Summary: | [Background] We evaluated whether coagulation/fibrinolysis markers can be a predictor for massive transfusion (MT) in patients with severe blunt trauma. [Methods] This study included blunt trauma patients based on the J–OCTET database. Patients were divided into MT (transfusion of 10 or more units of packed red blood cells in the first 24 hours after admission) and non–MT groups. We evaluated MT predictors (age, sex, vital signs, Glasgow Coma Scale, hemoglobin, platelet count, lactate, PT–INR, D–dimer, and fibrinogen levels on admission) using stepwise multiple logistic analysis. We evaluated MT prediction accuracy by receiver operating characteristic curve, and optimal cut–off value were calculated using Youden index. [Results] Heart rate (HR) (per 10 bpm), body temperature (BT), and fibrinogen (per 10 mg/dL) were independent predictors of MT [Odds ratio (OR), 1.72, p<0.001, OR, 0.70, p=0.013, and OR, 0.89, p<0.001, respectively] . The area under the curve values for MT were 0.81 in HR, 0.60 in BT, and 0.75 in fibrinogen. Optimal cut–off values for HR, BT, and fibrinogen were 96 bpm (sensitivity 73.7%, specificity 76.6%), 36.3°C (66.7%, 48.7%), and 190 mg/dL (61.4%, 80.2%), respectively. [Conclusions] Decreased levels of fibrinogen may be one of the independent predictor of MT, with higher specificity in comparison with HR, BT.
【目的】鈍的重症外傷患者において凝固・線溶系マーカーがmassive transfusion (以下MT) (24時間以内における10単位以上の赤血球輸血) の予測因子になり得るか否かを検討した. 【方法】Japanese Observational Study for Coagulation and Thrombolysis in Early Trauma (J–OCTET) データベースの鈍的外傷患者をMTとnon–MT群に分類し, 目的変数をMTの有無, 説明変数を年齢, 性別, 搬入時バイタルサイン, Glasgow Coma Scale, ヘモグロビン値, 血小板数, 乳酸値, PT–INR, D–ダイマー値, フィブリノーゲン (Fbg) 値として, ステップワイズロジステッィク回帰分析を行い, MT予測因子を抽出した. さらに, 抽出した項目について, receiver operating characteristic (ROC) 解析を行い, Youden indexにてoptimal cut–off値を算出した. 【結果】心拍数 (per 10 bpm) [Odds ratio (OR), 1.72 ; 95%信頼区間1.47–2.05] , 体温 [0.70 ; 0.53–0.94] , Fbg (per 10 mg/dL) [0.89 ; 0.84–0.94] がMTの独立予測因子であった. ROC曲線下面積は, 心拍数 : 0.81, 体温 : 0.60, Fbg : 0.75であった. Optimal cut–off値は心拍数96 bpm (感度73.7%, 特異度76.6%), 体温36.3°C (感度66.7%, 特異度48.7%), Fbg 190 mg/dL (感度61.4%, 特異度80.2%) であった. 【結語】鈍的重症外傷におけるMTの必要性に関して, Fbg値は心拍数, 体温に比較し, 特異度の高い予測因子となる可能性がある. |
