Physiologic evaluation of pulmonary function in the candidate for lung resection

Area of Science:

• Thoracic Surgery
• Pulmonary Medicine
• Cardiopulmonary Physiology

Background:

• Pulmonary resection is a major surgery with significant risks.
• Accurate patient selection is crucial for optimizing outcomes and minimizing mortality.
• Preoperative assessment of pulmonary function is essential for surgical decision-making.

Purpose of the Study:

• To establish precise pulmonary function test (PFT) criteria for different types of pulmonary resections.
• To evaluate the impact of these PFT criteria on patient selection and surgical outcomes.
• To determine if a standardized PFT approach can reduce perioperative mortality.

Main Methods:

• Analysis of 2340 patients undergoing pulmonary resection from 1974-1990.
• Defined specific PFT thresholds for pneumonectomy, lobectomy, and wedge/segmental resection.
• Utilized split perfusion lung scans and Reichel exercise stress testing as adjuncts.
• Applied established PFT criteria to patient selection for various resections.

Main Results:

• Established distinct PFT criteria for pneumonectomy, lobectomy, and smaller resections.
• Implementation of these criteria led to a more precise patient selection process.
• Surgical mortality rates were reduced following the application of these PFT guidelines.
• Less than 1% of patients considered for resection were denied surgery based on these criteria.

Conclusions:

• Comprehensive pulmonary function analysis provides a precise method for selecting patients for pulmonary resection.
• Adherence to defined PFT criteria can significantly lower mortality associated with lung surgery.
• This approach optimizes surgical candidacy, ensuring appropriate patients undergo resection while minimizing unnecessary risk.
