Tubeless Anesthesia in Preventing Lung Complications in Patients Undergoing Surgery for Early-Stage Lung Cancer

The study focuses on evaluating the effectiveness and safety of tubeless anesthesia in single-port thoracoscopic surgery for early-stage lung cancer patients. Traditional anesthesia methods risk postoperative complications like lung injury and respiratory issues. Tubeless anesthesia preserves spontaneous breathing without tracheal intubation, potentially reducing these complications and enhancing recovery. The study aims to compare this technique with traditional methods, assessing its impact on contralateral lung complications, perioperative hemodynamics, complication rates, and recovery speed.

Inclusion Criteria:

1. Age ≥18 years and ≤70 years;
2. ECOG performance status score 0-1;
3. Good cardiac and pulmonary function;
4. Single or multiple peripheral lung nodules planned for single-port thoracoscopic surgery, with or without mediastinal lymph node dissection or sampling;
5. Able to comply with the study visit schedule and other protocol requirements;
6. Signed informed consent and voluntary participation in the study.

Exclusion Criteria:

1. Obese patients (BMI \>30);
2. Patients with difficult intubation or expected complex airway management;
3. COPD patients with copious airway secretions;
4. Patients with neurological dysfunction or who cannot cooperate while awake;
5. Patients expected to have extensive pleural adhesions or with previous lung resection;
6. Elderly and frail patients with severe hypoxia (PaO2 \<60 mmHg) or hypercapnia (PaCO2 \>50/55 mmHg);
7. Previous induction chemotherapy or chemoradiotherapy;
8. Intraoperative need to isolate the lung to prevent spillage and contamination of the contralateral lung;
9. Patients expected to have large surgical wounds and lengthy procedures, clinically assessed as unsuitable;
10. Patients whose cardiac and pulmonary function, or overall health, cannot withstand the procedure.
