To Observe the Clinical Effect of Femoral Nerve Block With Low Concentration of Ropivacaine Based on DPN Grading

Condition(s) studied

Investigational drug(s) / intervention(s)

Different DPN ratings: According to the TCSS grading scale, DPN patients were graded into different grades, and the mild and severe groups and the control group were selected to observe the clinical effects between the three groups

Study summary

The purpose of this study was to quantitatively standardize the performance of patients with DPN with different course of disease using high-frequency ultrasound, and to design experiments to verify the conclusion that DPN patients with peripheral nerve damage increased nerve sensitivity to local anesthetic drugs and increased block time, and to achieve the same blocking effect by using low-concentration local anesthetic drugs, so as to reduce the probability of complications such as transient nerve injury, severe nerve injury, and local anesthetic poisoning.
