研究目的:

本研究旨在从是否超声引导与操作方法两因素水平,全面比较超声引导与传统法、持续式(控制性肺膨胀法)与阶梯式(PEEP递增法)肺复张策略对肺部并发症中高危患者腹部手术后肺不张等临床、安全及医疗保健预后的影响,为建立围术期最佳肺复张策略提供证据。  

Objectives of Study:

We aimed to establish the optimal perioperative recruitment maneuvers in intermediate- or high-risk patients undergoing abdominal surgery by evaluating two modifications to traditional technique: ultrasound-guided versus conventional and stepwise versus sustained on postoperative atelectasis, as well as other clinical, safety, and health-care resource outcomes.

Group:

conventional sustained inflation

Sample size:

干预措施:

麻醉机设为手控通气模式,限压阀(APL)设为30cmH2O,手动挤压呼吸囊持续正压通气30s。

干预措施代码:

Intervention:

The recruitment manoeuvre was performed by manual inflation with a airway pressure of 30 cmH2O for 30 s.

Intervention code:

组别:

超声引导下持续式肺膨胀法肺复张组

样本量:

90

Group:

ultrasound-guided sustained inflation

Sample size:

干预措施:

LUS检查后将探头置于肺不张区域,在超声直接实时引导下进行肺复张;采用持续式肺膨胀法增加气道压力,直至超声图像中没有可见的塌陷肺区(最大气道压限制在40cmH2O、最大潮气量限制在20ml/kg)

干预措施代码:

Intervention:

The recruitment manoeuvre was performed under the direct real-time guidance of ultrasound. Manual inflation was applied until no collapsed areas were visible on the ultrasound. The maximum airway pressure was limited to 40 cmH2O, and the tidal volume of each recruitment manoeuvre was limited to 20 ml/kg.

Intervention code:

组别:

传统阶梯式(PEEP递增法)肺复张组

样本量:

90

Group:

conventional incremental PEEP

Sample size:

干预措施:

麻醉机设为PCV模式,I:E=1:1,初始气道压为15 cmH2O,PEEP从5 cmH2O开始,每30s递增5 cmH2O,直至PIP达30 cmH2O维持30s,随后逐级递减至基础通气参数

干预措施代码:

Intervention:

The recruitment manoeuvre was performed by maintaining a steady airway pressure of 15 cm H2O, with 5 cm H2O increments in PEEP until a peak airway pressure of 30 cm H2O was achieved. Each PEEP level was maintained for 30 s. The peak airway pressure was maintained for 30 sand subsequently reduced, followed by maintenance with the previous ventilator settings.

Intervention code:

组别:

超声引导下阶梯式(PEEP递增法)肺复张组

样本量:

90

Group:

ultrasound-guided incremental PEEP

Sample size:

干预措施:

术毕行肺超声检查后将探头置于肺不张区域,在超声直接实时引导下进行肺复张;采用PEEP递增法增加气道压力,直至超声图像中没有可见的塌陷肺区(最大气道压限制在40 cmH2O、最大潮气量限制在20ml/kg)。

干预措施代码:

Intervention:

The recruitment manoeuvre was performed under the direct real-time guidance of ultrasound; incremental PEEP was applied to increase the airway pressure until no collapsed areas were visible on the ultrasound. The maximum airway pressure was limited to 40 cmH2O, and the tidal volume of each recruitment manoeuvre was limited to 20 ml/kg.
