Purpose: The present study was designed to evaluate the safety and efficacy of computed tomography-guided percutaneous microwave ablation (MWA) to treat pulmonary nodules under conscious analgosedation with sufentanil. Materials and Methods: February to May 2021, 124 patients with 151 pulmonary nodules were enrolled in this study. The patients underwent 124 sessions of MWA. Sufentanil (0.25 μg/kg) was injected intravenously before MWA. Results: The technical success was 100% and no procedure-related deaths. The dosage of sufentanil was 16.6 ± 3.0 μg. The mean tumor diameter in the enrolled patients was 1.3 ± 0.8 cm. The intraoperative mean numerical rating scale (NRS) was 2.2 ± 1.7. Among the patients with NRS >3, seven patients had nodules adjacent to the pleura, while in ten patients, they were not adjacent. The mean systolic, diastolic blood pressure, and heart rate of patients were 139.1 ± 23.5 mmHg, 77.8 ± 12.3, and 76.1 ± 13.4 times/min, respectively, before sufentanil injection. The mean lowest systolic, lowest diastolic blood pressure, and lowest heart rate intraoperative were 132.9 ± 22.0 mmHg, 76.1 ± 12.1, and 74.0 ± 13.5 times/min. Twenty-six patients had mild adverse events including nausea (6.45%, 8/124), dizziness (2.42%, 3/124), vomiting(4.03%, 5/124), nausea and dizziness (2.42%, 3/124), nausea with vomiting and dizziness (2.42%, 3/124), urinary retention (1.61%, 2/124) and respiratory depression (0.81%, 1/124). Conclusion: Sufentanil is a feasible, safe, and effective analgesic for MWA in patients with pulmonary nodules. It can be used for clinical promotion.
