How to maintain the stability of circulation during anesthesia has always been a concern of clinicians, including shorting the preoperative fasting time under the condition of full preoperative preparation, and giving appropriate amount of nutrient solution in combination with the patient's situation 2~4 h before surgery to reduce the blood volume insufficiency of patients before general anesthesia induction, vasoactive drugs, etc. Among them, passive leg lifting experiment is widely recognized in the world. Although passive leg lifting has many advantages, it still has some limitations in the operation process. This study tried to find the corresponding head low and foot high Angle corresponding to the same hemodynamic changes caused by passive leg lifting.
For low head and high feet, studies have shown that 20 can reduce the incidence of hypotension during the induction period of general anesthesia in patients undergoing gastrectomy and has therapeutic effect on it, as well as reduce the use of vasoactive drugs during the induction period of general anesthesia. There were no perioperative complications.
The passive leg lift test can be repeated and does not overload the patient with fluid. However, there is no relevant research on the relationship between the two, which is exactly the innovation of this topic.
