The Diversity of Intestinal Microbiota in Patients With Different Sedative-hypnotics Undergoing Mechanical Ventilation

Summary

Bidirectional communication between the CNS and the GI tract - the brain-gut axis - occurs both in health and disease.Patients with mechanical ventilation in ICU (ICU) often meet the necessary nutritional needs. These patients often appear varying degrees of intestinal flora imbalance, such as diarrhea, vomiting, abdominal distension and other complications, which exert negative effect on treatment and prolong hospitalization time.So far，whether the sedative drugs used for a long time in mechanically ventilated patients will affect the diversity of intestinal flora or not has not been reported.The effects of different sedative drugs on the intestinal flora diversity need further study.Therefore, this topic will used midazolam and dexmedetomidine to study the effect on the diversity of intestinal microbiota.Meanwhile，the research will provide a theoretical basis for rational use of mechanical ventilation and sedative drugs.
