Clinical Scorecard: Evaluation of Postoperative Respiratory Complications and Intraoperative Safety in Non-Intubated versus Intubated Anesthesia for Thoracoscopic Surgery: A Randomized, Controlled, Double-Blind Non-Inferiority Study

At a Glance

Key Highlights

• IVATS with double-lumen tube intubation is associated with intraoperative circulatory fluctuations, postoperative sore throat, prolonged muscle recovery, and increased PPCs.
• NIVATS maintains spontaneous breathing, avoids intubation and mechanical ventilation, potentially reducing PPCs and intraoperative complications.
• This randomized, double-blind, non-inferiority trial enrolled 120 patients to compare incidence of PPCs between NIVATS and IVATS in selected low-risk patients.

Guideline-Based Recommendations

Diagnosis

• Assess patient eligibility based on ASA grade I–II, BMI < 25 kg/m2, Mallampati grade I–II, and absence of severe cardiovascular or respiratory disease.
• Exclude patients with difficult airway, large or complex tumors, or requiring anticoagulation therapy within one week preoperatively.

Management

• Consider NIVATS as an alternative to IVATS to avoid complications related to double-lumen tube intubation and mechanical ventilation in suitable patients.
• Perform single-port VATS with either lung cancer radical resection or lung wedge resection under anesthesia by experienced thoracic anesthesiologists.
• Use local and/or regional block anesthesia techniques to maintain spontaneous breathing during NIVATS.

Monitoring & Follow-up

• Monitor intraoperative respiratory, hemodynamic, and neurological parameters closely due to potential hypoxemia, hypercapnia, or acidosis during NIVATS.
• Observe for postoperative pulmonary complications including atelectasis, hypoxemia, and ventilator-associated lung injury in both groups.

Risks

• IVATS risks include mechanical ventilation-associated lung injury, ventilator-associated pneumonia, re-expansion lung injury, and postoperative sore throat.
• NIVATS risks include complications from regional/local anesthesia, potential ventilation compromise due to open pneumothorax, and respiratory or neurological events.

Patient & Prescribing Data

Patients with ASA I–II, BMI < 25 kg/m2 undergoing thoracoscopic surgery

NIVATS is a feasible and safe alternative to IVATS with non-inferior incidence of PPCs, potentially reducing postoperative complications and hospital stay.

Clinical Best Practices

• Careful patient selection is critical to optimize safety and outcomes in NIVATS.
• Ensure experienced anesthesiologists perform anesthesia management to handle potential intraoperative respiratory and hemodynamic challenges.
• Maintain double-blind study design and rigorous randomization to minimize bias in clinical trials comparing anesthesia techniques.
