Abstract:Objective: To compare the pain-related patient-reported outcomes in lung cancer patients undergoing thoracoscopic surgery with non-intubated with spontaneous ventilation versus double-lumen endotracheal intubated anesthesia. Methods: A total of 215 lung cancer patients who underwent thoracoscopic surgery were enrolled. Of these, 110 patients received non-intubated anesthesia with spontaneous ventilation, while 105 double-lumen endobronchial intubated anesthesia. Pain during anesthesia recovery period were observed using the Critical Care Pain Observation Tool. Pain intensity and pain interference were assessed on the first postoperative day using the International Pain Outcomes Questionnaire. On the first two postoperative days, anesthesia-related symptoms such as sore throat, hoarseness, and dizziness were evaluated using a Numeric Rating Scale. Results: During the anesthesia recovery period, pain severity in both groups was mild, the incidences of sore throat and hoarseness in non-intubated group were significantly lower than in the intubated group (15.35% and 6.36%, vs 29.52% and 15.45%, P<0.05). On the first postoperative day, the incidences of severe pain, nausea and dizziness in non-intubated group were significantly lower than in intubated group (16.36%, 7.27% and 10.91%, vs 54.29%, 21.90% and 35.24%, P<0.05). Significant lower levels in the pain interference with activities in bed , deep breathing, coughing, and anxious in the non-intubated group were also observed (P<0.05). Conclusion: Patients undergoing video-assisted thoracoscopic lung cancer surgery under non-intubated anesthesia with spontaneous ventilation report better pain-related outcomes and a lower incidence of postoperative hoarseness and sore throat.
