[Preventive analgesia in patients undergoing open surgery for rotator cuff repair]

Preventive analgesia in orthopedic surgery is becoming increasingly important because post-surgical pain management is more pleasant for the patient and allows them to initiate rehabilitation early. With this premise we consider the following hypothesis. The perception of post-surgical pain at two, 12 and 24 hours with local infiltration into the surgical wound with ropivacaine plus systemic analgesia will be less compared to patients who infiltrate with saline into the surgical wound plus systemic analgesia.

A randomized double-blind, prospective randomized controlled clinical trial was conducted in the period January 2018 to August 2018.

The null hypothesis is rejected in the group valued at two hours and the null hypothesis is accepted in the groups valued at 12 and 24 hours.

Ropivacaine infiltration is an effective method for managing postoperative pain for the first 2 hours in open shoulder surgery procedures.
