间比较 ,CA组 L Fnorm在 T3显著低于 GA组 (P<0 .0 5 ) ,L F/ HF在 T3和 T4也显著低于 GA组 (P<0 .0 5 )。结论 :全麻下行上腹部手术心脏自主神经功能稳定 。
AIM:To investigate the effect on cardiac autonomic reflex on patients who suffer upper abdominal surgery under combination of general and epidural anesthesia (CA) or general ansethesia (GA). MEHTODS:30 adult patients with elective upper abdominal surgery were assigned to receiving CA or GA. Change of the heart rate varibility (HRV) were measured before anesthesia (T0), at 5 min after trachea intubation (T1),exploring abdomen (T2),at 1nd hour (T3),2nd hour(T4) during operation,at the moment before extubation (T5) and 15 minute after extubation (T6). RESULTS:As compared with those at T0,LFnorm was significantly decreased at T2,T3,T4,T5 and T6 ( P <0.01),LF/HF reduced markedly at T1,T2,T3 and T4 ( P <0.05), but HFnorm,TP,HF and LF were no significant change at group CA. During perioperation at group GA, studied data kept statistically unchanged ( P >0.05). As compared with those in group GA,LFnorm reduced dramatically at T3,and LF/HF also reduced markedly at T3 and T4. CONCLUSION:HRV at group GA is stable, but sympathetic nerve is inhibited at group CA.
