Minimizing postoperative pulmonary complications in thoracic surgery patients

Area of Science:

• Anesthesiology
• Thoracic Surgery
• Perioperative Medicine

Background:

• Increasing multimorbidity in thoracic surgery patients elevates the risk of postoperative pulmonary complications (PPCs), which significantly impact outcomes and are a leading cause of early mortality.
• While patient-specific risk factors are often unmodifiable, procedural factors, including surgical approach and anesthetic management, are key targets for PPC reduction.

Purpose of the Study:

• To quantify and optimize perioperative risk factors, specifically focusing on anesthesia-related strategies to decrease PPCs after lung and esophageal surgery.
• To review current anesthesiological approaches for mitigating PPCs in the context of thoracic procedures.

Main Methods:

• Review of current research on perioperative risk factors and anesthetic strategies for thoracic surgery.
• Analysis of minimally invasive surgical approaches (video-assisted thoracoscopy, laparoscopy) and their impact on PPC rates.
• Evaluation of anesthesiological techniques including neuroaxial anesthesia, lung-protective ventilation, and goal-directed hemodynamic therapy.

Main Results:

• Minimally invasive surgery is associated with a reduced incidence of PPCs.
• Key anesthesiological strategies for reducing PPCs include epidural anesthesia, lung-protective ventilation (PEEP 5-8 mbar, tidal volume 5 ml/kg BW), and goal-directed hemodynamic therapy (CI ≥ 2.5 L/min/m², MAP ≥ 70 mmHg, SVV < 10%).
• Strict perioperative fluid management (≤ 6 ml/kg/hr crystalloids) is crucial.

Conclusions:

• Epidural anesthesia, lung-protective ventilation, and goal-directed hemodynamic therapy are the primary anesthesiological strategies to reduce PPCs in thoracic surgery.
• Optimizing ventilation parameters (PEEP, tidal volume) and hemodynamic targets (CI, MAP, SVV) alongside judicious fluid administration is essential for improving patient outcomes.
• These evidence-based anesthetic techniques offer a pathway to mitigate the significant morbidity and mortality associated with PPCs after lung and esophageal surgery.
