It is of great importance to develop an effective anesthesia program to effectively ensure the progress of surgery.
This study developed an effective anesthesia program to effectively ensure the progress of surgery.
Discusses the effect of ultrasound-guided nerve block combined with dexmedetomidine anesthesia in lower extremity fracture surgery.
A total of 120 patients admitted to our hospital with lower extremity fractures from January 2017 to December 2019 were selected. The control group received an ultrasound-guided nerve block. The observation group was treated with dextromethomidine based on the control group.
The mean arterial pressure of T1, T2 and T3 in the observation group were significantly higher than that of the control group. The observation group’s heart rate (HR) times at T1 was significantly lower than that of the control group. The times of observation group’s HR at T2 and T3 was significantly higher than that of the control group. The recovery time was significantly lower than that of the control group. Six hours post-anesthesia, epinephrine and norepinephrine in the observation group were significantly lower than that of the control group, and the mini-mental state exam score of the observation group was significantly higher than that in the control group.
Ultrasound-guided nerve block combined with dexmedetomidine has a good anesthetic effect in the operation of lower limb fractures and has little effect on the hemodynamics of patients.
We will explore the clinical effect of this method of anesthesia in other operations.
