Mortality from trauma remains a major public health issue as it is the leading cause of death in persons aged 5 to 44 years. Uncontrolled hemorrhage and coagulopathy is responsible for over 50% of all trauma related deaths within the first 48 hrs of admission. Coagulation profiles are not routinely done among trauma patients in resource limited settings and there is a paucity of data on acute traumatic coagulopathy (ATC) in sub Saharan Africa. The study was conducted to evaluate the prothrombin time and partial thromboplastin time (PT/PTT) as predictors of mortality and morbidity among major trauma patients.
A prospective cohort study was carried out, in which major trauma patients admitted in A&E department between December 2011 to April 2012 were recruited. Five (5) mls of venous blood was drawn from a convenient vein within 10 minutes of the patient's arrival at A&E for analysis of PT/PTT. Patients were stratified into two groups by the presence/absence of coagulopathy then followed up for a 2 week period for morbidity and mortality.
A total of 182 major trauma patients were recruited; 149 (81.9%) were males, the mean age was 29.5 years (SD 9.8). Prevalence of coagulopathy was 54% (98/182). The mean ISS for the ATC group was 36.9 and the non ATC group was 26.9 (p=0.001). Patients with ATC stayed longer in hospital 11.24 days than non ATC patients 8 days (p=0.001). ATC was strongly associated with ARI (p= 0.003). Mortality was more in the ATC group 29 deaths compared to 9 deaths in the non ATC group. PTT was a strong independent predictor of mortality.
A significant proportion of major trauma patients were coagulopathic. Initial coagulation profile is useful in predicting outcomes for major trauma patients.
创伤导致的死亡率仍然是一个主要的公共卫生问题,因为它是 5 至 44 岁人群死亡的主要原因。在入院后的前 48 小时内,超过 50%的与创伤相关的死亡是由无法控制的出血和凝血障碍引起的。在资源有限的环境中,创伤患者通常不会进行凝血概况检查,而且关于撒哈拉以南非洲地区急性创伤性凝血病(ATC)的数据也很少。这项研究旨在评估凝血酶原时间和部分凝血活酶时间(PT/PTT)作为预测主要创伤患者死亡率和发病率的指标。
进行了一项前瞻性队列研究,其中招募了 2011 年 12 月至 2012 年 4 月期间在急诊部门就诊的主要创伤患者。在患者到达急诊室后的 10 分钟内从方便的静脉中抽取 5 毫升静脉血,用于分析 PT/PTT。根据是否存在凝血障碍将患者分为两组,然后对两组患者进行为期 2 周的发病率和死亡率随访。
共招募了 182 名主要创伤患者;149 名(81.9%)为男性,平均年龄为 29.5 岁(标准差 9.8)。凝血障碍的患病率为 54%(98/182)。ATC 组的平均 ISS 为 36.9,非 ATC 组为 26.9(p=0.001)。ATC 患者的住院时间比非 ATC 患者长 11.24 天,为 8 天(p=0.001)。ATC 与急性呼吸窘迫综合征(ARI)密切相关(p=0.003)。ATC 组的死亡率为 29 例死亡,而非 ATC 组为 9 例死亡。PTT 是死亡率的一个强有力的独立预测因子。
相当一部分主要创伤患者存在凝血障碍。初步凝血概况对预测主要创伤患者的结局有用。
