Objective:To improve the understanding of acute pain after thoracoscopic surgery in patients with early-stage lung adenocarcinoma, to analyze and screen out the independent risk factors that may induce acute postoperative pain. The patients' surgery experience may get improved through the corresponding timely and effective interventions.Methods:We retrospectively reviewed the clinical data of 204 patients with early-stage lung adenocarcinoma who were treated by a single medical team of our center from May 2021 to October 2021, and analyzed the assessment results of acute postoperative pain. Patients were grouped according to the general condition, past medical history, social and spiritual attributes, lesion characteristics, surgical approaches and anesthetic methods. Comparison of proportions of acute postoperative pain between the groups were made, and independent risk factors were identified.Results:A total of 84 males and 120 females were enrolled, with a mean age of(57.9±11.5)years old and a median operation time of 120(110, 145) min. No serious complication or perioperative death occurred in the whole group. Postoperative pain control failed in 76 cases(37.3%), 24 cases(11.8%) suffered from severe postoperative pain, and 33 cases(16.2%) required additional intramuscular injection of strong analgesics after surgery. Those who were younger than 60 years old, with a university degree or above, received two-incision surgery, operated for more than 2 h, received general anesthesia only, or in a state of depression, had significantly higher rates of postoperative acute pain, compared with their respective control groups( P<0.05). The independent risk factors for acute pain after thoracoscopic surgery included age( P=0.002), history of alcoholism( P=0.014), number of incisions( P=0.016), operation time( P=0.010), depression status( P=0.037) and enhanced anesthetic method( P=0.012). Conclusion:A large amount of patients with early-stage lung cancer suffered from acute pain after thoracoscopic surgery, which seriously affected their treatment experience and even quality of life. Young patients with a history of alcoholism and depression status were high-risk groups for postoperative acute pain. Applying Uniportal video-assisted thoracoscopic surgery, reducing the operation time as much as possible, and choosing enhanced analgesic anesthesia represented by epidural block combined with general anesthesia might be effective ways to reduce the probability of acute postoperative pain.

Objective:To assess the potentials for lung donation among 128 donors (deceased citizens) in 2017 from Beijing.Methods:Gender, age, blood type, duration of ventilation, oxygenation index (PaO 2/FiO 2), chest film and bronchoscopy were analyzed. Results:A total of 5135 deceased Chinese citizens were available for donation in 2017. The rate of donation per million population (PMP) was 3.71. And 463 donors from Beijing were recorded in 2017 and the rate of PMP was 21.05. In 2017, 299 lung transplantations were performed with an average rate of donor lung utility at 5.82%. Among 128 cases assessed for potential lung donors in Beijing, 72 were successfully procured with a percentage of lung utilization of 15.55%. There were 110 males (85.94%) and 18 females (14.06%) with an average age of (39.61±10.67) years. Mechanical ventilation duration was (7.59±2.93) days. The oxygenation rate (PaO 2/FiO 2) was (397.38±105.01) mmHg, (450±67.79) mmHg in procurement group and (338.89±116.15) mmHg in non-procurement group ( P=0.020). The median level of procalcitonin (PCT) was 0.195 ng/ml in procurement group versus 0.349 ng/ml in giving-up group ( P=0.042). Conclusions:Oxygenation rate and PCT level are the independent risk factors for reaching a procurement decision of donor lung. The actual PMP and lung procurement rate in Beijing were both higher than average domestic level (15.55% vs. 5.82%, P=0.000) because of excellent cooperation between Organ Procurement Organization (OPO) and lung transplantation centers. The evaluation of donor lungs and lung maintenance protocols from Beijing should be popularized nationwide.
