Clinical Trial Summary

This study is to investigate whether a different volume of ropivacaine, with the same prescribed dosage based on body weight, can affect block efficacy, duration and side effects in the first 24 hours postoperatively.

Description:

patients were divided into 3 groups on the basis of the volume of anesthetic given to perform the block. in every patient was assessed the nrs, the side effects, if any, and the need for analgesic drugs in the first 24 hour after surgery

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	presence of side effects	Monitoring the onset of side effects (nausea/vomiting/hypotension/dizziness/sensitive impareiment) in every group of patients in the first 24 hours every six hours	24 hours
Other	analgesic requirements	requirement of analgesic to control the pain, assessed every six hours	24 hours
Primary	NRS evaluation	Evaluate pain for every volume group in the first 24 hours post surgery using the Numeric Pain Scale (NRS) assigning a numeric value between zero (no pain) and ten (the worst pain ever felt). Absence of relevant pain is considered a NRS less than three.; Success of the block was defined as NRS=3.	24h post-op
Secondary	NRS variation in time	consider variation of pain, assessed with numeric Pain scale, for each group, every six hours	24 h
