目的 探讨光纤压力传感器(FOPT)直接气道压力监测在肺部手术中的应用及其临床意义.方法 30例行肺部手术的患者,根据术前肺功能情况分为肺功能正常组(14例)和肺功能异常组(16例),麻醉诱导气管插管后,将FOPT插入双腔气管导管的左右腔,所测压力分别为支气管压力和主气道压力,持续监测气道压力至术后30 min.观察围术期气道压力的变化.结果 单肺通气过程中,两组患者的主气道压力都随着单肺通气时间的延长而增加;肺功能正常组在单肺通气过程中各时间点的主气道压力的差异均无统计学意义(P值均>0.05),肺功能异常组在单肺通气90 min及结束时的主气道压力较单肺通气开始10 min时显著增加(P值均<0.05).双肺通气过程中,肺功能正常组术毕和术后30 min支气管压力和主气道压力与麻醉诱导后的差异均无统计学意义(P值均>0.05);肺功能异常组在术毕和术后30 min的支气管压力和主气道压力均较麻醉诱导后显著增加(P值均<0.05).结论 在肺部手术应用FOPT直接测压可及时反映气道的实际压力,有助于气道管理.术前肺功能异常患者术中易出现气道压力升高,且术后不易下降,这可能与肺损伤有关.
目的 探討光纖壓力傳感器(FOPT)直接氣道壓力鑑測在肺部手術中的應用及其臨床意義.方法 30例行肺部手術的患者,根據術前肺功能情況分為肺功能正常組(14例)和肺功能異常組(16例),痳醉誘導氣管插管後,將FOPT插入雙腔氣管導管的左右腔,所測壓力分彆為支氣管壓力和主氣道壓力,持續鑑測氣道壓力至術後30 min.觀察圍術期氣道壓力的變化.結果 單肺通氣過程中,兩組患者的主氣道壓力都隨著單肺通氣時間的延長而增加;肺功能正常組在單肺通氣過程中各時間點的主氣道壓力的差異均無統計學意義(P值均>0.05),肺功能異常組在單肺通氣90 min及結束時的主氣道壓力較單肺通氣開始10 min時顯著增加(P值均<0.05).雙肺通氣過程中,肺功能正常組術畢和術後30 min支氣管壓力和主氣道壓力與痳醉誘導後的差異均無統計學意義(P值均>0.05);肺功能異常組在術畢和術後30 min的支氣管壓力和主氣道壓力均較痳醉誘導後顯著增加(P值均<0.05).結論 在肺部手術應用FOPT直接測壓可及時反映氣道的實際壓力,有助于氣道管理.術前肺功能異常患者術中易齣現氣道壓力升高,且術後不易下降,這可能與肺損傷有關.

Objective To observe the airway pressure measured directly by the fiber optic pressure transducer in pulmonary surgery. Methods Thirty patients scheduled for elective pulmonary surgery were divided into two groups according to the pulmonary functions before operation=the normal pulmonary function group (n=14) and the abnormal pulmonary function group (n=16). After the double lumen tube insertion, the fiber optic pressure transducer was inserted into the left and right lumen: Pbronchi and Pairway. The airway pressure was measured continuously till 30 rain postoperatively by the fiber optic pressure transducer. Results During one-lung ventilation, Pairway was increased with time in both groups. But Pairway had no significant change in the normal pulmonary function group, and was significantly increased at 90 min after the beginning of one-lung ventilation and at'the end of one-lung ventilation in the abnormal pulmonary function group. During two-lung ventilation, there was no significant increase in Pbronchi and Pairway of the normal pulmonary function group, and those of the abnormal pulmonary function group were increased significantly at the end of the operation and 30 min after the operation. Conclusion The fiber optic pressure transducer can provide a direct airway pressure measurement, which is useful in airway management. In the pulmonary surgery, the airway pressure has more changes in patients with abnormal pulmonary function than in those with normal pulmonary function, which may be related to lung injury.
