观察改良早期预警评分（MEWS）用于腹部闭合性创伤评估的临床效果。

收集2008年1月至2017年11月芜湖市第五人民医院收治的160例腹部闭合性创伤患者资料，回顾性分析并统计所有患者临床诊治及预后资料，采用MEWS评分系统进行评估，观察患者分诊情况（门诊或专科保守治疗、ICU抢救、中转手术）、治疗过程中并发症发生情况及30 d内预后状况。

160例患者中保守治疗64例（40.0%），入住ICU抢救96例（60.0%）；中转手术34例（21.3%）。MEWS评分>8分者16例，均分诊为入住ICU抢救，保守治疗率明显低于其他各分值段（MEWS评分>6~8分除外），入住ICU抢救率明显高于其他各分值段（MEWS评分>6~8分除外），中转手术率明显低于MEWS评分<3分及3~4分值段，上述差异均有统计学意义（P<0.05）。160例患者30 d内预后良好124例（77.5％），MEWS评分为（2.44±1.32）分；预后不良36例（22.5%），MEWS评分为（6.84±2.12）分，其中死亡12例（7.5％），感染16例（10.0％），多器官衰竭4例（2.5％），应激溃疡4例（2.5％）。ROC曲线分析显示MEWS评分对腹部闭合性创伤患者预后不良有一定预测价值，曲线下面积为0.919（P<0.001，95% CI=0.797~1.000），预测预后不良最佳截断值为5.970分，敏感度0.667，特异度0.986。

采用MEWS预警评分对评估腹部闭合性创伤患者就诊时分诊及预后具有重要作用，减少并发症及死亡率，改善预后。

To observe the clinical effect of modified early warning score (MEWS) in evaluating closed abdominal trauma.

From January 2008 to November 2017, one hundred and sixty patients with closed abdominal trauma admitted to the Fifth People’s Hospital of Wuhu were enrolled. Clinical diagnosis and prognosis data were retrospectively analyzed. The MEWS system was used to evaluate the patients’ diagnosis (outpatient or specialist conservative treatment, ICU rescue, transfer operation), complications in the course of treatment and 30 days’ prognosis.

Among the 160 patients, 64 cases (40.0%) were treated conservatively, 96 (60.0%) were admitted to ICU, and 34 (21.3%) underwent transfer operation. There were 16 cases with MEWS score >8. The rate of conservative treatment was significantly lower than that of other scores (except of MEWS score >6-8). The rate of rescue in ICU (100.0%) was significantly higher than that in other segments (except of MEWS score >6-8). The conversion rate was significantly lower than the MEWS score <3 and 3-4 segments. The prognosis in 30 d was good in 124 cases (77.5%), the MEWS score was (2.44±1.32), 36 (22.5%) with poor prognosis, and the MEWS score was 6.84±2.12. Twelve cases (7.5%) died, 16 (10.0%) were infected, 4 (2.5%) had multiple organ failure, and 4 cases (2.5%) suffered from stress ulcer. The ROC curve analysis showed that the MEWS score had a certain predictive value for poor prognosis in patients with closed abdominal trauma. Area under the curve was 0.919 (P<0.001, 95% CI=0.797-1.000), the cut-off value was 5.970, the sensitivity was 0.667, and the specificity was 0.986.

MEWS plays an important role in choosing triage protocols and evaluating prognosis of closed abdominal trauma, reducing complications and mortality, and improving the prognosis.
