Abstract:

Objective To explore the application effect of inhaled nitric oxide(NO)in the treatment ofsevere primary graft dysfunction(PGD)after lung transplantation. Methods Clinical data of 73 lung transplant recipients with severe PGD from January 2022 to June 2025 in Wuxi People’s Hospital Affiliated to Nanjing Medical University were retrospectively analyzed. Patients were divided into NO group(n = 27)and control group(n =46). Clinical baseline characteristics,intraoperative data,and postoperative outcomes were compared. Linear regression was used to analyze influencing factors of recovery time,and Cox regression was used for 28 d mortalityrisk factors. Results The ECMO duration in the NO group was significantly shorter than that in the control group (P = 0.017). Linear regression showed that NO was a favorable factor for shortening ECMO duration(β = -0.402,P =0.023),invasive ventilation time(β= -0.361,P = 0.036),and ICU stay time(β= -0.325,P = 0.024). Multivariate Cox regression showed donor age was an independent risk factor for 28 d mortality(P < 0.05). The 28-day survival rate was significantly higher in the NO group(85.2% vs. 63.0%,P = 0.044). Conclusion This study found that the NOgroup had shorter ECMO duration and higher 28 d survival rate,though further validation is required.

摘要:

目的 探讨一氧化氮(nitric oxide,NO)吸入在肺移植术后重度原发性移植物失功(primary graft dysfunction,PGD)治疗中的应用效果。 方法 回顾性分析 2022 年 1 月至 2025 年 6 月南京医科大学 附属无锡人民医院收治的 73 例重度 PGD 受者资料。根据是否吸入 NO 分为治疗组(27 例)和对照组(46 例)。比较两组受者及供者的临床基线资料、术中情况及术后康复指标 。采用线性回归分析 ECMO 应用时间的影响因素,利用Cox回归分析术后28 d死亡风险。 结果 治疗组ECMO辅助时间明显短于对照组(P=0.017)。线性回归显示,吸入 NO 是缩短重度 PGD 受者 ECMO 应用时间(β = -0.402,P = 0.023)、有创通气时间(β = -0.361,P = 0.036)及 ICU 住院时间(β = -0.325,P = 0.024)的有利因素。多因素 Cox 回归分析提示,供体年龄是受者术后 28 d 死亡的独立危险因素(P < 0.05)。治疗组术后 28 d 生存率为 85.2%,显著 高于对照组的 63%(P = 0.044)。 结论 本研究发现 NO 治疗组 ECMO 应用时间更短、28 d 生存率更高,但需进一步研究证实。
