          摘  要  目的  分析复方磺胺甲噁唑(简称“TMP/SMZ”)及其代谢物N-乙酰基磺胺甲噁唑(NSMZ)血药峰浓度(cmax )与危重症患者
          临床疗效及不良反应的相关性。方法  回顾性收集2023年12月至2025年1月海南省人民医院重症监护室(ICU)使用TMP/SMZ
          治疗的危重症患者资料,按治疗后是否成功分为成功组和失败组。采用简单线性回归和 Spearman 相关分析法分析 TMP cmax、
          SMZ cmax及NSMZ cmax与临床疗效及不良反应的相关性;采用受试者工作特征曲线(ROC)预测不良反应发生时的截断值。结果  在
          入住ICU 24 h内急性生理与慢性健康评分Ⅱ(APACHE-Ⅱ)≥15分的危重症患者中,成功组患者的SMZ cmax显著高于失败组(P<
          0.05)。TMP/SMZ 每日总剂量与 TMP cmax、SMZ cmax呈正相关(P<0.05)。TMP cmax与肝毒性和肾毒性、SMZ cmax与肝毒性、NSMZ
          cmax与肾毒性有相关性(P<0.05)。TMP cmax预测肾毒性和肝毒性的截断值分别为7.25、6.63 μg/mL,SMZ cmax预测肝毒性的截断值
          为 138.00 μg/mL,NSMZ cmax预测肾毒性的截断值为 60.76 μg/mL。结论  入住 ICU 24 h 内 APACHE-Ⅱ≥15 分的危重症患者中,
          SMZ cmax与治疗成功存在关联。TMP cmax≥6.63 μg/mL、SMZ cmax≥138.00 μg/mL时,患者的肝毒性发生风险显著增加;TMP cmax≥
          7.25 μg/mL、NSMZ cmax≥60.76 μg/mL时,患者的肾毒性发生风险显著增加。

          ABSTRACT   OBJECTIVE  To  analyze  the  correlation  of  the  peak  blood  concentration (cmax )  of  compound  sulfamethoxazole
         (TMP/SMZ)  and  its  metabolite  N-acetyl  sulfamethoxazole (NSMZ)  with  clinical  efficacy  and  adverse  reactions  in  critically  ill
          patients.  METHODS  The  data  of  critically  ill  patients  treated  with  TMP/SMZ  in  various  ICU  of  Hainan  General  Hospital  from
          December  2023  to  January  2025  were  retrospectively  collected.  The  patients  were  divided  into  success  group  and  failure  group
          based on the treatment outcome. Simple linear regression and Spearman correlation analysis were used to analyze the correlation of
          TMP cmax, SMZ cmax, and NSMZ cmax with clinical efficacy and adverse reactions. The receiver operating characteristic curve (ROC)
          was  used  to  determine  the  cutoff  values  of  cmax  for  predicting  the  occurrence  of  adverse  reactions.  RESULTS  Among  critically  ill
          patients with an acute physiology and chronic health evaluation Ⅱ (APACHE-Ⅱ) ≥15 points 24 h of check-in at ICU, SMZ cmax
          of success group was significantly higher than failure group (P<0.05). The daily total dose of TMP/SMZ was positively correlated
                                                             with TMP cmax and SMZ cmax (P<0.05). TMP cmax was significantly
