Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

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

Ropivacaine

Intervention Type DRUG

The local anesthetic was dosed on the patient's weight (50-59kg: 120mg, 60-61kg: 140mg, 70-79kg: 160mg, ≥80kg: 180mg)

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

Ropivacaine

Intervention Type DRUG

The local anesthetic was dosed on the patient's weight (50-59kg: 120mg, 60-61kg: 140mg, 70-79kg: 160mg, ≥80kg: 180mg)

30 ml local anesthetic

in this group of patients the peng block was performed with 30 ml of ropivacaine, whose dose was obtained on the weight

Ropivacaine

Intervention Type DRUG
