Effect of Mechanical Power-based Lung-protective Ventilation During One-lung Ventilation

2026年8月25日 更新者:Heejoon Jeong、Samsung Medical Center

Incidence of Postoperative Pulmonary Complications Between Mechanical Power-based Versus Conventional Lung Protective Ventilation During One-lung Ventilation: a Randomized Controlled Trial

The goal of this clinical trial is to determine whether a mechanical power-based lung-protective ventilation strategy during one-lung ventilation reduces the incidence of postoperative pulmonary complications in adult patients undergoing lung resection surgery.

Mechanical power during pressure-regulated volume control mode is calculated using the formula below.

Mechanical power (J/min) = 0.098 x respiratory rate x tidal volume x (inspiratory airway pressure above positive end-expiratory pressure + positive end-expiratory pressure)

The main questions it aims to answer are:

  • Does a mechanical power-based lung-protective ventilation strategy significantly lower the incidence of major postoperative pulmonary complications compared to conventional ventilation?
  • How does this strategy impact intraoperative hemodynamic and vital profiles (e.g., blood pressure, cardiac output, vasopressor requirements, and blood oxygen saturation) during one-lung ventilation?

Participants will:

  • Be randomized to receive either a mechanical power-based lung-protective ventilation strategy or a conventional lung-protective ventilation strategy exclusively during one-lung ventilation.
  • Be closely monitored for the occurrence of major postoperative pulmonary complications (atelectasis, pneumonia, acute respiratory distress syndrome, and pulmonary aspiration) and adverse events for 1 month postoperatively.

武器和干预

参与者组/臂
干预/治疗
实验性的:Mechanical power-based lung protective ventilation group
Patients in this group will receive the mechanical power-based lung-protective ventilation strategy during one-lung ventilation.

Initial Settings

1) Tidal Volume: 4-6 mL/kg of predicted body weight 2) Positive End-Expiratory Pressure: Set to the value that minimizes driving pressure 3) Respiratory Rate: Adjusted to maintain an end-tidal carbon dioxide of 35-45 mmHg Protocol

  1. If mechanical power exceeds 7 J/min, decrease the respiratory rate by 1 and reduce the tidal volume by 5%, then maintain these settings for 1 minute.
  2. If mechanical power remains above 7 J/min after 1 minute, further decrease the respiratory rate by 1 and reduce the tidal volume by an additional 5%, then maintain for 1 minute.
  3. If end-tidal carbon dioxide exceeds 50 mmHg, perform arterial blood gas analysis to check arterial pH.
  4. If arterial pH drops below 7.2, the intervention will be discontinued, and the patient will be withdrawn from the study and treated with conventional treatment.
有源比较器:Conventional ventilation group
Patients in this group will receive the conventional lung-protective ventilation strategy during one-lung ventilation.

Ventilator Settings

  • Tidal Volume: 4-6 mL/kg of predicted body weight
  • Positive End-Expiratory Pressure: 5 cmH2O
  • Respiratory Rate: Adjusted to maintain an end-tidal carbon dioxide of 35-45 mmHg

大体时间
Postoperative pulmonary complication
大体时间:From enrollment to 7 days postoperatively

Composite of respiratory diagnoses that share common pathophysiological mechanisms, including pulmonary collapse and airway contamination:

  1. atelectasis detected on computed tomography or chest radiograph,
  2. pneumonia using United States Centers for Disease Control criteria,
  3. acute respiratory distress syndrome using the Berlin consensus definition, and
  4. pulmonary aspiration (clear clinical history AND radiological evidence).
From enrollment to 7 days postoperatively

大体时间
Clavien-Dindo classification
大体时间:From enrollment to 30 days postoperatively

The Clavien-Dindo classification is a standardized grading system for postoperative complications based on the therapeutic treatment required to manage the complication.

The Clavien-Dindo classification grades surgical complications according to the invasiveness and complexity of the therapy needed to treat them, ranging from any deviation from the normal postoperative course to death.

Grading Scale Overview Grade I: Any deviation from the normal postoperative course without the need for pharmacological treatment.

Grade II: Requiring pharmacological treatment with drugs other than those allowed for Grade I complications Grade III: Requiring surgical, endoscopic, or radiological intervention. Grade IV: Life-threatening complication. Grade V: Death of a patient

From enrollment to 30 days postoperatively
