摘 要:目的:探讨肺保护通气策略在胸腹腔镜食管癌根治术中的临床价值。方法:采用前瞻性研究方法。选取2015年6月至2016年6月新疆医科大学附属肿瘤医院收治的160例行胸腹腔镜食管癌根治术患者的临床病理资料。采用随机数列法将患者分为试验组和对照组。两组患者均行胸腹腔镜食管癌根治术,术中均行单腔气管导管辅以CO2人工气胸。试验组患者术中机械通气采用肺保护性通气策略模式,通气参数:[潮气量(VT)6 mL/kg+适当呼气末正压(PEEP)5 cmH2O(1 cmH2O=0.098 kPa)+限制气道平台压(Pplat)≤30 cmH2O+肺复张];对照组患者术中采用传统通气模式(通气参数:VT=9 mL/kg)。观察指标:设定观察时间点为术中气管插管后10 min(T1)、单肺通气1 h(T2)、手术完毕时(T3)、术后24 h(T4)。(1)呼吸力学指标比较:气道峰压(Ppeak)、Pplat、气道阻力(Raw)。(2)血气分析指标比较:PaO2、PaCO2、pH。(3)炎性反应指标比较:IL-6、IL-8、TNFα、C反应蛋白。(4)术后肺部并发症比较:记录术后肺部感染、肺不张、肺水肿、支气管痉挛、低氧血症、ARDS。正态分布的计量资料以±s表示,组间比较采用成组t检验。计数资料比较采用χ^2检验。等级资料采用非参数秩和检验。重复测量数据采用重复测量 方差分析。结果:筛选出符合研究条件的患者160例。试验组与对照组各80例。(1)呼吸力学指标 比较:试验组和对照组患者Ppeak由T1时相点变化至T3时相点分别为(18.5±3.4)mmHg(1 mmHg= 0.133 kPa)-(22.5±4.6)mmHg和(17.2±3.7)mmHg-(32.5±4.8)mmHg,Pplat变化分别为(15.3±3.6)mmHg-(17.5±2.7)mmHg和(15.1±3.8)mmHg-(21.5±4.5)mmHg,Raw变化分别为(15.1± 1.8)cmH2O/(L·s)-(16.8±2.6)cmH2O/(L·s)和(15.6±2.8)cmH2O/(L·s)-(19.5±4.0)cmH2O/(L·s),两组患者上述指标变Objective:To explore the clinical value of the lung protective ventilation strategy in thoracoscopic and laparoscopic radical resection of esophageal cancer. Methods:The prospective study was conducted. The clinicopathological data of 160 patients who underwent thoracoscopic and laparoscopic radical resection of esophageal cancer at the Tumor Hospital Affiliated to Xinjiang Medical University between June 2015 and June 2016 were collected. All the patients undergoing thoracoscopic and laparoscopic radical resection of esophageal cancer were allocated respectively into the experimental group and control group according to the random number table, and intraoperative singlelumen endotracheal tube intubation and continuous CO2 artificial pneumothorax was conducted. Patients in the experimental group received mechanical ventilation using lung protective ventilation strategy. Parameters of mechanical ventilation: tidal volume (VT) 6 mL/kg+positive end expiratory pressure (PEEP) 5 cmH2O (1 cmH2O=0.098 kPa)+plat pressure (Pplat)≤30 cmH2O+recruitment maneuver (RM). Patients in the control group received the traditional ventilation (parameters of ventilation: VT=9 mL/kg). Observation indicators: observation points were at 10 minutes after tracheal intubation in general anesthesia (T1), at 1 hour after onelung ventilation (T2), at the end of surgery (T3) and at 24 hours postoperatively (T4). (1) Comparison of parameters of respiratory mechanic: peak airway pressure (Ppeak), Pplat and resistance of airway (Raw) . (2) Comparison of the blood gas analysis: arterial oxygen partial pressure (PaO2), arterial carbon dioxide partial pressure (PaCO2) and pH. (3) Comparison of inflammatory reaction indexes: serum IL-6, IL-8, TNFα and Creactive protein. (4) Comparison of postoperative pulmonary complications: pulmonary infection, pulmonary atelectasis, pulmonary edema, bronchospasm, hypoxemia and acute respiratory distress syndrome (AR
