Overview
Brief Summary
This research is expected to study ultrasonic measurement of internal jugular vein and inferior vena cava, which can be used as a good index to predict hypotension after anesthesia induction, and its measurement method is simple and quick.
Detailed Description
The induction of anesthesia is the process from the physiological state to the anesthetic state in a short period of time. Hypotension after anesthesia induction is closely related to many organ injuries. Gastrointestinal surgery patients' prohibition of fasting is an important mechanism of severe hypotension after anesthesia induction. At present, ultrasonic measurement of inferior vena cava and internal jugular vein has been proved to be a convenient and non-invasive means to evaluate patients' blood volume. The purpose of this research was to study the relativity between ultrasonic measurement of inferior vena cava and internal jugular vein and hypotension after anesthesia induction in patients.

Outcomes
Primary Outcomes
Incidence of hypotension after anesthesia Induction
Time Frame: within 12 hours after anesthesia induction
Hypotension can be diagnosed if one of the following conditions is true: (1) a decrease in mean arterial pressure of \> 20% compared to the baseline value (2) mean arterial pressure \< 60mmHg
Secondary Outcomes
- Ultrasonic measurement of inferior vena cava and internal jugular vein(within 1 hour before anesthesia induction)
