Overview
Brief 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.
Detailed 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

Arms & Interventions
15 ml local anesthetic
in this group of patients the peng block was performed with 15 ml of ropivacaine, whose dose was obtained on the weight
Intervention: Ropivacaine
20 ml local anesthetic
in this group of patients the peng block was performed with 20 ml of ropivacaine, whose dose was obtained on the weight
Intervention: Ropivacaine

Intervention: Ropivacaine
Outcomes
Primary Outcomes
NRS evaluation
Time Frame: 24h post-op
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.
Secondary Outcomes
- NRS variation in time(24 h)
