About this study
Official title: A Multicenter, Randomized, Controlled Trial of Non-Intubated Spontaneous Breathing Anesthesia Versus Intubated Mechanical Ventilation Anesthesia in Thoracoscopic Sublobar Resection: A Stratified Analysis Study Focusing on Safety and Recovery Quality
This is a large clinical study that compares two different types of anesthesia for patients undergoing a specific kind of minimally invasive lung surgery (thoracoscopic sublobar resection) to remove small, early-stage lung nodules.
The study aims to find out if a newer anesthesia method, known as "non-intubated anesthesia" (where patients breathe on their own with the help of a laryngeal mask airway and nerve blocks for pain control), is as safe as the traditional "intubated anesthesia" (which uses a breathing tube and a machine to breathe for the patient).
Read more
The main goals of the study are, in order:
- Safety First: To confirm that the non-intubated method does not lead to more lung complications within 30 days after surgery compared to the traditional method.
- Effectiveness: If it is proven safe, the study will then check if patients receiving the non-intubated anesthesia have a better quality of recovery in the first 24 hours after surgery (e.g., less pain, fewer side effects like a sore throat, and a faster return to normal activities).
Approximately 1600 patients from multiple hospitals will be randomly assigned (like flipping a coin) to receive one of the two anesthesia methods. Neither the patients nor the surgeons will be told which group the patient is in when assessing the main outcomes after surgery, to ensure the results are fair and unbiased.
The results of this study will provide high-quality evidence to help doctors and patients choose the best and most comfortable anesthesia option for this type of lung surgery.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Non-intubated AnesthesiaProcedure or surgery
A novel anesthetic technique for thoracic surgery that avoids endotracheal intubation and mechanical ventilation. It typically involves intravenous sedation, the use of a laryngeal mask airway (LMA) for oxygenation, and regional nerve blocks (e.g., paravertebral block) for pain control. The key feature is the preservation of the patient's spontaneous breathing throughout the surgical procedure.
Conventional Intubated General AnesthesiaProcedure or surgery
The current standard anesthetic technique for thoracoscopic surgery. It involves general anesthesia induced by intravenous agents, followed by the insertion of a double-lumen endotracheal tube to achieve one-lung ventilation. Anesthesia is maintained with inhalational or intravenous agents, and the patient's ventilation is fully controlled by a mechanical ventilator throughout the operation.
Laryngeal Mask Airway (LMA)Device
Airway management using a laryngeal mask airway to maintain spontaneous ventilation during thoracoscopic surgery.
Intravenous Sedation/Anesthesia (Spontaneous Ventilation)Drug
Intravenous sedative/anesthetic agents administered to achieve adequate anesthesia while preserving spontaneous breathing.
Regional Nerve Block (Paravertebral/Intercostal Block)Drug
Regional anesthesia with local anesthetic (e.g., paravertebral or intercostal block) for perioperative analgesia.
Double-lumen Endotracheal Tube (DLT)Device
Double-lumen endotracheal tube used to achieve one-lung ventilation during general anesthesia.
General Anesthesia With Neuromuscular BlockadeDrug
General anesthesia maintained with intravenous and/or inhalational agents with muscle relaxation for controlled mechanical ventilation.
| Study group | Role | What they receive |
|---|---|---|
| Non-intubated Anesthesia Group | Experimental | Patients randomized to this group will receive the experimental intervention, non-intubated spontaneous breathing anesthesia. The key components include:
Airway Management: A laryngeal mask airway will be used instead of an endotracheal tube.
Anesthesia Technique: Intravenous sedation will be administered to maintain spontaneous breathing, combined with regional nerve blocks (e.g., paravertebral or intercostal block) for analgesia.
Goal: This approach aims to avoid the potential trauma and lung injury associated with double-lumen tube intubation and mechanical ventilation.
A predefined set of safety criteria for conversion to intubated anesthesia (e.g., low oxygen levels, excessive carbon dioxide buildup) will be strictly followed during the procedure. Receives: Procedure: Non-intubated Anesthesia; Device: Laryngeal Mask Airway (LMA); Drug: Intravenous Sedation/Anesthesia (Spontaneous Ventilation); Drug: Regional Nerve Block (Paravertebral/Intercostal Block) |
| Conventional Anesthesia Group | Active comparator | Patients randomized to this group will receive the current standard of care for thoracoscopic lung surgery, which is conventional intubated general anesthesia. The intervention consists of:
Airway Management: Double-lumen endobronchial tube intubation to achieve one-lung ventilation.
Anesthesia Technique: Standard general anesthesia with muscle relaxation and controlled mechanical ventilation.
This approach represents the well-established, traditional method against which the experimental non-intubated anesthesia is being compared. Receives: Procedure: Conventional Intubated General Anesthesia; Device: Double-lumen Endotracheal Tube (DLT); Drug: General Anesthesia With Neuromuscular Blockade |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of composite perioperative complications
This primary outcome measures the incidence of a composite of postoperative pulmonary complications (PPCs) within 30 days after surgery. The composite endpoint includes the occurrence of any one of the following predefined complications: pneumonia, respiratory failure, atelectasis requiring bronchoscopy, acute lung injury (ALI)/acute respiratory distress syndrome (ARDS), pulmonary embolism, bronchopleural fistula, pleural effusion requiring drainage, or pneumothorax requiring intervention. The assessment period begins at anesthesia induction and concludes 30 days post-surgery.
Measured: From anesthesia induction up to 30 days after surgery
Postoperative recovery quality assessed by the QoR-15 score
This primary outcome measures the quality of patient recovery at 24 hours after surgery using the validated Quality of Recovery-15 (QoR-15) questionnaire. The QoR-15 score encompasses 15 items across five dimensions: physical comfort (5 items), emotional state (4 items), physical independence (2 items), psychological support (2 items), and pain (2 items). Each item is scored on a scale from 0 to 10. The total score ranges from 0 (extremely poor quality of recovery) to 150 (excellent quality of recovery). A higher total score indicates a better postoperative recovery experience from the patient's perspective.
Measured: At 24 hours after surgery
Secondary outcomes (2)
Length of postoperative hospital stay
The duration of hospitalization in days, calculated from the day of surgery to the day of meeting discharge criteria (e.g., adequate pain control with oral analgesics, no air leak, afebrile, able to ambulate independently).
Measured: From the day of surgery until the day of discharge, assessed up to 30 days.
Incidence of intraoperative conversion
The rate of conversion from non-intubated anesthesia to conventional intubated general anesthesia due to unacceptable surgical conditions (e.g., poor lung collapse, diaphragmatic movement) or patient safety concerns (e.g., hypoxemia, hypercapnia, hemodynamic instability).
Measured: During the surgical procedure (from anesthesia induction until skin closure).

Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
