Objective:To construct a risk prediction model for early post-injury respiratory failure in patients with traumatic cervical spinal cord injury (TCSCI) and validate its efficacy.Methods:A retrospective cohort study was conducted to analyze the clinical data of 393 TCSCI patients admitted to Zhengzhou Central Hospital Affiliated to Zhengzhou University from January 2020 to October 2024, including 294 males and 99 females, aged 18-82 years [59(45, 72)years]. Among them, 76 patients had respiratory failure (19.3%). The patients were randomly divided into the training set ( n=275) and validation set ( n=118) at a ratio of 7∶3. According to the presence of respiratory failure within one week after admission, 275 patients in the training set were divided into respiratory failure group ( n=53) and non-respiratory failure group ( n=222). The demographic data, injury characteristics, laboratory test results, and imaging findings of the patients were collected. Risk factors were determined through univariate analysis and multivariate Logistic regression analysis and a nomogram prediction model was constructed. The area under the receiver operating characteristic (ROC) curve (AUC) and Hosmer-Lemeshow test were used to evaluate the discrimination and calibration of the model. Decision curve analysis (DCA) was plotted to evaluate the clinical effectiveness of the prediction model. Results:The results of the univariate analysis showed that there were significant differences in history of respiratory diseases, causes of injury, Glasgow coma scale (GCS), American Spinal Injury Association (ASIA) classification, ASIA-motor score (AMS), injury severity score (ISS), clinical pulmonary infection score (CPIS), hypoproteinemia and cervical vertebra fracture and dislocation between the respiratory failure group and non-respiratory failure group in the training set ( P<0.05). The results of multivariate Logistic regression analysis indicated that GCS, ASIA classification, CPIS, and hypoproteinemia were independent risk factors for early post-injury respiratory failure in TCSCI patients ( P<0.05). Based on the above four variables, a Logistic regression equation was constructed: Logit( P)=2.361-0.675×ASIA classification+0.419×CPIS-0.358×GCS+0.854×hypoproteinemia. In the prediction model established based on this equation, the AUC was 0.96 (95% CI 0.94, 0.99) in the training set and 0.89 (95% CI 0.82, 0.96) in the validation set. In the calibration curves of the training set and validation set, the prediction curve and reference curve were approximately overlapping, with the average absolute errors of 0.04 and 0.03. DCA results demonstrated that both the training and validation sets exhibited positive net benefits when threshold probabilities fell within ranges of 0%-78% and 0%-87%, respectively. Conclusion:The risk prediction model for early post-injury respiratory failure in TCSCI patients based on GCS, ASIA classification, CPIS and hypoproteinemia has good predictive efficacy and clinical practicability.

Objective:To explore the risk factors of acute respiratory distress syndrome (ARDS) secondary to severe multiple trauma and the role of clinical guidance.Methods:The clinical data of 115 patients with severe multiple trauma admitted to the trauma center of Zhenjiang First People's Hospital from December 2017 to September 2020 were retrospectively analyzed. According to whether ARDS occurred within 1 week of the disease course, the patients were divided into ARDS group and non-ARDS group. The basic post-traumatic data, initial treatment measures (within 24 hours), pathophysiology, stress metabolism, and post-traumatic complications of the two groups of patients were selected for univariate analysis, the statistically different indicators of univariate analysis were incorporated into the multivariate Logistic regression analysis to screen out independent high-risk factors that affect the occurrence of ARDS in patients with severe multiple trauma, and a receiver operating characteristic curve (ROC curve) was drawn to analyze the effects of each risk factor on the occurrence of ARDS.Results:Among 115 patients, there were 45 casesin the ARDS group and 70 cases in the non-ARDS group. Compared with the non-ARDS group, the patients in the ARDS group were older (years: 57.45±15.37 vs. 45.68±12.70), and the proportion of patients combined with moderate-severe chest trauma, traumatic brain injury (TBI), shock, and massive blood transfusion were higher (71.11% vs. 31.43%, 44.44% vs. 28.57%, 80.00% vs. 67.14%, 46.67% vs. 27.14%). In the ARDS group, procalcitonin [PCT (μg/L):29.73±6.08 vs. 12.45±2.12], thrombomodulin [TM (ng/L): 83.43±16.34 vs. 37.66±14.64], blood glucose (mmol/L:17.2±5.0 vs. 10.3±2.4), triacylglycerol [TG (mmol/L): 3.77±0.57 vs. 2.22±0.63], interleukin-6 [IL-6 (ng/L):38.97±10.79 vs. 25.98±5.40], tumor necrosis factor-α [TNF-α (ng/L): 48.78±13.99 vs. 35.30±13.03], intra-abdominal pressure [mmHg (1 mmHg = 0.133 kPa): 25.21±3.59 vs. 11.98±4.91], serum creatinine [SCr (μmol/L):180.45±42.35 vs. 132.17±49.36] and blood urea nitrogen [BUN (mmol/L): 13.83±4.97 vs. 8.80±4.32] were significantly higher than those in the non-ARDS group; the proportion of patients with crystal infusion volume ≥ 3 000 mL(26.67% vs. 34.29%) and platelet count [PLT (×10 9/L): 72.67±7.96 vs. 127.99±17.65] and the levels of plasma glutathione peroxidase [GSH-Px (kU/L): 87.15±27.81 vs. 161.15±17.94], plasma superoxide dismutase [SOD (kU/L):92.65±32.67 vs. 125.58±38.96] were significantly lower than those in the non-ARDS group, the differences were statistically significant (all P < 0.05). Multivariate Logistic regression analysis showed that 11 indicators such as age, combined moderate-severe chest trauma, combined TBI, massive blood transfusion, PCT, TM, blood glucose, TNF-α, plasma GSH-Px, intra-abdominal pressure and SCr were independent risk factors that could predict ARDS secondary to severe multiple trauma, the odds ratio ( OR) and 95% confidence interval (95% CI) were 1.201 (1.035-1.165), 3.414 (1.217-8.876), 2.889 (1.124-8.109), 3.134 (1.322-9.261), 1.467 (1.096-2.307), 2.428 (0.024-0.973), 5.787 (1.246-9.642), 1.106 (0.949-5.108), 7.450 (1.587-10.261), 3.144 (1.217-8.876), 1.051 (1.002-1.542) respectively, the P valueswere 0.008, 0.024, 0.044, 0.017, 0.018, 0.045, 0.026, 0.037, 0.005, 0.029, 0.033 respectively. ROC curve analysis showed that plasma GSH-Px had a higher predictive value for ARDS secondary to severe multiple trauma, the area underROC curve (AUC) = 0.873, 95% CI was 0.798-0.928, P = 0.000, when the best cut-off value at 72.22 kU/L, its sensitivitywas 86.7%, specificity was 75.7%, positive predictive value was 69.6%, and negative predictive value was 89.8%. The Logistic regression model established by 11 independent high-risk factors had an accuracy rate of 81.74% in predicting ARDS secondary to severe multiple trauma, which had a good guiding significance for predicting ARDS. Conclusion:Our study showed that there are many risk factors for ARDS secondary to severe multiple trauma, involvingbasic post-traumatic data, initial treatment measures, pathophysiology, stress metabolism, post-traumatic complications, etc. Early identification and intervention may be beneficial to improve the success rate of treatment for such patients.
