The investigators hypothesized that a combination of suprascapular nerve block and lateral sagittal infraclavicular block of the posterior and lateral cords would provide good postoperative analgesia for patients undergoing shoulder arthroplasty.
The primary aims of this study were to document numeric rating scale (NRS, 0-10) and use of morphine equivalents during the first 24 hours after surgery. Secondary aims were to determine the incidence of diaphragm paresis 30 minutes after the block and to quantify postoperative hand grip force at 1 hr.

SSNB will be performed with 4 ml ropivacaine 5 mg/ml LSIB will be performed With 15 ml ropivacaine 7.5 mg/ml
Procedure: Peripheral nerve blocks
LSIB + SSNB
- NRS [ Time Frame: Postoperatively at 1 hour ]Pain on a 0-10 scale where 0=no pain and 10=unbearable pain
- The incidence ipsilateral hemidiaphragmatic paralysis after 30 minutes [ Time Frame: 30 minutes after the blocks ]Hemidiaphragmatic paralysis was defined as the absence of diaphragmatic motion during normal respiration, coupled with absent or (paradoxical) cranial diaphragmatic movement when the patient forcefully sniffed.
