药物成份或治疗方案详述: |
拟选取宁夏医科大学总医院普胸外科择期行肺叶切除术的患者60例,随机分为常规组(C组)和驱动压滴定组(P组)。两组患者均于静脉全麻诱导后在可视喉镜下行双腔支气管插管,连接麻醉机行机械控制通气,两组均采用容量控制通气。插管完成后手法肺复张行双肺通气:潮气量(VT)为8ml/kg(PBW,男性 :PBW (kg)=0.905× [身高(cm)-152.4]+50;女性:PBW(kg)=0.905×[身高(cm)-152.4]+45.5),PEEP 5 cmH2O ,呼吸频率(RR)12次/min,吸呼比(I:E)1:2,FiO2=1, 氧流量设置2 L/min。 打开胸膜前开始行单肺通气,C组在单肺通气开始后设置5 ml/kg(PBW),PEEP 5 cmH2O ,呼吸频率(RR)12~18次/min,维持PETCO2在35~45 mmHg,吸呼比(I:E)1:2,FiO2=80%, 氧流量设置2 L/min。P组在单肺通气开始后根据驱动压滴定最佳潮气量,从8 ml/kg(PBW)开始设置潮气量,滴定期间RR为12次/分,每次设置维持5个呼吸周期,最后一个呼吸周期记录平台压,计算驱动压(△P);以25 ml为一个梯度,重复操作直到VT降至4 ml/kg(PBW)。将△P在12-15 cmH2O之间VT/△P比值最大时对应的VT作为最佳的VT,维持整个单肺通气过程。若排除双腔管位置不当、套囊过度充气的因素外,△P仍然大于15 cmH2O,选择最小△P对应的潮气量。此过程在5分钟内完成。其他呼吸机参数与C组保持一致。 使用丙泊酚、右美托咪定、瑞芬太尼进行麻醉维持。于患者双肺通气10 min(T0)、单肺通气15 min (T1)、单肺通气30 min(T2)、单肺通气60 min(T3)、恢复双肺通气10 min(T4)、拔管后60 min (T5) 抽取桡动脉血行血气分析,记录T0-5血气分析结果的动脉血氧分压(PaO2)、氧合指数(0I=PaO2 /FiO2)。记录或计算T0-4的平台压(Pplat)、峰压(Ppeak)和驱动压(△P)和动态顺应性(Cdyn),并记录术中低氧血症和术后肺部并发症(术后3天及术后1月门诊随访胸部CT检查)的发生情况。 |

Description for medicine or protocol of treatment in detail: |
60 patients scheduled for pulmonary lobectomy in Department of Thoracic Surgery, General Hospital of Ningxia Medical University were randomly divided into conventional group (Group C) and driving pressure titration group (Group P).Patients in both groups were intubated with double-lumen endobronchial tube under video laryngoscope after induction of intravenous anesthesia, and were connected to anesthesia machine for mechanical controlled ventilation.Two-lung ventilation was performed by manual lung recruitment after intubation:Tidal volume (VT) was 8ml/kg (PBW, male:PBW (kg)=0.905× [height (cm)-152.4]+50;Female:PBW(kg)=0.905×[height (cm)-152.4]+45.5), PEEP 5 cmH2O, respiratory rate (RR) 12 breaths/min, I: E ratio (I:E) 1:2, FiO2=1, oxygen flow setting 2 L/min.One-lung ventilation was performed before opening pleura. In group C, after the start of one-lung ventilation, 5 ml/kg (PBW), PEEP 5 cmH 2O, respiratory rate (RR) 12~18/min, PETCO2 maintained at 35~45 mmHg, I:E 1:2, FiO2= 80%, oxygen flow set at 2 L/min.in group P, that optimal tidal volume was titrate from 8 ml/kg (PBW) according to the drive pressure after OLV, and the RR was 12 bpm during the titration period.Repeat in 25 ml steps until VT drops to 4 ml/kg (PBW).The VT corresponding to the maximum VT/△P ratio between 12 and 15 cmH 2O was taken as the optimal VT to maintain the whole one-lung ventilation process.If the △P is still greater than 15 cmH2O, excluding the factors of improper position of double-lumen tube and over-inflation of cuff, the tidal volume corresponding to the minimum △P is selected.This process is completed within 5 minutes.Other ventilator parameters remained the same as in group C.Anesthesia was maintained with propofol, dexmedetomidine, and remifentanil.Blood gas analysis was performed at 10 min after two-lung ventilation (T0), 15 min after one-lung ventilation (T1), 30 min after one-lung ventilation (T2), 60 min after one-lung ventilation (T3), 10 min after resuming two-lung ventilation (T4) and 60 min after extubation (T5). PaO2 and oxygenation index (0I =PaO2 /FiO2) were recorded.The plateau pressure (Pplat), peak pressure (Ppeak), driving pressure (△P) and dynamic compliance (Cdyn) of T0-4 were recorded or calculated, and the occurrence of hypoxemia during operation and postoperative pulmonary complications were recorded. |
