目的研究中毒严重度评分(PSS评分)与氢氟酸灼伤患者预后的关系,为氢氟酸灼伤临床救治提供参考。方法电子检索2005年1月1日到2014年12月31日同方知网全文数据库、万方数字化期刊数据库、维普科技期刊数据库、中国生物医学文献数据库,收集氢氟酸灼伤病例,按统一标准筛选文献后进行数据提取。回顾性分析筛选后氢氟酸灼伤病例入院即刻PSS评分,观察预后情况。结果共有40篇文献(213例)收录。统计分析表明,PSS评分越高,氢氟酸灼伤患者病死率越高,预后越差(趋势χ2=26.860,P<0.01);多因素Logistic回归分析表明,PSS评分与患者预后有相关性,PSS评分>1是病例死亡的危险因素(P<0.05)。结论入院时PSS评分可考虑作为评估患者氢氟酸灼伤严重程度的指标,并可反映患者预后情况。 Objective To study the relationship between the severity of poisoning (PSS) score and the prognosis of hydrofluoric acid burn patients, and to provide a reference for the clinical treatment of hydrofluoric acid burn. Methods Electronic retrieval January 1, 2005 to December 31, 2014 Tongfangzhidu full-text database, Wanfang digital periodicals database, the VIP science and technology journals database, China Biomedical Literature Database, collected cases of hydrofluoric acid burn, according to a uniform standard screening After the literature data extraction. Retrospective analysis of hydrofluoric acid after screened cases of admission immediately PSS score, to observe the prognosis. Results A total of 40 articles (213 cases) included. Statistical analysis showed that the higher the PSS score, the higher the mortality rate of hydrofluoric acid burn patients, the worse the prognosis (trend χ2 = 26.860, P <0.01). The multivariate Logistic regression analysis showed that the PSS score correlated with the prognosis of the patients. PSS Score> 1 is a risk factor for case death (P <0.05). Conclusions The admission PSS score can be considered as an index for evaluating the severity of hydrofluoric acid burns in patients and can reflect the prognosis of patients.
