Objective:To explore the predictive factors for extubation in the operating room after single lung transplantation without the assistance of extracorporeal membrane oxygenation (ECMO) in adult patients with end-stage interstitial lung disease (ILD), as well as their short-term (1-year postoperative) prognosis.Methods:A retrospective analysis was conducted on the clinical data of 78 adult ILD recipients who underwent single lung transplantation without ECMO assistance at the First Affiliated Hospital of Guangzhou Medical University from June 2018 to June 2023. Based on whether extubation was completed in the operating room (OR), patients were divided into the OR group (19 cases) and ICU group (59 cases). Baseline characteristics of donors and recipients, as well as intraoperative events, were compared between the two groups. Univariate logistic regression analysis was used to identify potential predictors, and variables with P<0.2 were included in multivariate logistic regression to determine independent predictors for OR extubation. Receiver operating characteristic (ROC) curves were plotted to evaluate predictive performance. The Kaplan-Meier method was used to analyze survival, and short-term prognosis between groups was compared. Results:The rate of OR extubation after single lung transplantation in ILD recipients was 24%(19/78). Compared with the ICU group, the OR group had shorter operation times, lower fluid volumes, reduced transfusions of red blood cells and plasma, less intraoperative bleeding, and lower lactate levels 15 minutes after pulmonary artery reperfusion (all P<0.05). Univariate logistic regression analysis identified the following factors as significantly associated with OR extubation: recipient age ( P=0.100), operative time ( P=0.001), fluid infusion volume ( P=0.005), red blood cell transfusion volume ( P=0.037), plasma transfusion volume ( P=0.039), blood loss ( P=0.004), oxygenation index at 15 minutes after reperfusion ( P=0.174), and blood lactate at 15 minutes after reperfusion ( P=0.041). Multivariate analysis revealed that intraoperative blood loss was an independent predictor of OR extubation ( OR=0.993, 95% CI: 0.986 - 0.999, P=0.026). ROC curve analysis showed that blood loss had an area under the curve (AUC) of 0.822 in predicting OR extubation, with a sensitivity of 64.4% and specificity of 89.5%. Postoperatively, patients in the OR group had significantly shorter durations of mechanical ventilation [0 vs 5 (3,11) days, P<0.001], ICU stay [7(4,8) vs 9(6,20) days, P=0.012], and overall postoperative hospitalization [19 (15,23) vs 25 (19,39) days, P=0.015]. Within one year after surgery, 2 patients (11%) in the OR group and 19 patients (32%) in the ICU group had died, but the difference in 1-year survival rates between the two groups was not statistically significant. Conclusions:Intraoperative blood loss is an independent predictor of extubation in the operating room. Early extubation in non-ECMO-assisted single lung transplantation for ILD patients is associated with improved short-term outcomes.

OBJECTIVESTo analyze the technical aspects of uterine artery embolization with dextran microspheres and to evaluate the effectiveness of this technique as the primary treatment of uterine fibroids in a series of 38 patients.
METHODSThirty-eight volunteers (age range, 24-48 years; mean, 37.2 years) with symptoms caused by uterine fibroids (menorrhagia, mass-related symptoms, and pelvic pain) were randomly included in this study. The fibroids were single in 32 patients and multiple in 6 patients. According to the tumor location, subserous fibroids were found in 4 patients and interstitial or submucosal fibroids in 34. Tumor size was from 2 to 10.9 cm in diameter. We performed embolization with a single Headhunter catheter using the right-femoral artery approach, injection of dextran microspheres (225-450 micro m), and an absorbable gelatin sponge. Follow-up included clinical and sonographic examinations at one-month intervals for 6 months.
RESULTSEmbolization was successfully performed in all patients. Post-procedural pain control was good in 35 (92%) patients. In most patients, symptoms were improved at 3 months (36/38, 95%). Clinical failure of the treatment occurred in only 2 patients (2/38, 5%). Progressive reduction in leiomyoma size was revealed during sonographic follow-up, and the reduction rate at the sixth month after embolization was 68%. The tumor had vanished in five submucosal fibroid patients. Histopathological tests showed that the tumor was degenerative as fibrosis and hyalinosis.
CONCLUSIONSUterine artery embolization with dextran microspheres is a micro-invasive method for the treatment of uterine fibroids. It is clinically effective in most patients and induces a progressive reduction in the size of fibroids. Based on this study, we believe that this new technique is much more suitable for submucosal fibroids with massive menorrhagia.
