With the purpose to compare the observed and expected mortality rates (based on the PRISM score) in the Pediatric Intensive Care Unit (PICU) of the "Hospital para el Niño Poblano", a prospective study of 92 patients admitted from August to December of 1992 was made. More than five percent of mortality risk was observed among 60.2% of the patients at the PICU admittance. The predicted mortality was not different from the expected mortality (P < 0.05). We observed that seven of ten patients who died with less than 50% mortality risk, had inotropic treatment previously to PICU admittance, there was no haemodynamic alterations in these patients at the PICU admittance, and the PRISM score was low. We suggest that the PRISM score should be interpreted with caution in those patients whose treatment may change the physiologic variables included in the PRISM score.
为比较“墨西哥普埃布拉诺儿童医院”儿科重症监护病房（PICU）的观察死亡率和预期死亡率（基于PRISM评分），我们对1992年8月至12月收治的92例患者进行了一项前瞻性研究。在PICU入院时，60.2%的患者观察到死亡风险超过5%。预测死亡率与预期死亡率无差异（P<0.05）。我们观察到，10例死亡风险低于50%的患者中有7例在PICU入院前接受了强心治疗，这些患者在PICU入院时无血流动力学改变，且PRISM评分较低。我们建议，对于那些治疗可能改变PRISM评分中所包含生理变量的患者，应谨慎解释PRISM评分。
