简要总结
The correlation between internal jugular vein variability during deep inhalation and the decrease in blood pressure during propofol induction.
详细描述
- Ultrasound records at least one quiet breathing cycle and one deep inhalation cycle to calculate IJVV
- Propofol was infused target-controlled at 4 μg/ml, and changes in arterial blood pressure within 3 minutes of propofol induction were observed.
- Aim to conduct a prospective observational study to evaluate the correlation between internal jugular vein variability during deep inhalation and the decrease in blood pressure during propofol induction.
