Summary
Arthroscopic shoulder surgery involves dynamic and severe postoperative pain. Interscalene
brachial plexus block (IBPB) provides adequate analgesia but the spread of local anaesthetics
administered causes a phrenic nerve block which entrains a non-negligible incidence of
Hemidiaphragmatic paralysis acute (HDPA).
This is a comparative, prospective, Unicenter, double-blind, two-arm, randomized and
controlled clinical trial. 48 patients will be included.
This RCT would demonstrate a low volume dose IBPB decrease the HDPA after IBPB in patients
undergoing SAS, by using spirometry and ultrasound and it will not provide inferior
postoperative analgesia according to opioid requirements of postoperative PCA in comparison
to standard volume dose used in current practice.
