研究目的:

通过前瞻性研究,在驱动压(ΔP)指导下进行PEEP调节,比较不同通气模式(PCV-VG与VCV)对高体重指数(BMI≥40kg/m²)患者减重手术中呼吸力学(ΔP、Pplat、Ppeak、Cdyn)及氧合指数、肺部并发症(PPCs)的影响,以期可以实现术中ΔP降低,改善呼吸动力学指标,减少低氧及PPCs发生率。  

Objectives of Study:

This prospective study is aimed to investigate the impact of driving pressure (ΔP)-guided PEEP titration on respiratory mechanics (ΔP, Pplat, Ppeak, Cdyn), oxygenation index, and postoperative pulmonary complications (PPCs) in bariatric surgery patients with a body mass index (BMI) ≥40 kg/m², comparing pressure-controlled volume-guaranteed (PCV-VG) and volume-controlled ventilation (VCV). The primary objective is to optimize intraoperative ΔP reduction, enhance respiratory dynamics, and mitigate hypoxemia and PPC incidence.
