Inclusion criteria

Inclusion criteria: Age between 18 and 70 years, American society of anesthesiologists (ASA) physical status I to II and body mass index <35.

Exclusion criteria

Design outcomes

Primary

Measure	Time frame
Primary outcomes will include pain severity at rest using visual analog scale (VAS) at PACU 2,4,6,12,18 and 24 h postoperatively. Pain will be assessed at rest only because the surgeons restrained the active movement of the operated shoulder. Time (in min) from the end of local anesthetics administration to the first rescue analgesic request (i.e. intravenous morphine bolus) which correspond to VAS >4. The number of patients who requested IV bolus morphine, overall morphine consumption in the first postoperative day. Number of patients satisfied or unsatisfied from analgesia at the end of postoperative day.	—

Secondary

Measure	Time frame
Evaluation of postoperative respiratory function; a chest radiograph will be done for all patients during the postoperative period and incidence of oxygen desaturation, pneumothorax, dyspnea and phrenic nerve palsy will be recorded during the first postoperative day. Opioid related side effects; (postoperative nausea and vomiting respiratory depression, pruritus and sedation) during the first postoperative day. Undesirable blockade of nerves or anatomical areas not involved in the surgery (cervical plexus, recurrent laryngeal nerve or forearm and hand) and block related complication (persistent paraesthesia, weakness and tingling) at the end of first postoperative day.	—
