【摘要】 目的　评估红细胞压积 (HCT)对重症胰腺炎早期识别的临床价值。方法　收集深圳市南山医院消化科 1997年 1月～ 2 0 0 1年 12月急性胰腺炎首次发作的住院病人共 2 0 9例 ,选取病人住院 2 4小时内的HCT值 (男性HCT >43 0 % ;女性HCT >3 9 6% )作为重症胰腺炎识别的指标。结果　 2 0 9例急性胰腺炎 ,重症 3 9例 (18 66% ) ,HCT判别重症胰腺炎的敏感性、特异性分别为 43 5 9%和 71 76% ,阳性预测值、阴性预测值分别为 2 6 15 %和 84 0 6%。结论　易得、廉价的HCT作为重症胰腺炎早期识别的指标的主要临床意义在于其阴性预测值较高 ,提示HCT不高者发生重症的可能性较小 ,除非病情加剧 ,暂可不必行胰腺CT检查更多还原

【Abstract】 Objective To evaluate hematocrit (HCT) as an early marker of severe pancreatitis.Methods The study covered the years 1997～2001 for 209 inpatients with a first attack of acute pancreatitis in Nanshan hospital.Criteria for severe pancreatitis was Alalantic Criteria 1992.The HCT>43 0% for male and >39.6% for female,within 24 h after admission,was defied as an early marker of severe pancreatitis.Results Of 209 patients,39 were severe pancreatitis.The sensitivity and specificity of the HCT to detect severe pancreatitis were 43.59% and 71.76%, respectively.The positive predictive value was 26.15% and negative predictive value was 84.06%.Conclusion The major value of this single easily obtainable and cheap parameter on admission lies in its high negative predictive value.In the absence of hematocrit,conrast enhance CT may be unnecessary on admission unless the patient does not improve.更多还原
