Anesthesia Comparison in Early-stage Small NSCLC: A Multicenter RCT

Starting soon · Not applicable

Conditions studied: Patients With Suspected Non-small Cell Lung Cancer (NSCLC) at Clinical Stage T1

In brief

This study is a prospective, randomized, controlled study, which intends to enroll patients with suspected early-stage NSCLC (non-small cell lung cancer) with a diameter of ≤ 3 cm as research subjects. The study is conducted in accordance with the Declaration of Helsinki. It has been approved by the Ethics Committee of the Second Affiliated Hospital of Air Force Medical University, and patients or their family members have signed the informed consent form. Patients undergoing VATS (video-assisted thoracic surgery) are enrolled in the Department of Thoracic Surgery of the Second Affiliated Hospital of Air Force Medical University. The patients are randomly divided into two groups: the NIVATS (non-intubated video-assisted thoracic surgery) group and the OLV (one-lung ventilation) group. By observing various perioperative indicators of the patients, the short-term efficacy of the two techniques in patients with early-stage NSCLC is compared, so as to evaluate the safety and effectiveness of the NIVATS surgical treatment method.
