          摘   要  目的  研究环泊酚在孕鼠与胎鼠体内的药动学特征,为环泊酚在剖宫产中的应用提供参考。方法  取孕鼠8只,尾静脉单
          次给予2.4 mg/kg环泊酚,分别于环泊酚给药后2、4、8、12、16、25、35、45、60、90 min取出1只胎鼠,然后同时采集孕鼠与胎鼠全血;
          采用高效液相色谱-串联质谱(HPLC-MS/MS)法测定孕鼠和胎鼠体内各时间点环泊酚血药浓度,计算各时间点胎鼠血药浓度与孕
          鼠血药浓度的比值(F/M值),并绘制F/M时间曲线,再采用DAS 2.0软件计算非房室模型药动学参数。结果  与孕鼠相比,胎鼠体
          内环泊酚的cmax、AUC0-90 min、AUC0-∞均显著降低,平均滞留时间(MRT)显著升高(P<0.05)。环泊酚的F/M时间曲线呈先上升后下降
          的趋势,F/M 值在 0.16~0.84 之间,且在 45 min 时达到最大值(0.84)。结论  环泊酚在孕鼠与胎鼠体内的药动学参数存在较大差
          异,其虽能透过胎盘屏障,但是在胎鼠体内的暴露量远低于孕鼠,有望成为剖宫产理想的麻醉用药。

          ABSTRACT    OBJECTIVE  To  study  the  pharmacokinetic  characteristics  of  ciprofol  in  pregnant  and  fetal  rats,  and  provide
          reference  for  the  application  of  ciprofol  in  cesarean  section.  METHODS  Eight  pregnant  rats  were  selected.  A  single  dose  of  2.4
          mg/kg  of  ciprofol  was  administered  via  the  tail  vein.  One  fetal  rat  was  selected  at  2,  4,  8,  12,  16,  25,  35,  45,  60,  and  90
          minutes  respectively  after  ciprofol  administration.  Subsequently,  whole  blood  samples  were  collected  simultaneously  from  both  the
          pregnant rats and fetal rats. HPLC-MS/MS method was used to determine the concentration of ciprofol in the bodies of pregnant and
          fetal  rats.  The  ratios  of  fetal-to-maternal  blood  concentrations (F/M  ratios)  at  each  time  point  were  calculated,  and  the  F/M-time
          curves  were  plotted.  Subsequently,  non-compartmental  pharmacokinetic  parameters  were  computed  using  DAS  2.0  software.
          RESULTS  Compared  with  pregnant  rats,  cmax,  AUC0-90 min  and  AUC0-∞  of  ciprofol  in  fetal  rats  were  decreased  significantly,  while
          MRT  was  increased  significantly (P<0.05).  The  F/M  curve  of  ciprofol  initially  increased  and  then  decreased,  and  between  0.16-
          0.84, reaching a maximum value of 0.84 at 45 minutes. CONCLUSIONS Ciprofol can penetrate the placental barrier, and there are
          significant  differences  in  pharmacokinetic  parameters  between  pregnant  and  fetal  rats.  Moreover,  the  exposure  level  of  ciprofol  in
          fetal  rats  is  much  lower  than  that  in  pregnant  rats.  Therefore,  ciprofol  shows  promise  as  an  ideal  anesthetic  agent  for  cesarean
          section delivery.
