A review of 737 limited toxicological screens performed in a municipal teaching hospital over one calendar year was conducted to determine the value of performing analyses for ethanol, salicylates, and barbiturates. Less than 5% of salicylate determinations and less than 2% of barbiturate tests yielded positive results. On the other hand, ethanol was present in over 70% of cases. The low number of positive results and the cost do not justify analyzing for salicylates or barbiturates unless their presence is suspected. Ethanol determinations should be limited to patients without an obviously consistent clinical presentation. Selective use of these tests in the emergency department is called for.
对一家市级教学医院在一个日历年内进行的737次有限毒理学筛查进行了回顾，以确定对乙醇、水杨酸盐和巴比妥类药物进行分析的价值。水杨酸盐测定结果呈阳性的比例不到5%，巴比妥类药物检测结果呈阳性的比例不到2%。另一方面，超过70%的病例中存在乙醇。阳性结果数量少且成本高，因此除非怀疑存在水杨酸盐或巴比妥类药物，否则对其进行分析并不合理。乙醇测定应仅限于临床表现无明显一致性的患者。急诊科需要选择性地使用这些检测。
