Clinical application of mobile CT combined with procedural sedation and analgesia in the preoperative localization of multiple pulmonary nodules

Objective To evaluate the safety and efficacy of mobile CT combined with procedural sedation and analgesia for the preoperative localization of multiple nodules. Methods The clinical data of 200 patients who underwent CT-guided localization before single-port thoracoscopic pulmonary lobe surgery at our hospital from July 2023 to September 2023 were retrospectively analyzed. The patients were divided into two groups according to the localization method: Group A consisted of 100 patients who were localized under local anesthesia, and Group B consisted of 100 patients who were localized under procedural sedation and analgesia combined with local anesthesia. The general clinical data and localization data of the two groups were compared and analyzed. Results The incidence of localization complications in Group B was significantly lower than that in Group A (4% vs. 13%, P = 0.04). The localization success rate in Group B was significantly greater than that in Group A (98% vs. 92%, P = 0.04). The localization time in Group B was significantly shorter than that in Group A (15.23 +/- 5.96 min vs. 19.90 +/- 8.66 min, P<0.01), and the pain score in Group B was significantly lower than that in Group A (2.01 +/- 2.09 min vs. 3.29 +/- 2.54 min, P<0.01). Conclusion Mobile CT combined with procedural sedation and analgesia for preoperative puncture localization of multiple pulmonary nodules is safe and effective, with significant clinical application value.
