目的 研究单肺通气麻醉胸腔镜手术对幼猪血流动力学及动脉血气的影响。方法 选取健康家猪 8只 ,体重 (7 1± 0 7)kg。吸入 1%异氟醚维持麻醉 ,颈部气管切开行左主支气管插管。通过Swan Ganz漂浮导管和动脉导管动态监测血流动力学及动脉血气变化。结果 单肺通气后平均肺动脉压 (mPAP)从 (15 8± 1 5 )mmHg(1mmHg =0 133kPa)升至 (19 5± 2 3)mmHg(P <0 0 5 ) ,血氧饱和度、动脉血气及其它血流动力学指标无明显变化。结论 幼猪可以较好地耐受单肺通气麻醉胸腔镜手术目的 研究单肺通气麻醉胸腔镜手术对幼猪血流动力学及动脉血气的影响。方法 选取健康家猪 8只 ,体重 (7 1± 0 7)kg。吸入 1%异氟醚维持麻醉 ,颈部气管切开行左主支气管插管。通过Swan Ganz漂浮导管和动脉导管动态监测血流动力学及动脉血气变化。结果 单肺通气后平均肺动脉压 (mPAP)从 (15 8± 1 5 )mmHg(1mmHg =0 133kPa)升至 (19 5± 2 3)mmHg(P <0 0 5 ) ,血氧饱和度、动脉血气及其它血流动力学指标无明显变化。结论 幼猪可以较好地耐受单肺通气麻醉胸腔镜手术
Objective To study the effects of single-lung ventilation anesthesia thoracoscopic surgery on hemodynamics and arterial blood gas in young pigs. Methods Eight healthy pigs were selected and weighed (71 ± 0 7) kg. Inhalation of 1% isoflurane to maintain anesthesia, tracheotomy left main bronchial catheterization. Hemodynamic and arterial blood gas changes were monitored dynamically by Swan Ganz floating catheter and arterial catheter. Results The mean pulmonary arterial pressure (mPAP) increased from 15 8 ± 1 5 mmHg (1 mmHg = 0 133 kPa) to (19 5 ± 2 3) mmHg after single lung ventilation (P <0 05) No significant changes in blood gas and other hemodynamic parameters. Conclusion The piglets can be well tolerated by one-lung ventilation anesthesia for thoracoscopic surgery Objective To investigate the effects of one-lung ventilation anesthesia thoracoscopic surgery on hemodynamics and arterial blood gas in young pigs.
