Effects of Etomidate on Postoperative Circadian Rhythm Changes of Salivary Cortisol in Children

Brief Title

Effects of Etomidate on Postoperative Circadian Rhythm Changes of Salivary Cortisol in Children

Official Title

Phase 1 Study of Circadian Rhythm of Salivary Cortisol in Health Children ;Phase 2 Study of Circadian Rhythm of Salivary Cortisol of Children Undergoing Surgery Using Etomidate or Not Using Etomidate.

Brief Summary

      Etomidate is an unique drug used for induction of general anesthesia and sedation. Adrenal
      cortical inhibition by etomidate has received much attention. However wether the circadian
      rhythm and pulse secretion pattern of cortisol in children are the same as that in adults is
      not known. Moreover, the effect of etomidate on circadian rhythm changes and clinical
      outcomes has never been carefully studied in children undergoing surgery. Our hypothesis is
      that etomidate can relieve the changes of circadian rhythm of salivary cortisol in children
      for 24-48 hours,and this does not make clinical outcomes worse postoperatively.

Detailed Description

      -  Sample size assessment: Using formula to calculate the total number is 30.

        -  Statistical analysis: ANOVA

        -  Reporting for adverse events: During the period of study, if there is any severe adverse
           event happening, such as severe infection, severe low cortisol concentration threatening
           the patient's life we will stop the trial.
