A retrospective review of 81 emergency department patients was performed to determine the accuracy of blood ethanol levels (BEL) calculated from serum osmolality. The osmolar gap (measured-calculated serum osmolality) was used to determine the calculated BEL. The mean difference between calculated and measured BEL was 49.2 mg/dL. Calculated BEL overestimated measured BEL in 83% of patients. Adding a correction factor for unmeasured osmoles to the equation for calculated serum osmolality will reduce this error.
对81名急诊科患者进行了回顾性研究，以确定根据血清渗透压计算的血液乙醇水平（BEL）的准确性。渗透压间隙（测量值-计算出的血清渗透压）用于确定计算出的BEL。计算出的BEL与测量出的BEL之间的平均差异为49.2mg/dL。在83%的患者中，计算出的BEL高估了测量出的BEL。在计算血清渗透压的公式中加入未测量渗透压的校正因子将减少这一误差。
