| ［摘要］目的 探讨容量控制通气（VCV）、压力控制通气（PCV）和压力控制通气-容量保证（PCV-VG）这3种不同通气模式对老年胸外科手术患者呼吸和循环的影响．方法 36例择期开胸手术老年患者，随机均分为VCV、PCV和PCV-VG组．分别记录术前，OLV后20、40、60 min及恢复双肺通气后20 min时患者血流动力学、通气和动脉血气的各项参数．结果 PCV和PCV-VG组患者的Ppeak值明显低于VCV组（P＜0.05），而PCV和PCV-VG组之间比较，患者的Ppeak值无明显差异（P＞0.05）．在OLV 后40 min时PCV和PCV-VG组患者的PaO2高于VCV组（P＜0.05）．PCV-VG组患者PaO2较高，但与PCV组比较，在OLV期间并无明显改善（P ＞0.05）．结论 胸外科老年患者手术实施OLV时，使用PCV和PCV-VG通气模式可提高动脉氧合作用和降低气道压力，较VCV通气模式更具有显著的优点． |

| ［Abstract］Objective The aim of this study was to explore the effects of volume controlled ventilation （VCV），pressure controlled ventilation（PCV）and pressure controlled ventilation-volume guaranteed （PCV-VG）on respiration and circulation in elderly patients undergoing thoracic surgery. Methods Thirty-six elderly patients who underwent thoracic surgery were enrolled in our study. Patients were divided into VCV， PCV and PCV-VG groups according to randomized design. The hemodynamic and respiratory data and the arterial blood gases had been recorded in the pre-operation，20 min，40 min，60 min after OLV and 20 min after the resumption of two lung ventilation. Results Compared with VCV group，Ppeak value was significantly lower in PCV and PCV-VG groups （P < 0.05）， and the difference was not found between the PCV and PCV-VG groups. PaO2 levels in PCV and PCV-VG groups were higher than that in VCV group after the point of OLV+40 （P < 0.05）. Comparison of PCV group， PaO2 in PCV-VG group was higher， but did not show a significantly improved during OLV（P > 0.05）. Conclusion Compared with VCV， the use of PCV and PCV-VG have significant advantages in the operative oxygenation and airway pressure for elderly patients undergoing OLV. |
