Design outcomes

Primary

Measure	Time frame
We measured the distance between catheter orifice and C5/C6 nerve by CO2 contrast-enhanced ultrasonography technique in the recovery room and at 24 hours after the operation. Concurrently, patients were examined VAS score, decrease in perception of C5/C6 nerve area and manual muscle test (MMT) of biceps. We also examined the correlation between these distances and clinical scores.	—
