目的：分析精神病患者危急值，为预防罹患躯体疾病及早期诊治提供依据。方法对1000例精神病患者的1493项危急值的构成、分类、分布资料进行统计分析。结果本组出现频率最高的危急值前4项依次为：血清钾离子（32．9％）、肌红蛋白（14．3％）、氧分压（9．6％）和全血葡萄糖（8．2％）；血清钾离子、氧分压危急值以超低为主，血清肌红蛋白、全血葡萄糖危急值以超高为主；危急值多集中于8：00—12：00的时间段出现，以每年的3月—5月和7月—9月为高峰期。结论结合精神病患者的特点，定期分析危急值数据，了解其分布特征和规律，有利于合理安排医疗资源和精神病患者合并躯体疾病时的早期发现、早期诊断、早期治疗，提高救治成功率。“,”Objective To analyze critical values of mental patients in order to provide basis for preventing somatopathy and early diagnosis and treatment . Methods Constituents ,classifications and distributions of 1 ,493 critical values from 1 ,000 mental pa‐tients were statistically analyzed .Results The first 4 of the critical values with the highest frequency were in turn serum K + (32 .9% ) ,myoglobin (14 .3% ) ,partial pressure of oxygen (Po2 ,9 .6% ) and whole blood glucose(8 .2% );serum K+ and Po2 critical value were ultralow ,myoglobin and whole blood glucose ultrahigh ;critical values mainly emerged from 8 :00 to 12 :00 ,peak time was month 3-5 and 7 -9/year . Conclusion Analyzing critical values in combination with the characteristics of mental patients regularly and mastering distributional characteristics and regularity are beneficial to plan medical resources reasona‐bly ,to discover ,diagnose and treat combined somatopathies early ,and to boost the achievement ratio of remedy .
